Machined Part & Industrial Cutting Tool Bags 9" x 12" -- 6 mil LDPE | 1,000/Box

9 x 12-inch flat poly bags in 6 mil LDPE, packed 1,000 per box. At 6 mil, this is the heaviest-gauge standard LDPE bag in the flat poly category, appropriate for machined metal parts, industrial cutting tools, and fabricated components with sharp edges, protrusions, or significant mass that would puncture or tear lighter-gauge bags.

Specs: 9" x 12" | 6 mil | LDPE | 1,000/Box

Applications:

• Machined parts bagging — turned, milled, and ground metal components
• Industrial cutting tool packaging — drill bits, end mills, taps, and reamers
• Cast and forged metal component packaging for distribution
• Heavy fastener kitting — lag bolts, structural anchors, and heavy hex hardware
• Saw blade and abrasive tool individual bagging

Features:

• 6 mil LDPE — extra-heavy gauge for sharp edges, abrasive surfaces, and high-mass components
• 9" x 12" format accommodates most standard machined parts and cutting tool sizes
• Bottom seal construction with strong side welds for load-bearing integrity
• Heat sealable, tieable, stapleable, or tapeable closure
• Made from 100% virgin LDPE resin

Material Notes:

At 6 mil, LDPE provides the maximum puncture and tear resistance available in the standard flat poly bag format. The extra thickness absorbs contact stress from sharp-edged metal parts and prevents bag failure during packing, stacking, and transit. 6 mil LDPE is appropriate where 3–4 mil bags show signs of puncture or where components have sharp protrusions that compromise standard gauges.

Use Case Notes:

The 9 x 12-inch format accommodates most common machined part and cutting tool footprints. For parts with very long profiles, the tubing or gusseted format may be more appropriate. The 6 mil gauge is the correct choice when individual bagging is required for sharp, abrasive, or heavy metal components that must be protected from surface contact with each other during transit or warehouse storage.

Common Questions:

Q: When is 6 mil necessary versus 4 mil?
A: 4 mil handles most industrial hardware. 6 mil is appropriate when parts have sharp cutting edges (drill bits, end mills, blades), highly abrasive surfaces, or when bags show repeated puncture failures at 4 mil due to component geometry or weight.

Q: Can 6 mil bags be heat sealed?
A: Yes. 6 mil LDPE seals on standard impulse sealers but requires higher dwell time settings and a sealer rated for heavy-gauge film. Verify your equipment specifications before running a full production volume.

Q: Are these bags suitable for long-term parts storage?
A: Yes. LDPE at 6 mil provides durable moisture and surface protection for long-term storage of machined or fabricated metal components.

Why Buy:

1,000 per box provides economical stock for high-volume machined parts or cutting tool packaging operations. The 6 mil gauge handles the most demanding packaging scenarios in metal fabrication, tool distribution, and industrial MRO environments where lighter gauges regularly fail.
