Material Characterisation

BMT use a custom-built (planar) biaxial tensile test machine to deform polymer samples at similar conditions to the stretch blow moulding process. Temperature, stretch ratio, strain rate and the mode of deformation can all be varied to fully capture the mechanical response of your polymer.

We provide bespoke offerings depending on your material requirements and can help when experimenting with new materials, recycled materials, materials with additives and more.

Preform Characterisation

BMT's preform characterisation service can comprehensively analyse any preform design, made from any material and using any process set-up. Using a custom-built blowing machine and high-speed digital imaging correlation, stress-strain data can be obtained directly from the blowing process.


This service is essential when experimenting with new materials and/or new preform designs. The benefits include increased knowledge of the  deformation behaviour, which can be translated into optimised product performance. 


BMT's simulation service is a bespoke consultancy offering which allows clients to engage in confidential projects. Together with our 20+ years of experience and our industry-renowned expertise in simulation, we understand that each bottle design commands different technical requirements. 

We provide comprehensive analysis of the deformation during stretch blow moulding and post-blowing (bottle performance), providing users with the data they need to optimise preform design, material selection and process set-up.
