Bottle Caps (candy) Bottle caps are used to seal the openings of
bottles of many types. For
glass bottles they are small circular pieces of
metal with
plastic backings, and for plastic bottles a plastic cap is used instead. A bottle cap is typically colorfully decorated with the
logo of the brand of beverage. Plastic bottle caps are often made of a different type of plastic than the bottle itself, and may not be
recyclable.
