FLEXIBLE PACKAGING | INNOVATION
the extruded films in the secondary process show excellent processability on W&H machines. By the use of compatibilisers, the properties of the re- extruded films are very consistent.”
Compatibilisers A compatibiliser in Dow’s RecycleReady Technology was the first to receive recyclability approval by industry organisation RecyClass, the company announced in April last year. RecycleReady PE coextruded film containing EVOH and Retain 3000 compatibiliser was tested by Aimplas in accord- ance with the RecyClass Recyclability Evaluation Protocols. The results showed that when the amount of EVOH is limited to 4.75% and the amount of compatibiliser to 2.25%, this technology is fully compatible with recycling of natural and coloured flexible PE, said Dow. It added that further assess- ment shows recycled material containing up to 25% of film with RecycleReady technology can be used in high-quality applications such as PE blown films. Two Dow adhesive systems commonly used in PE film packaging applications have also been approved as recycling-compatible by RecyClass. The approval covers solvent-free MOR-Free L
75-300/ CR88-300 and water-borne Robond L-350/ CR-3 lamination adhesives. In September last year, RecyClass announced
approvals for PE film lamination adhesives pro- duced by other companies. COIM’s Novacote NC 560 A + CA 101 was found to be fully compatible with recycling. The tests carried out by Aimplas showed that use of the adhesive had only a very slight effect on the colour of final recyclates. Morchem’s PL 2727 AR + CF-740 R laminating adhesive was also approved after Aimplas testing showed no deviations to the quality of recyclates when processing PE films containing the adhesive.
