Common questions
Are these bags FDA and USDA approved for food contact?
Yes. These 4 mil reclosable poly bags meet FDA and USDA requirements, making them safe for direct food contact, including snacks, candy, dried goods, and frozen items. This compliance eliminates sourcing risk for food manufacturers and retailers.
What is the difference between 4 mil thickness and lighter alternatives?
4 mil thickness provides puncture resistance, tear strength, and durability compared to 2-3 mil bags. This material extends bag lifespan, reduces product loss from damage during shipping and storage, and justifies the investment through lower replacement costs.
Can these bags be reused or recycled?
Yes. The reclosable zipper design enables multiple reuse cycles, reducing packaging waste and total cost of ownership. The LDPE material is also recyclable through standard plastic recycling programs, supporting sustainability goals.
How does the full-width zipper improve performance versus standard closures?
The single-track zipper extending the full 6" width ensures consistent, secure sealing across the entire bag opening, maximizing moisture and contamination protection. This design prevents partial sealing issues and extends shelf life for sensitive products like food, pharmaceuticals, and hygroscopic materials.
