A block liner is a paperboard coated with wax on both side, and cut into a precise shape, which can be folded to match the freezing frame. It is used to freeze a frozen block. Frozen food block is a rectangle (Block Overall L*W*H: 482*252*62.7mm) of fillets, bits and pieces, mince, or pulp protected by a liner. Types of food packed in liners are fish, chicken, beef, pork, and various types of fruit and vegetables. The frozen blocks typically serve as a primary product form to be further processed within hours of production or years later after being pulled from frozen storage.
The purpose of a wax block liner is to protect food blocks from the time of packing until the cartons are removed. Frozen blocks are vulnerable to dehydration and oxidation during storage and transport to their next destination.
