These 3 x 4 inch reclosable poly bags are built at 8 mil thickness, placing them in the super heavyweight category for demanding applications where standard 2 or 4 mil film is insufficient. A full-width track zipper runs the entire opening, delivering a secure resealable closure that holds up through repeated open-and-close cycles without seal degradation.

The 8 mil film resists punctures and abrasion from metal parts, fasteners, hardware, and other dense or sharp-edged contents, making these bags well suited for industrial parts packaging, kitting operations, and parts distribution. FDA and USDA compliance also qualifies them for food-contact use in food processing, specialty retail, and laboratory environments.

Interior dimensions reflect inside bag dimensions. Each case contains 1000 bags, supporting high-volume packaging lines and ongoing facility replenishment. Cases are eligible to ship via parcel carrier.
