THERMO-FORMED DISPOSABLE TRAYS
A simple process of converting thermoplastic sheets into finished articles is called thermoforming. This is one of the oldest techniques employed, in which the process of heating sheets, between glass transition temperatures is by softening the point of the material in order to carve the material into the desired shape by using pressure/ vacuum. The process of thermoforming is restricted to relatively simple shapes having limited depth of draw. With this technique, it is possible to produce articles of less than 1mm of section thickness.
