Extra-heavy 6 mil LDPE reclosable bags in a 12×15 in. format with a reinforced side-welded zipper designed for gasket kits, O-ring assortments, and industrial service parts that require repeated access and durable containment. The 6 mil wall resists puncture from metal edges and rubber compound particulate while the reclosable zipper provides secure re-sealing between service calls or inventory picks.

Material Notes

LDPE at 6 mil is the extra-heavy gauge classification, providing the highest standard puncture resistance for reclosable poly bags. The reinforced side-weld zipper construction bonds the zipper track to the bag at a wider seam than standard zip bags, maintaining zipper integrity under repeated loading and unloading of heavy service parts. FDA compliant virgin resin supports applications where components will contact food processing or food service equipment.

Use Case Notes

The 12×15 in. format accommodates most standard full-face and ring gasket kits for common pipe sizes up to 4 in., and large O-ring assortment packs of 200–400 pieces. For gaskets with sharp inner or outer edges, avoid overfilling to reduce stress on the zipper track during closure. For field service kit use, the reclosable format allows technicians to inventory remaining parts after a repair without repackaging.

Common Questions

Q: How many open-close cycles will the zipper handle?
A: The reinforced side-welded zipper is rated for repetitive open-close use in service parts environments. Failure typically occurs from overfilling or attempting to seal with sharp protrusions pressing against the zipper track from inside the bag.

Q: Are these FDA compliant?
A: Yes. Produced from 100% virgin LDPE resin meeting FDA and USDA specifications for indirect food contact use.

Q: What is the box quantity?
A: 250 bags per box.

Q: Is 6 mil necessary for gasket and O-ring storage?
A: For sharp-edged metal seat rings and split-ring gaskets, 6 mil prevents the pin-hole failures common in 2–4 mil bags during warehouse stacking and parts bin use. For soft rubber O-ring assortments only, lighter gauges are workable, but 6 mil adds meaningful durability at modest cost difference per bag.

Why Buy

Industrial service parts bags are a consumable where bag failure is a downstream problem — loose parts, contaminated kits, and re-packaging labor costs more than the original bag. Our 6 mil LDPE with reinforced zipper provides durable service kit packaging that holds up through multiple handling cycles from stocking to service call to field use.
