PROCESSING METHOD FOR RECLAIMING BIAXIALLY ORIENTED POLYESTER FILM AND EQUIPMENT THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method of the reclamation processing of a biaxially oriented polyester film which recycles the biaxially oriented polyester film as a resin raw material and to provide equipment therefor.

SOLUTION: The method comprises a first step of obtaining a crushed product C by crushing the biaxially oriented polyester film A at≤200°C into an average particle diameter of≤5 mm, a second step of obtaining a dried product D with a moisture content of≤0.1 mass% by drying the crushed product C, and a third step of obtaining a molded product E by injection-molding the dried product D. This enables the biaxially oriented polyester film, which has been processed into a fuel by the conventional thermal recycling method, to be recycled as a resin raw material and can contribute to resources saving and reduction of carbon dioxide gas.
