The concept and function of vacuum packaging
Vacuum packaging protects products from environmental pollution and prolongs the shelf life of food, which can improve the value and quality of products. Since the successful application of polyester and polyethylene plastic films to commodity packaging in 1950, vacuum packaging machines have developed rapidly. In our daily life, all kinds of plastic vacuum packaging abound. Lightweight, sealed, fresh-keeping, anti-corrosion, and anti-rust plastic vacuum packaging covers many fields from food to medicine, knitwear, from precision product manufacturing to metal processing plants and laboratories. The increasing application of plastic vacuum packaging has promoted the development of plastic vacuum packaging machines and put forward higher requirements for them.
The development prospect of vacuum packaging machine
Vacuum packaging is also called decompression packaging, which is to extract all the air in the packaging container and seal it to maintain a high degree of pressure reduction in the bag. The scarcity of air is equivalent to low oxygen effect, so that microorganisms have no living conditions to achieve freshness. Applications include vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastic and its composite packaging, etc. Here we do a simple analysis of the future prospects of vacuum packaging technology.
