Polypropylene Cast and Blown Film Retortable and Microwavable Polypropylene is appreciated both for the mechanical properties it imparts to the fi lm and for its excellent temperature stability. These properties are particularly advanta- geous for instance in the manufacture of retortable or microwavable package. Polypropylene block copolymers PPC 2660 or PPC 3660 feature excellent mechanical properties as well as very high perforation resistance. In addition, both grades provide very high seal strength, which guaranties the seal integrity over the package shelf life. Films produced with PPC 2660 or PPC 3660 display high impact properties, which make them particularly suitable for lamination. PPC 2660 has a very high viscosity. This makes it suitable for blown fi lm. Like PPC 3660 it is a gel free material with good processability offering outstanding bubble stability on all kinds of blown fi lm lines that are properly equipped for processing polypropylene. Where a higher melt fl uidity is required PET tie layer particularly in cast fi lm production, AI
