Plastic bottle
blowing machine is packed the goods into air tightness after container, the container before sealing process of pumping air into vacuum state, make basic without air sealed container after a packaging technology.
Plastic bottle blowing machine technology originated in the 1940 s.
In 1950, polyester, polyethylene plastic film is used for plastic bottle blowing machine successfully, then the plastic bottle blowing machine gets rapid development.
Our plastic bottle blowing machine 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 package promotion and supermarkets, its scope of application is more and more widely, some will gradually replace the rigid package, the future is very promising.
The term vacuum, translated from the Latin vacuo, its significance is nothing.
Actually lower vacuum should be understood as a gas of space.
, within a specified space under an atmospheric pressure gas state are collectively referred to as vacuum.
Vacuum degree of thin gas called vacuum (
真空度)
, usually expressed as pressure value.
So plastic bottle blowing machine is actually not completely vacuum, plastic bottle blowing machine technology of food packaging container vacuum degree in the 600 - usually
1333Pa。
So, the plastic bottle blowing machine called vacuum packing or exhaust.
The characteristics of the plastic bottle blowing machine is as follows: 1, eliminate the air within container (
Oxygen)
, can effectively prevent food deterioration.
2, using the barrier property (
Air tightness)
Excellent packaging materials and sealing technology and strict requirements, can effectively prevent the packing content material exchange, can lose weight, avoid food flavor, and can prevent the secondary pollution.
3 container, plastic bottle blowing machine internal gas has been ruled out, speeding up the heat conduction, it can improve the efficiency of thermal sterilization, also avoid the heating sterilization, packaging container cracking due to the expansion of gases.
In the food industry, plastic bottle blowing machines is very common, all kinds of cooked products, such as chicken, ham, sausage, etc. ;
Pickled products such as all kinds of pickled vegetables and soy products, dried fruit, etc are used more and more various need fresh food plastic bottle blowing machine.
After long food freshness plastic bottle blowing machine, greatly extend the shelf life of food.
