The BSC PREFERRED MG3777 is a case of 500 reclosable poly bags built around a single-track, heavy-duty zipper that runs the full width of each bag. The zipper closure keeps contents protected from moisture and contamination between uses. These bags are manufactured from polyethylene film with superior optical clarity, allowing contents to be identified without opening. The bags meet FDA and USDA specifications for food contact, making them suitable for both food-grade and general storage applications. Sold as a case of 500 units, the MG3777 is a standard choice for packaging, parts storage, and inventory management in commercial and trade environments.
These reclosable poly bags are used across a wide range of industries including food processing, parts distribution, hardware packaging, and general warehousing. The single-track zipper allows repeated opening and closing, extending the usable life of each bag. All dimensions listed for this product reflect the inside usable dimensions of the bag. Facilities requiring FDA- and USDA-compliant packaging for food contact applications will find these bags meet those regulatory standards without additional certification steps.
Designed as a general-purpose reclosable poly bag for food-grade and industrial packaging applications. This product is equivalent to part number S-774.
No installation is required for this product. Store cases in a clean, dry environment away from direct sunlight and heat sources to maintain bag integrity and clarity. Verify that the zipper track is fully engaged after loading contents to ensure a proper moisture-resistant seal. Follow applicable FDA and USDA handling guidelines when using these bags in food contact applications.
