For businesses prioritizing visibility, durability, and branding flexibility in packaging, one critical question arises: How do Transparent Woven Bags ensure product integrity while offering unmatched design versatility? The answer lies in VidePak’s rigorous quality protocols, advanced Starlinger weaving systems, and proprietary printing technologies that deliver tear-resistant, UV-stable, and visually striking packaging solutions. With an annual production capacity of 100 million units and clients ranging from European fertilizer distributors to North American pet food brands, VidePak’s Transparent Woven Bags combine functional excellence with aesthetic adaptability, reducing supply chain losses by up to 25% for clients like a Brazilian coffee exporter.
1. Material Science and Quality Assurance
1.1 Virgin PP/PE Granules: The Foundation of Durability
VidePak uses 100% virgin polypropylene (PP) and polyethylene (PE) resins to manufacture transparent woven fabrics, avoiding recycled materials that compromise clarity and tensile strength. Key specifications include:
- Melt Flow Index (MFI): 2.5–4.0 g/10 min (ASTM D1238), ensuring uniform extrusion.
- Fabric Density: 10×10 to 14×14 threads per inch, balancing transparency (85–90% light transmission) and puncture resistance.
- Thickness Tolerance: +5% to +8% against industry-standard ±10%, minimizing “weak spots” that cause bursting.
Case Study: A Vietnamese shrimp feed supplier eliminated 98% of “炸包” incidents (bursting during transport) by switching to VidePak’s 12×14 weave bags with 0.18 mm thickness (+7% tolerance).
1.2 Anti-Static and UV Stabilization
For chemical or agricultural products prone to static buildup, VidePak integrates:
- Carbon-black masterbatches: Reducing surface resistivity to 10⁶–10⁸ Ω.
- UV inhibitors: Extending outdoor shelf life to 18+ months (per ASTM D4355).
2. Starlinger Technology: Precision Weaving at Scale
2.1 Seamless Tubular Weaving Process
VidePak’s 100+ Starlinger STeX circular looms produce continuous tubular fabrics with:
- Thread Alignment Accuracy: <1° deviation, preventing skewed weaves.
- Production Speed: 200–240 rpm, yielding 12,000 bags/hour.
- Energy Efficiency: 25% lower power consumption vs. conventional looms.
2.2 Extrusion and Lamination Systems
- 16 Extrusion Lines: Layer PP/PE films (0.015–0.04 mm) onto woven substrates, enhancing moisture barrier properties (WVTR ≤5 g/m²/day, ASTM E96).
- 30 Lamination Machines: Apply BOPP or PE coatings without compromising transparency.
3. Custom Printing: Fusing Aesthetics with Function
3.1 High-Definition Flexographic Printing
VidePak’s 30+ printing units achieve:
- Resolution: 175 lines per inch (LPI), reproducing gradients and microtext.
- Color Fastness: ΔE ≤1.5 after 500 hours of xenon-arc exposure (ISO 105-B02).
- Ink Adhesion: 4.5/5 score on cross-cut tests (ASTM D3359).
Example: A Spanish olive grower boosted brand recognition by 40% using VidePak’s transparent bags with gold metallic inks visible under retail lighting.
3.2 Anti-Counterfeiting Features
- Holographic Foils: Integrated during lamination.
- Invisible UV Markers: Detectable under 365 nm light.

4.2 FAQs
Q1: How do Transparent Woven Bags prevent condensation in humid climates?
A: Our PE-coated bags reduce water vapor transmission to ≤3 g/m²/day, as used by a Malaysian palm sugar producer to maintain product dryness at 85% RH.
Q2: Can these bags withstand freezer temperatures (–20°C)?
A: Yes. PP/PE blends retain flexibility down to –30°C (Izod impact strength ≥60 J/m, ASTM D256).
Q3: Are VidePak’s inks food-safe?
A: All inks comply with EU No 10/2011 and FDA 21 CFR for indirect food contact.
