Title:
SURFACE-TREATED POLYPROPYLENE FILM AND METALLIZED POLYPROPYLENE FILM
Document Type and Number:
Japanese Patent JPH0931221
Kind Code:
A
Abstract:
To prepare a surface-treated polypropylene film which is excellent in wettability after surface treatment, printability to printing ink, blocking resistance, heat resistance, transparency, metallizing properties and has very small reduction in the wettability with time and a metallized film excellent in metallizing strength.
A polymer composition comprising 97-80wt.% of a crystalline propylene polymer of ≥96% isotacticity and 3-20wt.% of a hydrogenated petroleum resin having a softening point of 90-140°C and a bromine value of ≤14 is used to produce polypropylene film and the film is subjected to flame treatment on at least one face to give the objective surface-treated polypropylene film.
