In our life, a variety of pouch vacuum packaging is in everywhere. Lightweight, sealed, preservation, corrosion, rust-proof plastic vacuum packaging throughout from food to pharmaceuticals, knitwear, manufactured from precision products to metal processing plants and laboratories and many other areas. Plastic vacuum packaging is used widely to promote the development of pouch packaging machine supplier China, but also put forward higher requirements.
Currently, food packaging machinery research and development is moving in high-speed, multi-functional and intelligent control of the direction of development in order to meet market demand. Vacuum-packed features are as follows: 1, excluding the packaging container portion of air (oxygen), can effectively prevent food spoilage. 2, the use of barrier (airtight) excellent packaging materials and sealing technology and strict requirements, can effectively prevent the exchange packing material content, can prevent food weight loss and loss of taste, but will also prevent secondary pollution. 3, the gas inside the vacuum packaging container to be removed and accelerates heat conduction, which can improve the thermal efficiency of sterilization, but also to avoid the time of heat sterilization, since the expansion of the gas leaving the containers rupture.
In the food industry, vacuum packaging applications is very common, a variety of cooked products such as chicken, ham, sausages; pickled products such as various sorts need fresh food pickles and soy products, fruit and other increasingly used vacuum package. After vacuum-packed foods long shelf life, greatly extend the shelf life of food.
