GAS-BARRIER CORRUGATED FIBERBOARD

摘要

PROBLEM TO BE SOLVED: To prevent a metal from being used in a package to enable a metal detector to correctly detect whether abnormality is present on a content object when subjected to the metal sensor to monitor whether the object packaged with a corrugated fiberboard package is abnormal, and also to apply gas barrier properties to the corrugated fiberboard. SOLUTION: Gas-barrier corrugated fiberboard comprises a gas-barrier sheet 6 having a gas-barrier deposition thin film layer 2 bonded on one surface of corrugated fiberboard 9. The gas-barrier sheet 6 consists of a sheet including the deposition thin film layer 2 with a thickness of 5-100 nm and a gas-barrier coating layer 3 or the like laminated on at least one of surfaces of a basic material 1 made of a plastic or paper material.
