WebAug 1, 2008 · Two methods are generally used to produce a sustained stress on the bottle to determine the container’s resistance to ESCR. In the constant-top-load test, a fixed weight is applied to each bottle. This test method, also known as the P&G test (named for Procter & Gamble), mimics the stress encountered from a stack of multiple cartons. WebWhile the PET bottles provide safe transportation and storage of soft drinks, occasional cracking of the petaloid base presents problems to the manufacturers of the PET bottles. In this study, dimensions of the petaloid shaped base are optimized against stress cracking by means of finite element analysis (FEA) and process simulation software.
