3x4 in. 3 mil flat poly bags for small hardware, precision parts, and industrial components. Made from 100% virgin Low Density Polyethylene (LDPE) resin meeting FDA and USDA specifications. Durable bottom seal construction. The heavy 3 mil gauge on this compact bag size provides puncture and abrasion resistance for snap rings, retaining clips, circlips, carbide inserts, and other small but sharp or dense components requiring individual poly bagging.

Material Notes

Constructed from 100% virgin Low Density Polyethylene (LDPE) resin. The 3 mil gauge provides strong resistance to puncture and abrasion from dense metal components, tool inserts, and fine-edged hardware despite the small bag dimensions. LDPE film resists moisture vapor, protecting precision parts against corrosion in storage and transit environments.

Use Case Notes

The 3x4 in. format is sized for small components typically in the 1 to 3 inch range — snap rings, circlips, roll pins, e-clips, and similar precision hardware. At 3 mil, the bag is heavy enough to resist puncture from circlip sharp edges during filling, handling, and transit. This size and gauge combination is widely used in automotive parts distribution, bearing maintenance kits, and precision hardware wholesale operations where individual component bagging is required before assembly into kit packs.

Common Questions

Q: Why 3 mil on such a small bag?
A: Small, dense hardware components like snap rings, circlips, and carbide inserts have sharp edges relative to their size. The 3 mil gauge provides puncture resistance appropriate for these materials — a lighter 1 or 1.5 mil bag would be more vulnerable to edge penetration from this type of content.

Q: Can these be heat sealed for bulk kitting operations?
A: Yes. LDPE is heat sealable using standard impulse or direct heat sealers. The small format is compatible with narrow jaw sealers commonly used in component kitting. 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.
