Common Questions
Q: What clothing items fit in a 16x18 poly bag?
A: This size comfortably fits most adult t-shirts, polos, and lightweight sweaters when folded. It also works well for pants, shorts, and multiple smaller items packaged together.
Q: What's the difference between 4 mil and thinner bags?
A: At 4 mil (0.004 inches thick), these bags are significantly sturdier than standard 1.5-2 mil bags. The extra thickness means better puncture resistance, easier handling, and a more premium feel — ideal for retail and shipping applications.
Q: Can I heat seal these bags?
A: Yes! LDPE poly bags seal cleanly with a standard impulse sealer. You can also fold and tape, or use twist ties for a simple closure.
