‘bottle-eyeglasses’ design by suning chen from china

polyethylene terephthalate (PET) is one of the most commonly used food grade packaging
plastics due to it's chemical inertness and appealing physical properties. as with most
plastics PET is derived from oil and is formed by a polymerisation reaction between an acid
and an alcohol. its initial uses were as a synthetic fibre with excellent wash and wear
properties as well as a substrate for video, photographic and x-ray film. as its use grew
PET was modified for application in injection moulded and extruded products, and in the
early 1970's the first three dimensional structures were produced by blow moulding
techniques, initiating the rapid adoption of PET as a material for beverage bottles.
its properties as a lightweight, tough material with excellent optical properties and adequate gas
barrier performance for the retention of PET bottles are manufactured by the process
of injection stretch blow moulding (read more at http://www.bpf.co.uk) which was developed
specifically to maximise the beneficial properties of PET.
