Glass adds an element of class to any product. Consumers will pay more per price point for glass because it gives a certain sophistication to almost every item packaged with it. For instance, food, cosmetics, olive oils, beverages, jams/jellies, mayonnaise and hot sauces are packaged in glass bottles and jars. Have you ever bought wine in a plastic container, or how about a six-pack of plastic beer bottles? Plastic tends to give the impression that the product being packaged is cheaper or of lower quality. http://www.finspotglass.com/glass-lotion-bottle/
