Common questions
What closure options work best with these 4 mil poly bags?
These bags close securely with twist ties, bag tape, or impulse sealers. Impulse sealers provide the strongest, most professional seal for shipping compliance, while twist ties offer quick closure for retail or storage applications.
Are these bags compliant with food packaging regulations?
Yes. These 4 mil poly bags meet FDA and USDA specifications, making them suitable for food storage, candy packaging, snacks, and other food-contact applications without additional certification.
How many bags are in a case and what's the typical shelf life?
Each case contains 500 bags. Polyethylene bags maintain their integrity for years when stored in cool, dry conditions away from direct sunlight, making bulk purchasing economical for high-volume operations.
