Alcohol in plastic ??
(OP)
Many food items are sold in plastic bottles and jars but
none of the alcohoic beverages -- as far I know.
Can anyone tell me why not ?

Bottles are now also done in some regions, at least for beer.
Main objections or problems revolved around permeability, which if insufficent, allows oxygen in and carbon dioxide out.
Oxygen in reacts with alcohol to make acetaldehyde then acetic acid, or vinigar.
Carbon dioxide out lets beer etc go flat.
For plastic bottles or film to be used, technology needed to be developed to get the required barrier properties at an economical price. In wine casks, this is done by metalising the film, with bottles it is done by co-extrusion with a barrier layer resin liker EVOH

Just go into any supermarket (in the US) and check out a large bottle of cheap liquor like Burnadetes Vodka (my favorite) or Vons Gin etc. They all come in plastic bottles now.
