    Heat shrinkable film is used for the sale and transportation of various products. Its main function is to stabilize, cover and protect the product. The shrink film must have high puncture resistance, good shrinkage and a certain shrinkage stress. During the shrinking process, the film must not have holes. Since shrink films are often suitable for outdoor applications, UV anti-ultraviolet agents need to be added. How many features does the heat shrink film have?


    1. It has high flexibility, not easy to break, strong anti-blasting force, strong impact resistance, strong tear resistance and strong tensile force, which can replace box packaging.


    2. The shrinkage rate is large, and the articles can be wrapped tightly after heat shrinking. If it is made into a PE straight-through bag (both ends of the bag are opened) and heat-shrinked, the two ends of the opening can lift the articles, which can bear the weight of 15KG, which is convenient for handling.


    3, good transparency, light transmission rate of 80%, can display the product, can invisible publicity of the product, but also reduce distribution errors in the logistics link.


    4, moisture-proof, waterproof, dust-proof, not only can achieve the packaging effect, but also beautiful products, protect the product.


    5. Tasteless and pollution-free are environmentally friendly packaging materials.


    The heat shrinkable film product has strong adhesive force, so it is very effective for manual winding or machine winding. In addition, the transparency of this product is very high, so the contents are still clearly visible after multi-layer wrapping.
