PACKAGING MATERIAL AND PACKAGE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a packaging material with improved unsealability while keeping sealability by providing a cut on the packaging material mainly comprising paper, and to provide a press-through-packaging(PTP) package wherein an article such as a tablet received in a package using the packaging material as a lid can be easily removed and further an injury in such an accident that the whole package is erroneously taken can be prevented. SOLUTION: A cut is made to the middle of its depth on a packaging material mainly comprising paper, whereby the material is made to be easy to unseal with sealability of the package kept by applying force to the cut to push to tear. The cut is formed by a laser beam.
