  • Thermoforming

    Thermoforming THermoforming Thermoforming process produces plastic parts using heat, and later moulds use vacuum or pressure. It is inexpensive to manufacture blister packs, trays, and cup lids. A flat plastic film or sheet is heated during this process, followed by pressurised air. Sometimes the sheet is shaped under a vacuum. In the process, three-dimensional moulded…

  • Injection Moulding

    Injection Moulding Injection Moulding The injection moulding process is challenging when it comes to bioplastics. Earlier, the process was both expensive and incompatible. But over a period, as bioplastics evolved to replace traditional plastics, the technicalities improved, giving scope for injection molders to experiment with different bioplastics. Some bioplastics used for injection moulding include starch…

  • Blow Film Extrusion

    BLOW FILM EXTRUSION Blow Film Extrusion The Blown film extrusion process is used in the production of continuous films for packaging application. During the process, the bioplastic is melted in the extruder. The molten polymer enters the die head to form plastic tubes. In the case of multilayer films, there is a need for one…
