At the same time, the quality requirements for plastic composite packaging products are getting higher and higher. Packaging users not only pay attention to the beauty and logistics performance of the packaged products, but also pay attention to the heat-sealing strength of the packaged products. Because the heat sealing strength of packaged products directly affects the packaging speed, transportation and sales. In actual production, each manufacturer regards the heat-sealing strength as an important quality index to control whether it is bag-making products or coil products used in automatic packaging production lines. The following is a simple analysis of the factors that affect the heat-sealing strength of the heat shrinkable film based on the actual production experience. The heat-sealing temperature and the heat-sealing temperature directly affect the heat-sealing strength of the plastic composite packaging product. Heat-sealing time The heat-sealing time of the automatic packaging machine or the old bag making machine is determined by the machine speed. When the heat-sealing temperature and heat-sealing pressure remain unchanged, the longer the heat-sealing time, the stronger the bond between the heat-sealing layers. However, if the heat-sealing time is too long, the heat-sealed parts of the composite film will be wrinkled and uneven, which will seriously affect the appearance quality of the product. Heat sealing pressure For the heat sealing strength of plastic composite flexible packaging, a certain heat sealing pressure is essential. Therefore, the heat sealing pressure is required to be moderate and uniform during the heat sealing process. If the heat-sealing pressure is not enough or uneven, bubbles will be generated in the heat-sealed part and false welding will result in poor heat-sealing. The heat-shrinkable film has high strength, high rigidity, stable appearance, and exquisite brightness and transparency. Convenient processing, convenient coloring, good printing functions, and extremely high printing resolution. For the brands that are seeking exquisite printing from time to time, completeness is an improvement in raw materials. Shrink film oriented polystyrene heat shrink film is a new type of heat shrink film packaging material that meets environmental protection requirements.
