Application and requirements of glue cap machine in winery
Rubber caps are not only waterproof, moisture-proof, dust-proof, non-toxic and 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, rubber cap machine manufacturers Saiwei will introduce the rubber cap to everyone.
Most of the plastic caps at the beginning were tin-plated lead sheets, and the effect of tin-plating was to separate lead and 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. Because of the negative impact of lead on the environment. Now the plastic caps are generally 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% use aluminum caps. Although tinfoil caps dominate the 4 types of caps, tinfoil caps do not monopolize all the caps market. Winemakers will also, based on price, product features and image among consumers, Selectively use the other 3 types of rubber caps. Tinfoil caps score higher in product function and consumer image. The popularity of tinfoil caps is actually largely due to consumer product image: compared to the more expensive PVC , aluminum-plastic composite or aluminum cap, tin foil cap represents high quality.
Tinfoil caps are known for their smooth and seamless appearance and ease of use, and are 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 cap is different. Now, it is lithographic printing, and then formed on the wine bottle. The plastic cap made of flexible tin foil is easy to disassemble and not easy to wear, which is beyond the reach of aluminum foil plastic caps in the early stage.
The price of PVC (polyvinyl chloride) caps is better than the other 3 kinds of caps. PVC caps appear after tin foil and aluminum-plastic composite caps, and their main purpose is to meet customer requirements for low-cost caps. Only 10 cents, each aluminum-plastic composite bottle cap is 5 cents, and the average PVC bottle cap is only 3 cents, which can greatly save the packaging cost of popular wine. However, if the winery adds tear strips when ordering PVC bottle caps, the heat Foil or embossing, the cost of the cap will also increase (as does the aluminum-plastic composite cap).
PVC caps are very low in both "overall ranking" and "image ranking", but this kind of heat shrinkable cap with seams is very popular in many wineries because of its good 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 bottle caps have a place in the wine industry.
The above is all about the glue cap machine brought by Bian Xiao, I hope it will be helpful to everyone.
