Hot Slip Shrink Film: The Key to Cracking Packaging Adhesion

The most significant advantage of hot slip shrink film is its excellent hot slip property. This property seems simple, but it directly determines the smoothness of the packaging process and the perfection of the final packaging effect. When the film undergoes the heating and shrinking process, the temperature change will intensify the molecular activity on the surface of the material. If there is insufficient hot slip, the intermolecular force will be significantly enhanced, causing the surface of the film to stick to each other after shrinking. This adhesion will make the packaging lose its proper flatness and fit, which may cause unnecessary trouble in the subsequent storage and transportation links.

Basic performance guarantee of hot slip shrink film
Hot slip shrink film has all the basic properties that a high-quality shrink film should have. Its shrinkage rate is stable and can adapt to products of different shapes and sizes. It shrinks evenly during the heating process and tightly wraps the product. It will not cause the packaging to be loose due to insufficient shrinkage, nor will it cause the product to be squeezed and deformed due to excessive shrinkage. It has good puncture resistance and toughness. When facing products with sharp edges or heavy weight, it can effectively resist external impact, avoid damage during packaging and transportation, and ensure the safety of the product. The film has strong chemical stability and can adapt to a variety of environmental conditions. Whether it is a humid warehouse or a dry shelf, it can maintain stable performance and will not age or become brittle due to environmental changes. ​

Hot slip shrink film inherits and upgrades excellent characteristics​
JT02 achieves comprehensive performance improvement while maintaining the core advantage of hot slip. JT01 has won wide recognition in the market for its excellent shrink consistency, temperature resistance and compatibility with various packaging equipment. On this basis, JT02 further enhances the hot slip performance, making its application range more extensive. Whether it is used in industries such as food and medicine that have extremely high requirements for packaging hygiene, or in fields such as electronics and hardware that require strict protection, JT02 can handle it calmly. Its stability in high temperature environments is particularly outstanding. In a continuously operating packaging production line, it can still maintain stable performance after repeated heating and shrinking cycles. ​

Material and process characteristics of hot slip shrink film​
The excellent performance of hot slip shrink film comes from strict control of material selection and production process. In terms of materials, it is usually based on polymer materials, and the optimization of hot slip properties is achieved by adding specific functional additives. These additives form a stable molecular structure inside the material, which does not affect the shrinkage performance of the film, but can also work at high temperatures to reduce the surface friction coefficient. In terms of production technology, from raw material mixing to extrusion molding, and then to stretching treatment, each link is precisely controlled. During the stretching process, by controlling the stretching temperature, speed and direction, a uniform molecular arrangement is formed inside the film, which not only enhances its mechanical properties, but also lays the foundation for the stable performance of hot slip properties. This dual control of materials and processes allows hot slip shrink film to have excellent performance while ensuring product consistency and reliability. ​

Expansion of application scenarios of hot slip shrink film
Thanks to its comprehensive performance advantages, the application scenarios of hot slip shrink film are constantly expanding. In the food industry, it can be used for the packaging of frozen products such as meat and seafood. It can still maintain good flexibility and sealing in low temperature environments. At the same time, the hot slip property ensures that there will be no adhesion due to the hardening of the material caused by low temperature during the packaging process. In the pharmaceutical field, for drug packaging that requires a strict aseptic environment, the chemical stability and hygiene of hot slip shrink film meet industry standards, and its tight packaging effect can effectively isolate external pollution. In the packaging of daily necessities and industrial products, it can not only provide beautiful outer packaging for cosmetics, detergents, etc. to improve the product grade, but also provide collective packaging for small mechanical parts, electronic components, etc., which is convenient for storage and transportation. Whether it is the independent packaging of a single product or the collective packaging of multiple products, hot slip shrink film can meet the packaging needs of different scenarios with its strong adaptability. ​
