This study investigated the strength retention and reliability of glass bottles through accelerated life tests in the presence and absence of chemical strengthening and hot end coating (HEC). Forced contact was induced by rotation up to 5000 times using a line simulator. As the number of rotations increased, the strength and lifespan of the untreated glass bottles gradu-ally decreased. However, the number of chemically strengthened bottles was higher than that of untreated bottles. As the accelerated tests progressed, variations in impact strength were observed. In addition, the Weibull modulus, an indicator of reliability, was affected by the treatment. The survival probability of the glass increased from 0 to more than 90% when chemical strengthening was applied. Therefore, the chemical strengthening of the glass containers had an excellent life-extension effect, even in the absence of HEC.
