MDO Stretch Roller BOPA Stretch Roller BOPP Stretch Roller For Bi-Oriented PP And Pet Film
Product Description
MDO (Machine Direction Orientation) stretching Rollers are essential components in the production of bi-oriented stretch films, including BOPP (Biaxially Oriented Polypropylene), BOPET, BOPA films. These rollers play a crucial role in the stretching process.
Product Feature
1. Design: MDO stretching rollers are typically designed with multiple rollers arranged in a specific configuration to achieve the desired stretching ratio and film properties.
2. Roller Adjustability: MDO stretching rollers can often be adjusted to accommodate different film thicknesses and stretching ratios, providing flexibility in the production process.
3. Cooling Capability: MDO stretching rollers may also have cooling mechanisms to rapidly cool down the film after stretching, ensuring proper solidification and stabilization.
4. Roller Surface: The surface of MDO stretching rollers is carefully engineered to provide the necessary grip and traction on the film during the stretching process.
5. Heating Capability: Some MDO stretching rollers are equipped with heating elements to raise the temperature of the film, allowing for better stretching and orientation.
6. Improved Film Properties: The use of MDO stretching rollers helps enhance the mechanical properties of bi-oriented stretch films, including tensile strength, stiffness, shrink properties, gloss, and transparency.
