Protecting heavy automotive components and industrial castings demands a bag that won’t give under the weight or sharp edges of the contents. These 24 x 30 in. flat poly bags are built to 6 mil — an ultra-heavy gauge that holds up against engine blocks, transmission cases, cylinder head assemblies, differential housings, and other large machined or cast components. Made from 100% virgin LDPE meeting FDA/USDA specifications. Bottom seal or side-weld construction. Close by heat sealing, tying, taping, or stapling.

Frequently Asked Questions
What industrial components fit in a 24 x 30 bag?
A 24 x 30 in. bag accommodates most V6 and V8 engine short blocks, standard manual and automatic transmission cases, large differential housings, and similar heavy automotive components under approximately 23 x 29 in. For oversized assemblies, consider gusseted options or larger flat bags.
Why use 6 mil for heavy automotive parts?
At 6 mil, these bags resist puncture from casting burrs, machined edges, and bolt bosses that would immediately tear lighter-gauge bags. The extra thickness also provides a significant moisture barrier during warehouse storage and transit, helping prevent corrosion on bare metal surfaces.
Can these be used for food-contact applications?
Yes — made from FDA/USDA-compliant virgin LDPE, these bags meet food-safety material standards. However, at 6 mil and this size, they are primarily specified for heavy industrial and automotive packaging applications.
