8x12 Heavy Duty Flat Poly Bags - 4 Mil Industrial Strength by LK Packaging
These 8x12 flat poly bags in 4 mil thickness deliver serious puncture resistance for demanding industrial applications. LK Packaging's heavy-duty LDPE construction protects sharp-edged parts, metal components, and hardware from damage during storage and transit. The generous 8x12 dimensions accommodate medium-sized parts while the 4 mil material shrugs off abrasion that would tear lighter bags.

Industrial Applications
The 4 mil thickness makes these bags ideal for operations handling metal parts, automotive components, and hardware assemblies. Manufacturing facilities use them for in-process parts storage and inter-department transfers. Maintenance and repair operations rely on heavy-duty bags for organizing fasteners, fittings, and replacement parts. Distribution centers stock this size for kitting operations where multiple components ship together. The 8x12 footprint fits small hand tools, electrical components, plumbing fittings, and machine parts that would puncture standard 2 mil bags.
Key Features
- Puncture Resistant: 4 mil material withstands sharp edges, burrs, and pointed parts without tearing
- Crystal Clear: Visual parts identification without opening bags speeds inventory and inspection
- Moisture Barrier: LDPE protects metal parts from humidity and prevents surface corrosion
- Dust Protection: Sealed storage keeps precision components clean until use
- Heat Sealable: Create permanent closures with standard impulse sealers for secure shipping
Thickness Guide
At 4 mil, these bags sit at the heavy-duty end of the flat poly bag spectrum. For reference: 1.5 mil handles lightweight items like clothing and paper goods; 2 mil works for general-purpose storage; 4 mil protects industrial parts with edges or weight. Choose 4 mil when contents might puncture thinner material or when long-term storage requires extra durability.
