Common questions
What closure options work best with these 4 mil flat poly bags?
These bags accommodate multiple closure methods including twist ties, bag tape, and impulse sealers. Twist ties offer quick manual sealing for low-volume operations, bag tape provides tamper evidence, while impulse sealers deliver consistent, professional seals for high-volume packaging lines.
Are these poly bags suitable for food packaging?
Yes. These 4 mil polyethylene bags meet FDA and USDA specifications, making them approved for direct food contact. The 100% virgin material ensures food-grade quality without recycled content contamination.
How does 4 mil thickness compare to other poly bag options?
4 mil provides heavy-duty protection suitable for sharp or abrasive products like tools and hardware. It offers puncture resistance compared to thinner films (1-3 mil) while remaining cost-effective versus premium options like 6 mil or thicker specifications.
What is the typical shelf life and storage recommendation?
Polyethylene bags maintain integrity for 2+ years when stored in cool, dry conditions away from direct sunlight and extreme temperatures. Bulk case storage should be stacked on pallets to prevent deformation and allow for efficient inventory rotation.
