Custom Mylar Bags for Snacks丨Crunch Preservation & Retail Ready

Custom Mylar snack bags are specifically designed to lock in crispy texture and meet retail needs. Adopting a multi-layer structure with an aluminum foil core, they achieve Water Vapor Transmission Rate (WVTR) ＜0.01g/m²·24h and Oxygen Transmission Rate (OTR) ＜0.1cm³/m²·24h·atm through ASTM testing.

This significantly reduces damage to snacks from moisture and oxygen, maintaining a crispness retention rate of over 90%, far superior to ordinary plastic bags.

Crunch Preservation

Studies show that when ambient humidity ＞40%, the crispness of potato chips decreases by 30% in 2 hours; when oxygen transmission rate ＞0.5cm³/m²·24h·atm, a rancid taste develops in 72 hours.

Custom Mylar bags feature an aluminum foil composite layer, achieving Water Vapor Transmission Rate (WVTR) ＜0.01g/m²·24h and Oxygen Transmission Rate (OTR) ＜0.1cm³/m²·24h·atm (tested per ASTM F1249/D3985 standards). Combined with nitrogen flushing, the crispness retention rate exceeds 90% (data from PMMI, the Association for Packaging and Processing Technologies, 2023).

Causes of Crispness Loss

Humidity

A 2022 experiment published in the Journal of Food Science (USA) placed freshly fried potato chips in environments with different humidity levels (40%, 50%, 60% relative humidity) and measured crispness using a texture analyzer (unit: N; higher values indicate greater crispness).

The results showed that at 40% humidity, the crispness of potato chips decreased from 12N to 8.4N (a 30% reduction) in 2 hours; at 50% humidity, it dropped to 9N in 1 hour and only 4.8N (a 60% reduction) after 4 hours; at 60% humidity, crispness decreased by 25% in just 30 minutes.

Different snacks absorb moisture at significantly different rates. Rice cakes and crispy jujubes have a skeleton porosity 30% higher than potato chips (observed via scanning electron microscopy).

Tests by Germany’s Fraunhofer Institute found that at the same 50% humidity, the crispness of rice cakes decreased by 40% in 1 hour, twice as fast as potato chips.

A South American corn chip brand once experienced a 22% return rate (2023 internal brand report) after shipping products to Southeast Asia (where humidity often exceeds 70% during transit), as the crispy chips turned into “soft cakes” upon arrival.

Oxygen

Fats in snacks (such as palm oil in potato chips and natural oils in nuts) oxidize when exposed to oxygen, first developing a rancid taste and then damaging the structure.

The oxidation process occurs in three stages: first, fat molecules are “attacked” by oxygen to form peroxides (primary oxidation); then they decompose into odorous substances such as aldehydes and ketones (secondary oxidation); finally, even structural proteins are oxidized and broken down.

The European Food Safety Authority (EFSA) stipulates that the peroxide value (PV, a measure of oxidation) of nuts should be ＜1 meq/kg (milliequivalents per kilogram); values exceeding 5 meq/kg result in a distinct rancid taste.

A 2023 experiment by Germany’s Max Rubner Institute placed peanuts containing 20% fat in packaging with an Oxygen Transmission Rate (OTR) of 0.5cm³/m²·24h·atm: after 72 hours, the PV rose to 6.2 meq/kg (exceeding the standard);

When the OTR was reduced to 0.1cm³/m²·24h·atm (Mylar bag level), the PV was only 0.8 meq/kg (meeting the standard) after 72 hours.

Higher fat content increases sensitivity to oxygen. Lay’s potato chips (USA) contain approximately 35% fat; when packaged in ordinary PE bags (OTR 1500cm³/m²·24h·atm), a rancid taste develops in 48 hours;

When switched to Mylar bags, the PV remained ＜1 meq/kg throughout the 6-month shelf life (2023 brand quality inspection data).

Pressure

Pressure levels vary by scenario: stacking 3 layers on supermarket shelves (20cm per layer) results in a pressure of approximately 1.5kg/cm² on the bottom bags;

During long-distance transportation by truck, vibration combined with stacking can cause local pressure to reach 3kg/cm².

Pressure simulation tests by Germany’s Fraunhofer Institute using a texture analyzer showed that under 2kg/cm² pressure, the crispness of potato chips decreased by 40% in 1 minute and 60% after 5 minutes;

Due to their hard outer shells, nuts only experienced a 20% crispness reduction under the same pressure, but the internal kernels were deformed.

A U.S. snack brand once used ordinary plastic bags for potato chips: during transportation to Canada, icy winter roads caused trucks to brake suddenly, leading to stacking and crushing of goods. Upon arrival, consumers complained that “half the chips were soft,” resulting in losses exceeding $500,000 (2022 logistics report).

After switching to Mylar bags with bubble buffer layers, the soft chip rate decreased from 35% to 2% in similar incidents.

Temperature

A 2021 study by the U.S. Department of Agriculture (USDA) found that when temperature increases from 25℃ to 35℃, the viscosity of potato chip fats decreases by 40%, making them more likely to seep out of structural gaps, removing flavor and loosening the structure.

The chocolate coating on crispy rice cakes has a melting point of approximately 34℃; when left in a car in summer (temperature exceeding 40℃), the coating melts and penetrates the rice cake skeleton, reducing crispness by 50% in 1 hour (tests by Nestlé Research Laboratories, Switzerland).

A Nordic crispy oatmeal brand exporting to the Middle East (where summer temperatures often exceed 45℃) had a shelf life of only 3 months with ordinary packaging; after switching to high-temperature resistant Mylar bags (capable of withstanding 80℃), the shelf life was extended to 6 months (2024 brand supply chain report).

Mylar Bag Materials and Design

Outer Layer

The outer layer of Mylar bags is made of polyester film (PET), typically 12-25μm thick.

DuPont’s Mylar technical manual states that its tensile strength can reach 200MPa, equivalent to withstanding a pull force of 2000kg per square centimeter—even when stacked three layers high during storage, the bags will not deform.

Transparency is also excellent: a light transmittance of ＞90% allows consumers to clearly see the color of the snacks inside, such as the orange crunch of Cheetos (USA) and the yellow hue of Walkers potato chips (UK), attracting attention through the bag.

Testing with a friction tester (per ASTM D1894 standards) showed only slight surface scratches after 500 dry friction cycles, making it 3 times more durable than ordinary PE film (2023 PMMI test).

Middle Aluminum Foil Layer

With a thickness of 7-12μm, it appears thin but has a dense arrangement of metal atoms, preventing water molecules and oxygen from penetrating.

DuPont data: Water Vapor Transmission Rate (WVTR) ＜0.01g/m²·24h (tested per ASTM F1249), Oxygen Transmission Rate (OTR) ＜0.1cm³/m²·24h·atm (tested per ASTM D3985).

Compared to the WVTR of 20-30g/m²·24h for ordinary PE bags, this is a difference of over 2000 times.

A 2022 experiment by the University of California, Davis found that after 72 hours of UV exposure, the peroxide value of potato chips increased by 30%; with the aluminum foil layer added, this value remained almost unchanged.

Mars (Europe) uses this layer for M&M’s Peanut Chocolate exported to Africa (a region with strong sunlight), extending the shelf life from 4 months to 8 months (2023 brand supply chain report).

Inner Heat-Seal Layer

The innermost layer is a heat-seal layer made of food-grade PE or PP, 20-50μm thick.

Testing per ASTM F88 standards requires a seal strength of ＞3N/15mm, meaning a force of at least 3 Newtons (equivalent to the weight of approximately 300g) is needed to tear the bag, ensuring no air leakage during transportation.

Some high-end bags use modified PP, which has a lower heat-sealing temperature (120℃ vs. 160℃ for ordinary PP), reducing thermal damage to snacks.

Kellogg’s (USA) uses this inner layer for crispy cereal: the surface temperature only increases by 2℃ during sealing, 5℃ less than ordinary bags, preserving 8% more crispness (2024 brand quality inspection data).

Advanced Designs

Designed based on snack characteristics:

• Bubble Buffer Layer: Adding a layer of tiny inflated bubbles (diameter 5-1mm) between the Mylar base material and aluminum foil, similar to an air cushion in a tire. Tests by Germany’s Fraunhofer Institute showed that under 2kg/cm² pressure, the internal pressure of bags with a bubble layer is dispersed to 0.5kg/cm², increasing the crispness retention rate of potato chips from 60% to 85%. Frito-Lay (USA) uses this design for potato chips, reducing the soft chip rate from 12% to 1% after bumpy truck transportation.

• EVOH Copolymer Layer: For moisture-sensitive snacks such as rice cakes and crispy jujubes, adding a layer of ethylene-vinyl alcohol copolymer (EVOH) increases moisture resistance by an additional 50%. Calbee shrimp crackers (Japan, export version for Europe and the USA) use this layer, resulting in only a 15% crispness reduction after 4 hours at 50% humidity (compared to a 25% reduction with ordinary Mylar bags).

• Transparent Window + Child-Resistant Closure: Children’s snack bags feature a small window cut into the aluminum foil layer (replaced with transparent PET) to allow parents to see the contents; additionally, a push-and-turn safety closure is added, requiring a push and half-turn to open with a pull force of over 5N (per ASTM F963 toy safety standards), making it inaccessible to children. Gerber (USA) uses this design for baby rice cakes, resulting in zero complaints about accidental opening (2023 Nielsen retail feedback).

Lamination Process

Multiple layers are bonded using polyurethane (PU) adhesive, with a coating weight of 3-5g/m² (too thick affects transparency, too thin causes delamination).

DuPont tests show that this adhesive maintains consistent viscosity within the range of -40℃ to 80℃, preventing delamination during transportation in northern winters or storage in southern summers.

After lamination, the material is cured in an aging oven (50℃ for 24 hours) to fully set the adhesive, achieving a peel strength of ＞5N/15mm (no interlayer separation).

Size and Shape

For example, for 100g of potato chips, a 20% void ratio is reserved (to prevent crushing), and the bag length and width = potato volume ÷ thickness × 1.2.

Lay’s small packs (28g, USA) use 12cm×8cm stand-up pouches with a thickness of 0.08mm; family packs (198g) use 18cm×12cm pouches with a thickness of 0.12mm.

Stand-up pouches feature a triangular bottom gusset that allows the bag to stand upright on its own, remaining stable on supermarket shelves for easy access (upright stability test: no tipping when tilted at 45°).

Performance Verification

Experimental Testing

Test conditions are strictly set according to real-world scenarios:

• Humidity Group: Potato chips were placed in humidity chambers with different levels (40%, 50%, 60% RH at 25℃), and crispness was measured every hour. A 2023 experiment in Packaging Technology and Science (USA) showed that potato chips in ordinary PE bags had their crispness decrease from 12N to 3N (25% retention) after 24 hours at 50% humidity; the same batch of potato chips in Mylar bags maintained a crispness of 11.2N (96% retention) after 24 hours.
• Oxygen Group: Nuts containing 20% fat were packaged in materials with different OTR values, and peroxide values (PV) were measured after 72 hours (EFSA EU standard: ＜1meq/kg is acceptable). Data from Germany’s Max Rubner Institute: PE bags with OTR 1500cm³/m²·24h·atm had a PV of 2meq/kg (exceeding the standard); Mylar bags (OTR 0.1cm³/m²·24h·atm) had a PV of only 0.8meq/kg (meeting the standard).
• Pressure Group: A pressure machine was used to simulate stacking (2kg/cm²), and crispness changes were measured. Fraunhofer Institute reports: potato chips in ordinary bags had a 40% crispness reduction after 1 minute of pressure, while Mylar bags with bubble layers only had an 8% reduction.

Comparison with Ordinary Packaging

In 2023, PMMI (USA) conducted a horizontal comparison test, packaging the same batch of potato chips (100g, initial crispness 12N) in three types of packaging—Mylar bags, ordinary PE bags, and paper boxes with PE liners—and storing them at 25℃ and 50% humidity for 72 hours. The results are clearly presented in the table below:

Note: Tests conducted per ASTM F1249 (WVTR), D3985 (OTR), and D7127 (crispness) standards

By comparison, the WVTR of Mylar bags is 3125 times lower than that of PE bags, the OTR is 22500 times lower, and the crispness retention rate is 3.4 times higher than that of PE bags.

Market Research

In 2024, IRI, a European and American market research firm, tracked 12 snack brands (including Lay’s, Cheetos, and Kellogg’s) and found that after adopting Mylar bags:

• Reduced Texture Complaints: Before switching to Mylar stand-up pouches, 18% of consumer complaints about Lay’s potato chips were related to “lack of crispness” (2022 Nielsen data); after the switch, the complaint rate dropped to 3% in 2023, reducing the number of complaint calls by 10,000 per year (brand customer service report).
• Increased Repurchase Rate: After Mars’ Cheetos crunchy corn puffs adopted Mylar bags, the 12-month repurchase rate increased from 28% to 38% (IRI panel data), meaning 10 more repeat customers out of every 100 buyers.
• Reduced Returns: Among snack returns in the United States, 12% are due to “deteriorated texture” (2023 PMMI industry report). After Frito-Lay switched to Mylar bags, the proportion of such returns decreased from 15% to 4%, saving $800,000 in shipping costs per year (logistics department calculation).

Extreme Environments

The performance of Mylar bags has been verified in overseas cases of European and American brands:

• High Temperature and Humidity (Middle East/Southeast Asia): Mars (Europe) previously exported M&M’s Peanut Chocolate to Saudi Arabia (summer humidity 70%, temperature 45℃) using ordinary aluminum-plastic bags, with a shelf life of 4 months; after switching to Mylar bags with an EVOH layer, 2023 export data showed the shelf life extended to 8 months, doubling the inventory turnover rate of local distributors.
• Low-Temperature Transportation (North American Winter): A Canadian potato chip brand used Mylar bags (PU adhesive lamination, stable viscosity at -40℃) for transportation to areas near the Arctic Circle (temperature -30℃) by truck in winter. Upon arrival, the bags showed no cracks, and the crispness retention rate was 91% (2023 brand transportation report); previously, with ordinary PE bags, cracks occurred at -20℃, resulting in a 25% soft chip rate.
• Long-Term Storage (European Warehouses): Walkers potato chips (UK) stored in Mylar bags in a constant temperature warehouse (20℃, 40% humidity) for 12 months maintained a crispness from 12N to 11N (90% retention), while ordinary bags stored for 6 months dropped to 4N (33% retention) (2024 brand quality inspection records).

Quality Inspection

Quality inspection is performed on each batch of products:

• Barrier Property Sampling Inspection: Randomly select 5 bags, measure OTR with a MOCON oxygen permeability tester (USA-made), which must be ＜1cm³/m²·24h·atm; measure WVTR with an infrared humidity sensor, ＜0.01g/m²·24h (Lay’s supplier standards).
• Seal Integrity Test: Fill the bag with water and submerge it in a water tank (1m water depth), maintaining pressure for 5 minutes without water leakage (ASTM F2094 standard); or test in a vacuum chamber, evacuating to -80kPa with no air bubbles for 5 minutes (Frito-Lay standards).
• Mechanical Strength: Use a tensile testing machine to measure heat-seal strength (＞3N/15mm) and aluminum foil peel strength (＞5N/15mm); unqualified batches are fully returned (specified in Kellogg’s procurement contract).

Retail Ready

According to 2023 data from the National Retail Federation (NRF, USA), Mylar bags with Retail Ready design reduce retailer restocking time by 45%, reduce damage rate by 35%, and increase shelf space utilization by 28%.

Basic Features

Pre-Seal Integrity

Retail Ready Mylar bags undergo final sealing at the factory using a heat-sealing process—temperature controlled at 120-150°C for 0.5-1 second—ensuring a seal width of 3-5mm with no leakage.

2023 tests by Smithers Laboratories (USA) showed that the residual oxygen content inside such pre-sealed bags is ＜2% (compared to 5%-8% for ordinary unsealed bags), significantly extending the freshness of crispy snacks (e.g., potato chips, crackers): at 25°C and 60% RH, the crispness of potato chips in sealed bags (measured by texture analyzer as breaking force) maintained 85% of the initial value after 7 days, while ordinary bags only retained 50%.

Seal integrity is also verified through burst testing—pressurizing to 0.5psi and maintaining pressure for 5 minutes without leakage, with a pass rate of 99.2% (sample size 5000).

Stand-Up Pouch Structure

Stand-up pouches feature a folded bottom gusset design, made of 12μm aluminized Mylar + 25μm PE composite film, with a folding angle of 110°-120°, maintaining shape after 300 pressure tests (simulating shelf load, 5kg per test).

2023 actual measurements by Packaging Digest showed that this structure allows the bag to stand stably on shelves tilted at 15°, with a standing success rate of 98% (compared to ＜30% for ordinary flat bags relying solely on their own weight).

The display area is 35% larger than flat bags—for example, a 100g potato chip stand-up pouch has a front display area of approximately 180cm², while a flat bag only has 130cm², exposing 20% more product graphics on the shelf.

Easy-Tear Notch + Resealable Design

The easy-tear notch is designed as a continuous serrated edge with a depth of 2mm, and the pull force is strictly controlled at 1.5-2.0N (complying with ASTM D6192 standards).

2022 tests by the American Packaging Testing Center using a tensile testing machine on 1000 samples showed a 99% success rate for first-time opening by consumers, 27% higher than bags without easy-tear notches (72% success rate).

Resealing is achieved with a dual-track zipper made of food-grade PP, 5mm wide, maintaining a seal after 50 openings and closings (measured by pressure difference method, leakage rate ＜0.01cc/min).

In terms of humidity control, the humidity rise rate inside the bag after opening is 60% slower than that of non-resealable bags—at 30°C, the humidity of non-resealable bags rises from 45% to 70% in 24 hours, while those with zippers only rise to 55%, keeping remaining snacks crispy for an additional 2 days.

Hanging Hole/Display Assistance

A pre-punched circular hole with a diameter of 6mm is located in the center of the bag top (compatible with standard European and American shelf hooks, hook diameter 5.5-6.5mm).

2023 observations by the European Federation of Snack Packaging (FPE) showed that hanging display increases consumer visual capture rate by 50% compared to flat placement—flat placement is only visible within a 30° angle directly in front, while hanging is visible within a 60° angle above and below.

Vertical display capacity also increases by 40%—for example, a standard shelf layer (1m long) can hold 8 flat bags, but 12 hanging bags. The edge of the hole is rounded (radius 0.5mm) to avoid scratching other packaging during transportation.

Integrated Information Printing

Key information is concentrated on the front:

• Brand name (font height ≥3mm);
• Product image (occupying 30% of the front area);
• Net weight (bold font, 20% larger than the ingredient list);
• UPC-A barcode (size 29×25.93mm, complying with GS1 standards).

The complete ingredient list and nutrition label are printed on the back, with a font contrast ratio ＞70% (black on white or white on black), complying with FDA 21 CFR 101.2 requirements.

2023 tests by the National Retail Federation (NRF, USA) showed that cashiers scanning bags with integrated printing took 0.8 seconds per bag, 38% faster than bags with scattered information (1.3 seconds), and the error rate decreased from 5% to 1%.

Flexographic printing is used with a color difference ΔE ＜2 (measured by X-Rite spectrophotometer) to ensure consistent color across batches.

Comparison with Traditional Packaging

Restocking Time

2023 sample data from the National Retail Federation (NRF, USA) showed that the average restocking time per box of traditional packaging is 12 minutes, and the shelf preparation time per SKU (e.g., a certain flavor of potato chips) is 25 minutes.

From the same data, the restocking time per box of Retail Ready bags is 6.5 minutes, and the preparation time per SKU is 10 minutes.

After introducing Retail Ready bags in 2022, Hy-Vee, a supermarket chain in the U.S. Midwest, saved an average of 12 restocking hours per store per month, equivalent to hiring half a part-time restocker less.

Damage Rate (Transportation + Display)

Traditional packaging has poor impact resistance. Loose snacks packed in cartons are prone to crushing during transportation, and simple plastic bags lack a stand-up structure, causing upper layers to crush lower layers when stacked.

2023 tests by Smithers Laboratories showed that the transportation damage rate of traditional packaging is 18% (including crushing damage and bag rupture with leakage), and secondary damage caused by tipping and friction during shelf display adds another 5%, resulting in a total loss of 23%.

Retail Ready Mylar bags are made of 12μm aluminized film + 25μm PE composite, with a puncture resistance of 8N (ASTM D1709 standard), maintaining shape when stacked 5 layers high.

2023 NRF data showed that the transportation damage rate is 7%, and display damage is almost zero, with a total loss of 7%—61% lower than traditional packaging.

Sales Volume

2023 actual measurements by Packaging Digest showed that for 100g potato chips, the front display area of traditional flat bags is 130cm², only exposing the brand name and part of the image;

The Retail Ready stand-up pouch with a folded bottom gusset has a display area of 180cm² when standing, exposing 20% more product images and net weight.

2023 observations by the European Federation of Snack Packaging (FPE) showed that Retail Ready bags with 6mm hanging holes have a 50% higher consumer visual capture rate when hung (visible within a 60° angle above and below compared to 30° directly in front for flat placement), and vertical display capacity increases by 40% (8 flat bags vs. 12 hanging bags per 1m shelf layer).

NRF data showed that the weekly sales per unit shelf area of Retail Ready bags is 22/dm², compared to 15/dm² for traditional packaging—47% higher.

Convenience

Traditional simple bags lack easy-tear notches, requiring scissors or teeth to open, with a 72% first-time opening success rate (2022 tensile tests by the American Packaging Testing Center); once opened, they cannot be resealed, and the humidity of remaining snacks rises from 45% to 70% within 24 hours, resulting in a 40% decrease in crispness (measured by texture analyzer as breaking force).

Retail Ready bags feature continuous serrated easy-tear notches with a pull force of 1.5-2.0N (ASTM D6192 standard), achieving a 99% opening success rate in 1000 tests;

Equipped with 5mm dual-track zippers, the leakage rate is ＜0.01cc/min after 50 openings and closings, and the humidity only rises to 55% 24 hours after opening, maintaining 80% of the initial crispness (2 additional days of crispness).

2023 IRI consumer research showed that the repurchase mention rate of Retail Ready bags is 32%, compared to 12% for traditional packaging—167% higher.

Practical Value

Cost and Time Savings

2023 data from the National Retail Federation (NRF, USA) showed that traditional packaging requires 12 minutes to restock per box, while Retail Ready bags only take 6.5 minutes, saving 5.5 minutes per box.

Shelf preparation per SKU (e.g., a certain flavor of potato chips) takes 25 minutes with traditional packaging and 10 minutes with Retail Ready bags, saving 15 minutes.

After introduction in 2022, Hy-Vee, a supermarket chain in the U.S. Midwest, saved an average of 12 restocking hours per store per month—calculated at a local part-time restocker hourly wage of $15, saving $180 per month and $2,160 per year.

The annual restocking cost decreased from $8,500 with traditional packaging to $4,600, a savings of $3,900 (46%). For brands selling 10,000 units per month, the annual savings amount to $2,160.

Replenishment and Stockouts

In the Hy-Vee case, traditional packaged potato chips required 2 daily replenishments, while Retail Ready stand-up pouches only need 1 due to stable standing, reducing monthly replenishments by 30 per store.

The stockout rate decreased from 18% (traditional) to 14% (a 22% reduction). Based on the store’s monthly potato chip sales of 5,000 bags and a profit of $0.5 per bag, the monthly loss reduction is 5,000×(18%-14%)×$0.5 = $100.

Shelf organizing time also decreased—traditional packaging required 2 hours per week to straighten tilted bags, while Retail Ready bags required almost no organizing, saving 104 labor hours per year.

Shelf Space Utilization

2023 actual measurements by Packaging Digest showed that stand-up pouches for 100g potato chips have a display area of 180cm², 50cm² more (35% larger) than traditional flat bags.

When hung with 6mm holes, 12 bags can be hung per 1m shelf layer, 4 more than flat placement (a 40% increase).

2023 observations by the European Federation of Snack Packaging (FPE) showed that hanging bags have a 50% higher consumer visual capture rate than flat placement (visible within a 60° angle above and below compared to 30° directly in front for flat placement).

NRF data showed that the weekly sales per unit shelf area of Retail Ready bags is 22/dm², compared to 15/dm² for traditional packaging—47% higher. After a brand adopted hanging hole bags, sales on the same shelf increased from 120 bags per week to 180 bags, a 50% growth.

Distribution

73% of retailers prioritize purchasing Retail Ready products (2022 NRF survey) because they eliminate the need for unpacking and organizing.

After a snack brand adopted Retail Ready bags in 2023, it entered 200 new supermarkets in the United States within 3 months—2 months faster than traditional packaging (which took 5 months).

During distribution, retailer acceptance time per SKU decreased from 10 minutes to 3 minutes (mainly checking seals and printing), allowing the brand to distribute to an additional 5 stores per month on average.

Amazon Warehousing prioritizes shelving Retail Ready packaged goods, resulting in 20% higher exposure. The brand’s FBA inventory turnover period shortened from 45 days to 30 days.

Convenience and Sales

2022 tests by the American Packaging Testing Center showed that Retail Ready bags have an easy-tear notch pull force of 1.5-2.0N (ASTM D6192 standard), achieving a 99% opening success rate in 1000 tests—27% higher than bags without easy-tear notches.

The 5mm dual-track zipper maintains a leakage rate of ＜0.01cc/min after 50 openings and closings, with humidity rising from 45% to 55% 24 hours after opening (compared to 70% for traditional bags), preserving 80% of initial crispness (2 additional days of crispness).

2023 IRI research showed that the repurchase mention rate of Retail Ready bags is 32%, compared to 12% for traditional packaging—167% higher. After Lay’s limited regional edition adopted Retail Ready bags, weekly average sales increased by 38%, higher than the 15% average growth of the same category.

Reduced Transportation Costs

2023 tests by Smithers Laboratories showed that Retail Ready bags are made of 12μm aluminized film + 25μm PE composite, with a puncture resistance of 8N (ASTM D1709 standard), maintaining shape when stacked 5 layers high.

The transportation damage rate is 7% (compared to 23% for traditional packaging), a 61% reduction. During warehousing, bags can be packed tightly, increasing space utilization by 30% compared to loose packaging. For a brand transporting 10 tons of snacks per month, using Retail Ready bags eliminates the need to rent one additional storage cabinet (saving $200 per month).
