China is a big country in the world of packaging manufacturing and consumption . The proportion of plastic packaging in the total output value of the packaging industry has exceeded 30%. It has become a new force in the packaging industry and plays an irreplaceable role in various fields of medicine, beverage, daily necessities and industrial and agricultural production. At present, plastic products produced in China are mainly made of plastic film (including agricultural film), plastic wire and woven products, plastic pipes and daily-use plastic products. If it is divided by application, packaging supplies are one of Zui's main plastic applications. PE, PP and PET are three kinds of plastic packaging materials commonly used by Zui . Among the PE plastic packaging industry, non-polar and polar ethylene copolymers and metallocene ethylene are the two hot spots in the development of European and American countries. Ethylene copolymers can improve the stretching and coextrusion properties of plastic films, increase transparency, enhance stability, and improve molecular weight distribution and extrusion rheological properties. The film strapping machine produced by our company uses the plastic packaging technology reasonably. It changes the traditional product packaging and saves the middle box packaging, which greatly reduces the cost and reduces the waste of materials. The film strapping machine itself is faster, which greatly increases the production efficiency of the enterprise; Fei County Mingtao Electronic Co.,Ltd , https://www.yourbeautyassistant.com
