Common Questions
Q: Why choose 6 mil over thinner poly bags?
A: 6 mil is considered heavy-duty — about twice the thickness of standard 3 mil bags. This extra thickness provides superior puncture resistance, better moisture protection, and longer-lasting durability. It's ideal for items that will be stored long-term, shipped without outer boxes, or handled frequently.
Q: What fits in an 18x18 bag?
A: These square bags are perfect for standard throw pillows (up to 18x18), decorative cushions, folded queen-size pillowcases, folded throws and blankets, sweaters, and other bulky soft goods. The flat design lays smooth for stacking and storage.
Q: Can I heat seal these bags?
A: Yes! LDPE poly bags seal beautifully with a standard impulse sealer. The 6 mil thickness creates a strong, professional seal. You can also simply fold over the top and secure with tape or ribbon for a cleaner look.
