Why does 7030 pigment foil adhere firmly?

7030 pigment foil is a decorative material that has been carefully designed and specially processed. It has been widely used in the fields of packaging printing and decorative materials for its unique metallic luster, rich color selection and excellent adhesion performance. Whether it is the decoration of high-end gift boxes, exquisite labels, or various composite film products, 7030 pigment foil can provide satisfactory decorative effects.

Surface modification is a crucial link in the production process of 7030 pigment foil. Its main purpose is to change the chemical and physical properties of the pigment foil surface to improve its compatibility and adhesion with the paper and composite film surfaces. Through surface modification, a layer of film with special functions can be formed on the surface of the pigment foil. This film can form a good combination with the microstructure of the paper and composite film surface, thereby enhancing the adhesion effect.

The surface modification of 7030 pigment foil is mainly carried out by combining chemical methods and physical methods. The chemical method involves treating the surface of the pigment foil with specific chemical reagents to change the chemical properties of its surface. These chemical reagents can react with the active groups on the surface of the pigment foil to form new chemical bonds, thereby improving its adhesion properties. Physical methods mainly include plasma treatment, electron beam irradiation, etc. These methods can change the microstructure of the pigment foil surface, improve its surface roughness and activity, and thus enhance its adhesion to paper and composite films.

The surface properties of the 7030 pigment foil after surface modification have been significantly improved. The modified pigment foil surface has higher activity and can more easily form chemical bonds with the surface of paper and composite films, thereby improving adhesion. The modification treatment can also improve the wettability of the pigment foil surface, making it easier to be wetted and spread by the coating liquid, further improving the adhesion effect. Surface modification can also improve the weather resistance and chemical resistance of the pigment foil, so that it can maintain a stable decorative effect under various environmental conditions.

Coating technology is another key process in the production process of 7030 pigment foil. Its main purpose is to evenly coat the pigment foil on the surface of paper or composite film to form a continuous and uniform decorative layer. Through coating technology, it is possible to ensure that the pigment foil forms good adhesion on the surface of paper or composite film while maintaining its unique decorative effect.

The coating technology of 7030 pigment foil is mainly based on the rheological properties, wettability and film-forming properties of the coating liquid. The coating liquid is usually composed of pigments, resins, solvents and additives, which are carefully proportioned and mixed to form a coating liquid with specific properties. During the coating process, the coating liquid is evenly coated on the surface of paper or composite film through the coating head, and then dried and cured to form a solid decorative layer.

Key elements of coating technology
(1) Ratio of coating liquid: The ratio of coating liquid is one of the key factors affecting the coating effect. The ratio of pigments, resins, solvents and additives needs to be carefully designed and adjusted to ensure that the coating liquid has suitable rheological properties, wettability and film-forming properties.

(2) Selection of coating head: The type and specification of the coating head also have an important influence on the coating effect. Different coating heads are suitable for different coating requirements and material types. Choosing a suitable coating head can ensure that the pigment foil is evenly and continuously coated on the surface of paper or composite film.

(3) Control of coating process: Control of coating process is also an important link to ensure the coating effect. Parameters including coating speed, coating pressure, drying temperature and time need to be precisely controlled and adjusted to ensure the quality and performance of the coating layer.

The decorative effect of 7030 pigment foil treated by coating technology has been significantly improved. First, coating technology can ensure that the pigment foil forms a continuous and uniform decorative layer on the surface of paper or composite film, avoiding defects such as mottled and cracked. Secondly, coating technology can also improve the adhesion and wear resistance of pigment foil, making it less likely to fall off or wear during use. Finally, coating technology can also be customized according to customer needs to meet the decorative needs of different products.

The special process treatments such as surface modification and coating technology used in the production process of 7030 pigment foil do not exist in isolation, but are interrelated and interact with each other. Surface modification provides a good foundation for coating technology, making it easier for the coating liquid to wet and spread on the surface of the pigment foil; and coating technology further consolidates the effect of surface modification, ensuring that the pigment foil forms good adhesion on the surface of paper or composite film. This combined effect makes 7030 pigment foil have excellent adhesion performance, decorative effect and weather resistance, meeting customers' demand for high-quality decorative materials.
