The production process of PET matte silver paper involves several steps, which together ensure the quality and performance of the final product. The following is an overview of a typical PET dumb silver paper production process:
1. Raw material preparation
PET film: As a substrate, PET film needs to have good physical and chemical properties to meet the requirements of subsequent processing and use.
Matte silver coating material: Usually includes pigments, adhesives, dispersants and other components used to create a matte silver effect on the surface of PET films. These materials require precise proportioning to ensure uniformity and stability of the coating.
2. Coating process
Gluing: First, the PET film is sent to the coating machine for gluing treatment. The purpose of gluing is to uniformly bond a coating layer on the surface of the PET film to provide a adhesion basis for the subsequent matte silver coating.
Matte silver coating: The coating layer is coated with matte silver coating material. This step requires precise control of parameters such as coating volume, speed and temperature to ensure uniformity and thickness consistency of the matte silver coating.
3. Curing treatment
Drying and curing: After coating is completed, the PET matte silver paper needs to be processed in the drying and curing equipment. Through heating and ventilation, the solvent in the matte silver coating evaporates and the adhesive solidifies, thus enhancing the adhesion and durability of the coating.
4. Surface treatment (optional)
According to product requirements, it may also be necessary to perform surface treatment on PET matte silver paper, such as embossing, frosting, etc., to further enhance its matte silver effect and touch.
5. Cutting and rewinding
Slitting: The cured PET matte silver paper is slitted according to the specified size to obtain the width of the finished product that meets the requirements.
Rewinding: The PET matte silver paper after cutting is rewound for easy storage and transportation.
6. Quality inspection
In all aspects of the production process, strict quality testing is required to ensure that the quality of PET matte silver paper meets the standard requirements. Test items may include coating thickness, uniformity, adhesion, chemical resistance, scratch resistance, etc.
7. Packaging and shipping
Finally, the qualified PET matte silver paper is packaged to prevent damage during storage and transportation. Then deliver the goods according to the order requirements.
It should be noted that the production process of different manufacturers and equipment may be slightly different. The above process is only a typical example, and may need to be adjusted according to specific conditions in actual production.
In addition, with the progress of technology and changes in market demand, the production process of PET matte silver paper is also constantly optimized and innovative. For example, some manufacturers may use more advanced coating technology and equipment to improve production efficiency and product quality; Or develop new matte silver coating materials to meet the needs of specific applications.
