Title:
LID MATERIAL FOR PTP PACKAGING
Document Type and Number:
Japanese Patent JP2021008306
Kind Code:
A
Abstract:
To provide a lid material for a PTP packaging capable of reliably fluorescing with even a small amount of taggant pigment to discriminate authenticity.SOLUTION: A lid material 1 for a PTP packaging includes a light emitting layer 3 containing a taggant pigment 4 that fluoresces at a wavelength different from a wavelength of irradiated light, on one side or both sides of an aluminum foil layer 2, in which a thickness of the light emitting layer 3 is smaller than an average particle size (d50) of the taggant pigment 4. The light emitting layer 3 of the lid material 1 for the PTP packaging is irradiated with light of a specific wavelength, light fluorescently emitted from the taggant pigment 4 is visually detected and is detected by a detection device, and the authenticity can be determined by collating it with genuine data.SELECTED DRAWING: Figure 1
