Even if there is only one day left in 2017, the shrink film can accompany you for one day

The shrink film is made into films of various colors. PVC shrink film is used in the sales and transportation process of various products. Its main function is to stabilize, cover and protect the product from scratches and scattering. The heat shrinkable film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinking process, the film cannot produce holes, and the temperature cannot be too high during shrinking, otherwise the surface temperature of the film will be too high and the film will break. The shrink film can be a multi-layer co-extruded polyolefin heat shrink film, which is mainly used for packaging products. Its characteristics are as follows: 1. First, the shrink film has better welding and sealing performance, and its strength is also high. Pack regular and irregular shaped products. 2. Secondly, the transparency of the shrink film is very high, and the gloss is also very good, so the use of shrink film packaging products can clearly display the appearance of the product, so that people can understand the product more clearly. 3. The shrink film has a large shrinkage rate and good flexibility, so it greatly meets the requirements of most customers and is favored by many customers. The recycled packaging materials are mainly plastic packaging, which can be made into recycled packaging containers after being treated by physical methods, and recycled packaging products can be made after treatment by chemical methods. Reused packaging materials are mainly used for packaging glass bottles such as beer and beverages. , Can be used repeatedly. However, these two methods have a flaw in their beauty. They only reduce environmental pollution, and in the end, they have to face the problem of environmental pollution. As the concept of low-carbon environmental protection has become the main theme of society, it is being practiced in many fields, as is the field of packaging materials. Heat-shrinkable film can be used for the transportation of a variety of products, which can protect the product. Because the shrinkage performance of heat-shrinkable film is relatively good, it has been loved by the majority of people. Today, heat-shrinkable film manufacturers bring you the inspection standards 1. When inspecting the heat shrinkable film, first look at the surface of the heat shrinkable film to see if the transparency of the heat shrinkable film is good, whether the color is bright, whether there is any damage, whether it is perforated, etc. 2. The heat-shrinkable film manufacturer reminds everyone, don’t forget to check the flatness of the heat-shrinkable film. You can pick a heat-shrinkable film at random to see if the heat-shrinkable film has wrinkles and signs of shrinkage. 3. Another thing is to look at the outer packaging of the heat-shrinkable film, look at the surface of the product name, manufacturer, date, quantity and other information, and the surface should be smooth, clean and free of dust. Brief introduction of the PVC heat shrinkable film produced by our company: width: 25mm-1400mm, thickness: 0.017-0.1mm, shrinkage rate: transverse shrinkage rate 45%-60% longitudinal shrinkage rate 25%-35% (can change the direction of shrinking, the longitudinal direction is large The horizontal direction is small, suitable for use in high-speed packaging machines). In fact, in our country, many edible packaging has been used in real life. For example, wax, oil, gelatin, etc. coated on the surface of food and fruit can effectively slow down the loss of water and extend the shelf life; the glutinous rice paper coated with the outer layer of candy and pastry is made of sweet potato, corn or wheat flour and other starches. It is used to prevent adhesion with the outer packaging; corn baking packaging and sausage casings of ice cream cones are typical edible packaging. For more related knowledge, please click:
