How is the "matte silver" appearance of PET matte silver paper achieved?

The "matte silver" appearance of PET matte silver paper is mainly achieved through specific production processes and material formulations. Here's how to do it:

First, the production process

The production process of PET matte silver paper involves key steps such as coating and aluminum plating to achieve its unique matte silver appearance and performance. Taking the production of PET composite silver cardboard as an example, the production process roughly includes the following steps:

1.Coating: The PET film is coated by a coating machine to uniformly bond a coating layer on the PET film. This step provides the basis for subsequent aluminization operations.

2.Aluminum plating: Put the coated PET film into the vacuum aluminum plating machine, and vacuum aluminum plating is performed on the coating layer. Through vacuum aluminum plating technology, a uniform silver coating can be formed on the surface of PET film, which is the key to the appearance of PET matte silver paper "matte silver".

3.Composite: In the production process of some PET matte silver paper, it may also be necessary to compound the aluminized PET film with other materials (such as white cardboard) to further enhance its performance and use.

Second, material formula

In addition to the production process, the "dumb silver" appearance of PET dumb silver paper is also closely related to its material formula. For example, in the production of PET matte silver coating films, specific material combinations and additives are used to achieve matte silver effects. One possible material formulation includes:

Polyethylene terephthalate (PET) : As a substrate, it provides good physical properties and stability.

Deionized water: acts as a solvent to help regulate the viscosity and fluidity of the coating solution.

Defoamer: prevent bubbles in the coating process to ensure the flatness of the coating layer.

High temperature alumina: by forming a bumpy micro-rough surface on the surface of the coated film, forming diffuse reflection when the light is incident, so as to achieve the purpose of extinction, so that the PET matte silver coated film shows the appearance of matte silver.

Dispersant: Helps high temperature alumina and other additives to disperse evenly in the PET substrate.

Preservatives: Extend the shelf life and service life of the product.

Third, the realization of matte silver effect

Combined with the above production process and material formula, the "matte silver" appearance of PET matte silver paper is achieved. To be specific:

Vacuum aluminum plating technology: a uniform silver coating is formed on the surface of PET film, giving it a silver appearance.

Matting treatment: By adding a matting agent such as high temperature alumina, a slightly rough surface is formed on the surface of the coated film to achieve diffuse reflection effect, so that the PET matte silver paper presents the appearance of matte silver rather than bright silver.

In summary, the "dumb silver" appearance of PET dumb silver paper is achieved through a specific production process and material formulation. This unique appearance is not only beautiful, but also has good physical properties and durability, and is widely used in various fields.
