Common Questions
Q: Will these bags fit a standard throw blanket or twin comforter?
A: Yes! The 20x30" size comfortably fits folded throw blankets (typically fold to around 15x20"), standard pillows, and even twin comforters when compressed. For bulkier king-size bedding, consider our larger sizes.
Q: How thick is 4 mil compared to other poly bags?
A: 4 mil is our heavy-duty option — about twice as thick as standard 2 mil bags. This extra thickness prevents punctures and provides better protection for items with buttons, zippers, or textures that could snag thinner material.
Q: Can I seal these bags closed?
A: Absolutely. These bags can be heat sealed, taped, or tied with ribbon or twist ties depending on your presentation preference. For shipping, we recommend heat sealing or sturdy packing tape for the most secure closure.
