Common Questions
Q: How thick is 4 mil, and when do I need it?
A: 4 mil is about the thickness of a standard business card. Choose 4 mil bags when you're packaging heavier items, sharp-cornered products, or anything that needs extra protection during shipping. If you're just doing light-duty packaging, 2 mil bags may work fine — but 4 mil gives you peace of mind.
Q: Will a folded t-shirt fit in an 11x18 bag?
A: Yes! An 11x18 bag fits most standard folded t-shirts comfortably with room to spare. It's also great for leggings, tank tops, and smaller clothing items.
Q: Can I use these bags for food products?
A: Absolutely. These bags are made from FDA food-contact compliant virgin LDPE, so they're safe for packaging bulk candy, baked goods, and other food items for farmers markets or retail.
