Fully Customizable Bottom Filled Flat Ziplock Bags for Pre-Rolls & Vapes – B5

This product employs a multi-layer composite structure (e.g., BOPP/AL/PE or BOPP/VMPET/PE) with a thickness of 5.1 mil (0.13 mm). It integrates a food-contact safety layer, a high-barrier layer, and a durable outer layer, specifically designed to protect sensitive contents. It features a PE food-contact layer, compliant with FDA 21 CFR 177.1520 standards, ensuring safe product contact and meets stringent regulatory requirements.

Leveraging HP Indigo digital printing and multi-layer composite technology, the product combines exceptional visual appeal with robust physical protection. It complies with international certifications such as FDA, ensuring safety and regulatory adherence. The fully digital workflow supports rapid, small-batch customization, reducing production lead times by 15-20 days compared to traditional gravure printing.

Our packaging materials comply with U.S. FDA food-contact standards (21 CFR 177.1520) and have passed authoritative SGS testing, ensuring they are free from heavy metals and SVHC substances. The moisture and oxygen barrier performance strictly meets the standards (WVTR ≤ 15 g/m²·24h, OTR ≤ 0.5 cc/m²·24h), providing stable protection for products with specific requirements regarding the storage environment’s temperature and humidity control.

Utilizing HP Indigo 20000/25K digital printing and relying on a 7-color enhanced gamut (CMYK+OVG) to cover 97% of the Pantone color system, with a ΔE color difference ≤ 2. The technology supports precise adaptation to various materials (metallized Mylar, aluminum foil) and surface treatments (matte/gloss, spot UV), ensuring high-quality presentation of the design.

Keeping pace with global Herb packaging trends, we provide design solutions that meet evolving regulatory needs. The size (2.25″ × 6.25″) is optimized for pre-rolls and vapes, and configurations like child-resistant zippers can be incorporated to help brands establish a differentiated advantage in regulated markets.

This product is designed for businesses with high demands for packaging protection, compliance, and brand presentation. Its three-layer composite structure (food-grade PE contact layer + high-barrier layer + durable outer layer) and a thickness of 5.1 mil (0.13mm) provide comprehensive protection surpassing ordinary single-layer bags, making it particularly suitable for the following sectors:

Compliant Herb Product Brands

This bag is an ideal choice for CBD or THC brands selling pre-rolls and vape cartridges. The available child-resistant (C1-Type) zipper option directly meets stringent regulatory requirements. Simultaneously, the aluminum foil or metallized Mylar material offers high barriers against moisture and oxygen (WVTR ≤15 g/m²·24h), effectively preserving product flavor and active ingredients while blocking light and odors, ensuring product stability and discretion throughout the shelf life.

Premium Vape & Atomizer Manufacturers

The bag size (2.25″ x 6.25″) is optimized for a snug fit with a single vape pen or atomizer, preventing movement during transit. The material boasts good puncture resistance and temperature tolerance, protecting delicate vape hardware and glass cartridges. Furthermore, the high-quality printing surface, available in glossy or matte finishes, significantly enhances the Ease of Opening experience and the product’s perceived value as a gift item.

High-Value Traditional Chinese Medicines & Herbal Products

It provides professional protection for herbal raw materials, slices, and powders that are prone to moisture, odor transfer, or require protection from light. The aluminum foil material offers the strongest barrier, ensuring the long-term stability of medicinal components. The food-grade PE inner layer guarantees safe contact, the middle aluminum foil layer provides near-zero transmission of UV light and moisture, and the outer composite film (e.g., MOPP/BOPP/PET) grants the bag excellent low-temperature flexibility and tear resistance, enabling it to adapt to long-distance cross-border logistics and various climatic storage conditions.

“As a new brand, compliance is our top priority. We selected 4customprint’s B5 model aluminum foil bags, specifically opting for the four-layer PET/Matte Glue/AL/PE structure and the child-resistant (C1) zipper. This not only ensured the packaging’s WVTR value remains consistently below 15, effectively preserving the flavor of our pre-rolls, but the matte texture and precise Pantone color printing also enhanced the premium feel. Most importantly, the FDA compliance statement and SGS test reports provided with the shipment enabled us to pass our first channel audit on the first attempt, saving us weeks of preparation time.”

“One of our premium vape cartridges is highly sensitive to light and oxygen. The custom 2.25″ x 6.25″ aluminum foil bags provided by 4customprint perfectly fit the product dimensions, eliminating movement during transit. The AL aluminum foil barrier layer offers near-absolute protection against light and oxygen (OTR ≤ 0.5). According to our 6-month accelerated aging tests, the e-liquid retained over 99% of its original color and taste. The rounded corners and linear tear notch design also improved the user experience, leading to an 18% reduction in customer complaints.”

“We have a line of five different herbal tea blends, but traditional packaging came with high minimum order quantities and inventory pressure. 4customprint’s HP Indigo digital printing solution allowed us to produce five completely distinct designs within a single order, with a per-design MOQ of just 400 units. The turnaround time from design approval to receiving the first batch was only 12 business days. This allowed us to test the market at an extremely low cost. After two of the new products succeeded, we switched the order to large-scale gravure printing, significantly reducing our pilot production risk.”
