Basel Polyolefins Co., Ltd. introduced a new grade of impact polypropylene copolymer Clyrell 514L. The new grade is said to have been prepared using the Catalloy polymerization process and is characterized by high transparency and a wide processing temperature range, achieving the required hardness for the preparation of a FFS packaging container sheet.
According to reports, Clyrell 514L is a substitute for commonly used FFS resins such as PC and APET. The comparative test from the FFS machinery factory shows that the PP copolymer can be directly processed with the equipment and mold processing APET without equipment modification, and the PP copolymer injection stroke is 97% of APET, and the residual shrinkage is only 1% The haze and gloss indexes were 10.1% and 127.3%, respectively, while the APET haze and gloss indexes were 8.9% and 129.3%, respectively. In addition, PP copolymer food containers are 33% lighter than APET.
