PET 
                      Containers used in :- 
                     PET can be semi-rigid to rigid, depending on its thickness, 
                      and is very lightweight. It makes a good gas and fair moisture 
                      barrier, as well as a good barrier to alcohol (requires 
                      additional "Barrier" treatment) and solvents. 
                      It is strong and impact-resistant. It is naturally colorless 
                      and transparent.
