3. Interpretation of the core content of the standard

a) Substrate classification and application cases

Substrate is the basis of packaging and printing materials. According to the material properties, it can be divided into paper, plastic, metal, etc. For example, coated paper is often used in food packaging because of its excellent waterproof and barrier properties.

b) Technological evolution of printing inks

Printing inks can be divided into relief, lithography, gravure, etc. according to the process properties. In recent years, UV digital printing inks have become an industry trend due to their environmental protection and high precision.

c) Innovative application of surface finishing materials

Surface finishing materials, such as lamination and glazing, significantly improve the protective performance of packaging. For example, radiation-cured varnish is widely used in high-end packaging.
