Embodiment Construction

[0028] The technical means adopted by the present invention to achieve the intended invention purpose are further described below in conjunction with the drawings and preferred embodiments of the present invention.

[0029] figure 1 Shown is a perspective view of a composite packaging material according to an embodiment of the present invention. The composite packaging material 2 has a plurality of units 1 for forming a single package. 1 in each unit figure 1 Variable codes 13 and identification codes 19 are printed on different layer structures in the area indicated by the middle letter A. The variable codes 13 and identification codes 19 of each unit are unique, that is, the variable codes 13 and identification codes 19 of any two units are different from each other. In addition, the relative position description from top to bottom in the layer structure of the composite packaging material involved in the present invention corresponds to the relative position description ...

Abstract

The invention provides a packaging sheet group. The packaging sheet group comprises a plurality of sheets which are made of a composite packaging material, wherein each sheet is a unit for forming independent package, the sheet is provided with a base layer, a printing layer and a waterproof layer from inside to outside, each sheet is provided with only one variable code which is covered by a scraping ink layer, a variable ink layer is further arranged above the scraping ink layer, and only one identification code can be formed by the variable ink layer under laser radiation. One visible identification code and one invisible variable code are arranged on the same position of each sheet, and are used for associating information with different attributes, so that the product packaging function is enriched while limited space of the product packaging surface is sufficiently utilized.

Description

technical field [0001] The present invention relates to a packaging sheet set, in particular to a packaging sheet set for liquid beverage packaging. Background technique [0002] Liquid foods such as milk, yogurt, and semi-liquid foods such as juice are usually sold in small volume packaging containers. Such packaging containers are formed from a continuous roll of packaging material that can be slit to form blanks, or sealed longitudinally to form tubes of packaging material, which are then sealed and formed while filling the contents, and finally sealed at the folding process. The bits are folded into the shape of the final package. For liquid or semi-liquid food, current packaging containers are made of paper-based composite packaging material with a paper fiber core surrounded by one or more layers of barrier material, such as a polymeric coating and / or metal film to obtain composite packaging materials. The barrier material serves to protect the core material from co...
