Common Questions
Q: What size garments fit in a 12x15 poly bag?
A: These bags comfortably fit standard folded t-shirts (adult S-XL), polo shirts, lightweight sweaters, and similar apparel. For bulkier items like hoodies, you may want to size up to a 14x18 or larger bag.
Q: What does "3 mil" thickness mean?
A: Mil measures thickness — 3 mil equals 0.003 inches. This is considered heavy-duty for poly bags, offering excellent protection against tears, punctures, and moisture. It's ideal for shipping where bags need to survive handling.
Q: Can I heat seal these bags?
A: Yes! LDPE poly bags seal beautifully with a standard impulse sealer or heat sealer. You can also fold and tape, use sticker seals, or tie with ribbon for a boutique finish.
