Frequently Asked Questions

Why use 4 mil for drive belts and timing chains?

Timing chains have metal links with sharp edges that puncture lighter poly bags during handling. The 4 mil gauge resists puncture and forms a moisture barrier that prevents rust on chain components before installation.

Will these fit folded serpentine belts?

Yes. Most passenger vehicle serpentine belts fold compactly to well under 18 inches. The 10×18 inch opening accommodates most folded automotive belts and timing chain sets without overstuffing.

Can I use these for other auto parts?

Absolutely. The 10×18 size works well for door handles, window regulators, wiper arm assemblies, and other mid-size automotive components requiring heavy-duty poly protection.
