Vacuum preservation is the best guarantee to maintain the quality of raw food which still needs to be processed, and of already cooked food. Durability and freshness of the product are ensured by the almost total absence of oxygen, achieving a 99% maximum vacuuming. In fact, even if it is the wrapping which protects the product from external agents and odors, it is the percentage of vacuum inside the bag that extremely slows down the proliferation of bacteria that causes its deterioration. We at VALKO, where this technology (and not only this) is our core business, have developed a wide range of countertop or wheeled vacuum chamber packaging machines, available in various models and sizes and suitable for the most diverse businesses, such as supermarkets, labs, butcher shops, delicatessen, restaurants, etc.
