With the progress of times, products are becoming more and more complicated and diverse, and accordingly the functions of packaging are increasing. The wave of high technology has pushed the packaging to a higher level of development, and the modified atmosphere packaging (MAP) technology will surely have a place in the era of intelligent packaging. With some food and fruit and vegetable preservation products increasingly becoming the mainstream of food consumption and taking up an increasingly larger share in the domestic and international markets, applying the MAP technology to the preservation of food can greatly extend the shelf life of food and thus has great market potential.
The principle of the compound MAP preservation packaging machine is a brand-new food and fruit and vegetable preservation packaging equipment developed on the basis of vacuum packaging machines and nitrogen flushing packaging machines. Its most distinctive feature is that it solves the following two problems: 1) after vacuum packaging and subsequent sterilization by high temperature, the taste of food is greatly damaged; 2) aseptic packaging is required for nitrogen flushing packaging, which involves large investment. Through compound gas flushing packaging, the original taste and flavor of food can be ensured, and the original juice, flavor and appearance of food can be guaranteed.
