The BSC PREFERRED PB1549 is a case of 1000 poly bags designed with expandable sides and a fitted bottom to simplify packing bulky or irregularly shaped items. The expandable gusset construction allows the bag to conform to the contents rather than forcing the contents to fit a rigid form. These bags meet FDA and USDA specifications, making them suitable for food-contact and food-handling applications. Sizes listed for this bag reflect the inside usable space, giving technicians and packaging staff accurate dimensional planning. Bags can be closed with twist ties, bag tape, or impulse sealers depending on the line setup.
The PB1549 bags are used in packaging, distribution, food service, and light industrial environments where irregularly shaped or high-volume items require a flexible containment solution. The expandable side design reduces the need for multiple bag sizes on a packing line. Sold in cases of 1000 units, this product suits operations running moderate to high packing volumes. The fitted bottom provides stable upright support during filling, reducing tipping and spillage during manual pack operations.
Designed as a general-purpose poly bag compatible with standard twist-tie, bag-tape, and impulse-sealer closure methods used in food service, distribution, and light industrial packaging applications. Equivalent to part number S-3508.
No tools or utilities need to be shut off prior to use. When sealing with an impulse sealer, follow the sealer manufacturer's recommended dwell time and temperature settings for the bag film gauge. Store unused bags in a clean, dry location away from direct sunlight to prevent degradation of the poly material. Ensure the selected closure method is appropriate for the intended contents and any applicable food safety regulations.
