Plastic film blowing machine knowledge so much you know

  Plastic film blowing machine boot operation is required to inspect the various power wiring is disconnected, leakage; instrument checks whether the damage is not normal. Before starting to ensure the safety of the various parts of the normal, so as not to affect the production and cause accidents. The production of plastic film blowing machine is the film, these films are widely used according to different materials and characteristics with multiple fields. Suitable for all kinds of high grade film packaging, plastic bag with film, protective film and so on.

  This film due to its good barrier properties, anti wet, anti frost, oxygen, fresh, oil, can be widely used in light and heavy packaging. Such as a variety of fresh fruits, meat dish, liquid beverages, pickles, fresh milk and other medical supplies. Time to develop a good temperature control inspection, heating appliances intact, pay attention to the timely adjustment of the heating temperature in the indicators within the scope of good habits; if there is an exception to be resolved in a timely manner.

  Low density polyethylene (LDPE) is a kind of plastic material, which is suitable for thermoplastic forming process, and the forming process is good. LDPE is mainly used for film products, also used in injection molding products, medical equipment, medicine and food packaging materials, blow molding hollow products, etc.. Linear low density polyethylene, the structure is different from the general low density polyethylene, because there is no long chain.

  The linearity of LLDPE depends on the different production processes of LLDPE and LDPE. LLDPE usually in lower temperature and pressure, by the ethylene and advanced a olefins such as the polymerization of maleic or. The LLDPE polymer produced by the copolymerization process has a narrower molecular weight distribution than that of the general LDPE, and has a linear structure with different rheological properties.

  High density polyethylene (Density Polyethylene High, referred to as "HDPE"), is a high degree of crystallinity, non polarity thermoplastic resin. The appearance of the original HDPE is milky white, with a certain degree of semi transparent shape in the thin section. PE has excellent chemical resistance properties for most domestic and industrial. Some kinds of chemicals will produce chemical corrosion, such as corrosive oxidant (nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is not hygroscopic and has good waterproof steam, can be used for packaging purposes. HDPE has good electrical properties, especially the insulation dielectric strength is high, so it is suitable for wire and cable.

  Medium to high molecular weight grades has excellent impact resistance, even at room temperature under low temperature so -40F. According to the forecast, to 2005 China plastic packaging materials in the field of market demand will reach 550 million tons, annual demand growth rate of 1O%, in the plastic products industry growth the fastest is sunrise industry with broad prospects for development.

  Film is one of the largest amount of plastic packaging materials, due to its non-toxic, light quality, packaging beautiful and low cost characteristics. Therefore, the application continues to expand, almost penetrated into all aspects of industrial and agricultural products and daily necessities, plastic packaging film industry investment is growing rapidly. With the development of economy, the rapid development of plastic flexible packaging, plastic flexible packaging has become the main way of food packaging, China's flexible packaging industry has become its own basic industrial chain. Film blowing machine is the industry's most important one of the mechanical equipment, when the flexible packaging of food packaging materials gradually become the protagonist.

  The quality of Dalian film blowing machine quality and blowing technology determines the film forming. So a good performance of the film blowing machine in the film production process showed good ability to adapt to the market, improve production efficiency at the same time, provide convenience for the people, and promote the harmonious development of the society. Food packaging is widely used film field, film blowing machine, blowing high-end film can be used as commodity packaging and promotion, to enhance the commercial value. In order to meet the market on a variety of products packaging, film blowing machine manufacturing industry to produce new film blowing machine sheet film blowing machine, PE film blowing machine, multi-layer co extrusion film blowing machine, film blowing machine, heat shrinkable film blowing machine and so on.
