The Evolution of Custom Printed Woven Bags in Global Packaging
Custom Printed Woven Bags have transformed from basic packaging solutions into powerful branding and sustainability tools. These bags, also known as Poly Fabric Bags, combine durable woven polypropylene (WPP) substrates with advanced printing technologies to deliver visually striking, high-performance packaging. As global markets demand sharper graphics, eco-friendly materials, and regulatory compliance, manufacturers like VidePak are leading innovations that redefine packaging standards.
Global Standards and Material Selection: A Technical Deep Dive
Selecting the right polypropylene (PP) resin grade requires aligning with regional standards and performance needs:

- Additives: 0.3% UV-531 (anti-UV), 0.2% Irganox 1010 (antioxidant)
- Applications: Agricultural packaging needing 6-month outdoor durability
2. JIS Standards (Japan)
- Grade: Impact Copolymer PP (JIS K6922)
- Izod Impact: 12 kJ/m² (-20°C)
- Additives: 0.5% calcium stearate (slip agent)
- Applications: Retail packaging requiring tear resistance
3. EN Standards (Europe)
- Grade: Random Copolymer PP (EN ISO 1873-2)
- Tensile Strength: 35 MPa (MD), 30 MPa (TD)
- Additives: 1.5% TiO₂ (opacity agent)

Material Innovation:
VidePak’s proprietary PP compound (VP-7800 series) blends 25% recycled content while retaining 92% of virgin resin performance in dart impact tests (ASTM D1709).
Printing Technologies: Precision and Durability
VidePak uses rotogravure and flexographic printing systems to achieve:
- Resolution: 175 lines/inch (rotogravure) vs. 133 lines/inch (flexo)
- Ink Adhesion: 4.8 N/15mm (ISO 2409) on BOPP-laminated surfaces
- Colorfastness: Grade 5 (AATCC 16E) after 800 hours QUV exposure
Case Study:
A European coffee brand achieved 98.7% color match accuracy (ΔE ≤1.2) using VidePak’s 10-color rotogravure line, reducing reprint rates by 31%.
