The BSC PREFERRED MG3945 is a case of 1000 reclosable poly bags from the Minigrip Premium Red Line line, designed for parts storage, organization, and shipping applications across 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 protects contents from moisture and contamination. A large white write-on block printed on the bag face allows part numbers, quantities, or other identification to be written directly with a pen, eliminating the need for separate labels. These bags meet FDA and USDA specifications for food contact.
These reclosable poly bags are suited for use in parts rooms, service vans, warehouses, and shop environments where small components need to be stored, identified, and protected. The write-on block makes them especially practical for HVAC, plumbing, electrical, and pool service professionals who stock and sort loose hardware, fittings, fasteners, and small parts. Bags are sold in cases of 1000 units. Dimensions listed reflect inside usable measurements.
Designed as a general-purpose reclosable poly bag for parts storage, packaging, and organization in trade and industrial settings. This product is equivalent to part number S-294.
No tools or installation are required for use. Store bags flat in a clean, dry location away from direct sunlight to maintain material integrity. When writing on the white block, allow ink to dry before sealing to avoid smearing inside the bag. Dispose of or recycle used bags in accordance with local regulations.
