Plastic Bottle Cap Mold

Plastic caps generally use polyolefin as the main raw material and are processed and formed by injection molding and hot pressing. Plastic anti-theft caps are required to be easy for consumers to open, and to avoid leakage due to poor sealing performance. How to properly control the sealing performance of bottle caps is the focus of online or offline testing by production units.

1. There is a circular leak-proof ring on the inner wall of the top of the general plastic cover; there are also ordinary plastic bucket covers that need to cooperate with the inner cover, so there is no need to design a leak-proof ring;
2. The lower end of the plastic cover is connected to an anti-theft ring through a tensile reinforcement;
3. At the same time, there are several pieces of sheet-shaped rotary tension wings evenly distributed on the inner wall of the anti-theft ring;

The plastic bucket lid designed in this way has the characteristics of firm sealing, leak-proof and anti-theft performance, safe and convenient use, can effectively prevent the liquid in the container from external pollution, and can ensure that various liquid product packaging meets national security standards.
