Common Questions
Q: How do the gussets work on these large poly bags?
A: The 18" side gussets fold flat for storage but expand outward when you open the bag, creating a spacious interior that easily fits over bulky, irregular items like equipment or stacked boxes. Think of it like a box without the rigidity.
Q: Can I use these for food storage?
A: Yes! These bags are made from FDA food-contact compliant LDPE, so they're safe for storing dry goods, large baked items, or bulk food products. Perfect for bakeries packaging large cake boxes or caterers storing supplies.
Q: What's the best way to seal these bags?
A: For a permanent seal, use a heat sealer or impulse sealer. For temporary closure, fold the top and secure with packing tape, a twist tie, or a clip. Stapling works too if appearance isn't a concern.
