Vacuum Packaging Machine Development History

Vacuum, the term is translated from the Latin vacuo, its meaning is nothing. In fact, vacuum should be understood as a space where gas is thin. In a given space, the state of the gas below one atmospheric pressure is collectively referred to as vacuum. The degree of gas thinness in a vacuum state is called a degree of vacuum, and is usually expressed by a pressure value. Therefore, the vacuum packaging is not actually completely vacuum, and the vacuum in the food container packaged by the vacuum packaging technique is usually 600-1333 Pa. Therefore, the vacuum packaging  is also referred to as a vacuum packaging or an exhaust packaging.

Vacuum packaging technology originated in the 1940s. In 1950, polyester and polyethylene plastic films were successfully used for vacuum packaging, and vacuum packaging was rapidly developed.

China's vacuum packaging technology was developed in the early 1980s, and vacuum inflatable packaging technology began to be used in small quantities in the early 1990s. With the promotion of small packaging and the development of supermarkets, its scope of application is more and more extensive. Some will gradually replace hard packaging, and the prospects are very promising.

It was the first development period from the 1950s to the mid-1980s, which began with the manufacture of simple air extractors. At that time, there were less than 20 enterprises producing vacuum equipment in the country, and the products were mainly obtained in medium and low-grade vacuum, such as the mirror coating machine cigarette packaging machine. From the late 1980s to the 1990s, it was the second period of China's vacuum industry development. During this period, the number of production enterprises increased to nearly 3,000, and the number of employees reached 35,000. After the technical transformation of the “seventh five-year” and “eight-five” technology, the overall level of the vacuum industry has been greatly improved. From the processing conditions, advanced production equipment such as CNC machine tools and resin sand castings of machining centers began to be equipped with enterprises. By 1996, due to the pull of the magnesium smelting industry, the vacuum industry has developed rapidly.

Food vacuum packaging machine
The food vacuum packaging machine vacuum-packs foods such as sausages, meat products, and biscuits. The packaged food can prevent mildew, quality and freshness, and prolong the storage period of the product. Simply press the vacuum cover to automatically complete the vacuum and seal.
Single room / double room
The vacuum of this type of equipment only needs to press the vacuum cover to automatically complete the process of vacuuming, sealing, printing, cooling and exhausting according to the procedure. The packaged product prevents oxidation, mildew, insects, moisture, shelf life, and freshness to extend the shelf life of the product.
Single chamber vacuum packaging machine
Desktop vacuum packaging machine
The desktop single-chamber vacuum packaging machine has good vacuum performance and is suitable for vacuum sealing packaging of meat, sauce products, condiments, preserved fruits, grain, soybean products, chemicals, medicinal materials and other products in the food industry. Suitable for vacuum packaging of a variety of plastic bag composite bags. The machine is small in size, light in weight and low in energy consumption, and is suitable for use in shops, supermarkets and homes. Vacuuming, sealing, cooling, and air intake to the cover are opened, and the whole process is automatically controlled.
