The BSC PREFERRED PB1597 is an expandable poly bag designed to accommodate bulky or irregularly shaped items without compromising the seal. The gusseted sides and fitted bottom allow the bag to conform around the contents, reducing wasted space and making loading faster. These bags meet FDA and USDA specifications, making them suitable for food-contact applications as well as general packaging use. They are compatible with standard closure methods including twist ties, bag tape, and impulse sealers. Sold in cases of 500 units, this product suits operations that require consistent, high-volume packaging solutions across food service, distribution, and industrial environments.
These poly bags are used in food processing facilities, commercial kitchens, distribution centers, and light industrial packaging lines. The expandable side gussets make them a practical choice when contents vary in size or shape. The fitted bottom provides a stable base for standing the bag upright during filling. Closures can be applied with twist ties or bag tape for quick sealing, or with an impulse sealer for a more permanent, tamper-evident result. Applications range from fresh or frozen food packaging to retail bagging of non-food items.
Designed as a general-purpose poly bag for food-contact and non-food packaging applications where expandable sides and fitted-bottom construction are required.
No tools are required for basic use with twist ties or bag tape. When using an impulse sealer, ensure the sealer jaw temperature and dwell time are set appropriately for the bag material thickness to achieve a consistent seal. Store unused bags in a clean, dry location away from direct sunlight to maintain material integrity.
