Shrinkage performance of heat shrinkable film

The shrinkage performance of the heat shrinkable film release time: 2018-10-04 　　 When the change in the process of shrinking under heat, it fully conforms to the heating pattern during the use of the trademark, and will not have a major impact on the container and the filled beverage. It can be seen The energy consumption in the use of labels has not increased, but will decrease slightly. Similarly, the lower natural shrinkage rate has made the popularization and use of heat shrinkable film a qualitative leap. Since the heat shrinkable film has almost no shrinkage at room temperature below 60°C, a series of confusions and problems in the transportation, storage, packaging, and film expiry period of the heat shrinkable film during the use of the heat shrinkable film have been solved, providing label manufacturers with Technical guarantee and created conditions for reducing costs.　　Environmental protection 　　The environmental protection adaptability of the heat shrinkable film is a power source for the development of this new material and an important reason for replacing PVC as a label material. With the development of the world economy, a sustainable and environmentally friendly concept and requirement has been continuously deepened and popularized in recent years. The so-called sustainability is for the effective and controlled use of resources. The development of new products has proposed recycling or change. Into such a requirement for energy. Compared with PVC, it has such a prominent point. Not only can it be recycled and reused, even after printing the trademark can be incinerated and converted into energy. Because it is non-toxic and tasteless, it does not produce any harmful gas, so it will not produce any pollution. On the contrary, PVC cannot be incinerated because it contains chlorine (chlorine gas generated after incineration will destroy the ozone layer). Even if it is recycled, the cost of recycling is relatively high, and the gold content of reuse is too low, and the gain is not worth the loss. In addition to the advancement of technical indicators, the economical and practical heat shrinkable film cannot be ignored: the low density of the material (its density is only 1.05 g/cm3; PVC 1.35 g/cm3, PET1.38 G/cubic centimeter); during the pre-processing and re-plasticization of the film, there are almost no crystal points (commonly known as fish eyes), which brings about the problem of reduced yield due to crystal points, and fundamentally changes ; Because of its good flatness, it can completely change the previous problem that PVC heat shrinkable film can only be printed in narrow widths, and can meet the requirements of wide-format high-speed printing, thereby increasing efficiency and bringing manufacturers the effect of reducing costs. Previous: Shrink film printing should fully consider the environmental performance of the ink
