YX 37 F
YX 37 F is a polypropylene homopolymer developed for the high speed extrusion of transparent cast and blown ﬁlm. YX 37 F is formulated with an effective slip and antiblocking package. YX 37 F is suitable for the extrusion of low thickness ﬁlms and can be used for ﬁlms from 15 up to 150 urn.
In compahson with standard polypropylene types for ﬁlm production, YX 37 F allows for faster processing due to its peculiar structure and composition.
Films made with YX 37 F show a good behaviour on the winding rolls and in the cutting section and feature a very high transparency, a high gloss and a good printability after corona treatment.
Because of their high transparency and good handling properties, films made with YX 37 F are used for the production of shopping bags and packaging for snacks, bakery products, books, blankets, hosiery and shirts. Another major application is the production of stationery folders, twines and ropes.
