Title:
BARRIER LAMINATE AND PACKAGING CONTAINER
Document Type and Number:
Japanese Patent JP2023173877
Kind Code:
A
Abstract:
To provide a barrier laminate having a barrier base material having a gas barrier layer on an oriented polypropylene base material, the barrier laminate excellent in gas barrier property.SOLUTION: A barrier laminate at least includes a barrier base material and a sealant layer. The barrier base material at least includes: an oriented polypropylene base material at least having a first surface layer and a second surface layer; and a gas barrier layer disposed on the first surface layer. The oriented polypropylene base material is a polypropylene base material with an orientation treatment applied thereto. The second surface layer includes propylene homopolymer. The gas barrier layer at least includes a vapor-deposited film composed of a carbon-inclusive silicon oxide. An oxygen permeation degree of the barrier laminate after retort treatment by hot water for 30 minutes at 121°C under an environment at a temperature 23°C and a relative humidity 90%RH, measured in accordance with JIS K7126, is 3.0 cc/m2 day atm or less.SELECTED DRAWING: None
