摘要：
The invention relates to polypropylene for preparation of films, in particular, biaxially oriented polypropylene (BOPP) films. The structural characteristics of the claimed polypropylene allow to increase the processing speed (450 m/min and more) in the process of producing BOPP films. The invention also provides BOPP films, at least one layer of which comprises said polypropylene. Films according to the invention can be used for the packaging, including packaging for food products, adhesive tapes, labels, etc.
