Bio plastics are a large family of different materials, not just one material. They consist of a whole family of materials with different properties and applications. According to European Bioplastics, plastic materials are defined as bioplastics if they are bio-based, biodegradable or both.
HME offers many advantages over other pharmaceutical processing techniques. Molten polymers during the extrusion process can function as thermal binders and act as drug depots and/or drug release retardants upon cooling and solidification. Solvents and water are not necessary thereby reducing the number of processing steps and eliminating time-consuming drying steps. A matrix can be massed into a larger unit independent of compression properties. The intense mixing and agitation imposed by the rotating screw cause de-aggregation of suspended particles in the molten polymer resulting in a more uniform dispersion. The process is thus continuous and efficient.

> process flexibility, reduced downtime between batches and simple product changeover.
> dedicated screw profiles for homogenous mixing quality.
> Moderate shear and low shear stress without destroying delicate fillers.
> Using high-accuracy gravimetric feeders to introduce the raw materials into the twin screw extruder, which can reliably feed biomas with poor liquidity such as starch.
