High barrier closure liner with oxygen absorbing capabilities |
abstract |
In order to provide a liner which can be used in place of existing type liners used in a closure for a container, a multiple layer liner sheet is coextruded in a manner wherein the outer layers are skin layers formed of a gas permeable material. These layers enclose a gas barrier layer and a foamed layer which respectively prevent the invasion of oxygen from the ambient atmosphere and remove oxygen from the head space to safeguard the contents of the container. The foamed layer provides the liner with the required resiliency, provides space for the inclusion of an adequate amount of oxygen scavenging material, and also provides a cellular structure which allows the gas molecules the freedom to move and quickly come into contact with the oxygen scavenging material. As the gas barrier layer is formed of a material which does not readily become permanently attached to the material from which the foam layer and skin layers are formed, tie layers of adhesive are formed on either side of the gas barrier layer to ensure integrity when the coextruded sheet is formed into individual liners. |
