Common questions
Are these bags food-safe?
Yes. These 4 mil flat poly bags meet FDA and USDA specifications, making them suitable for food storage and food-contact applications when properly sealed.
What closure options do you recommend for these bags?
You can seal these open-end bags using twist ties, bag tape, or impulse sealers. Each method provides secure closure depending on your application and automation needs.
How does 4 mil thickness compare to thinner bags?
4 mil provides puncture and tear resistance compared to 2-3 mil bags, offering better protection for heavy-duty products, longer shelf life during storage, and fewer damaged shipments, reducing overall packaging waste and replacement costs.
Can I use these for outdoor storage?
While these polyethylene bags provide excellent moisture and dust protection, extended UV exposure may degrade the material over time. For long-term outdoor applications, consider storage in shaded areas or supplementary protection.
