Common questions
Are these bags food-safe and compliant with regulations?
Yes. These 4 mil flat poly bags meet FDA and USDA specifications, making them approved for food storage, bakery items, and pharmaceutical applications. They're manufactured from virgin polyethylene, ensuring no contaminants from recycled materials.
What's the best way to seal these bags?
You have three sealing options: Twist Ties for quick, reusable closure; Bag Tape for secure, tamper-evident sealing; or Impulse Sealers for high-volume operations requiring consistent, heat-sealed closures. All are available separately.
Why choose 4 mil thickness over thinner alternatives?
4 mil provides heavy-duty durability that resists punctures and tears during handling, storage, and shipping of tools, hardware, and heavier items. It's significantly stronger than 2-3 mil bags while remaining cost-competitive for bulk purchasing.
How many bags are in each case and what's the shelf life?
Each case contains 500 bags. Virgin polyethylene bags have excellent shelf life when stored in cool, dry conditions away from direct sunlight, typically 2+ years without degradation.
