Characterization and production of agglomerated cork stoppers for spirits based on a factor analysis method

The decision-making in the investment of a new line stoppers based on agglomerated cork requires knowledge composition and its contribution to performance. For this, it is necessary observe leading products market test series prototypes with different formulations. development manufacturing made by cork, such as bottle stoppers, benefits strongly from accurate chemical structural characterizations, correlated final material A wise starting point fulfill requirement consist comparing available be compared varying composition. This work presents blind characterization samples through non-supervised exploratory analysis designed select corks for spirits still wines packaging industry. total 18 batches, 3 them being high-end commercial products, were used build 15 prototypes. They subsequently characterized exact microgranulated unknown variable. Statistical results 14 parameters related physic-thermo-mechanical properties indicate that suitability selecting stopper relies study only 4 or 5 initial parameters. Hence, shown reduced number may considered properly describe mechanical behavior allowing choice most convenient intended application. factorial map reveals sample batch manufactured tested correlates three supplied competence.
