Title:
PAPER-PLASTIC PACKAGING MATERIAL HAVING PHOTON-SENSITIVE INK LAYER, PACKAGING CONTAINER, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/133855
Kind Code:
A1
Abstract:
Disclosed are a paper-plastic packaging material having a photon-sensitive ink layer, a packaging container made of the paper-plastic packaging material, and a method for manufacturing same. A photon-sensitive ink is coated on all or some localised areas of the outer surface of the paper-plastic packaging material, forming a photo-sensitive ink layer. The photon-sensitive ink layer is machined using a low power laser, such that some photon active material in the photon-sensitive ink layer changes in appearance and then forms a greyscale identifier, the surface of the greyscale identifier being smooth and having a greyscale difference from the surrounding area. In the process of manufacturing the identifier, since only a very low power laser is used to change the appearance of a photon active component in the photon-sensitive ink layer, without burning, etching or loosening the photon-sensitive ink, a packaging container made of this packaging material has a smooth aesthetic appearance and plays a very environmentally friendly role.
