For glass bottle packaging, tinplate caps are often used as the main seal. The tinplate bottle cap is more tightly sealed, which can protect the quality of the packaged product. However, the opening of the tinplate bottle cap is a headache for many people.
In fact, when it is difficult to open the wide mouth tinplate cap, you can turn the glass bottle upside down, and then knock the glass bottle down on the ground a few times, so that it will be easier to open it again. But not many people know about this method, so some people sometimes choose to give up buying products packaged in tinplate caps and glass bottles. This has to be said to be caused by the shortcomings of the glass bottle packaging. For glass bottle manufacturers, the approach has two directions. One is to continue to use tinplate bottle caps, but the opening of the caps needs to be improved to solve the problem of people’s difficulty in opening. The other is the use of spiral plastic bottle caps to improve the airtightness of glass bottles sealed with plastic screw caps. Both directions are focused on ensuring the tightness of the glass bottle packaging and the convenience of opening. It is believed that this kind of glass bottle capping method is popular only when these two aspects are taken into consideration.
