Common Questions
Q: Will these bags fit a full-length coat or dress?
A: Yes! The 18 x 36 inch size accommodates most full-length garments when folded once. For very long items like formal gowns, you can fold the garment or consider our larger sizes.
Q: How thick is 4 mil and is it enough for shipping?
A: 4 mil is considered heavy-duty for poly bags — about the thickness of a standard freezer bag. It's excellent for shipping protection and resists punctures from hangers, buttons, or rough handling during transit.
Q: Can I heat seal these bags?
A: Absolutely. LDPE poly bags seal beautifully with standard impulse sealers. You can also use tape or twist ties if you prefer a reusable closure.
