  • the material is compressed into a single block within a plastic bag, and is immediately sealed within a vacuum, it ensures that the material is kept clean and reduces the need to double handle the material. Also, since the material is packaged within a vacuum, atmospheric pressure helps to hold the compressed material as a single homogenous block when the material is released from the apparatus (11). This is helpful since a product like cheese will not reconstitute itself into a single block that will hold together in the same way that an original block of cheese will hold together.
