The packaging industry has undergone dramatic changes, and the future of heat shrinkable film packaging machines

The packaging industry is undergoing drastic changes, and the heat shrinkable film packaging machine can be expected in the future. Release time: 2018-04-12 　　 Beverage secondary packaging refers to the packaging and sealing process performed after beverage bottling, sealing, and sleeve labeling, generally including boxing and The two methods of covering film existed initially for the convenience of transportation, and later they also derived features such as visualization and bundling sales. There are currently three general forms of first packaging for beverages: metal cans, boxes, and bottles (plastic, glass). Carton packaging can be used in the secondary packaging, with sealing and packaging integrated machines, sealing machines and other equipment; metal cans Beverages in packaging, carton packaging, and plastic bottles can be packaged in a film-sleeve way, and a heat shrinkable film packaging machine is required in this process. In terms of the comparison of the two secondary packaging methods, carton packaging can be applied in a wider range, the technology emerged earlier, the equipment and technology are more mature, and the consumers faced are mainly dealers, and the latter are mostly sold in the way of dismantling and retailing. , But since the carton industry began to skyrocket at the end of last year, the price of raw materials has become a factor that many businesses have to consider; while film packaging has a narrow scope of application and heat shrinkable film packaging machines appeared late, but the raw materials are mostly PE film, and the price is relatively high. It is cheap, and when facing consumers, it is usually sold as a whole package, so it has become the packaging method of choice for more and more beverage companies.　　 heat shrink film packaging machine is usually used in conjunction with the film sealing and cutting machine. The shrink film is installed on the outside of the product and sealed by the film sealing and cutting machine, and then it enters the heat shrinking machine for heating, so that the packaging material shrinks and tightly wraps the product. The packaged items have certain anti-fouling and impact resistance capabilities. Different beverage companies on the market have different requirements for beverage packaging bottles (cans), including 6 bottles, 12 bottles, and 24 bottles. Therefore, the film sealing and cutting machine and the heat shrinking machine are required to meet the market requirements.　　 Because the secondary packaging process is after the food packaging, in order to make the entire production line coherent, the secondary packaging needs to keep up with the filling and sealing speed and realize automation. According to the author's understanding, Beijing Yongchuang Tongda Company has perfected the shrink film packaging model with a packaging speed of 10-130 bags/min, which can meet the needs of production lines with a speed of 6000-54000BPH. At present, there has been an automatic heat shrink packaging machine on the market, which is a combination of film sealing and cutting machine and heat shrinking machine, which can realize the integration of automatic film feeding, bag making, smoothing the surface, cutting film and packaging, and heat shrink packaging.　　 At present, what we see on the market is not only transparent film packaging, but also colorful packaging film. The printing of corporate posters not only improves the recognition of the product, but also improves the aesthetics of the packaging. This also puts forward certain requirements on the accuracy of the heat shrinkable film packaging machine. In addition, the author has learned that the outer film packaging material used for beverage packaging is generally PE film. As the country's environmental protection requirements become increasingly strict, how to adapt to the new green packaging film will be the focus of future consideration.　　 With the repeated increase in the price of cartons, it is the common demand of many food and beverage companies to find replacements for secondary packaging. As one of the alternatives, the low price of heat shrink packaging will be its biggest competitive advantage. From this point of view, the future of shrink film packaging machines is worth looking forward to. Previous: Physical and chemical properties of pvc heat shrinkable film
