The Dow Corning AMB-12235 masterbatch for polyethylene blown film by DuPont Transportation & Advanced Polymers combines an anti-block agent with a compatible slip additive, to improve film processing and ensure consistent quality.

Called a new-generation silicone-based masterbatch, AMB-12235 has been approved for food contact in Europe, the US and China and is claimed to deliver a low coefficient of friction (COF) over time. It also helps prevent migration to the film surface that can affect downstream operations and helps reduce film blocking that can cause damage – all at cost-effective, low loadings. 

“This new technology advancement demonstrates our commitment to the success of the packaging industry by supplying silicone- based solutions that help customers achieve seamless throughput,” said Christophe Paulo, industrial and consumer strategic marketer for EMEA at DuPont. “When customers asked us for a simpler way to optimise PE film processing, we developed this high-performance combined masterbatch. It helps film-makers avoid spending time and effort to calculate the right ratio of anti-block and slip additives by trial and error.”
