The BSC PREFERRED PB3978 is a reclosable poly bag designed for parts storage, organization, and light packaging applications. Each bag features a single-track zipper that runs the full width of the bag, creating a secure seal that keeps contents clean and protected from moisture. A large white write-on block printed directly on the bag allows part numbers, descriptions, or other identifying information to be written with a standard pen, eliminating the need for separate labels. These bags meet FDA and USDA requirements, making them suitable for contact with food-grade and regulated products. Sold in a case of 1000 bags.
These reclosable poly bags are well suited for trade supply operations, parts counters, and distribution environments where quick identification and reuse are priorities. The write-on block is especially useful in HVAC, plumbing, electrical, and pool supply contexts where small components need to be labeled and stored efficiently. Because the bags are reclosable and reusable, they reduce waste in high-volume service environments. All dimensions listed reflect inside usable measurements of the bag.
Designed as a general-purpose reclosable poly bag suitable for parts packaging, storage, and organization in trade supply, distribution, and light industrial environments.
No tools or trade licensing are required to use these bags. Store cases in a dry location away from direct sunlight and heat sources to maintain bag integrity. When writing on the white block, allow ink to dry before sealing the bag to avoid smearing inside the closure.
