The BSC PREFERRED PB321 is a case of 500 lightweight, clear polyethylene poly bags designed to protect products from dirt, dust, and moisture during storage and shipping. Manufactured from 100% virgin, high-clarity polyethylene film, these bags meet FDA and USDA specifications, making them suitable for food-contact and regulated-environment applications. They are sold by the case and are a standard choice for packaging operations in distribution centers, warehouses, and light industrial facilities. Closing options include twist ties, bag tape, or impulse sealers, giving users flexibility in sealing method without additional specialized equipment.
These poly bags are well-suited for general-purpose packaging tasks in wholesale distribution, food handling, manufacturing, and supply chain operations. Their lightweight construction keeps material costs low while still providing reliable protection. The case format with 500 bags per unit supports high-volume packaging workflows where consistent supply and quick replenishment matter. Facilities handling trade supplies, parts, or food-adjacent products will find these bags a practical fit for everyday use.
Designed as a general-purpose poly bag compatible with standard impulse sealers, twist tie dispensers, and bag tape systems commonly used in warehouse and light industrial packaging applications.
No installation is required for poly bags. Handle film bags away from open flames or heat sources not intended for sealing. When using an impulse sealer, follow the sealer manufacturer's settings for polyethylene film thickness to avoid improper seals. Store unused bags in a cool, dry location away from direct sunlight to maintain film integrity.
