Packaging applications polyvinylchloride

Polyvinylchloride (PVC) films have found wide applications in the packaging of a large variety of foodstuffs, such as fresh meat, fruits and vegetables, and cheeses [1]. These commercial films, in addition to the polymeric component, contain a number of additives. The one used in the highest proportion is the plasticiser. 

While the polyvinyl acetate-based emulsions have multiple applications (office glues, wood glues, packaging industry, etc.), the acrylic emulsions are used mainly for the production of autoadhesive films and tapes or for other labels (see PSAs part) their main value therefore lies in the large variety of formulations accessible (using variable composition copolymers) and in the good tolerance they demonstrate toward the plasticizers present in certain substrates (bonding of polyvinylchloride films for example). 

Some Pebax grades are used to enhance the characteristics of other thermoplastics, in particular as antistatic agents, since they naturally disperse electrostatic charges, and as such can be added to a large number of thermoplastic matrices (acrylonitrile-butadiene-styrene (ABS), polystyrene, polyoxy-methylene (POM), polyvinylchloride (PVC), polymethylmethacrylate (PMMA) and polycarbonate (PC)) to impart permanent antistatic properties, whatever the ambient relative moisture or surface friction they may be subjected to. These antistatic compounds are suitable for countless applications in office and electronic equipment (photocopier components, printer components, etc.) as well as in technical packaging,...
