The coating composition of PET thermal matte silver paper is mainly a uniform special coating, which is based on silverous polyester film (polyethylene terephthalate, PET) and is specially treated to give it matte silver effects and specific functional properties. However, regarding the specific chemical composition of the coating, the detailed formula is usually not disclosed due to the trade secrets and patent protection involved.
Function
The role of PET thermal matte silver coating is mainly reflected in the following aspects:
1.Matte silver effect: The coating makes the PET surface show the visual effect of matte silver, non-reflective, with a metallic texture and elegant silver luster, which enhances the aesthetics and sense of class of the label.
2.Thermal printing adaptability: The coating is specially optimized for compatibility with thermal printing technology, allowing PET thermal matte silver paper to respond quickly under thermal printers and produce clear images and text.
3.Durability: The coating enhances the properties of PET paper such as high temperature resistance, water resistance, oil resistance and scratch resistance. This allows PET thermal matte silver paper to maintain label clarity and durability in a variety of harsh environments.
4.Chemical stability: The coating also gives PET paper a certain chemical stability, so that it can resist the corrosion of chemicals such as acid and alkali, and extend the service life of the label.
5.Enhanced adhesion: Although the coating mainly acts on the surface of the PET paper, some coating treatments may also indirectly affect the adhesion of the PET paper to the adhesive layer, ensuring that the label is not easy to fall off after pasting.
Sum up
The specific composition of PET thermal matte silver coating varies by manufacturer and product, but its role mainly includes improving matte silver effect, enhancing thermal printing adaptability, improving durability and chemical stability. These characteristics make PET thermosensitive matte silver paper widely used in electronic products, automotive parts, medical equipment and other fields. It should be noted that due to the continuous development and innovation of coating technology, PET thermal matte silver paper produced by different manufacturers may have differences in coating composition and performance.
