Polypropylene is among the leading packaging materials which are widely used in Cast film extrusion. In recent years, PP cast films have gained market share in both traditional flexible packaging as well as non-packaging applications, e.g.
Typically these films are multi-material structures. Such multi-layer film solutions are of enormous advantage in optimising packaging performance, functionality and cost because they combine the properties of the different components in a synergistic way.
Product innovation is a continuous process due to the fact that the needs of customers as well as the environmental requirements are continuously changing. The mega trends in packaging are
Borealis offers a wide range of PP grades that are ideally suited for processing on cast film lines which are often used in combination with aluminium and other plastic films, including PET, PA and polyethylene (PE).
Our hetero-phasic (= block) copolymers incorporate an ethylene-propylene rubber during a separate phase of the polymerisation process, offering:
The high molecular weight block copolymers BB213CF, BA110CF and BC918CF are used in many different types of retortable food packaging – from soups and sauces to solid foodstuffs and pet food.
Our PP random copolymers, polypropylenes with statistically incorporated C2 monomers, offering:
Borealis´ PP homopolymers are available with different additive packages and as well with nucleation. These materials offer:
E.g. the high crystalline PP-homopolymer HD905CF is a suitable grade for hot fill applications, whereas the PP-random copolymer RE239CF is typically used in thick cast films as it provides excellent optical film properties and a low sealing initiation temperature.
As a leading supplier to the PP cast film industry for decades, Borealis can guarantee a reliable supply of high-performance materials for a variety of applications in advanced packaging. By working closely with our partners along the entire value chain, we keep discovering new ways to optimise packaging performance while at the same time delivering cost-efficient solutions to our customers.
