Specifications

Bottle cap torque force (bottle cap open and lock force) is one of the main factors affecting the sealing performance. Over torque force would bring great difficulties for open and winding up of bottle cup, and thus, reduce the convenience. Insufficient torque force would affect the seal performance of the container, and may further result in the leakage during transportation. Now, package design is designated to bring more convenience for fast consumption, and easy openness of bottle cap is one of the aims. When dealing such testing, GB/T17876-1999 is the standard, and craft-proof ring should be cut before testing.
 
The sealing performance of plastic bottle is the most important factor affecting package leakage and product deterioration. Excellent open easiness and sealing performance can be guaranteed through reasonable control of sealing performance and torque value. The barrier property of plastic bottles, including gas transmission quantity and water vapor transmission quantity, should also be controlled so as to guarantee the product quality during shelf-life period.
