The production and manufacturing process of PET thermosensitive matte silver paper is a complex and delicate process, mainly including the following steps:
1、 Material preparation
PET substrate: Select PET (polyethylene terephthalate) film with a certain thickness and strength as the substrate. PET film has good chemical stability and physical properties, making it an ideal material for making matte silver paper.
Thermal sensitive coating: A thermal sensitive coating prepared for coating, which is mainly composed of various chemical substances such as colorless dyes, colorants, sensitizers, stabilizers, adhesives, etc. These components can undergo chemical reactions under heating conditions, releasing colors.
2、 Coating and aluminum plating
Coating: Send the PET film into the coating machine for adhesive treatment to uniformly bond a layer of coating on the PET film. This step provides a foundation for subsequent aluminum plating operations.
Aluminum plating: Vacuum aluminum plating is performed on the PET film after adhesive coating to form a uniform layer of aluminum. This step is the key to achieving the unique matte silver appearance of PET thermosensitive matte silver paper.
3、 Drying and solidification
Drying: After coating and aluminum plating are completed, the PET film is sent to a drying equipment for drying treatment. The purpose of this step is to firmly attach the coating to the PET film and achieve the best printing effect.
Curing: The PET film is cured by heating or ultraviolet irradiation to further enhance the adhesion and durability of the coating.
4、 Subsequent processing
Cutting and slitting: Cut and slitting the dried and cured PET thermosensitive matte silver paper according to requirements for subsequent use and processing.
Quality inspection: Conduct quality inspection on PET thermal matte silver paper after cutting and slitting, including checking the clarity, color, flatness, firmness, etc. of the labels.
Packaging and Storage: Pack qualified PET thermosensitive matte silver paper and label and store it according to customer requirements.
5、 Environmental Protection and Safety Production
Throughout the entire production and manufacturing process, it is necessary to closely monitor environmental protection and safety production issues. Strictly abide by relevant environmental regulations and safety rules, take effective measures to reduce the discharge of pollutants such as wastewater and exhaust gas, and ensure the safety of production equipment and operation processes.
In summary, the production process of PET thermosensitive matte silver paper includes multiple steps such as material preparation, coating and aluminum plating, drying and curing, subsequent processing, and environmental protection and safety production. These steps together ensure that the quality and performance of PET thermosensitive matte silver paper meet customer needs.
