Title:
PLASTIC SHEET WITH GRAYSCALE IDENTIFICATION AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/113755
Kind Code:
A1
Abstract:
Disclosed are a plastic sheet and a manufacturing method therefor. The plastic sheet at least comprises a substrate and a photon-sensitive ink layer arranged at the surface of one side or both sides of the substrate, wherein the photon-sensitive ink layer locally or fully covers the surface of the substrate; a grayscale identification is formed in the photon-sensitive ink layer; the grayscale identification is an image formed after the change in the appearance of a part of a photon active material in the photon-sensitive ink layer; and the surface of the grayscale identification is smooth and has a grayscale difference from a peripheral region. During the manufacturing of the grayscale identification, the appearance of a photon active ingredient in the photon-sensitive ink layer is changed by using a low-power laser machine; and the photon-sensitive ink is not burned, etched or has not fallen off, such that the plastic sheet and a package manufactured from the plastic sheet have a smooth appearance.
