Common Questions
Q: Will a king-size comforter fit in these bags?
A: Yes! The 30x42 size comfortably holds a folded king-size comforter. For down comforters that don't compress as much, fold in thirds lengthwise first, then roll or fold to fit.
Q: How thick is 3 mil and is it enough for storage?
A: 3 mil is considered heavy-duty for poly bags—about the thickness of a standard freezer bag. It's excellent for long-term storage, protecting against dust, moisture, and light handling. For extremely rough conditions, consider double-bagging.
Q: Can I heat seal these bags closed?
A: Absolutely. LDPE poly bags seal well with standard impulse sealers. You can also fold and tape, or use twist ties for items you need to access frequently.
