Production of CPET sheets
Sheets made out of CPET (Crystalline Polyethylene Terephthalate) can be thermoformed into trays that are used in microwaves, conventional ovens, and in other applications where a high temperature stability is required (up to temperatures of 220°c). Applications for CPET trays made of DuFor materials are ready meals, airline trays and deep frozen meals. A typical CPET tray is made of a main layer in combination with a co-extruded top layer to allow sealing of a lidding film.
Toplayer for excellent sealing
For the production of high quality CPET trays, DuFor offers a complete range of raw materials. For example the CumaPET L04 065 top layer in combination with CumaPET E05 200 & CumaBatch 340 black main layer.
The combination of the above mentioned products will give you the following key characteristics in the end-product:
- Excellent high temperature stability (steam sterilisable)
- High impact resistance at deepfreeze temperatures
- High stiffness
- Food contact approved
- Good barrier properties
- Excellent chemical resistance
- Skeletal waste can be recycled in the main layer
