Abstract
A system and method for controlling oxygen ingress in cap closures is disclosed. According to one embodiment, an apparatus includes a cap and a cap liner. The cap liner includes a first diffusive layer and a semi-diffusive layer. A first side of the semi-diffusive layer is adjacent to the first diffusive layer, where the semi-diffusive layer has a lower oxygen transmission rate than that of the first diffusive layer. The cap liner further includes a second diffusive layer, where a first side of the second diffusive layer is adjacent to a second side of the semi-diffusive layer, and the semi-diffusive layer has a lower oxygen transmission rate than that of the second diffusive layer. The oxygen transmission rate of the cap liner is controlled by varying a thickness of the semi-diffusive layer.
