The BSC PREFERRED MG3772 is a case of 1000 reclosable poly bags designed for parts storage, organization, and protection in trade and industrial environments. Each bag features a single-track, heavy-duty 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 identifiers to be written with a standard pen, eliminating the need for separate adhesive labels. These bags meet FDA and USDA specifications for food contact applications.
The MG3772 bags are suited for parts rooms, shop inventory, supply houses, and service vehicles where quick identification and reusable storage are priorities. The write-on block is particularly useful in HVAC, plumbing, and electrical supply environments where techs need to label small parts, hardware, fittings, or components on the job. Bags are sold in a quantity of 1000 units per case. Sizes listed by the manufacturer reflect inside usable dimensions of each bag.
This product is an equivalent replacement for part number S-15275. Designed for general-purpose parts storage, organization, and packaging across trade, industrial, and supply house environments.
No tools or installation are required for these bags. Store cases flat in a cool, dry location away from direct sunlight to maintain bag integrity and zipper function. Write-on block should be marked before loading contents for clear part identification. Handle zipper track carefully to avoid deforming the seal on individual bags.
