Common Questions
Q: What can I fit in a 12x30 poly bag?
A: These bags comfortably hold items up to 11" in diameter when rolled, and up to 29" long. They're perfect for standard poster sizes (11x17, 12x18) when rolled, architectural drawings, fabric bolts, and similar long-format items.
Q: What does 6 mil thickness mean, and do I need it?
A: Mil measures thickness in thousandths of an inch — 6 mil is about 0.006" thick. Choose 6 mil when you need extra protection for shipping, heavy items, or reusable storage. It resists punctures and tears far better than standard 2-4 mil bags.
Q: Can I heat seal these bags closed?
A: Yes! LDPE poly bags seal beautifully with standard heat sealers. The 6 mil thickness requires slightly more heat or dwell time than thinner bags. You can also fold and tape for a quick closure.
