[null,null,null,"Sommario/riassunto","Plastics have developed into the most important class of packaging materials. Their relative impermeability for substances from the surroundings has great influence on the shelf life and the quality of the packed goods. At the same time the interaction between the contents and the various components of the packaging plays a decisive role.This particular book is indispensable in the search for the optimal plastic packaging. It facilitates the estimation of the influence on the goods which come from the surroundings and from the packaging. The authors do not restrict themselves only to the d"]
