MDO Unidirectional Stretch Film Production Line PET PP PE PA Cast Film Production Line

Description :

　　Stretch film has evolved from single-layer to two-layer, three-layer production. Nowadays, stretch film produced by casting method is the main method, while early stretch film was mostly blown film. This is because the production of casting line has the advantages of uniform thickness and high transparency, which can meet the requirements of high magnification pre stretching. The stretch film produced by the casting method has high transparency, elongation, puncture strength, and tear strength.

　　Stretch film has a wide range of applications and is widely used in the integrated packaging of various products such as hardware, minerals, chemicals, pharmaceuticals, food, machinery, etc. Cast film has superior heat sealing performance and excellent transparency, and is one of the main packaging composite substrates used in the production of high-temperature cooking film, vacuum aluminum plating film, etc.

　　Jinwei Machinery MDO Unidirectional Stretch Film Production Line PET PP PE PA Cast Film Production Line: Among them, there are two types of longitudinal stretching machines: vertical and horizontal. The horizontal structure is easy to expand and has convenient membrane introduction, suitable for pilot and small-scale production. The vertical structure has a small footprint and is suitable for laboratory use.

　　[Equipment Features]

　　1. The preheating roller, stretching roller, annealing roller, and cooling roller are all driven by servo motors, with high speed control accuracy

　　2. The spacing between the stretching rollers can be adjusted to achieve "zero spacing" stretching and reduce necking effect

　　3. Single point and double point stretching are optional, and the stretching ratio can be continuously adjusted

　　4. Oil/electric heating options: Oil heating has a uniform temperature, while electric heating can achieve high process temperatures

　　5. The side panel is equipped with a maze style membrane guiding groove, which is convenient for manual membrane guiding

　　6. Aluminum alloy integral side panel frame, light weight, high strength, corrosion resistance, long service life

　　7. High performance PLC with 12 inch touch screen, high control accuracy and easy operation

　　The MDO two-point stretching process can significantly improve the performance of thin films, such as their impermeability, stiffness, flatness, tensile strength, and porosity. In addition, MDO film has high flatness, fast operation speed during subsequent processing, and high yield. Online casting and stretching equipment, mainly used for manufacturing high-performance functional films
