Thermoforming, also referred to as vacuum forming or deep drawing, is a highly economical process for manufacturing products such as trays, blister packs and cup lids in large quantities. In all cases, a flat plastic film or sheet is first heated and then pressurized air is applied or the sheet is shaped under vacuum to the contours of a forming tool. Three-dimensional moulded parts are created as a result, primarily for the packaging sector, but also for the toy, consumer goods and automotive industries as well as for many other sectors.
In principle, all thermoplastics are suitable for deep drawing, so that a suitable material – from commodities to high-performance plastic – is available for every application. FKuR meets the demand for biobased grades with Bio-Flex® PLA blends, a partially biobased PET and a biobased HDPE.
