Common Questions
Q: What size items will fit in a 28x40 poly bag?
A: These bags comfortably fit adult coats, large blankets, queen-size comforters (compressed), wedding dresses, and other bulky items up to about 27 x 39 inches when laid flat.
Q: Is 4 mil thick enough for shipping heavy items?
A: Yes — 4 mil is considered heavy-duty for poly bags. It resists punctures and tears during shipping, making it ideal for items with buttons, zippers, or firm edges that might poke through thinner bags.
