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

The production process of PET thermal matte silver paper is a complex and delicate process that mainly involves steps such as raw material preparation, coating, drying, compounding (if applicable), cutting and packaging. The following is a general production process:

1. Prepare raw materials

PET substrate: Select a high-quality polyethylene terephthalate (PET) film as the substrate to ensure its excellent physical and chemical properties.

Thermal coatings: Prepare special coatings suitable for thermal printing, which are capable of chemical reactions when heated to reveal images and text.

Matte silver treatment materials: Special materials prepared to be used to achieve matte silver effects, perhaps by adding specific ingredients (such as matting agents) or using special processes.

Adhesive: Select an adhesive with good adhesion and removability for attaching the label paper to the target object.

2. Apply

Thermal coating: Use a coating machine to evenly coat the thermal coating on the PET substrate to form a thermal coating. During the coating process, the coating amount and coating speed need to be precisely controlled to ensure the uniformity and quality of the coating.

Matte silver treatment coating: The matte silver treatment material is coated on the thermal sensitive coating, and the surface of the label paper is presented with matte silver effect through a special process. This step may involve a multi-layer coating and drying process to ensure the stability and durability of the matte silver effect.

3. Dry

The coated PET thermal matte silver paper is sent to the oven or drying equipment for drying treatment to remove solvents and moisture from the coating, allowing the coating to cure and adhere to the PET substrate. The drying temperature and time need to be adjusted according to the type and performance of the paint.

4. Compound (if applicable)

If it is necessary to produce composite materials (such as the composite of PET with other materials), it is necessary to perform composite treatment on PET thermal matte silver paper after drying. This usually involves using composite adhesives to bond PET thermosensitive matte silver paper to other materials such as paper, film, etc.

5. Cutting and packing

The finished PET thermal matte silver paper that is dried and compounded (if applicable) is cut to the desired size and shape. This can be achieved by die-cutting, slitter and other processes.

After the cutting is complete, the PET thermal matte silver paper is packaged to protect it from contamination and damage. Packaging methods may include roll packaging, sheet packaging, etc.

It should be noted that the specific production process may vary from manufacturer to manufacturer. Some manufacturers may adopt more advanced production processes and equipment to improve production efficiency and product quality. In addition, with the continuous development of technology, the production process of PET thermal matte silver paper is also constantly optimized and improved.

In general, the production process of PET thermal matte silver paper is a complex process involving multiple steps and links, which requires strict control of the process parameters and quality standards of each link to ensure the quality and performance of the final product.
