Minigrip® 4 x 4 inch reclosable poly bags are made from 2 mil polyethylene and feature a single-track, heavy-duty zipper that spans the full bag width. The zipper allows repeated opening and resealing without replacing the bag, and all listed dimensions reflect interior usable measurements. Optical clarity throughout the film allows contents to be identified at a glance.

These bags meet FDA and USDA specifications for direct food contact, making them a practical choice for food service portioning, pharmaceutical sample packaging, nutraceutical components, and small hardware or electronic parts. The reclosable seal also provides a reliable barrier against moisture and airborne contamination during storage and handling.

Constructed from virgin polyethylene for consistent gauge and seal integrity, the bags ship via parcel carrier in cases of 1000. The compact square format suits component kitting, retail display inserts, and lab specimen containment where a controlled, resealable enclosure is needed.
