Frequently Asked Questions
1. Are these bags suitable for direct food contact?
Yes. The inner PE layer is FDA-compliant (21 CFR 177.1520) for direct food contact. They are safe for dry foods, nutritional powders, and botanicals.
2. Do you provide physical samples before bulk orders?
Yes. Unprinted stock samples are available for quality and sizing verification. Custom printed samples require a setup fee and extend standard lead times by 5 business days.
3. Can these pouches be vacuum sealed?
No. These flat open-top pouches are designed for standard impulse heat sealing. They lack the textured channel structure required for domestic vacuum sealers.
4. What is the required format for custom print artwork?
We require vector files (.AI, .EPS, or .PDF) with all text converted to outlines. The minimum resolution for any embedded raster elements is 300 DPI.
5. Is double-sided printing available for this SKU?
The standard online configuration supports single-sided (front or back) 1-color printing. Double-sided printing is available via custom quote by contacting our sales team.
6. Are the materials recyclable or compostable?
No. The multi-layer PET/AL/PE laminated structure provides maximum barrier protection but is not locally recyclable or compostable in standard municipal waste systems.
