How to ensure consistency of thickness in PET matte silver paper production process?

In the production process of PET matte silver paper, ensuring the consistency of thickness is a key quality control link. This involves many aspects such as the precision of production equipment, the stability of raw materials, the control of production processes and quality testing. The following are some specific measures to ensure the consistency of PET matte silver paper thickness:

1. Select high-precision production equipment

Coating machine: Choose a coating machine with a high precision coating system to ensure the uniformity of the coating layer on the PET film. The high precision coating machine enables precise control of the thickness and distribution of the coating, thus providing a stable substrate for subsequent processing.

Vacuum aluminum plating machine: The use of advanced vacuum aluminum plating technology to ensure the uniformity and thickness of the aluminum plating layer. The stability and control accuracy of vacuum aluminizing machine have an important influence on the final thickness of PET matte silver paper.

2. Stability of raw materials

PET film: PET film with stable quality and uniform thickness is selected as the substrate. The quality of raw materials directly determines the final thickness and performance of the product.

Coatings and glues: Ensure batch to batch stability of raw materials such as coatings and glues to avoid thickness inconsistencies caused by fluctuations in raw materials.

3. Precise control of production process

Coating process: strictly control coating speed, coating pressure and coating flow and other parameters to ensure the stability of coating layer thickness.

Vacuum aluminum plating process: Optimize the process parameters of vacuum aluminum plating, such as aluminum plating time, aluminum plating temperature and vacuum degree, so as to obtain a uniform aluminum plating layer.

Composite process: On the wet composite machine, the composite pressure and speed of the PET matte silver transfer film and white cardboard are precisely controlled to ensure a good bonding between the two, while avoiding thickness changes.

4. Strict quality testing

Online testing: The thickness of PET matte silver paper is monitored and adjusted in real time by using online thickness testing equipment to ensure the stability and consistency of product thickness.

Sampling testing: Regular sampling testing of the produced PET matte silver paper, including thickness, gloss, adhesion and other performance indicators, to ensure that the product meets the quality requirements.

5. Continuous improvement and optimization

Data analysis: Collect and analyze the data in the production process, find out the factors that may cause the thickness inconsistency, and make targeted improvements.

Technological innovation: Constantly explore and introduce new technologies, new equipment and new materials to improve the production efficiency and product quality of PET matte silver paper.

In summary, to ensure the consistency of PET matte silver paper thickness needs to start from many aspects, including the selection of high-precision production equipment, to ensure the stability of raw materials, precise control of the production process, strict quality testing and continuous improvement and optimization of the production process. Under the combined action of these measures, PET matte silver paper products with consistent thickness and excellent performance can be produced.
