What is the application analysis of plastic blowing machine in food plastic?

The plastic bottle blowing machine is a packaging technique in which the articles are loaded into airtight containers and vacuumed before the container is sealed, so that the sealed container is basically free of air. Plastic bottle blowing machine technology originated in the 1940s. In 1950, polyester and polyethylene plastic films were successfully used in plastic bottle blowers. Since then, plastic bottle blowers have been rapidly developed. China’s plastic bottle blowing machine technology was developed in the early 1980s. 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 becoming more and more extensive. Some will gradually replace hard packaging, and the prospects are very promising.

The characteristics of plastic bottle blowers are as follows:
Exclude part of the air(oxygen) in the packaging container, which can effectively prevent food spoilage.
2, the use of excellent barrier(airtightness) packaging materials and strict sealing technology and requirements, can effectively prevent the exchange of packaging content materials, that is, to avoid food weight loss, loss of taste, but also to prevent secondary pollution.
3, the inner gas of the plastic bottle blowing machine container has been eliminated, accelerating the conduction of heat, which can improve the thermal sterilization efficiency, but also avoid the heating sterilization, due to the expansion of the gas and the packaging container ruptured.
