The material proved the ideal container choice because it offered a unique combination of toughness, aesthetic appeal, wall thickness and chemical resistance. Firstly, as a copolyester it has a transparency rate of 91% - significantly higher than alternative plastics formulations. This gives the container high clarity, enabling full appreciation of the contents.

In addition, in order to keep the package robust as well as clear, the container can be made with thicker walls. This gives the polymer almost all the quality attributes associated with glass, without any of the drawbacks.
