It is suitable for both extrusion and co-extrusion processes and is particularly recommended for use as barrier layers in multilayer food packaging films (heat shrinkable or not).

Ixan® PVS 856 is compliant with FDA and EU 10/2011 requirements and is supplied as a blue-tinted free-flowing powder.

Applications: Food Packaging

Features: Moisture Barrier; Oxygen Barrier

PROCESSING
- As supplied, Ixan® PVS 856 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 856 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.
