| Ixan® PVS 855 is a PVDC resin-based blend for the extrusion and coextrusion of barrier films mainly used in flexible food packaging applications (heat shrinkable or not). It is recommended for applications requiring very good oxygen and water vapor barrier. Ixan® PVS 855 is a copolymer of vinylidene chloride and methyl acrylate supplied as an off-white free-flowing powder. Applications: Food Packaging Features: Moisture Barrier; Oxygen Barrier PROCESSING
- As supplied, Ixan® PVS 855 is formulated for the extrusion or the coextrusion of multilayer barrier films. It can be processed by extrusion using machine designs that allow streamlined plastic flow in order to minimize the risk of plastic hold-up in the equipment. - Regarding construction materials for the machine, Solvay Recommends that the parts in contact with the melt PVDC have high corrosion resistance and contain no catalytic materials (see below), i.e. those made of high Ni alloys like Xaloy®, Duranickel®, Colmonoy®, or Hastelloy®. - It is essential that the temperature of Ixan® PVS 855 melt is kept below 180°C and the residence time is minimized. - Thermal degradation during melt processing will release hydrogen chloride (HCl) gas. This reaction is catalyzed by the presence of Iron (Fe), Copper (Cu), and Zinc (Zn). STORAGE
- Keep in a well-ventilated and dry place
- Do not store in heat or direct sunlight
- Keep only in the original package at a temperature not exceeding 40°C ISO CERTIFICATION
The implemented management system for the production, internal transfer and delivery, design and development of Ixan® vinylidene chloride copolymers (PVDC) produced in Tavaux has been assessed and found to meet the requirements of ISO 9001: 2008, ISO 14001: 2004 and OHSAS 18001: 2007.
