Flat Poly Bags 5″ x 7″ 6 mil 1000/Box

Router Bit & Carbide Insert Packaging Bags 5″ x 7″ — 6 mil LDPE | 1,000/Box

5 x 7-inch flat poly bags in 6 mil LDPE, packed 1,000 per box. At 6 mil, these bags are at the top of the standard LDPE gauge range, designed specifically for small, sharp, or abrasive items where lighter gauges routinely fail. Router bits, carbide inserts, small end mills, and precision stamped parts with cutting edges require this gauge to prevent bag puncture during individual packaging and transit.

Specs: 5″ x 7″ | 6 mil | LDPE | 1,000/Box

Applications:

• Router bit and spiral flute end mill individual packaging
• Carbide insert and indexable tooling bagging for distribution
• Small precision stamping and blanking part packaging
• Knife blade and small sharp metal fabrication part bagging
• Abrasive tool and grinding wheel segment packaging

Features:

• 6 mil LDPE — maximum standard gauge for small, sharp, high-risk puncture items
• 5″ x 7″ format sized for most standard short router bits, inserts, and small precision parts
• Bottom seal construction with durable side welds for reliable bag integrity under load
• Heat sealable, tieable, stapleable, or tapeable closure
• Made from 100% virgin LDPE resin

Material Notes:

At 6 mil, LDPE provides the highest puncture and abrasion resistance available in the standard flat poly bag format. This gauge is appropriate when sharp-edged small parts routinely puncture 3–4 mil bags during loading, stacking, or transit. The extra film thickness also reduces the risk of surface scratching on polished or ground tool surfaces during bag-on-bag contact in storage bins.

Use Case Notes:

The 5 x 7-inch format is appropriate for router bits up to approximately 4.5 inches in shank length, most standard carbide insert sizes, and small precision stamped or machined parts. For longer router bits or extended shank tooling, a longer bag format (5 x 10 or 5 x 12) in 6 mil is recommended. 1,000 per box supports high-volume individual tooling packaging operations in cutting tool distribution and industrial supply.

Common Questions:

Q: Why is 6 mil necessary for small bags?
A: Small bags are often loaded with items whose edges or tips make direct contact with the bag film during insertion and handling. Router bits, carbide inserts, and precision stamped parts have sharp geometries that penetrate lighter gauges under minimal pressure. 6 mil absorbs this contact stress without bag failure.

Q: Can 6 mil LDPE bags be heat sealed?
A: Yes, but they require higher dwell time settings and a sealer rated for heavy-gauge film. Test seal settings on a sample run before full production to confirm seal integrity at the required throughput speed.

Q: Are these bags suitable for long-term tooling storage?
A: Yes. LDPE at 6 mil provides durable moisture and dust protection for tooling stored in bins, drawers, or packaging during extended inventory holding periods.

Why Buy:

1,000 per box provides economical stock for individual tooling packaging operations. The 6 mil gauge is the correct specification for sharp-edged precision tooling that would compromise standard packaging film, reducing bag failure rates and the labor cost of repackaging damaged items.
