Application and requirements of glue cap machine in winery
Rubber caps can not only effectively waterproof, moisture-proof, dust-proof, non-toxic and pollution-free, but also better protect products in the circulation process. They are widely used in daily plastic products, ceramics, handicrafts, batteries and other industries. Today The glue cap machine manufacturer Saiwei introduces us to the glue cap.
Most of the initial rubber caps were tin-plated lead sheets, and the function of tin-plating was to isolate lead and wine. By the early 1990s, this "lead cap" had been gradually selected, not because of lead The impact on wine is the negative effect of lead on the environment. Nowadays, plastic caps are generally made of tin, aluminum, PVC plastic or aluminum-plastic composite. 55% of wineries use tin foil plastic caps, 39% of wineries use PVC caps, 32% of wineries use aluminum-plastic composite caps, and 11% of wineries use aluminum caps. Although tin foil caps dominate the 4 types of caps, tinfoil caps are not the only glue that monopolizes everything. Caps market. Winemakers also selectively use other 3 types of caps based on the price of caps, product function and its image among customers. Foil caps score high in product function and customer image. In fact, the popularity of tin foil caps is largely due to the customer's product image: compared with the more expensive PVC, aluminum-plastic composite or aluminum caps, tinfoil caps represent high quality.
Foil caps are known for their lubricating, seamless appearance and ease of use, and are generally used in high-end wine packaging. The individual caps are first screen-printed after being formed, and then tightly attached to the neck without any wrinkles; aluminum plastic The composite plastic cap is different. It is first lithographically printed and then formed on the wine bottle. The plastic cap made of soft tin foil is easy to remove and does not wear easily, which is not achieved by the previous aluminum foil plastic cap.
PVC (polyvinyl chloride) caps are more expensive than the other three caps. PVC caps appear after tin foil and aluminum-plastic composite caps, and their main purpose is to meet customers' requirements for low-cost caps. Tin foil The plastic cap is 10 cents each, the aluminum-plastic composite plastic cap is 5 cents each, and the average cost of each PVC plastic cap is only 3 cents, which can greatly save the packaging cost of popular wine. However, assuming that the winery is ordering PVC When adding a tear strip, hot word foil or embossing, the cost of the rubber cap will also increase (the same is true for the aluminum-plastic composite rubber cap).
PVC caps are low in both "Overall Rank" and "Image Rank", but this 2-in-1, seamed, heat-shrinkable cap is popular with many wines because of its high quality and low price. Factory welcome.
The cost of aluminum-plastic composite caps is 45% lower than that of tin foil caps. Users' comments on the price of aluminum-plastic composite caps are second only to PVC caps. White's place.
