POLYPROPYLENE INFLATED FILM

摘要

PROBLEM TO BE SOLVED: To provide a propylene polymer increased in melt strength and the modulus of elasticity and capable of being used in the production of an inflation film. SOLUTION: An inflation film or sheet material contains a polypropylene polymer having wide mol.wt. distribution with mol.wt. distribution Mw/Mn of about 40-60, a melt flow rate of about 0.5-50dg/min and xylene insoluble substance content of 94% or more at 25 deg.C. A mixture of propylene polymer material having wide mol.wt. distribution and a different phase olefin polymer compsn. can be also used.
