The calculation of the weight and length of PE winding film are different. It is thought that the weight of each roll is different due to its different length, and the calculation formula is the same. However, for the conversion of some units, we need to pay special attention to the error of sometimes dividing by one decimal point, and the result will be much worse　

Hangzhou plastic packaging company tells you the characteristics and application of PE winding film　

POF heat shrinkable film characteristics: 1. Tensile strength and impact resistance; 2. Excellent transparency and rich luster; 3. High shrinkage; 4. Hot butt joint, tight without carbon trace; 5. Low temperature resistance　

he heat shrinkable film is designed based on the tensile orientation principle of highly oriented molecular chain and formed by rapid cooling. Generally speaking, the heat shrinkable film is POF, or polyolefin shrink film 　

The heat shrinkable film system is designed based on the tensile orientation principle of polymer molecular chain and formed by rapid cooling. Its physical principle is: when the polymer is in a high elastic state, its tensile orientation, and then quench the polymer to the glass transition temperature...　

PE heat shrinkable film is suitable for the whole package of wine, cans, mineral water, various beverages and other products. The product has good flexibility, strong impact and tear resistance, not easy to damage, not afraid of moisture and high shrinkage.
