Extra-heavy 6 mil flat poly bags designed for industrial fasteners, small parts, and applications requiring maximum puncture resistance. These 3" x 5" heavy-duty poly bags are built for demanding industrial environments where standard bags simply won't hold up. The 6 mil thickness—twice as thick as standard 3 mil bags—provides exceptional puncture resistance for sharp-edged items like bolts, screws, washers, and metal components. Manufacturers, hardware suppliers, and industrial distributors rely on these bags to protect inventory and maintain organization in warehouses and production facilities. Made from 100% virgin Low Density Polyethylene (LDPE) resin that meets FDA/USDA specifications, these bags offer superior clarity for easy product identification while maintaining the strength needed for heavy-duty applications. The durable bottom seal ensures consistent performance even under stress, and the open-top design allows for multiple closure options—heat seal, tie, staple, or tape depending on your workflow requirements. Key Benefits: 6 mil thickness provides double the puncture resistance of standard bags Superior clarity allows instant visual identification of contents FDA-compliant virgin LDPE resin safe for food-contact applications Reinforced bottom seal withstands weight and sharp edges Multiple closure options for flexible packaging workflows Compact 3x5 size perfect for small hardware and component storage Specifications: 3" x 5" | 6 mil | LDPE | 1000/box | FDA-compliant | Open top Common Applications: Industrial fasteners (nuts, bolts, screws, washers), electronic components and small parts, jewelry findings and hardware, laboratory samples and specimens, automotive repair parts, medical device components, small tool organization, craft supplies and beads. What are 6 mil poly bags used for? 6 mil poly bags are extra-heavy-duty bags designed for industrial applications requiring maximum puncture resistance, such as packaging sharp metal fasteners, heavy hardware, or jagged components that would tear through thinner bags. What is the difference between 6 mil and 3 mil poly bags? 6 mil poly bags are twice as thick as standard 3 mil bags, providing significantly greater puncture resistance and durability. While 3 mil bags work well for lightweight items, 6 mil bags are necessary for sharp-edged hardware, heavy parts, or applications where bag failure could cause inventory loss or safety issues. Can these bags be used for food contact? Yes, these bags are manufactured from virgin LDPE resin that meets FDA/USDA specifications for food-contact applications, making them suitable for direct contact with food items when needed, though their primary design focus is industrial durability.
