Abstract:

The packaging requirements for barrier properties are not even able to be achieved with polymers in monolayers based on crude oil. For both conventional and bioplastics a co-extrusion or the lamination of different polymers is the key to fulfill these requirements of today’s packaging applications. Of course, it is still questionable if such high barriers are necessary but achieving such levels is state of the art in packaging technology. In order to enter new markets and increase the range of applications for bioplastics these resins must follow this trend and need to be co-extruded or laminated.
