Common Questions
Q: How much can these bags actually hold with the gussets expanded?
A: With the 18-inch side gussets fully expanded, these bags can accommodate items up to roughly 20 inches wide by 18 inches deep by 30 inches tall. Think large blankets, bulky sweater sets, or multiple folded garments bundled together.
Q: Is 1.5 mil thick enough for heavy items?
A: Yes — 1.5 mil is considered heavy-duty for poly bags this size. It handles the weight of bedding, clothing bundles, and similar merchandise without tearing. For extremely sharp or abrasive items, consider double-bagging.
Q: Can I heat seal these bags?
A: Absolutely. Polyethylene heat seals easily with a standard impulse sealer. You can also use tape, twist ties, or bag clips depending on your application.
