Common Questions
Q: What's the difference between 4 mil and lighter poly bags?
A: Mil measures thickness — 4 mil is four-thousandths of an inch. That's roughly twice as thick as standard 2 mil bags. The extra thickness gives better puncture resistance and a more substantial feel, which matters for heavier garments or rough handling during shipping.
Q: Can I heat seal these bags?
A: Yes! LDPE poly bags heat seal beautifully with a standard impulse sealer. You can also fold over the top and secure with tape or a sticker for a quicker closure.
Q: Will a full-length winter coat fit in this bag?
A: Absolutely. At 20 x 42 inches, these bags accommodate most adult coats and long dresses. For bulkier items like down parkas, you may want to fold or compress slightly, or consider our gusseted options for more depth.
