TOPAS: Film extrusion grade of COC
Used to produce a range of multilayer packaging film applications including metallized film, twist film, hot fill, and shrink labels in thicknesses up to 100 microns, TOPAS Advanced Polymers’ 7010F-600 COC is a new film extrusion grade of cyclic olefin copolymer (COC) that delivers a glass transition temperature of 110°C, and strong extrusion capabilities for multilayer food packaging.
In terms of glass transition temperature, 7010F-600 COC is positioned between TOPAS 8007 (80°C) and TOPAS 6013 (140°C). It is optimized for robust extrusion performance and offers the same ease of processing as TOPAS 8007F-400. TOPAS 7010F-600 does not require pre-drying and can be run on blown film systems with or without grooved feed extruders at process temperatures of 230°C or above. It can also be processed on thin cast film lines with low haze over a wide process temperature range.
TOPAS 7010F-600 resin is typically used in multilayer structures with polyolefins and barrier resins such as polyamide (PA) and ethylene vinyl alcohol (EVOH). TOPAS 7010F-600 can be processed on conventional extrusion equipment, providing highly transparent and defect-free film. The material complies with U.S. Food & Drug Administration (FDA) food contact regulations, with monomers and additives listed in EU Plastics Regulation 10/2011.
TOPAS COC resins are amorphous polymers that offer high transparency, moisture barrier, high rigidity and strength, biocompatibility, and good electrical insulation properties. Suitable for applications in areas such as medical devices, food and pharmaceutical packaging, optics, and electronics.
