H1: Introduction
“In the packaging industry, the shift toward lightweight solutions isn’t just a trend—it’s a necessity. By rigorously testing PP/PE raw materials and leveraging advanced weaving technologies, VidePak’s lightweight woven bags deliver unmatched durability, cost efficiency, and environmental benefits, redefining logistics and storage for global industries.” — Ray, CEO of VidePak.
The global demand for lightweight woven bags is projected to grow at a CAGR of 4.8% through 2033, driven by their versatility, recyclability, and logistical efficiency. VidePak, a leader in woven bag manufacturing since 2008, combines Austrian Starlinger machinery with stringent quality control protocols to produce bags that excel in both performance and sustainability. This report explores how material testing and innovative designs position VidePak’s lightweight woven bags as indispensable tools for modern supply chains, supported by technical data, case studies, and market insights.

H3: PP Granule Testing for Woven Bag Production
Polypropylene (PP) granules undergo rigorous testing to ensure optimal performance in high-speed weaving processes. VidePak adheres to GB/T 8946-2013 and ASTM D1238 standards, focusing on:
- Basic Physical Properties:
- Melt Flow Index (MFI): Measured at 230°C/2.16kg, VidePak’s PP granules achieve an MFI of 8–12 g/10min, ensuring uniform extrusion and weaving efficiency.
- Density: Controlled within 0.905–0.915 g/cm³ using ASTM D792 methods, balancing rigidity and flexibility.
- Mechanical Performance:
- Tensile Strength: Starlinger’s AD-STM looms produce PP tapes with tensile strength exceeding 45 MPa (vs. industry average of 35–40 MPa), critical for heavy-load applications like cement storage.
- Elongation at Break: Maintained at 15–20% to prevent brittleness during high-speed filling.
- Thermal Stability:
- Heat Distortion Temperature (HDT): Tested at 1.8 MPa, VidePak’s PP withstands 110–120°C, ensuring integrity in tropical climates.
- Crystallization Temperature: Monitored via DSC to ensure consistent fiber alignment during extrusion.
- Visual and Contaminant Checks:
- Color Uniformity: Rejects batches with >5% variance in pellet color (per GB 11115-89).
- Impurity Screening: Metal detectors eliminate particles >0.5mm, reducing loom jams by 30%.
H3: PE Granule Testing for Inner Liners
Polyethylene (PE) liners require additional tests to ensure flexibility and impact resistance:
- Film Impact Strength: Dart drop tests (ASTM D1709) confirm PE liners achieve 150–200 kJ/m², preventing punctures during rough handling.
- Seal Integrity: Heat-sealed seams withstand 15 N/mm peel force (ISO 527-3), crucial for powdered materials like flour.
Table 1: Key Material Testing Parameters
| Parameter | PP (VidePak) | PE (VidePak) | Industry Standard |
|---|---|---|---|
| Melt Flow Index | 8–12 g/10min | 0.5–2 g/10min | 5–15 g/10min (PP) |
| Tensile Strength | ≥45 MPa | ≥25 MPa | 35–40 MPa (PP) |
| Dart Impact Strength | N/A | 150–200 kJ/m² | 100–150 kJ/m² (PE) |
| HDT (1.8 MPa) | 110–120°C | 75–85°C | 90–110°C (PP) |
