These 36" x 48" flat poly bags are manufactured from 100% virgin LDPE resin at 6 mil thickness. The extra-heavy gauge and large format make these bags suitable for protecting large CNC machined parts, industrial sub-assemblies, and finished mechanical components against moisture, contamination, and surface damage during warehousing and transit.
Specs: 36" x 48" | 6 mil | LDPE | FDA Compliant | 50/Box
Applications
- Large CNC machined parts — housings, flanges, bearing blocks
- Industrial sub-assembly packaging for shipment to OEM facilities
- Heavy press tooling and mold component protection
- Large automotive and heavy equipment parts — brackets, control arms, valve bodies
- Construction hardware and structural fastener pallet packaging
- Industrial finishing and anti-corrosion storage bagging
Features
- 100% virgin LDPE resin — FDA/USDA compliant
- 6 mil extra-heavy gauge — maximum puncture and abrasion resistance for sharp-edged metal parts
- Bottom seal construction for heavy load integrity
- Open top — compatible with heat sealing, stapling, taping, or twist-tie closure
- 50-count box for facility and shipping department stock
Material Notes
Low Density Polyethylene (LDPE) at 6 mil represents the heaviest standard gauge available in flat poly bag format. At this thickness, bags withstand contact with sharp metal edges, burrs, and machined features without tearing. Virgin LDPE resin provides a clean, non-reactive surface suitable for direct contact with precision-machined and finished metal components. Nominal gauges apply.
Use Case Notes
A 36" x 48" bag accommodates most industrial part sizes including large flanged housings up to approximately 34" in any flat dimension, valve body castings, press brake tooling sections, and comparable items. For items with sharp projections or irregular geometry, wrapping parts in foam or protective sheeting before bagging is recommended to prevent bag puncture and surface marking.
Common Questions
Q: What is the maximum weight these bags can hold?
A: At 6 mil LDPE, these bags have high tensile and puncture strength relative to standard gauges, but are not rated for specific weight capacities. For very heavy items, bags should be placed on a pallet or supporting surface rather than lifted by the open end. The bag is intended to provide moisture and contamination protection, not structural support.
Q: Can these bags be vacuum-sealed for corrosion protection?
A: LDPE bags can be evacuated with a chamber vacuum sealer and heat-sealed for corrosion protection applications. For VCI (vapor corrosion inhibitor) protection of metal parts, VCI poly bags are specifically formulated for that application and would be more appropriate than standard LDPE.
