Common Questions
Q: Will these bags fit adult t-shirts?
A: Yes! The 12x18" size fits standard adult t-shirts (S through XL) when folded. You'll have about 2-3 inches of extra bag at the top for folding over or adding a closure.
Q: What does "3 mil" thickness mean?
A: Mil measures thickness — 3 mil is 0.003 inches, which is a heavy-duty poly bag. It's significantly more durable than the thin 1.5 mil bags, making it ideal for shipping and protecting items that need extra care.
Q: Can I seal these bags?
A: These are open-ended flat bags, so you can fold over the top and secure with tape, use a heat sealer for a permanent closure, or add a twist tie or ribbon for a decorative finish.
