Common questions
Are these bags suitable for food storage and shipping?
Yes. These 4 mil poly bags meet FDA and USDA specifications, making them appropriate for food-adjacent applications and regulated product storage. Verify specific food contact requirements with your regulatory compliance team.
What closure methods work best for these bags?
These open-top bags can be sealed using twist ties, bag tape, or impulse sealers. Impulse sealers provide the strongest, most professional closure for high-volume shipping and storage applications.
Why choose 4 mil thickness over thinner alternatives?
4 mil provides puncture resistance and durability for heavy-duty products like tools and hardware. The heavier gauge protects contents during rough handling while remaining cost-competitive at bulk volumes.
Can I use these bags for outdoor storage?
These bags work for temporary outdoor use but are optimized for indoor storage and shipping. Extended UV exposure may degrade polyethylene; consider UV-stabilized alternatives for prolonged outdoor exposure.
