Common Questions
Q: How thick is 4 mil compared to regular poly bags?
A: 4 mil is considered heavy-duty — about twice as thick as standard 2 mil bags. This extra thickness provides puncture resistance and durability for hardware, parts, or anything with sharp edges. It's the go-to choice when you need bags that can handle rough handling.
Q: Can I heat seal these bags closed?
A: Yes! LDPE poly bags seal beautifully with a standard impulse sealer. You can also use twist ties, staples, or simply fold over the top. The 4 mil thickness creates a strong, secure seal.
Q: Are these bags food safe?
A: These bags are made from 100% virgin LDPE resin that meets FDA/USDA specifications for food contact. They're suitable for dry foods, candy, baked goods, and other food items.
