GB/T 4122.6-2010Packaging terms - Part 6: Printing (English PDF)

2.1 Packaging printing

To packaging materials, packaging products, label materials for the printing of the object printing.

2.2 Packaging printing process

In the packaging materials, packaging products, label materials to achieve the printing of a variety of norms, procedures and methods of operation.

2.3 Packaging Postpress process post-pressfinishingtechnology ofpackage

So that the packaging printed matter to obtain the required shape and performance of the production process.

Pretreatment of printing materials

3.1 Plasma treatment of

Through the discharge device will be ionized electrons or ions hit the substrate surface, open the substrate surface of the long molecular chain, while increasing the surface rough

Roughness to increase the adhesion of the substrate surface of the process.

3.2 Corona treatment

Belonging to a kind of plasma discharge, the use of high-frequency high voltage in the substrate surface discharge, so that the substrate surface oxidation and

To increase the surface roughness, in order to improve the adhesion of the substrate surface of the process.

3.3 Chemical treatment

The use of chemical solution as an oxidant, the substrate surface treatment, the substrate surface oxidation and polarization, increase the surface roughness

To improve the adhesion of the substrate surface of the process.

3.4 Photochemical treatment of

The use of ultraviolet light and other light source on the surface of high polymer printing materials, so that the molecules of cracking, crosslinking and oxidation, in order to improve the substrate surface

Adhesion of the process.

3.5 Coating treatment

The surface of the substrate coated with a strong adhesion of the material to improve the adhesion of the substrate surface of the process.
