Processing aids for enhanced machine direction orientation rates and property enhancement of polyolefin films using hydrocarbon waxes |
摘要 |
The present invention disclose a method for the orientation of a high density polyethylene ("HDPE") film. The process of the invention comprises forming a HDPE-wax mixture by adding to a HDPE batch a normally solid hydrocarbon wax. The HDPE-wax mixture is subsequently stretched into a film at an orientation temperature below the film's melt temperature. The hydrocarbon wax is characterized by having a drop point equal to or lower than the melting point of the HDPE film. The present invention also provides a film made by the process of the invention and a master batch thereof.
