These 16 x 20 inch reclosable poly bags are built from 8 mil polyethylene, placing them firmly in the super heavyweight category. The full-width track zipper delivers a secure, repeatable seal that holds up through consistent open-and-close cycles — a meaningful advantage over standard 2 or 4 mil bags when contents require both protection and accessible retrieval.

The combination of heavy-wall construction and resealable closure makes these bags a practical fit for industrial parts storage, hardware and fastener packaging, food manufacturing, retail display, and bulk material containment. Sharp-edged components, dense hardware, and moisture-sensitive goods all benefit from the added puncture and tear resistance at this thickness.

These bags meet FDA and USDA requirements for food-contact applications. All listed dimensions are interior measurements. Each case contains 250 bags and is eligible to ship via parcel carrier.
