Laser variable two-dimensional-code plastic composite package

Abstract

The invention relates to the field of laser anti-counterfeiting technologies and packages, in particular to a laser variable two-dimensional-code plastic composite package. The laser variable two-dimensional-code plastic composite package comprises a printed layer, an ink layer, a middle layer (which is only for a structure with two or more layers), and a thermally sealed layer from outside to inside, wherein ink is printed on the printed layer; the ink layer is used for forming patterns; the middle layer has barrier property and other functions; and the thermally sealed layer has the thermal bonding effect. The package disclosed by the invention has the advantages that a two-dimensional code is located on the inner side of the printed layer, cannot be wiped, and is hard to destroy, so that the uniqueness and the permanency of a product are guaranteed, and the anti-counterfeiting effect is achieved; no consumables and no damageable parts are used, and the package has an unmatchable cost advantage; and furthermore, the package is environment-friendly and pollution-free, and has a unique style which is different from the existing style.

Description

technical field [0001] The invention relates to the field of laser anti-counterfeiting technology and packaging, in particular to a laser variable two-dimensional code plastic composite packaging. Background technique [0002] At present, the unique code is the unique identification of the product. As an effective monitoring method in the process of product circulation, it was first widely used in the field of medicine. As one of the realization methods of the unique code, the variable two-dimensional code has become the preferred realization method in the field of composite packaging. Some industries are the first to use variable two-dimensional codes as monitoring methods, but they are mainly realized by labeling and transfer printing on the packaging surface. The traditional expression methods of two-dimensional codes are ink or transfer printing materials, which inevitably cause environmental damage. The disadvantage of pollution is that it is easy to be lost and wiped,...
