Title:
BIAXIALLY STRETCHED POLYPROPYLENE FILM AND PRODUCTION OF MOLDED OBJECT
Document Type and Number:
Japanese Patent JPH10202738
Kind Code:
A
Abstract:
To provide a film improved in drawdown at the time of molding and good in thermal moldability, and to produce a molded object by using the film.
This biaxially stretched polypropylene film is composed of a compsn. consisting of 100 pts.wt. of polypropylene and 5-50 pts.wt. of a petroleum resin. In this case, the C-axis orientation coefficient in the direction right- angled to the flow direction of this film is set to 0.30-0.45 and the surface orientation index of this film is set to 0.50-0.70. This film is thermally molded to produce a molded object.
