Commercial Applications
The 12x20 size paired with 3 mil heavy-duty thickness serves demanding packaging requirements across multiple industries. Apparel distributors use these bags for protecting sweaters, folded dress shirts, and heavy knitwear during storage and shipping. Textile operations rely on this size for fabric samples, cut fabric pieces, and finished goods that need puncture protection. Manufacturing and industrial facilities package metal parts, automotive components, and hardware kits where standard 2 mil bags would tear. Print shops and sign companies use the 12x20 format for protecting large format prints, posters, and mounted graphics.
Key Features
- 3 Mil Heavy Duty: Twice the thickness of standard bags for superior puncture and tear resistance
- Seamless Construction: Made from extruded tubing with no side seals that can split under stress
- Virgin LDPE Material: Clean, consistent quality with excellent clarity for product visibility

- Dispenser Packaging: Bags packaged in packs of 100 for cleanliness and convenience
Thickness Guide
The 3 mil thickness rating means these bags are approximately 0.003 inches (76 microns) thick. For reference: 1.5 mil bags suit light-duty dust covers and temporary storage. Standard 2 mil handles most general packaging needs. These 3 mil bags step up for heavy-duty applications where puncture resistance matters—think sharp metal edges, weighted items, or products requiring extra protection during extended storage.
