PET matte silver label paper is mainly composed of the following materials:
1.PET substrate: This is the main part of the label paper, made of polyethylene terephthalate (PET). PET is a polymer material with excellent physical and chemical properties, such as high strength, high transparency, heat resistance, cold resistance, and chemical corrosion resistance. These characteristics make PET an ideal material for making label paper.
2.Matte silver coating: A layer of matte silver coating is usually applied on the surface of PET substrate. This coating not only gives the label paper a silver white metallic luster, but also gives it a matte texture, reducing reflection and improving the visual effect and readability of the label. The matte silver coating can also enhance the wear resistance and scratch resistance of the label.
3.Adhesive: Adhesive is the key component that connects the label paper to the adhesive surface. It is usually a pressure-sensitive adhesive that can quickly adhere and firmly adhere to the surface of an object under pressure. The type and performance of adhesive have a significant impact on the adhesion and durability of labels.
4.Bottom paper: The bottom paper is the supporting part of the label paper, usually used to protect the adhesive and prevent it from being contaminated or damaged during storage and transportation. When printing or pasting labels, the backing paper can be torn off, exposing the adhesive and label content.
In summary, PET matte silver label paper is mainly composed of PET substrate, matte silver coating, adhesive, and backing paper. The selection and combination of these materials determine the performance and application range of the label paper.
