4×7 inch heavy-duty LDPE flat poly bags for packaging drill bits, thread taps, dies, cutting inserts, and other small precision tools. The 4 mil gauge provides puncture resistance against sharp tool points, flutes, and cutting edges that routinely pierce lighter-gauge bags. Manufactured from 100% virgin Low Density Polyethylene resin meeting FDA and USDA specifications. 1,000 bags per carton.

Material Notes

LDPE (Low Density Polyethylene) at 4 mil provides the minimum gauge recommended for packaging sharp-pointed tools where 1.5 mil and 2 mil bags present a puncture failure risk. Virgin resin formulation meets FDA and USDA contact specifications. All gauges are nominal.

Use Case Notes

Standard jobber-length drill bits (1–6 inches long) and machine thread taps (0.5–5 inches long) fit well in a 4×7 bag. For longer drill bits (8 inches and above), a 4×9 or 4×10 bag is recommended. The 4 mil gauge is the standard for retail-packaged drill bit sets where the bag must survive point-load contact during handling and display.

Common Questions

Why 4 mil instead of 2 mil for small tool bags?
Drill bits, taps, and cutting inserts have sharp points and cutting edges that easily puncture 1.5 mil and 2 mil bags, especially under the point-load forces encountered during shipping and retail handling. The 4 mil gauge is the practical minimum for reliable containment of sharp-tipped tools.

Will a standard 1/2-inch drill bit fit in this bag?
Yes. A 1/2-inch jobber-length drill bit (approximately 6 inches long) fits comfortably in a 4×7 bag. Longer bits such as 12-inch or aircraft-length extensions require a longer bag.

Are these FDA compliant?
Yes. Manufactured from virgin LDPE resin meeting FDA and USDA specifications for incidental food contact.

Why Buy

The 4×7 footprint and 4 mil gauge cover the largest segment of individual drill bit and tap packaging needs in wholesale and OEM distribution. At 1,000 bags per carton, this is a dependable production item for tool manufacturers, fastener distributors, and industrial supply houses requiring consistent, puncture-resistant packaging at scale.
