VidePak’s PP woven fabric bags exemplify the synergy of cutting-edge automation and precision engineering, achieving production speeds of 200+ bags per minute, tensile strengths exceeding 50 N/cm², and defect rates below 0.1%—all powered by Austrian Starlinger and German W&H machinery, ensuring global clients receive packaging solutions that redefine durability, customization, and efficiency.
Introduction: A Legacy of Innovation
Since 2008, VidePak has emerged as a global leader in woven packaging, driven by a 30+ year veteran team and a workforce of 568 professionals. With annual sales surpassing $80 million and a footprint across 70+ countries, our success hinges on mastering every stage of PP woven bag production—from extrusion to printing—while integrating world-class automation. This article dissects our manufacturing process, highlights quality control protocols, and demonstrates how partnerships with Starlinger and W&H enable unmatched scalability for industries ranging from agriculture to construction.
Section 1: The Manufacturing Process – Precision at Every Stage
1.1 Extrusion: Crafting the Foundation
The journey begins with extrusion, where virgin polypropylene pellets are melted at 220–260°C and transformed into thin, uniform films. VidePak’s 16 extrusion lines, equipped with W&H’s EcoXtreme technology, ensure precise temperature control and output consistency. Key metrics include:
- Film Thickness: 18–200 microns (adjustable per application).
- Output Speed: 150–200 kg/hour per line.
Quality Control: Infrared sensors monitor film thickness in real time, with deviations auto-corrected to ±2 microns.
1.2 Tape Drawing: Refining Strength and Flexibility
The extruded film is slit into tapes (1.8–3.0mm width) and stretched to align polymer chains, enhancing tensile strength. VidePak’s Starlinger STeP system achieves:
- Tensile Strength: 45–60 N/cm².
- Elongation at Break: <15% for rigidity.
Quality Control: Laser micrometers verify tape width, rejecting batches with >0.1mm variance.
1.3 Weaving: Building the Fabric Matrix
Using 100+ circular looms, tapes are interwoven into fabric rolls. Starlinger’s CX6+ series looms operate at 220 rpm, producing fabrics with densities of 10×10 to 14×14 strands/inch². Applications include:
- Heavy-Duty Sacks: 14×14 weave for 50kg cement loads.
- Food-Grade Bags: 12×12 weave with anti-static coatings.
Quality Control: Automated cameras detect broken threads, triggering loom pauses within 0.5 seconds.
1.4 Lamination and Coating: Enhancing Functionality
Fabric rolls are laminated with BOPP, PE, or kraft paper using 30 lamination machines. W&H’s Novotec systems apply coatings at 18–75 microns, achieving:
- Moisture Resistance: <0.5% permeability (tested per ASTM E96).
- UV Stability: 1,200+ hours without degradation (ASTM G154).
Quality Control: Cross-directional thickness scanners ensure ±1.5% coating uniformity.
1.5 Printing: Branding with Precision
VidePak’s 12-color flexographic printers deliver Pantone®-matched designs at 0.1mm registration accuracy. Features include:
- Print Speed: 180–200 bags/minute.
- Ink Adhesion: >4.5/5 on ASTM D3359 cross-hatch tests.
Quality Control: AI-driven optical inspection rejects bags with color deviations (ΔE >1.5).
1.6 Bag Conversion: Final Assembly
Automated sewing and heat-sealing machines produce finished bags with:
- Seam Strength: >80% of base fabric strength (ISO 13934-1).
- Closure Types: Sewn, heat-sealed, or valve-based.
Quality Control: Load testing simulates 2x rated capacity to validate durability.
Section 2: Quality Assurance – A Data-Driven Approach
VidePak’s ISO 9001-certified system ensures excellence through:
- Raw Material Testing: PP resin purity verified via FTIR spectroscopy.
- In-Process Monitoring: IoT sensors track 200+ parameters per production line.
- Final Inspection: 100% bag抽样 tested for leaks (pressure decay method) and print integrity.
Case Study: A fertilizer client required 500,000 UV-resistant bags. VidePak’s Starlinger-equipped lines delivered the order in 18 days, with 0 defects reported over 12 months of use.
