UNI E-TPS

UNI E-TPS is an enhanced type of TPS/ synthetic polymer compound which has increased mechanical and physical properties compared to common TPS based PP and PE compounds. It is stronger and also has more transparency also much cheaper nearly as much as normal non-degradable polymers.

To date, many biodegradable polymers are available, namely, polylactic acid (PLA), polyhydroxybutyrate (PHB),and etc. Even so, in some cases, the high cost of producing biodegradable polymers prevents them from being used as substitutes for traditional polymers. An attractive alternative to the development of biopolymers is the use of natural raw materials such as starch. Starch is an abundant, plant-based biodegradable material with interesting physicochemical characteristics that can be exploited, and this has received attention for development of TPS products. However, starches exhibit some limitations mostly related to mechanical properties, thermal stability, and humidity absorption. Because of these limitations, starches are often blended with other materials to enhance their properties. Blending starches aims to reduce the production cost; to improve barrier properties and dimensional stability; to decrease the hydrophilic character of starch; and increase its biodegradability. 

Recently, the demands for biodegradable and renewable materials for packaging applications have increased tremendously. This rise in demand is connected to the growing environmental concerns over the extensive use of synthetic and non-biodegradable polymeric packaging, polyethylene in particular.
