The new resin compatibilizer from Dow is said to be giving millions of pounds of barrier film scrap a second chance at life. Based on a reactive ultra-low viscosity, RETAIN Polymer Modifiers allow pelletized barrier films, containing materials like ethylene vinyl alcohol (EVOH) or polyamide (PA), to be more evenly dispersed into a polyolefin matrix. Compared to other control films, the technology is helping make packages clearer, maintain mechanical properties, and significantly reduce gels in films produced from barrier film recycle streams.
RETAIN Polymer Modifiers help support converters’ landfill waste goals, and take plastic packaging to a new level. The technology also enables the use of ‘post-industrial recycled content’ claims, and helps trim down costs associated with collecting, packaging, and selling scrap materials.
The technology has benefits beyond sustainability. After many vigorous trials, RETAIN Polymer Modifiers demonstrated impressive optical and physical properties, and improved processability, according to the company.
The product portfolio also: uses the advanced chemistry developed for Dow’s AMPLIFY TY Functional Polymers; achieves the same clarity as a control film; maintains or increases dart values; delivers the option to replace a portion of PE purchases with in-process barrier film trim; and makes better use of existing recycling streams.
