Working Principle of MDO Technology
1. Heating: The base film is passed through controlled heating zones to reach the optimal temperature for stretching.
2. Stretching: The film is stretched in the machine direction using high-precision rollers, aligning the polymer molecules for improved properties.
3. Annealing: Post-stretching, the film is stabilized through controlled cooling and annealing to prevent shrinkage and maintain dimensional stability.
4. Winding: The final product is wound into rolls for further processing or direct use.
1. Extrusion Unit: Produces the base film, often in multi-layer configurations (e.g., PE, PP, PET).
2. Pre-Heating Section: Gradually heats the film for uniform stretching.
3. Stretching Section: Adjustable rollers allow precise control of stretching ratios.
4. Cooling and Annealing Unit: Ensures film stability and quality.
5. Control System: Equipped with PLC or SCADA systems for automation, real-time monitoring, and recipe storage.
6. Edge Trimming and Recycling: Minimizes waste by reprocessing trimmed edges.
1. Flexible Packaging: Food packaging, pharmaceutical wraps, and consumer goods.
2. Label Films: Shrink labels, adhesive labels, and thermal transfer printing films.
3. Industrial Uses: Protective films, lamination substrates, and agricultural films.
4. Optical Films: Display screens, touch panels, and lighting covers.
Customization Options
The production line can be tailored to meet specific industry requirements, including:
Stretching Ratios: Adjustable from 2:1 to 10:1, depending on the film properties needed.
Film Thickness Range: From ultra-thin films (8 microns) to thicker films (100 microns).
Layer Configuration: Single-layer or multi-layer co-extrusion for specialized applications.
Additive Integration: Incorporates anti-static, anti-fog, or UV-blocking additives.
Market Trends and Advantages
- Growing demand for lightweight and sustainable packaging has accelerated the adoption of MDO technology.
- Films produced on MDO lines are increasingly replacing multi-material films due to their recyclability and cost-effectiveness.
- Advanced MDO production lines can process bio-based and compostable polymers, meeting the needs of eco-conscious markets.
With its ability to produce high-quality films at lower costs, the uni-axial stretch film production line is a game-changing solution for manufacturers seeking innovation, efficiency, and sustainability.
