To investigate the influence of tamper-evident band bridge strength on the opening properties of plastic closures. The relationship between the opening property of bottle caps and the band bridge strength was theoretically analyzed. Beverage bottle cap samples with three different bridge strengths of tamper-evident bands were prepared using specially designed forming tools. The opening properties of sample caps were evaluated by opening/breaking torque test, bridge strength test, and sampling experiment. As the strength of tamper-evident band bridges increased, both the opening torque and the break torque increased. Sampling experiment result showed that the sample closures with lower strength of tamper-evident band bridges (10-bridge design) achieved the highest acceptance rate of 93.2%. All sample caps with three different bridge strengths passed the online capping test. Tamper-evident plastic closures with reduced tamper-evident band bridge strength had better opening property.
