At present, most fresh beef and mutton on the market are packaged in vacuum bags to meet the requirements of refrigeration and preservation. Some fresh meat is packaged in plastic trays and covered with film to prevent moisture loss and product pressure. Nowadays, the 7-layer co extruded high resistance thermal insulation shrink bag of Peidi Packaging has been widely used.

Seafood and fish products are prone to enzymatic spoilage and the production of toxic bacteria, and most fish are sold in vacuum packaged frozen form. They need to extend the shelf life as much as possible. Therefore, vacuum bags are widely used for packaging them to maintain freshness and extend shelf life.
