Industrial Applications
The 40x54 size and 4 mil construction serve multiple commercial operations. Manufacturing plants use these bags to protect machined parts, automotive components, and assembled products during storage and inter-facility shipping. Warehouses rely on this size for bulk storage of textiles, soft goods, and seasonal inventory that requires dust and moisture protection. Distribution centers employ 4 mil bags for order consolidation and temporary staging of large items. The heavy-duty construction resists punctures from sharp edges, metal components, and hardware, making these bags suitable for industrial parts with protruding features.
Key Features

- Large Format: 40x54 inch capacity accommodates oversized items and bulk quantities
- Heat-Sealable: Compatible with impulse and constant-heat sealers for secure closures
- FDA Compliant: Virgin LDPE resin meets FDA requirements for food contact applications
- Made in USA: Domestic manufacturing ensures consistent quality and reliable supply
Material Properties
Low-density polyethylene (LDPE) offers excellent flexibility and conformability while maintaining strong puncture resistance at 4 mil gauge. The material remains pliable in cold storage environments and resists cracking during handling. LDPE provides good moisture barrier properties for protecting contents from humidity and light contamination. These bags can be heat-sealed using standard impulse sealers or automated bag sealing equipment.
Storage and Handling
Store bags in a cool, dry location away from direct sunlight. Poly bags ship flat in cartons of 50 for efficient storage. Each bag opens easily for loading and can be sealed manually with heat sealing equipment or twist ties. For high-volume operations, consider compatible automated bagging systems that can handle this size and thickness.
