Common questions
Are these bags FDA and USDA compliant?
Yes. These 4 mil flat poly bags meet FDA and USDA specifications, making them suitable for food storage, pharmaceutical applications, and regulated industries requiring certified food-contact materials.
What's the difference between 4 mil and thinner poly bags?
4 mil thickness provides puncture resistance, tear strength, and durability compared to 2-3 mil bags. This heavier gauge protects sharp or heavy items better and withstands rough handling without splitting or leaking.
How should I close these open-top bags?
You have three options: use twist ties for quick, reusable closure; apply bag tape for secure, tamper-evident sealing; or use an impulse sealer for permanent, heat-sealed closure. All supplies are available at Packrift.
Why choose virgin polyethylene over recycled?
Virgin polyethylene ensures consistent quality, predictable performance, and eliminates contamination risks from recycled material. This is critical for food storage, pharmaceutical packaging, and applications requiring strict purity standards and compliance certifications.
