Common Questions
Q: How big is this bag when fully opened?
A: With the gussets expanded, this bag opens to approximately 18" wide by 16" deep by 40" tall — large enough for oversized blankets, pillows, large gift baskets, or bulky craft items. The side gusset design creates a box-like shape that accommodates three-dimensional items.
Q: Can I heat seal these bags?
A: Yes! Polyethylene heat seals easily with a standard impulse sealer. You can also fold and tape, or use twist ties for a quick closure that's easy to reopen.
Q: What's the difference between side gusset and bottom gusset bags?
A: Side gusset bags (like these) have expandable panels on each side, making them ideal for wide, bulky items. Bottom gusset bags expand at the bottom to stand upright — better for items you want to display vertically.
