5x7 Pre-Opened Auto Bags on Roll - Heavy-Duty 3 Mil for Automated Packaging
These 5x7 inch pre-opened poly bags on roll are engineered for high-speed automated packaging systems and efficient manual loading operations. The 3 mil heavy-duty LDPE construction handles industrial parts, hardware, and other applications requiring puncture resistance. Wound on standard 3-inch cores for compatibility with most auto-bagging equipment.

How Auto Style Bags Work
Auto style bags feature a pre-opened slit in the front and a perforated connection at the back. This design allows each bag to be quickly loaded—either by automated packaging machinery or by hand—then torn from the roll at the perforation. The result is dramatically faster throughput compared to picking individual bags from a stack.
Applications
The 5x7 size with 3 mil heavy-duty thickness serves demanding commercial and industrial packaging operations:
- Hardware & Fasteners: Screws, bolts, nuts, washers, and small metal parts
- Automotive Components: Gaskets, clips, fittings, and service parts kits
- Manufacturing: Assembly line component packaging and work-in-process bagging
- E-Commerce Fulfillment: High-volume picking and packing operations
- Food Packaging: Bakery items, candy, snacks—FDA compliant for direct food contact
- Medical & Lab Supplies: Non-sterile supply packaging and kitting
Key Features
- 3 Mil Heavy Duty: Puncture-resistant construction protects sharp or heavy contents
- Pre-Opened Design: Eliminates time-consuming bag opening on the packaging line
- Clean Perforations: Bags tear cleanly from the roll without jagged edges
- Virgin LDPE: Crystal-clear material for product visibility and professional presentation
- Standard Core: 3-inch core fits most auto-bagging dispensers and manual bag stands
Equipment Compatibility
These rolls work with automated baggers from major manufacturers including Autobag, Pacmac, and similar systems. For manual operations, pair with a roll dispenser stand to maximize packing efficiency. The consistent roll tension and perforation quality ensure reliable feeding through automated equipment.
