What fits in a 4" x 4" bag?

A 4" x 4" flat bag holds items up to about 3.5" wide and 3" long, leaving room at the top to heat-seal it. It is a good fit for small parts, jewelry, coins and samples. At 6 mil (extra heavyweight), it is made for the heaviest, most puncture-prone loads.

Our 6 Mil low-density polyethylene (LDPE) flat poly bags are the strongest option for super heavy-duty applications. Designed to be puncture- and tear-resistant, these extra heavy-duty clear poly bags are perfect for packaging industrial parts, sharp tools, hardware, and other heavyweight products. They keep items protected from dirt, dust, and moisture while maintaining excellent clarity.

Best for super heavy-duty packaging – Recommended for sharp or heavy industrial products.
Made from 6 Mil (.006”) low-density polyethylene (LDPE) for maximum strength and durability.
Seamless tubing construction – No side seals or slits that can rip.
Dispenser-packed poly bags – Sizes 36” wide and under come in packs of 100 for convenience and cleanliness.
Heat sealable open-top design – Seal with a heat sealer, tape, or twist tie.
FDA & USDA compliant – Safe for direct food contact.
100% recyclable – Sustainable packaging made from 100% virgin raw materials.
