What is the production process of PET thermosensitive matte silver paper?

The production process of PET thermal matte silver paper involves several steps, mainly relying on key technologies such as coating, aluminum plating, composite and stripping. The following is a typical PET thermal matte silver paper production process:

First, the main production equipment

Coating machine: Used to evenly coat the surface of PET film with a specific coating or glue.

Vacuum aluminum plating machine: Vacuum aluminum plating on coated PET film to form matte silver effect.

Wet composite machine: the PET film after aluminum plating is combined with white cardstock or other substrates.

Rewinding machine: After the composite is completed, the PET film is stripped to obtain the final PET composite silver cardstock.

Second, the production process

1.Gluing steps:

Feed the PET film into the coater.

A specific coating or glue is evenly applied to the surface of the PET film to form a coating layer. This step is to prepare for subsequent aluminization and composite.

2.Vacuum aluminum plating steps:

The coated PET film is fed into the vacuum aluminizing machine.

In a vacuum environment, aluminum plating is performed on the coating layer of PET film to form a matte silver effect. This step is the key to the unique look of PET thermal matte silver paper.

3.Compound steps:

In the wet composite machine, the aluminum coated PET film (matte silver transfer film) and white cardstock or other substrates are released at the same time.

The aluminum layer of the matte silver transfer film is coated with water-based composite adhesive.

The matte silver transfer film is bonded together with white cardstock or other substrate composite. This step ensures a strong bond between the PET film and the substrate.

4.Stripping and rewinding steps:

On the rewinder, the PET film is stripped.

The PEtted PET film and the substrate (such as white cardboard) have been firmly combined to form PET composite silver cardboard.

The PET composite silver cardstock is rewound for subsequent cutting, slitting and packaging processes.

In summary, the production process of PET thermal matte silver paper is a complex process involving multiple steps and key technologies. Through fine process control and high-quality material selection, high quality PET thermosensitive matte silver paper products can be produced.
