Common questions
Are these poly bags food-safe?
Yes. These bags meet FDA and USDA specifications, making them approved for food storage, snack packaging, and other food-contact applications. They're ideal for candies, baked goods, and dry food items requiring regulatory compliance.
What's the best way to seal these open-end bags?
Packrift offers three sealing solutions: Twist Ties for quick, reusable closures; Bag Tape for secure, tamper-evident sealing; or Impulse Sealers for high-volume production efficiency. Choose based on your volume and closure requirements.
Why choose 4 mil thickness over thinner bags?
4 mil polyethylene provides heavy-duty puncture and tear resistance essential for protecting tools, hardware, and fragile items during shipping. Thinner bags risk failure; 4 mil ensures product safety and reduces damage-related returns.
How many bags will I receive in one case order?
Each case contains 1,000 individual 4x4" flat poly bags, providing significant volume at competitive bulk pricing. This case size is ideal for high-volume industrial operations and reduces per-unit costs.
