Primary packaging of beer in plastics.
The paper reviews the requirements of beer packaging in relation to the properties of plastics, paritcularly as regards formability and good mechanical properties, heat resistance and stiffness, gas, moisture and aroma transmission. Plastics considered are polyethylenes, polypropylenes, polyvinyl chloride, polyesters, polystyrene and acrylonitrile. The fabrication of plastics is discussed with particular reference to orientation and its application to making of plastic beer bottles. The relative physicochemical properties of the various plastics considered to contain beer and other carbonated beverages indicate the distinct superiority of the acrylonitrile resins.
