Common Questions
Q: How thick is 6 mil compared to standard poly bags?
A: At 6 mil (0.006"), these bags are about twice as thick as typical 3 mil poly bags. This extra thickness provides significantly better puncture resistance and durability — ideal for heavier items, parts with sharp edges, or anything that needs extra protection during handling and shipping.
Q: Will these bags fit an 11x17 art print with matting?
A: Yes! The 12x20" dimensions give you a full inch of clearance on each side of an 11x17 print, plus 3 inches of extra length for matting or to fold over for closure. They're perfect for protecting matted prints and photographs.
Q: Can I use these for food packaging?
A: Absolutely. These bags are made from 100% virgin LDPE resin that meets FDA and USDA specifications for food contact. They're suitable for packaging dry goods, baked items, or any food product that benefits from the heavy-duty protection.
