The reasonable and scientific control of the temperature of the plastic film blower is more helpful to better blow the film. The plastic film can achieve the expected quality target. The membrane made by the plastic film machine is good due to its good blocking, preserving freshness, hygroscopic anti -frost, and freezing frost. , Oxygen, oil -resistant, can be widely used in severity packaging, such as various fresh fruits, meat foods, pickles, fresh milk, liquid drinks, pharmaceutical supplies and other fields. The temperature of the film requires a suitable temperature. So how will this temperature be controlled?
According to the melting theory of plastic, the extrusion screw of the extrusion film is divided into three segments: the feed section, the melting section, and the average section. At the end of the feeding section, at the beginning of the melting section, according to the theory of melting, its temperature should be a sticky temperature. The temperature of various film blowing resin sticking temperatures are PP: 164-175 degrees Celsius, PE: 105-135 degrees Celsius, PA: 195-210 degrees Celsius, the environment determines product quality.
Under the new development situation, the original high -energy and high -pollution production model has been difficult to maintain. If the film blower market cannot be optimized with the development of the market and innovative development, then it can only be being able to be subject to The market is eliminated, the PE film is widely used in daily life, and the development of the PE film machine also presents a good form. Under the new situation, green energy saving and environmental protection have become a new development direction. It is also continuously carried out. The PE foam film produced by PE as the material is an innovative product under the new situation.
