Flat Poly Bags 2″ x 3″ 4 mil 1000/CTN

2×3 in. 4 mil flat poly bags for carbide inserts, CNC tooling components, and precision machine parts. Made from 100% virgin Low Density Polyethylene (LDPE) resin meeting FDA and USDA specifications. Durable bottom seal construction. The heavy 4 mil gauge on this compact format provides exceptional puncture resistance for tungsten carbide inserts, precision-tipped tooling, and other very small, dense components where bag integrity directly protects part surface quality.

Material Notes

Constructed from 100% virgin Low Density Polyethylene (LDPE) resin. At 4 mil on a 2×3 in. bag, this is the heaviest standard gauge available for this compact format. The 4 mil wall resists puncture from tungsten carbide edges, precision-ground tooling, and dense metal components where lighter gauge bags would be compromised. LDPE film is moisture-resistant, protecting precision components against surface oxidation and contamination in storage environments.

Use Case Notes

The 2×3 in. format is sized for components in the quarter-inch to 1.5 inch range — typical of indexable carbide milling inserts (CNMG, WNMG, SNMG geometries), small precision ground pins, grub screws, and comparable micro-hardware. Used in the cutting tool distribution trade for individual insert protection during shipment from manufacturer to machine shop. The 4 mil gauge justifies the premium over lighter film in applications where carbide edges would penetrate 1 or 1.5 mil film.

Common Questions

Q: Why do you need 4 mil for such a small bag?
A: Carbide inserts and precision tooling have extremely hard, sharp-edged surfaces. At 2×3 in., the bag interior walls are close to component surfaces and 1 or 2 mil film would be punctured by typical carbide insert geometry. The 4 mil gauge is specifically selected for this type of content.

Q: Can these be heat sealed?
A: Yes. LDPE is heat sealable using standard impulse or direct heat sealers, including narrow jaw sealers appropriate for this small bag format. The open end can also be closed by tying, taping, or stapling.

Q: Are these FDA/USDA compliant for food contact?
A: Yes. Made from 100% virgin LDPE resin meeting FDA/USDA specifications for direct and indirect food contact applications.
