Polyolefin Shrink Film is a new type of environmentally friendly heat shrinkable packaging material that has emerged in recent years. It not only overcomes the shortcomings of poor heat resistance of PVC heat shrinkable film and strict storage conditions, but also avoids the poor tear resistance of PP heat shrinkable film, the weak performance of PE Shrink Film haze, and can have high transparency and resistance at the same time. Low temperature, high strength, and sturdy resistance. Shrink Film Manufacturer analysis that so far, there have been few accumulations of experience and technical research on POF production, and there are fewer relevant theoretical research reports. The introduction of production lines mostly stays at the general level of technology that can produce POF, lacks innovation, and often even causes significant losses due to incomprehension of the preparation process and storage mechanism.
