Practice of PE heat shrinkable film

There are two important reasons why polymer protective film wholesale products are widely used in building materials. One is the function of PE, and the other is the low investment and high output of PE. The heat shrinkable film has high light resistance and fire resistance, ensuring a heat shrinkable film. Plastic films that shrink and heat shrink when heated are required to be stable at room temperature. In addition, a thermal shrinkage of more than 50% in one direction is relatively ideal. The characteristic of heat-shrinkable plastic film packaging is that the sticker is transparent, reflecting the image of the product. Tie the packaging tightly, good acid resistance, prevent Zheng Zhixun, moisture, mildew, no recovery, and anti-counterfeiting function. Heat-shrinkable plastic films are used for packaging convenience foods, beverages, electronic appliances, metal products, etc., especially shrink labels as the main application area. At present, the popular packaging in the shrink film industry is mainly based on plastics and paper. The blow molding industry, which is based on plastic hair dryers, has a larger proportion in the shrink film industry. However, as the paper industry requirements become more stringent, new indicators of green and energy saving are increasing. The paper industry’s threshold has increased, and the cost of the paper packaging market has increased and prices have risen.
