incompatible mixes degrade physical properties — even a small amount of HDPE in PP, for example, will cause problems. Compatibiliser additives work to make different types of polymers, or polymer and filler combinations, compatible with each other in a recycled compound. Ampacet’s ReVive 311A Compatibiliser is designed to allow recycling of multi-layer films containing PE layers with polyamide and/or EVOH barrier layers (these polymer combinations s would normally be incompatible). The ReVive additive was initially designed for in-house recycling of film edge scrap. “Customers add ReVive to virgin, multimaterial films so that they can regenerate the scrap and edge trim back into the hopper that feeds the PE layer of the film,” says Becker. “Ampacet ReVive maintains good flow proper-
ties at the recommended letdown ratios, among the lowest in the market, and can generally be added to the PE bulk layers as a drop-in as vali- dated in testing by leading industry partners,”
according to Jim Morrison, Ampacet Strategic Business Manager, Flexible Packaging. Another use of ReVive is for addition to films containing multi-material PCR to help enhance physical and aesthetic properties. Ampacet says it went through a rigorous testing process in the US to obtain APR [US Association of Plastic Recyclers] critical guidance recommendation for the additive and subsequently How2Recycle Prequalification status for Store Drop-Off from the Sustainable Pack- aging Coalition. The How2Recycle standardised package labeling system is used in the US and Canada to provide consistent information to consumers. Although prequalification is not the final designa- tion for a package label, it is a tool for consumer product brands to see how they can achieve circular economy goals, says Ampacet’s Becker. “We pursued these qualifications because many of our direct customers sell to brands who like to use this label on their packaging so that consumers know that these packages can be recycled and how to get them to the right facility to ensure they are recycled,” she says. Acti-Tech maleic-anhydride (MAH)-grafted
compatibilisers from Nordic Grafting Company (NGC) can be used for in-house recycling at converters, during repelletising at a recycler, or in compounding of recyclate. The Compounding Company’s Yparex MAH-modified polyolefin compatibilisers are used in post-industrial and post-consumer recycling streams. SK Functional Polymer (SKFP) also has different grades of compatibilisers suitable for a wide range of recycled blends. Meanwhile, US start-up Intermix
