Engineered for Maximum Puncture and Tear Resistance

The number one benefit of 4 mil flat polyethylene bags is their uncompromising strength and resistance to tearing. This heavier 4 mil gauge is ideal for heavier items like nuts, bolts, or screws, or items that pose a puncture risk because they are sharp or oddly shaped. 4 mil thickness is twice the industry standard for poly bags, making it incredible resistant to tears and abrasions. Choosing 4 mil bags helps to reduce product loss and repackaging costs from transit because they are great at resisting blowouts.

Freezer-Safe & FDA-Approved for Extended Cold Storage

These 4 mil flat polyethylene bags are FDA and USDA approved for food storage in commercial kitchens and agricultural distributors. The material remains flexible and crack-resistant at extremely low temperatures and for long periods of time which helps prevent freezer burn and dehydration.

These bags are ideal for cold uses such as:

Bulk meats and seafood
Frozen portion controls
Ice storage
Temperature-sensitive medical or lab equipment
