Category: Plastic screw caps

Bottle cap, Bottle top

Plastic closures for the top opening of a plastic bottle commonly made from PE (HDPE #2) or PP (#5). Caps for plastic bottles are often made of a different type of plastic from the bottle.

Plastic caps may have a pour spout. A “sports cap”, which appears on many water bottles, allows water to pass around the central blue piece. A cap is sometimes colourfully decorated with the logo of the brand of contents.
