Autobag 3″ X 5″ 3 mil Pre-opened Bags on a Roll 1500 per Roll

Industrial Hardware & Sharp Parts Autobag Bags 3×5 — 3 mil LDPE

Heavy-duty pre-opened bags on a roll in a 3×5 format for auto bagging equipment and semi-automated packaging lines where sharp, abrasive, or dense small parts require additional puncture resistance. The 3 mil LDPE wall provides significantly more durability than light-duty alternatives, making this format suited to industrial hardware, machined components, and similar high-contact products. Made from 100% virgin LDPE resin with bottom and side seal construction.

Specs: 3″ x 5″ | 3 mil | LDPE | Pre-Opened / Auto-Style | 1,500/Roll | FDA/USDA Compliant

Applications

• Industrial fastener and hardware auto-bagging (screws, bolts, nuts, anchors)
• Machined metal component and precision part packaging on production lines
• Drill bit tip and cutting insert individual packaging
• Small valve and fitting component kitting
• Dental and medical instrument component auto-packaging
• Heavy small-parts retail kitting for hardware distribution

Features

• 3 mil wall thickness resists puncture from sharp edges, threaded fasteners, and machined surfaces
• Pre-opened format feeds directly into standard tabletop auto baggers and production line bag feeders
• Bottom and side seal construction provides dual-axis bag strength under load
• 1,500 bags per roll for sustained production run capacity
• Low-haze optical quality for product identification through the bag
• Compatible with heat sealing, stapling, taping, or twist-tie closure

Material Notes

Manufactured from 100% virgin Low Density Polyethylene (LDPE) resin to FDA/USDA specification standards. The 3 mil gauge doubles the wall thickness of standard 1.5 mil auto-style bags, providing greater resistance to puncture and abrasion when packaging metal parts, sharp edges, or weighted components. All gauge listings are nominal.

Use Case Notes

The 3×5 format at 3 mil is purpose-suited for small, heavy, or sharp industrial components where light-duty bags fail on high-speed bagging equipment. The additional wall thickness also reduces the bag deformation that can cause misfeeds on auto bagging machines when loading dense or angular products.

Common Questions

Q: What auto bagging equipment is this compatible with?
A: These pre-opened bags are designed for tabletop auto baggers and production line bag feeders that accept roll-format bags. Verify roll width, core size, and bag pitch specifications against your equipment manufacturer’s requirements before ordering.

Q: Why 3 mil instead of 1.5 mil for small parts?
A: 3 mil provides significantly greater puncture resistance for sharp-edged components (fasteners, machined parts, drill bits) that would pierce lighter-gauge bags during auto bagging cycles, causing jams and rejects. Use 1.5 mil for soft or smooth products and 3 mil where abrasion and puncture are concerns.

Q: Are these bags food safe?
A: Yes. Made from FDA/USDA compliant LDPE resin, these bags are suitable for food-contact packaging when properly sealed.

Why Buy

A purpose-matched heavy-duty auto-style bag for industrial operations that need roll-format machine compatibility without sacrificing the wall strength required for sharp or dense small parts. The 1,500-bag roll count minimizes changeover frequency on production lines where throughput and uptime are priorities.
