Foshan City's high-quality four-side sealing bag plastic products Stretch stretch film is a kind of packaging products used to bundle goods. Its uniqueness depends on its ability to use mechanical equipment, drawing equipment or manual production to cause deformation and geostress . But do you know how to manipulate the viscosity of the adhesive layer of the four-side sealing bag?
There are many raw materials for the four-side sealing bag in Foshan City. The key is the main purpose of the product. Therefore, to stretch the viscosity of the stretch film, you can work hard on the raw materials. C6 and C8 raw materials, which are not necessarily used for stretch film, are often used because of their easy production and processing. There is also temperature that will harm the viscosity of stretch film. Generally, people will put the product in a natural environment of 15 to 25 degrees. If the average temperature exceeds 30 degrees, the viscosity will immediately expand; if it is less than At fifteen degrees, the viscosity will be worse. Because the stretch wrap film also contains high-pressure polyethylene, we can adjust the amount of high-pressure polyethylene in the adhesive layer to achieve the required viscosity. Because the content of stretch wrap film is relatively narrow, and the scope of production and processing of high-quality four-side sealing bags in Foshan City is also relatively narrow, generally if 5% of high-pressure polyethylene is added, the effect of reducing the viscosity of the solution can be achieved. The flatness of the stretch film will also gradually increase the flatness of the plastic film.
The definition and application of high-quality four-side sealing bag stretch stretch film in Foshan City originated from 1972, and the development trend is to include three materials: PVC stretch stretch film, PE stretch stretch film and PP stretch stretch film. bag. PVC stretch stretch film is a substitute for stretch stretch film. At that time, the British UION company maintained the modern mass production of polyethylene, which enabled polyethylene to achieve a disruptive and rapid development trend in various fields. PVC polyethylene has resilience and wear resistance. , Anti-penetration, anti-aging and other characteristics, promote the rapid development of PVC materials in the film industry level, the huge area will facilitate everyone's food, clothing, housing and transportation. However, with the improvement of people's physical and mental health and environmental protection awareness, polyethylene and other insoluble stretch stretch films have just begun to be eliminated, but PVC is an indispensable raw material. Nowadays, high-quality four-sided sealing bags are mainly used in wood. , Steel, machinery and equipment and other manufacturing industries. There are PVC materials that cannot be used. In 1996, when opened up and down, there was an odorless and environmentally friendly PE stretch wrap film-PE stretch wrap film. This is also the main stretch wrap film. PE stretch wrap film has the physical characteristics of continuous PVC It also has the characteristics of thermosetting plastic and compatibility. The key is that PE stretch stretch film is not easy to chop and heat resistance, which promotes the development trend of PE stretch stretch film into nowadays stretch stretch film, deriving fresh-keeping bags, stretch stretch film, and other types.
