Applications
The 4 mil thickness makes these bags ideal for operations handling components that would tear lighter-gauge material. Manufacturing facilities use this size for packaging machined parts, castings, and assemblies with protruding edges. Automotive aftermarket distributors rely on 4 mil bags for brake components, gaskets, and hardware kits. Maintenance operations stock this size for organizing tools and replacement parts. The 16x18 footprint accommodates medium-to-large components while the heavy gauge prevents punctures during handling and transit.
Key Features
- 4 Mil Heavy-Duty Construction: Resists punctures from sharp edges, threads, and rough surfaces
- Seamless Tubing Design: No side seals to split under stress—uniform strength across the entire bag
- Virgin LDPE Material: Consistent clarity for part identification and FDA compliance for food contact when needed
- Flexible Yet Durable: LDPE conforms to irregular shapes while maintaining protective barrier
Thickness Guide
At 4 mil, these bags sit at the heavy-duty end of the flat poly spectrum. For reference: 1.5-2 mil handles light-duty dust protection, 2-3 mil covers general-purpose packaging, and 4 mil delivers industrial-grade protection for parts with sharp edges or significant weight. Choose 4 mil when standard bags would risk tearing during handling or storage.
