The cap body and the anti-theft ring of the plastic anti-theft bottle cap are usually connected by a certain number of bridge points. Although these bridge points seem small, they are crucial to the anti-theft function of the bottle cap. Once the consumer unscrews the cap, these bridge points are broken and irreversible. If these bridge points are too thick, the pulling force will be very large, and it will be difficult for consumers to unscrew the bottle cap or even unscrew the entire cap body, resulting in a poor experience or the anti-theft function cannot be realized; The pulling force will become smaller, and these bridge points will break when the screw cap is filled, resulting in partial or complete separation of the cap body and the anti-theft ring and an increase in the reject rate.
In short, the impact of the bridge point on the plastic anti-theft cap is mainly reflected in the tensile value. The tensile value of the plastic anti-theft cap refers to the force required to separate the main body of the cap from the connection part of the anti-theft ring. This section of the technical lecture Guangzhou Yasu Packaging Technology Service Co., Ltd. will explain to you how to control and adjust the tension value of the plastic anti-theft bottle cap, so that it can not only meet the requirements of industrial production, but also ensure the opening feel of end consumers.
The connection bridge point of the bottle cap is determined by the ring cutting blade. The cutting edge of the ring cutting blade is relatively sharp and arc-shaped, usually with 8, 9, 12 or 16 notches evenly distributed. The blade is installed on the ring cutting machine and is completely fixed. The bottle cap rotates while revolving during the rotation process. The bottle cap rotates just one circle from the feeding of the knife to the output of the knife. The bottle cap completes the ring cutting process, and the gap position of the blade will form a bridge point.In this regard, our company has done very well. We have many years of production experience and superb technology. If you have any questions, please consult.
