Today let's talk about mineral water plastic bottle caps

Today, let's talk about mineral water plastic bottle caps. Although it is very inconspicuous, its market sales cannot be ignored by bottle cap manufacturers. For some newly built plastic bottle caps, there will be many problems from raw materials to assembly in the process of blowing mineral water plastic bottle caps. We will talk about it in detail today.

First of all, we suggest that it is best to use two kinds of low-pressure materials, 5000S and 7042, for mineral water caps. Other low-pressure materials are prone to cracks in mineral water bottles. In addition, mineral water plastic bottle caps will also crack during the assembly process. At this time, it is necessary to find the reasons from the following aspects: First, the quality of PP material is directly related to the quality of the finished product, and the secondary material mineral water bottle cap is easy to break. Secondly, uneven capping machine capping is prone to cracks. Thirdly, there is a unified standard for the mouth of mineral water bottles. If the diameter of the lid and the mouth of the bottle are not standard, it is easy to cause cracks. Next, when pressing the cap, whether the temperature in the bottle cap assembly room is too low, the temperature is too low, and the lid is easy to break. Then, whether the process in the bottle cap production process meets the requirements. Finally, the mineral water plastic bottle cap cylinder is too long, and the cap cylinder is easy to crack when the cap is pressed.
