Multiwall Laminated Woven Bags: Evolution and Impact


“Why have multiwall laminated woven bags become the packaging solution of choice for industries ranging from petrochemicals to agriculture?”
At a recent global logistics expo, VidePak’s CEO Ray Chiang fielded this question with precision: “The answer lies in their unmatched adaptability—engineered through 4 decades of material science advancements, precision manufacturing, and market-specific customization. Our clients report 40% fewer transit damages and 22% lower per-unit costs compared to single-layer alternatives.”

Since their commercial debut in the 1980s, multiwall laminated woven bags have evolved from basic grain carriers to high-tech protective systems. VidePak, with its 16 extrusion lines and ISO 22000-certified food-grade production zones, stands at the forefront of this revolution. Let’s unpack how these bags are reshaping global logistics.


1. Market-Driven Evolution: From Uniformity to Hyper-Customization

1.1 Regional Demand Analysis

VidePak’s 2024 market study reveals stark regional preferences:

MarketKey RequirementsVidePak Solution
EU ChemicalsREACH compliance, 8-color CMYK printingPE/EVOH 5-layer lamination + RFID tracking
US AgricultureUSDA/FDA certification, UV stabilization120gsm BOPP lamination + 6% TiO2 additive
SE Asia Construction2,000kg stacking strength, monsoon resistance3-ply kraft/PP hybrid + silicone anti-slip coating

Case Study: A German polymer manufacturer reduced moisture-related rejects by 91% after switching to VidePak’s aluminum oxide-coated food-grade laminated bags.

1.2 The Certification Edge

VidePak holds 23 global certifications, including:

  • Food Safety: FDA 21 CFR, EU 10/2011
  • Hazardous Materials: UN 6.1, IMDG Code
  • Sustainability: Oeko-Tex 100, GRS 4.0

2. Engineering Breakthroughs: The Starlinger Advantage

2.1 Layer Architecture Innovation

Modern multiwall bags combine up to 7 functional layers:

  1. Outer Woven PP (120-150gsm): UV-stabilized, 12×12 weave density
  2. Adhesive Lamination (18-25gsm): Polyurethane-based, 98% bond strength
  3. Barrier Film (40-100μm): EVOH for O₂ blocking, AlOx for moisture
  4. Inner Liner (HDPE/LDPE): FDA-compliant, anti-static treatments

VidePak’s 30 lamination machines achieve 0.02mm layer alignment precision—surpassing ASTM D882 standards by 60%.
