Plastic casing refers to a casing that uses a packaging material that has good barrier properties and can be retort-sterilized at high temperatures. Plastic casings use polyvinylidene chloride (PVDC), polyamide casing film (PA) and EVAL composite flexible packaging materials. Since PVDC domestic Nantong Resin Factory has a small number of products, PVDC casing films need to be processed from raw materials to equipment. Foreign purchase. PVDC is a heat-sensitive plastic that has a narrow processing temperature and is easily decomposed. Therefore, molding equipment has special requirements. Plastic casing film packaging materials have developed rapidly in recent years, and are mainly used for meat packaging. They include polyvinylidene chloride (PVDC) casings, nylon casings, nylon compound casings, and EVAL compound casings. It is widely used in the packaging of sausages, ham sausages, red sausages, powdered sausages, sandwiched sausages, garlic sausages, and meat sausages.
