BOPP Laminated Valve Woven Bags: Engineering Sustainable Packaging Excellence

How Biaxially-Oriented Polypropylene Redefined Industrial Valve Bag Performance

The evolution of packaging technology has given BOPP Laminated Valve Woven Bags a pivotal role in modern bulk handling. This hybrid design merges the tensile strength of woven polypropylene with the barrier properties of biaxially-oriented film, creating solutions that balance operational efficiency with planetary health. At VidePak, we’ve refined this synergy through 17 years of material science innovation and global market deployment.

• Dust Mitigation: 99.7% particle capture (OSHA PEL compliant)
• Cycle Endurance: 10,000+ fill/seal operations (PMMI certification)

2.3 Printing Excellence

• Resolution: 1200 DPI rotogravure with 92% Pantone® matching
• Abrasion Resistance: 500 Taber cycles at 1,000g load (ASTM D4060)
• Color Fastness: 7/8 rating (AATCC 16.3)

Capacity: 16 extrusion lines producing 1.2M bags/day with <0.3% defect rate.

3. Application Innovation: From Chemicals to Consumer Goods

Different industries demand tailored solutions. VidePak’s process addresses six critical parameters:

1. Chemical Sector:
   • Corrosion-resistant EP liners for pH 2-12 contents
   • UN-certified hazardous material packaging (4G/Y1.4 certification)
