Use value of stretch film packaging machine
Use value of stretch film packaging machine. Vacuum packing machine technology originated in the 1940s. In 1950, polyester and polyethylene plastic film was successfully used in vacuum packaging, since then, vacuum packaging has developed rapidly. China's vacuum packing technology is developed in the early 1980 s, and vacuum packaging technology in the early 1990 s began to use small amounts, along with the development of the small packaging of promotion and market, its scope of application is more and more widely, so a lot of need vacuum packaging production enterprises in the choose and buy fully automatic vacuum packaging machine does not understand its features, and let me take you know the one of vacuum packaging machine, stretch film packaging machine.
Use value of stretch film packaging machine. Stretch film vacuum packaging machine is the main function of oxygen, is beneficial to prevent food spoilage, its principle is simple, because food metamorphism causing mold mainly caused by the activity of microorganism, and the survival of most microbes (such as yeast and mould) are need oxygen, and vacuum packing is using this principle, the packaging and food within the cell oxygen smoke, lose microbial "survival environment". When the oxygen concentration in the package is less than or equal to 1 percent, the growth and reproduction rate of microorganisms will drop sharply. When the oxygen concentration is less than or equal to 0.5 percent, most microorganisms will be inhibited and stop reproducing. The price of vacuum packing machine is different according to different configuration.
Use value of stretch film packaging machine. Stretch film vacuum packing machine has the film conveying system, lower die guide part, system, basement membrane preheating zone, hot forming area, packing area, heat sealing, cutting and edge material recycling system, control system, etc., the whole machine adopts modular structure design, can according to user's need to increase or decrease in all kinds of devices, so as to increase or decrease and change a variety of functions. The development of packaging machinery is greatly welcomed by people.
Use value of stretch film packaging machine. This machine USES the forming mold, first heats the thin film, then USES the forming mold to wash into the container shape, then the packing material into the formed lower membrane cavity, then carries on the vacuum packing. The film used in the packaging is stretch film, soft film and hard film, this film has the characteristics of good formability, high transparency, can block oxygen, heat resistance, flatness, sealing, fog resistance, easy to open. This kind of film is equipped with thermoforming packaging machine, which can not only pack solid, liquid, soft objects, fragile products, but also carry out vacuum soft film packaging, hard film inflatable packaging, blister packaging and so on.
