The BSC PREFERRED PB3520 is a reclosable poly bag designed for storing and protecting products from moisture and contamination. Each bag features a single-track zipper that runs the full width of the opening, providing a secure, resealable closure. These bags meet FDA and USDA requirements, making them suitable for food-contact and regulated storage applications. Sold in cases of 1000, they are built for volume use in packaging, shipping, and parts organization environments. All dimensions listed reflect the inside usable dimensions of the bag.
These reclosable bags are used across a range of industries and applications where clean, reusable containment is required. Common uses include food storage, parts packaging, sample organization, and general supply storage. The FDA and USDA compliance rating makes them appropriate for facilities that handle consumables or food-adjacent materials. Their reclosable design supports repeated use, reducing waste in high-throughput operations.
Designed as an OEM-equivalent replacement for part number S-1690. Suitable for general reclosable poly bag applications across packaging, food storage, and parts containment use cases.
No tools or trade licensing are required to use these bags. Store in a clean, dry location away from direct sunlight and sharp objects to maintain bag integrity. Ensure the zipper track is fully engaged after each closure to maintain moisture protection.
