Fast food products are convenient to eat and are very popular with modern consumers. There are two main packaging methods for fast food products, one is plastic packaging, and the other is vacuum packaging, which is very important for extending the shelf life of food In terms of the vacuum packaging machine, what kind of instant products are suitable for vacuum packaging machine? How long can the vacuum packaging machine extend its shelf life? In response to these doubts, we will explore together.
Regarding the categories of fast food products, they are currently mainly divided into these categories.
One type is convenience foods in plastic packaging. For example, instant noodles, snail noodles, instant rice noodles and other fast food products are packaged in either ordinary sealed bags or drums in plastic packaging.
