Common questions
Are these bags suitable for food packaging?
Yes. These 4 mil poly bags meet FDA and USDA specifications, making them compliant for food storage, snacks, and beverage protection. They provide excellent moisture and contamination barriers for food-grade applications.
What is the difference between 4 mil and thinner poly bags?
The 4 mil thickness offers puncture resistance, tear strength, and durability compared to thinner alternatives (2-3 mil). This makes them ideal for heavy-duty industrial applications, sharp objects, and rough handling during shipping and storage.
What closure methods work best with these bags?
These open-end flat bags can be sealed using twist ties for quick closures, bag tape for secure sealing, or impulse sealers for high-volume operations. Choose based on your production speed and security requirements.
How many bags are in each case and what is the cost per unit?
Each case contains 500 bags. Purchasing in bulk cases reduces per-unit costs and ensures consistent supply for ongoing operations, making them cost-effective for high-volume industrial packaging needs.
