The BSC PREFERRED MG3950 is a case of 1000 reclosable poly bags designed for parts storage, organization, and moisture protection in shop and warehouse 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 dry. A large white write-on block printed on the bag surface accepts pen markings directly, eliminating the need for separate labels. All bags in this case meet FDA and USDA specifications for food contact applications. This product is sold as a single case of 1000 bags and is equivalent to part number S-295.
These bags are suited for trade shops, parts counters, supply rooms, and light industrial environments where organized, reusable storage is needed. Technicians and warehouse staff use them to sort small components, hardware, and parts by job or part number. The write-on block is especially useful in HVAC, plumbing, and electrical supply settings where quick part identification at a glance saves time. Sizes listed reflect inside usable dimensions of each bag.
General-purpose reclosable poly bags suitable for parts storage, packaging, and organization in trade supply, light industrial, and food-contact-approved applications.
No installation required. Store cases in a dry location away from direct sunlight to preserve bag material integrity. When writing on the block area, use a permanent marker or ballpoint pen for best legibility. Bags are intended for single or repeated short-term use and should be inspected before reuse to confirm zipper seal integrity.
