FKuR Launch Transparent Flexible Biopolymer

FKuR has launched a new transparent, flexible biopolymer. Called Bio-Flex F 2201 CL this material contains a high content of renewable resources and, in line with the other resins in the Bio-Flex family, can be processed easily on standard LDPE blown film lines and converting equipment.

With a renewable resource content of approximately 60 % this grade is a consistent further development of the Bio-Flex family. Its mechanical properties exhibit a high elongation and flexibility along with good puncture resistance. Consequently Bio-Flex F 2201 CL can ideally be used to adjust the properties of all the available Bio-Flex family resins. However, due to its good interply strength, Bio-Flex F 2201 CL is recommended to be used as a mid-layer in a co-extruded structure. As a result of its mechanical properties it is the perfect partner for Bio-Flex A 4100 CL in a transparent 3-layer combination. Bio-Flex A 4100 CL is a clear but stiff material with properties comparable to PP.

The combination of these two transparent grades offers superb and unmatched clarity for a biodegradable blown film available today while maintaining a very high content of renewable resource material. This is between 60 - 80% depending on the variation of polymers of the final structure. As both polymers are clear, the transparency of a 20¦Ìm film, for example, is close to 91% (light transmission figure). The toughness and high tear resistance are the result of the core Bio-Flex F 2201 CL layer and the renewable content of a 20 micron 3-layer structure with a layer ratio of 20 / 60 / 20 (%) is around 70%. Using such a structure, this film is ideal for VFFS applications.

FKuR Kunststoff GmbH will be presenting this application and other innovative products at Interpack D¨¹sseldorf, booth F 14 hall 9 from May 12th - 18th.

Bioplastics are a unique class of material which are based on renewable resources or which enable the biodegradability of products made from these polymers.
