The United States designed and produced pull-top caps

In order to facilitate the feeding of infants and medication for the elderly, the development of heat-sensitive color packaging is also increasingly important. A thermosensitive color-developing packaging material can be made by injecting a thermosensitive chemical element into PE. Packaging containers made from this packaging material will show different colors when they are served at different temperatures. Consumers only need to look at the color of the package to determine if the food is suitable for consumption. In the past, food packaging containers were often tightly packed for the sake of sealing performance. They were extremely inconvenient and open and destructive. The food must be eaten in time after opening. With the improvement of the process and the updating of materials, the easy-to-open and easy-to-seal packaging containers have been rapidly developed with their ease of use. On the one hand, past tinplates were replaced with easy-openable and easy-to-seal materials such as composite plastic films, aluminum plates, etc.; on the other hand, past cans and closures were replaced with cans, ziplock Bags, easy-open cans, and rotating glass bottles. Glass bottles. In addition, at present, in order to meet the requirement that athletes drink without having to stop during exercise, a packaging company in the United States has designed and produced a pull-type bottle cap that is designed to have a suction mouth and clamp it. On the bike's water bottle clip shelf allows consumers to drink while cycling.
