Frequently Asked Questions

1.5 mil refers to the plastic thickness (0.0015 inches), making these bags ideal for medium-duty applications. This thickness balances durability with cost-efficiency, strong enough for food products, dry goods, and non-sharp items, while remaining economical for high-volume orders. For heavier items or sharp contents, consider upgrading to 2.0 or 3.0 mil alternatives.

Yes. These gusseted poly bags meet FDA and USDA food-contact specifications, making them compliant for packaging fresh produce, baked goods, deli items, candy, snacks, and other regulated food products without additional clearance.

The expandable gusseted sides allow the bag to widen and accommodate irregularly shaped products (breads, pastries, bundled items) without compression or damage. The fitted bottom provides a stable base that stacks neatly on shelves and in shipping containers, reducing wasted space and damage during transit.

These bags can be sealed using twist ties, bag tape, or impulse sealers. Twist ties offer quick manual closure for retail settings; bag tape works for heavy-duty industrial use; impulse sealers provide fast, airtight seals for high-volume food packaging operations.
