This thermoplastic plastic (abbreviation for polyethylene terephthalate), which has been known since the 1930s, was further developed and made malleable in the 1960s. It is used to make bottles (PET bottles), films and textile fibres. The breakthrough came in 1978 when Coca-Cola marketed its branded drink in a 2-litre bottle made of this material. PET bottles ranging in size from 0.3 to 5.0 litres are in circulation. From the 1990s onwards, wines of a simpler design were also filled in PET bottles. Since the EU wine market regulation, which came into force in August 2009, the use of PET bottles is now also permitted for quality wines. The plastic is also used for the production of bag-in-box, Tetra Pak and capsules. Other plastics are GRP, polyethylene (PE), PVC and PVDC.
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.Andreas Essl
