Because the growth and division of microorganisms require the participation of oxygen, the spores and hyphae of microorganisms are strongly inhibited under anoxic conditions. Thereby, the food in the bag is preserved, and the probability of microbial contamination is reduced.

Q:Is there any identification on the vacuum package?

Continue ink jet printer (continuous spraying machine), referred to as CIJ inkjet printer. The principle of operation is that the ink is ejected continuously through a single nozzle and is broken by crystal oscillation to form ink dots. After the ink point is charged and deflected at high pressure, the ink is scanned on the surface of the moving object. Such as Domino A100.
