Rubber caps are not only waterproof, moisture-proof, dust-proof, pollution-free, but also better protect the products in circulation. They are widely used in daily plastic products, ceramics, handicrafts, batteries and other industries. Today, the rubber cap machine manufacturer Saiwei is for Let's introduce the rubber cap:
Most plastic caps are tinned lead skins, and the effect of tinning is to separate the lead from the wine. By the early 1990s, this "lead cap" had been gradually screened out, not because of the effect of lead on wine, but because of the effect of lead on wine. This is because of the negative impact of lead on the environment. Today's caps are generally made of tin, aluminum, PVC plastic or aluminum-plastic composites. 55 percent of wineries use tin foil lids, 39 percent use PVC lids, and 32 percent use aluminum plastic Composite caps, 11 percent use aluminum caps. Although tinfoil caps dominate the 4 large caps, tinfoil caps do not monopolize the market for all caps. Winemakers also base the price, product features, and popularity among consumers image, and selectively use the other 3 rubber caps. The tin foil caps scored higher in terms of product function and consumer image. In fact, the popularity of tinfoil caps is largely due to the consumer's product image: compared with expensive PVC, Compared to aluminum-plastic composite or aluminum caps, tin foil caps represent high quality.
The tin foil cap is famous for its smooth and seamless appearance and easy to use. It is generally used for wine packaging. After a single cap is formed, it is first printed on the screen and then attached to the neck without any wrinkles at all; the aluminum-plastic composite cover is different. It It is printed by lithography and then formed on the wine bottle. The rubber cap made of flexible tin foil is easy to disassemble and not easy to wear, which is beyond the reach of the aluminum foil rubber cap in the early stage.
The price of PVC caps is better than the other 3 kinds of caps. PVC caps appear after tinfoil and aluminum-plastic composite caps, and their main purpose is to meet customer requirements for low-cost caps. Tinfoil caps cost 1 cent each, The aluminum-plastic composite bottle cap costs 5 cents per bottle, and the PVC bottle cap is only 3 cents on average, which can greatly save the packaging cost of popular wine. However, if the winery adds tear strips, hot foil or embossing when ordering PVC bottle caps, the bottle The cost of the cap will also increase (as will the aluminum-plastic composite cap).
