1. Compression cap replaces the injection cap

Although compression molding is a new process that has only emerged in the past 10 years, it has given a strong challenge to the 100-year-old traditional injection molding process and has achieved overwhelming advantages. At present, the plastic-molded caps account for more than 80% of Coca-Cola, Pepsi, Unity, and Master Kong; Wahaha's tea beverages and soft drinks, Huiyuan PET juices and so on have reached 100%. Compression molding and lidding technology accounted for 70% of the global share, accounting for more than 60% of China's share. Since 2001, Chinese customers have purchased more plastic caps and closures injection equipment than plastic caps and closures injection molding equipment.

2. The use of single-piece caps and short caps has gradually increased

Since 2002, the world's petrochemical raw materials have generally risen in price, while the price of plastic cap and closure has instead decreased, therefore, people are more stimulated to seek updated technology to reduce costs. In order to better reduce costs, people have focused their attention on the top of PET bottles, shortening the bottle mouth to become their favorable measure. The Coca-Cola Company first implemented the 1881 bottle standard in China, and the number of monolithic lids and 1881 plastic caps gradually increased.
