Why Choose PE Coated Valve Woven Bags Over BOPP Laminated Options?
Packaging plays a crucial role in product safety, branding, and operational efficiency. Among the various packaging solutions, PE Coated Valve Woven Bags have emerged as a preferred choice for industries ranging from agriculture to construction. Here’s a detailed comparison with Block BOPP Bags to highlight the strengths of PE-coated options.
| Feature | PE Coated Valve Woven Bags | Block BOPP Bags |
|---|---|---|
| Material Composition | Polypropylene (PP) fabric with polyethylene (PE) coating | PP fabric laminated with Biaxially Oriented Polypropylene (BOPP) |
| Moisture Resistance | Excellent, due to seamless PE coating | Good, but dependent on lamination quality |
| Printing Quality | Moderate, ideal for functional packaging | High-definition printing for branding |
| Cost | More cost-effective for bulk usage | Higher due to premium lamination processes |
| Application Flexibility | Better suited for valve-based filling systems | Ideal for consumer-facing products with high visual impact |
| Durability in Harsh Conditions | High, resistant to tearing and puncturing | Moderate, can delaminate under certain conditions |
Why PE Coated Valve Woven Bags Are the Smart Choice
- Enhanced Durability: The PE coating creates a watertight layer, making these bags ideal for moisture-sensitive materials like cement and fertilizers.
- Cost Efficiency: These bags offer excellent value for money, particularly in high-volume industrial use cases.
- Customizable Designs: From valve sizes to bag dimensions, PE Coated Valve Woven sacks can be tailored to specific customer needs, ensuring operational efficiency.
- Environmental Considerations: Unlike BOPP bags that often use additional laminates, PE Coated Valve Woven Bags reduce material wastage during production.

The Science Behind Valve PP Bags Manufacturing: Temperature and Stretch Ratio Control
In woven bag manufacturing, precise control over temperature and the stretch ratio during filament production is vital to ensure product quality. At VidePak, we employ the latest technology from Austria’s Starlinger and Germany’s W&H, which allows for superior control and efficiency.
Temperature Control in the Extrusion Process
- Melting Temperature: PP resins melt at approximately 160–170°C. Ensuring consistent melting is critical to prevent material degradation or uneven filament formation.
- Cooling Stage: Post-extrusion, the cooling stage solidifies the material. Rapid cooling can lead to brittleness, whereas slow cooling ensures a smoother surface and higher tensile strength.
- Heat Stabilization: Starlinger’s advanced systems allow for real-time monitoring, ensuring heat distribution uniformity across the extrusion line.
Stretch Ratio: The Secret to Superior Valve Woven Bags
The stretch ratio—how much the PP film is elongated during the drawing process—significantly influences the strength and flexibility of the final product.
- Low Stretch Ratio (5:1): Results in thicker filaments but reduced tensile strength. This is suitable for products requiring rigidity, such as certain Valve PP Bags.
- High Stretch Ratio (7:1 or above): Produces thinner, stronger filaments. This ratio is ideal for lightweight yet durable PE Coated Valve Woven sacks.
By integrating these parameters into our workflow, we achieve consistency and durability, making our products a benchmark in the industry.
Key Technical Features of Valve Woven Bags
| Parameter | Value | Effect |
|---|---|---|
| Tensile Strength | 300–350 N | High durability during transport |
| Moisture Barrier | <1 g/m²/day | Ideal for moisture-sensitive goods |
| Bag Weight | 50–150 g | Customizable based on application |
| Valve Diameter | 4–6 cm | Facilitates quick and efficient filling processes |
| UV Resistance | 200–400 hours | Extended shelf life in outdoor conditions |
