A Polypropylene film additive by Eastman has taken 15 years to gain EU approval. Eastman Chemical B.V.'s Plastolyn R1140 hydrogenated hydrocarbon resin complies with a listing for petroleum hydrocarbon resin (hydrogenated) in the Fifth Amendment to the Plastics Directive 2002/72/EC, along with Regalite resins R1100 and R1125. Plastolyn R1140 is a specialty plastic additive designed to modify polypropylene; as an additive it is effective at addition levels between five to ten per cent of the final packaging film, claims the spokesperson. The resin, claims the manufacturers, allows producers to produce stiffer, thinner and visually clear film:
The Fifth Amendment listing follows a positive opinion from the European Food Safety Authority (EFSA), which is responsible for the safety evaluation and approval of food contact materials including plastic materials. Plastolyn R1140 already has a number of Food and Drug Administration (FDA) food contact clearances, the most relevant to polypropylene modification is FDA 175-1520 which allows for direct food contact with up to 25 per cent weight addition to typical polypropylene food wrapping applications such as twist wrap for candy.
Regalite also enables plastic wrap to be thinner, clearer and stiffer, and offers at least 20 per cent more moisture resistance than traditional films, ensuring not only prominent product display but reduced spoilage and longer shelf life. It is suitable for food packaging applications in the coffee and tea, confectionery, bakery and snacks as well as pasta and noodles sectors.
