Prototyping & Laboratory

Our experts support you in making sure your bottle and preform can optimally perform under real-world conditions.


It starts with the technical and commercial qualification of your PET bottle design, where we make sure your specifications are scrupulously respected


Once your PET bottle design is validated, we verify your mould. For this, COMEP studies and manufactures your pilot mould in order to conduct a blowing test. This mould validation goes from blowing of samples on a pilot mould to the testing of those samples (top load, thickness, section weights, main dimension checks). Samples can either be blown on COMEP premises or in your own factory. 


As a final step, the sample bottles are directly sent to you for your final technical and marketing validation.

Our flexibility enables us to complete these operations within a certain time frame, depending on your specific needs, in order to best fit your targets.
