Abstract
A barrier plug having a spout body to be attached to a container, and a cylindrical molded article inserted into the spout body, wherein the cylindrical molded article has a resin layer having a barrier resin, an oxygen transmission rate of the resin layer is 10000 mL·μm/m2·24 hrs·MPa (23° C. and 65% RH) or less, a water vapor transmission rate of the resin layer is 1000 g·μm/m2·24 hrs (38° C. and 90% RH) or less, and the cylindrical molded article forms a discharge flow path for discharging contents in the container to an outside.
Claims8
A barrier plug comprising a spout body to be attached to a container, and a cylindrical molded article inserted into the spout body, wherein
- the cylindrical molded article comprises a resin layer comprising a barrier resin,
- an oxygen transmission rate of the resin layer is 10000 mL·μm/m2·24 hrs·MPa (23° C. and 65% RH) or less,
- a rate of decrease in the oxygen transmission rate of the resin layer is 80 to 100% at 23° C. and 65% RH compared to 23° C. and 90% RH,
- a water vapor transmission rate of the resin layer is 1000 g·μm/m2·24 hrs (38° C. and 90% RH) or less, and
- the cylindrical molded article forms a discharge flow path for discharging contents in the container to an outside.
