The production of Laminated Woven Bags has undergone significant advancements, largely driven by the adoption of the multi-layered co-extrusion blown film process. This cutting-edge technique, combined with high-precision equipment from Austrian Starlinger and German W&H, has revolutionized the industry, providing unmatched durability, flexibility, and efficiency in packaging solutions. Let us explore how these advancements have reshaped the landscape of Laminated Woven sacks and BOPP Woven Bags while highlighting the critical role of the drawing process in improving their performance.
The Multi-Layered Co-Extrusion Blown Film Process
The multi-layered co-extrusion blown film process is at the core of manufacturing high-quality Laminated Woven Bags. This process involves extruding multiple layers of molten plastic through a die, which are then inflated to form a thin film. The layers are fused to achieve optimal strength, moisture resistance, and aesthetic appeal. The benefits of this process include:
- Enhanced Durability: Multi-layered structures improve resistance to tearing and puncturing.
- Moisture Resistance: Laminations provide an effective barrier against moisture, preserving product integrity.
- Customizability: Multi-layer films support vivid and multi-color printing, meeting diverse branding needs.
- Eco-Friendly Solutions: Recyclable materials can be incorporated, contributing to sustainability.
This technology is particularly impactful in creating multi-wall woven bags and Laminated PP bags, offering exceptional protection for products ranging from chemicals to agricultural goods.

The Role of Drawing in Bag Durability and Flexibility
Drawing, or stretching, is a critical step in the production of woven fabrics, directly influencing the durability and flexibility of Laminated PP bags. The process involves the following:
- Orientation of Polymer Chains: During drawing, polymer molecules are aligned, significantly enhancing tensile strength.
- Controlled Stretching: Precise control over the stretch ratio ensures uniformity and prevents weak points.
- Customization: Adjusting drawing parameters enables the production of fabrics with tailored flexibility and rigidity.
These improvements are particularly vital for applications such as multi-wall woven bags, where bags must endure rough handling and heavy loads without compromising on flexibility.
Table: Comparative Properties of Woven Bags with Different Drawing Ratios
| Parameter | Low Stretch Ratio | Medium Stretch Ratio | High Stretch Ratio |
|---|---|---|---|
| Tensile Strength (MPa) | 25 | 35 | 45 |
| Elongation at Break (%) | 40 | 25 | 15 |
| Flexibility | High | Moderate | Low |
| Suitable Applications | Lightweight Goods | General Packaging | Heavy-Duty Goods |
The enhanced durability and flexibility achieved through meticulous drawing are particularly significant for the production of Laminated PP bags and BOPP Woven Bags, ensuring they meet diverse market demands.
