- Dec 26, 2017 -

In the current production work, we can see that people often use the stretch film to complete the packaging of the product.In this way, whether it is in the process of transport or storage, can prevent items from being contaminated or scratched. In other words, the main role of the retractable film is to stabilize, cover and protect the product.


In order to meet the practical application requirements, the stretch film must meet the following requirements at the same time: 1, has a strong puncture resistance; 2, good shrinkage; 3, the appropriate shrinkage stress. In addition, during shrinking process, no holes shall be generated.


It should be noted that, taking into account the frequent application of stretch film in outdoor applications, so in the production process also need to add a certain amount of UV anti-UV agent. This will not only improve the performance, but also can extend the use of time.


Under normal circumstances, the quality of the stretch film also need to have excellent transparency and good gloss, and even in low temperature and environmental conditions should still maintain a faster rate of contraction.When in high-speed situations, you should ensure better sealing. In addition, it should be able to store a longer period of time.


In fact, in practical applications, it is often used in the field of food or frozen products. Compared with other similar products, it not only has excellent self-adhesive properties, but also has excellent flexibility and tensile properties.


From the practical application of the situation, after the use of the stretch film, can effectively ensure the overall stability of the object, but also reduce the transport process of damage, collapse, scattered packages and so on. In addition, due to the high degree of transparency of the stretch film, the contents can still be seen after multi-layer wrapping.
