Common Questions
Q: How thick is 4 mil and when do I need it?
A: 4 mil is about the thickness of a standard manila folder — noticeably sturdy and puncture-resistant. Choose 4 mil when you're shipping items, packaging products with zippers or buttons that could poke through, or when durability matters more than minimizing material.
Q: Will a folded t-shirt fit in a 15x18 bag?
A: Yes! A standard folded adult t-shirt (around 10x12 when folded) fits perfectly with room to spare for a packing slip or thank-you card. This size also works great for sweaters and larger garments.
Q: Can I heat seal these bags?
A: Absolutely. LDPE poly bags seal beautifully with a standard impulse sealer. You can also use tape, fold-over with a sticker seal, or leave open for easy access.
