Classification of PVC heat shrinkable film

PVC heat shrinkable film purifies our eyes and changes our living habits with its clean, environmentally friendly, practical and affordable image. Over the past 30 years of reform and opening up, China has made great economic achievements, but the environmental pollution and ecological damage caused by development have become increasingly severe and prominent. The environmental problems China faces are more severe than any other country, such as Japan, the United States, and other developed countries in Europe and the United States have paid more and more attention to environmental protection, and the opening of new energy technology has given attention and support, which has achieved the upgrading and development of industrial structure. As the world’s factory, China is still experiencing high energy consumption. In the industrial production stage of emissions, industrial pollution has become the culprit of Chinese-style pollution, and the high-carbon lifestyle of Chinese people is the Achilles heel of Chinese-style pollution. It can be seen that the environmental problems facing China are a social issue. PVC heat shrinkable film material is one of the largest plastic products in the world. It is cheap and widely used. PVC resin is white or light yellow powder. According to different purposes, different additives can be added, and PVC plastics can present different physical and mechanical properties. Adding an appropriate amount of plasticizer to the polyvinyl chloride resin can make a variety of hard, soft and transparent products. PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for floors, ceilings and leather surfaces. Polyvinyl chloride hard boards are widely used in the chemical industry to make various storage tank linings, corrugated boards of buildings, door and window structures, wall decorations and other construction materials.

Three ways to reduce the printing of PVC heat shrinkable film labels

In offset printing, traditional embossing (Rou Yin), gravure printing and screen printing, PVC heat shrinkable film label printing gravure printing, mainly due to the large number of domestic gravure printing machines, the cost of printing and gravure printing, and The characteristics of the thickness of the ink layer, bright colors, rich layers, and such labels, long printing is mainly used, and the intaglio printing plate reaches tens of millions, such a large-capacity work is undoubtedly the most cost-effective. However, with the increasingly fierce market competition, the development of PVC heat shrinkable film and flexographic printing, machinery, ink and other technologies, the proportion of flexographic printing has increased year by year. But from the customer's point of view, more attention is paid to satisfying quality and reducing costs. What kind of printing is next.

High strength PVC heat shrinkable film

Packaging film has the characteristics of puncture resistance, ultra-high strength and high performance, and is widely used. However, many customers report that the surface of the packaging film will have the following spots during use. We have followed up with the packaging film manufacturer to understand why. Found the reason.
