Customized Pre-Opened Auto Bags on Roll / PE Continuous Roll Packaging Bags

1. Product Details

  • Structure: Pre-opened bags on a roll, front side pre-opened, back side heat-sealed with perforated separation lines.
  • Material Options: PE, LDPE, HDPE, or modified co-extruded films.
  • Compatibility: Engineered for automatic bagging machines and tabletop auto-packers.
  • Custom Features: Optional bottom gusset, anti-static treatment, printing, or breathing/vent holes.
  • Core Specs: Standard 3-inch inner paper/plastic core to fit regular machinery mandrels.

2. Primary Uses & Application Scenarios

  • E-Commerce & Logistics Fulfillment: Rapid packaging for small garments, socks, and accessories.
  • Hardware & Fasteners: High-speed sorting and bagging of screws, bolts, hinges, and plastic fittings.
  • Electronics & Components: Packaging for cables, connectors, switches, and small modules.
  • Medical & Industrial Parts: Automated bagging for non-sterile components, gaskets, and spare kits.

3. Key Product Considerations & Testing Standards

  • Perforation Line Tension: Perforations are calibrated to tear cleanly during machine indexing without premature separation.
  • Side Seal Integrity: Reinforced side seals withstand high-speed mechanical opening and product dropping impact.
  • Film Opening & Antistat Performance: Anti-block formulations help ensure smooth air-blown opening during automatic cycle steps.
  • Recommended Thickness: 40–50 Microns for light items; 60–80 Microns for hardware or items with dense weight.

4. FAQ

Q1: How can I verify if these auto bags are compatible with my packaging machine?

A: Provide your machine brand, model, roll width limits, and core size. Sample testing rolls are recommended prior to order release.

Q2: What vector details are needed for custom artwork layout on roll bags?

A: AI, PDF, or EPS vector files are required. Printing pitch distance and repeat length must align with machine sensor marks.

Q3: What printing technology is used for heavy-volume continuous roll printing?

A: Rotogravure or flexographic printing is applied depending on order volume and graphic color resolution requirements.

Q4: What is the packaging method to prevent roll deformation during transport?

A: Rolls are wrapped in protective film, suspended on core plugs, and boxed into heavy-duty corrugated master cartons.
