How is the matte silver effect of PET matte silver label paper achieved?

The matte silver effect of PET matte silver label paper is mainly achieved through the following steps:

1、 Material selection

Substrate: PET (polyethylene terephthalate) serves as the main material for label paper, providing a foundation for high strength, water resistance, and chemical corrosion resistance.

Coating: Apply a special coating on the surface of PET substrate, which is the key to forming a matte silver effect.

2、 Printing process

Paint formulation: The main components of matte silver label printing paint include glue, pigment, and matte powder. Matte powder plays a crucial role here, making the printed label present a matte silver luster and texture.

Plate making: Produce a printed version based on the required patterns and textual information. Commonly used printing plates include screen printing, flexographic printing, and relief printing.

Printing: Apply the prepared printing coating evenly onto the plate effect, and then transfer the coating onto the PET substrate through the printing head of the printing machine. During the printing process, aluminum powder particles in the coating will be evenly distributed in the coating, reflecting sunlight or light sources such as street lamps, thus forming a matte silver effect.

3、 Post processing

Curing: After printing is completed, the label paper is dried, heated, and other treatments are applied to solidify the coating, enhance durability and waterproofness.

Cutting: Cut and trim the printed labels according to actual needs to meet the requirements of specific application scenarios.

The matte silver PET label paper not only has a beautiful matte silver effect, but also has excellent properties such as tear resistance, waterproofing, acid resistance, alkali resistance, abrasion resistance, and scratch resistance. Therefore, it is widely used in the label production of various products such as electronic equipment, mechanical equipment, household appliances, jewelry, etc.
