Cable bundle and wire harness kitting; heavy hardware assortment and fastener packaging; metal stamped and machined part staging bags; photographic negative and archive sleeve protection; industrial repair kit component bagging; retail specialty hardware and accessory packaging.
Features
Reinforced side-welded zipper provides secure closure and resists separation under load from heavy cable or hardware contents. 4 mil gauge resists puncture from sharp metal edges, connector pins, and cable jacket burrs. High-clarity film enables contents identification without opening the bag. Square 12x12 format accommodates coiled cables, flat wire harnesses, and mixed hardware assortments. FDA compliant for food-adjacent and general industrial packaging.

Common Questions
Q: How does 4 mil compare to standard 2 mil zipper bags for heavy hardware?
A: 4 mil LDPE provides twice the wall thickness of standard 2 mil bags, significantly reducing puncture risk from sharp fasteners, metal edges, and connector pins in heavy hardware kitting applications.
Q: Can the zipper withstand the weight of coiled cable?
A: Yes. The reinforced side-welded zipper track is designed to handle repeated closure under load from heavy cable coils and hardware assortments without track separation.
