Common Questions
Q: Will these bags fit a folded adult t-shirt?
A: Yes! A standard folded t-shirt measures about 10 x 12 inches, so these 16 x 20 bags give you plenty of room with space to fold over the top for a clean seal.
Q: What's the difference between 4 mil and 2 mil bags?
A: Mil measures thickness — 4 mil is twice as thick as 2 mil. For shipping apparel or anything that needs extra protection, 4 mil is the better choice. It resists punctures and tears much better during transit.
Q: Can I heat seal these bags?
A: Absolutely. LDPE poly bags seal beautifully with an impulse sealer. You can also fold and tape, use a sticker seal, or simply fold the top over.
