These 4 x 4 inch reclosable poly bags are constructed from 4 mil polyethylene, delivering a thicker, more puncture-resistant barrier than standard 2 mil alternatives. The single-track zipper closure runs the full width of the bag, allowing repeated opening and closing without compromising the seal against moisture, dust, and contaminants.

The square format and durable film weight make these bags a practical choice for parts kitting, sample distribution, retail packaging, e-commerce fulfillment, and light industrial sorting. The 4 mil construction handles heavier or sharper small components that would stress thinner film, making them especially useful in hardware, electronics assembly, and manufacturing environments.

Bags meet FDA and USDA requirements, supporting use in food-adjacent and regulated applications. Dimensions reflect interior usable space. Each case contains 1,000 bags and is eligible to ship via parcel carrier.
