Bottle caps come in a wide variety of types, with diverse materials and designs used in wine packaging.

Based on the molding method, bottle caps can be categorized into injection-molded caps and compression-molded caps.

Injection-molded caps are produced by injection molding machines：

some are formed in a single injection, while others are assembled from multiple injection molding processes. They are used in the packaging of products such as wine, cosmetics, and perfumes. Compression-molded caps are formed by machine pressing, typically made of aluminum or alumina, and were once a common material for high-end bottle caps.

By application, bottle caps can be categorized as wine bottle caps, water bottle caps, tea bottle caps, juice bottle caps, sterilizer bottle caps, etc.

By angle radius, bottle caps can be categorized as right-angle caps, rounded-corner caps, etc. In addition, some special-shaped caps are also available, with each shape meticulously handcrafted.

By color, bottle caps can be categorized as white, yellow, red, blue, etc. Essentially, any imaginable color can be produced.

Based on whether or not they have a sealing ring, bottle caps can be divided into one-piece caps, two-piece caps, etc.

All of these types of bottle caps can be used for packaging alcoholic beverages and other alcoholic drinks.
