Rubber caps are not only waterproof, moisture-proof, dust-proof, non-toxic and non-polluting, but also better protect the products in circulation. They are widely used in daily plastic products, ceramics, handicrafts, batteries and other occupations. Today, the editor introduced us to How to use and requirements of glue cap machine.

In the beginning, most of the rubber caps were tin-plated with lead, and tin-plated only separated the lead from the wine. In the early 1990s, this "lead cap" was gradually selected, not because of the effect of lead on wine, but because of the effect of lead on wine. Negative impact on the environment. Today's plastic caps are generally made of tin, aluminum, PVC plastic or aluminum-plastic composite. 55% of wineries use tin foil lids, 39% use PVC lids, 32% use aluminum-plastic composite lids, 11% Percentage uses aluminum caps. Although tinfoil caps dominate the 4 types of caps, tinfoil caps do not monopolize the market for all caps. Winemakers will also be selective based on price, product features and image among customers Use the other 3 types of caps. Foil caps score high on product functionality and customer image. In fact, the popularity of tin foil caps is largely due to the customer's product image: with more expensive PVC, aluminum-plastic composite or aluminum Compared with the cap, the tin foil cap represents high quality.

The tin foil cap is famous for its smooth appearance, seamless appearance and convenient use. It is generally used for wine packaging. After a single plastic cap is formed, it is first printed on the screen and then attached to the neck without any wrinkles. The aluminum-plastic composite cover is different. It is formed by lithography and then formed on the wine bottle. The glue cap made of soft tin foil is very easy to disassemble and will not be easily worn, which is not available in the early aluminum foil glue cap.

PVC (polyvinyl chloride) caps are better than the other 3 kinds of caps in price. PVC caps appear after tin foil and aluminum-plastic composite caps, and their main purpose is to meet customer requirements for low-cost caps. Tin foil bottle The cap is 10 cents per cap, the aluminum-plastic composite cap is 5 cents per cap, and the PVC cap is only 3 cents on average, which can greatly save the packaging cost of popular wine. However, if the winery adds tearing when ordering PVC caps Strips, hot foil or embossed printing, the cost of the cap will also increase (as will the aluminum-plastic composite cap).

PVC caps are very low in both "overall ranking" and "image ranking", but this kind of two-in-one, seamed heat-shrinkable caps are welcomed by many wineries because of their high quality and low price.

The cost of aluminum-plastic composite caps is 45% lower than that of tin foil caps. Users' evaluation of the price of aluminum-plastic composite caps is second only to that of PVC caps. It is precisely because of the advantages of capital that aluminum-plastic caps have a place in winemaking.
