Application of bottle caps
Bottle caps are an important part of food and beverage packaging, and are also the first place where consumers come into contact with products. Bottle caps have the function of keeping the contents of the product sealed, and also have the functions of anti-theft opening and safety. Therefore, they are widely used in bottled products. Therefore, bottle caps are the upstream industries of food, beverage, wine, chemical industry, and pharmaceutical industry, and are key products of bottle container packaging. In the early development of bottle caps, cork materials, tinplate crown caps and twist-off caps were used. So far, aluminum long-necked aluminum caps, carbonated beverage aluminum caps, hot-filled aluminum caps, injection aluminum caps, medicine caps, flip-open ring caps, safety button claw caps and plastic bottle caps have been developed.
Since bottle caps are an important part of the beverage packaging industry, the strong changes in the downstream consumer market demand will directly affect the market demand for bottle caps. The vigorous development of the beverage industry has higher and higher requirements for product packaging, which will drive the demand for bottle cap products. And bottle cap products occupy a key position in the beverage packaging industry, so the development trend of the beverage industry will directly affect the demand for bottle cap products. In recent years, the demand for bottle caps has been stable and growing, but the changes in packaging materials have caused changes in the structure of bottle cap products; overall, the use of plastic caps will increase. Although aluminum caps have been partially replaced by plastic caps, they are mainly used in wine and functional beverages, and the demand has grown steadily, while the demand for claw caps has changed greatly.
