BARRIER PLUG AND CONTAINER WITH BARRIER PLUG Russian patent published in 2021 - IPC B65D75/58 B32B7/02 

FIELD: polymeric products.

SUBSTANCE: invention relates to a barrier plug and to a container with a barrier plug. The barrier plug has an outlet adapted to be attached to a container, and a cylindrical molded article inserted into the outlet, the cylindrical molded article having a resin layer containing a barrier resin, the oxygen permeability of the resin layer is 10,000 ml·μm/m2·24hours·MPa (at 23 ºC and 65% relative humidity) or less, the permeability of the resin layer to water vapor is 1000 g·μm/m2·24 hours (at 38 ºC and 90% relative humidity) or less, the degree of reduction in oxygen permeability of the resin layer is 80 to 100%, the melting point of the barrier resin is higher than the melting point of the resin constituting the outlet element, the thickness of the resin layer is 25-700 μm, the barrier resin contains vinylidene chloride copolymer or ethylene-vinyl alcohol copolymer, and a cylindrical molded product is configured to form an outlet flow channel for discharging the contents in the container outside.

EFFECT: use of barrier resin in plug and container manufacturing.
