If we compound the high temperature cooking plastic film, the aluminum foil bag will become the same as the iron can, or even more than the iron can. More advantages. For example, it is easy to carry, convenient to transport, not easy to deform, and has low production cost. After strict vacuuming and cooking, it can effectively extend the storage time of the product and can be stored at room temperature.   The picture below is of different shapes of aluminum foil bags we photographed.
