What are the procedures for making stretch film?
Stretch film is mainly used for the transportation of various products. In the transportation process, it can play a good role in stabilizing, covering and protecting the products. In addition, the stretch film also has a high puncture resistance, good shrinkage and a certain shrinkage stress. So how does a stretch film get made? How many processes does the production of stretch film need to go through?
What is the production process of stretch film?
1. Install the lower film on the reel, clamp the edge of the lower film on the chain, and drive the lower film forward through the operation of the chain. In order to ensure the stability of the tension of the lower film during the operation, tension adjustment device is installed at the unwinding place;
2. When the film runs under the stretch forming plate, the lower film is pre-heated by the heating plate and then stretched; Then, the upper film is installed on the reel, through the tension roller, cursor tracking device and guide roller, in the heat sealing plate and the lower film confluent heat sealing together, in the process of operation to ensure the stability of the tension of the upper film, also installed in the unwinding tension adjustment device;
3. After the upper and lower membranes are joined, the heat sealing device first seals the upper and lower membranes, and then pumps the upper and lower air into a vacuum state. Then the upper and lower membranes are heated by the heat sealing plate, so that the upper and lower membranes are heat sealed together under the action of pressure.
4 According to different requirements, the use of printing date is different, so the location of the printing date device is different, the use of ribbon printing in front of the hot seal plate, the use of ink printing after the hot seal plate;
5. The whole stretch film with products needs to be cut in two directions: transverse and longitudinal, so that multiple products after packaging can be cut into a single product;
6. The packaged products must be sterilized in the sterilizing pot.
What causes the forming effect of stretch film to be bad?
With the application of stretch film more and more widely, we can see the production of stretch film manufacturers are more and more, in many production of stretch film manufacturers, there is no lack of some small manufacturers Bingzhe the purpose of making money quickly to produce some substandard stretch film, so many people have found that they buy these manufacturers of stretch film products molding effect is not ideal, Even very affect our use, so in the end what is the cause of the tensile film molding effect is not good?
Stretch film manufacturers explain the five advantages of stretch film in practical application
Stretch film is suitable for food and medicine packaging materials, only do food utensils, medical equipment, but also can do electronic industry insulation materials. Tensile film has the advantages of good flexibility, impact resistance, tear resistance, not easy to damage, not afraid of moisture, large scalability and so on. Next, "Wanshuangyu" stretch film manufacturer Xiaobian and you talk about the five advantages of stretch film in practical application:
How to reflect the effect of stretching film to save energy?
"Wanshuangyu" stretch film is first used the United States Exxon and the United States of America's high quality raw materials, using advanced production equipment, technology for large-scale production. High quality, high precision products directly serve the end consumer. In order to meet your higher needs, "Wanshuangyu" series of products are constantly to the functional, green, diversified direction of research and development. For the packaging of environmental protection, saving, high quality unremitting efforts. At present, Wanshuangyu series products - nano level ultra-thin winding film (thickness: 8--12um) has been successfully produced, which provides strong support for further reducing packaging costs and enhancing the competitiveness of enterprises.
