Bioplastics and their applications
In search of new material solutions and proceeding an eye on the goal of sustainable production and consumption, bioplastics have various (potential) advantages. Advances in how they are produced is allowing bioplastics with controllable physical properties to be produced enabling uses which mimic those of oil-based plastics. The properties of some bioplastics allow novel functions to be carried out.
Bioplastics can also be processed in very similar ways to petrochemical plastics such as injection moulding, extrusion and thermoforming. To improve their tensile strength, bioplastic polymers can be blended with their co-polymers or with other polymers.
Current end-use segments of bioplastics –

- Shopping bags
- Compostable waste collection bags
- Trays and Punnets for vegetables, fruits, meat and eggs.
- Disposable catering servicewares
- Medical applications
- Implants such as screws, pins or plates
- Material for pills and capsules
- Mulch films
Non-Biodegradable and durable products –
- Automotive interiors like seats, head rests or arm rests
- Mobile phone cases
Emerging end-use segments of bioplastics –
- 3D printing
- Metalized Biaxial oriented -PLA films for food packaging
- Baby products – Toys and Teethers
- Modified PLA for durable applications – Interiors and under the hood automotive parts
