Applications

Used by art supply distributors and craft wholesalers for bagging paintbrush sets, palette knife kits, and artist tool assortments. Also used for long drill bit and auger bit packaging, taper candle retail sleeving, chopstick and cutlery set bagging for food service distributors, dowel rod and skewer packaging, and long-profile hardware components such as threaded rods and alignment pins.

Features

• Narrow 4″ width — snug fit for long, slim contents without excess bag volume
• 12″ length — accommodates most standard paintbrush handles, drill bits, and elongated retail goods
• 4 mil gauge — industrial-duty for puncture-prone contents including metal tools and hardware
• Heat-sealable — compatible with impulse and bar sealers for production-line closure
• Bottom seal construction — reliable base for upright or horizontal packaging
• 100% virgin LDPE resin — no regrind or recycled content
• 1,000 bags per carton — high-volume case quantity for production and fulfillment operations

Material Notes

Manufactured from 100% virgin Low Density Polyethylene (LDPE) resin meeting FDA and USDA specifications. 4 mil nominal gauge is classified as industrial-duty, providing substantial puncture and tear resistance for sharp-edged contents including drill bits, metal tools, and abrasive hardware. All gauges are nominal.

Use Case Notes

At 4″ wide x 12″ long, this bag is a close fit for most standard flat paintbrush handles (3–4″ wide when fanned out), individual drill bits up to 10″ in length, and chopstick and skewer sets up to 10–11″. The 4 mil gauge is heavier than typical art supply bags and provides extra protection for tool edges and tips that can puncture lighter gauges.

Common Questions

Q: Is 4 mil necessary for paintbrush packaging?
A: For art supply retail bags, 2 mil is often adequate. The 4 mil gauge is beneficial when bags are also used for metal tools, drill bits, or other sharp-tipped contents on the same packaging line, providing one bag specification that covers the full range of use cases.

Q: Are these bags FDA compliant?
A: Yes. The virgin LDPE resin meets FDA and USDA specifications, which covers food-adjacent uses such as cutlery sets, chopsticks, and disposable skewer packaging.

Q: Can these bags be machine loaded?
A: Yes. The open-top design is compatible with semi-automatic and automatic form-fill operations, and the 4 mil gauge resists tearing during high-speed handling.

Why Source These Bags

1,000-count carton quantity supports production-scale art supply and hardware packaging operations. The 4 mil gauge handles both soft-goods (brushes, sticks) and hard-goods (bits, pins) in the same bag SKU, reducing inventory complexity. FDA-compliant LDPE covers food service cutlery and skewer packaging alongside non-food applications.
