Common Questions
Q: How much can these bags actually hold with the gussets expanded?
A: With both side gussets fully expanded, these bags can hold items up to roughly 8" wide x 8" deep x 21" tall. For flat items, they work great for pieces up to about 12" wide when the gussets lay flat.
Q: Can I heat seal these poly bags?
A: Yes! Polyethylene heat seals beautifully with a standard impulse sealer. You can also fold over and tape, use twist ties, or add ribbon for a decorative touch.
Q: Are these bags good for shipping handmade items from my Etsy shop?
A: Absolutely. Many of our customers use these as an inner protective layer before placing items in mailers. They keep products clean, dry, and professional-looking when customers open their packages.
