KREHALON PVDC casings are used widely by the meat, poultry, fish, cheese and other food manufacturing industries as well as for some non-food applications. These industries use to the full the protection gained from the exceptional barrier properties. KREHALON PVDC casings are available in an attractive range of colours, sizes and various converting formats designed for all modern filling and clipping equipment.
