Common Questions
Q: Why choose 4 mil thickness over thinner bags?
A: At 4 mil, these bags are heavy-duty grade — ideal for items with sharp edges, heavier contents, or products that need extra protection. Standard bags run 1-2 mil; 4 mil is designed for tougher jobs where durability matters.
Q: Can I use these bags for food items?
A: Yes! The virgin LDPE resin meets FDA/USDA specifications for food contact. Great for storing dry goods, baked items, or protecting food products during shipping.
Q: How do I seal these bags?
A: You can fold over the top and tape, use twist ties, or heat seal with a bag sealer or impulse sealer for a professional, tamper-evident closure.
