Common questions
Are these bags food-safe for direct contact with consumables?
Yes. These 4 mil poly bags meet FDA and USDA specifications, making them suitable for food storage and packaging applications without regulatory concerns or compliance gaps.
What thickness and durability level do 4 mil bags provide?
4 mil thickness offers puncture and tear resistance ideal for tools, hardware, and heavy items. This thickness balances durability with cost-efficiency, outperforming lighter 2-3 mil bags while maintaining reasonable per-unit pricing.
How do I seal these open-end poly bags?
Packrift offers three closure methods: Twist Ties for quick manual sealing, Bag Tape for secure adhesive closure, or Impulse Sealers for high-volume industrial operations requiring consistent, tamper-evident seals.
Why choose virgin polyethylene over recycled material?
100% virgin polyethylene ensures consistent clarity, strength, and contamination-free material, critical for regulatory compliance and protecting sensitive products. Recycled blends may contain impurities affecting product safety and visibility.
