High surface performance plastic printing material - PP synthetic paper

The in-mold label surface material is mainly composed of synthetic paper. Synthetic paper is a plasticized material. There is a difference in natural materials from the natural paper, which belongs to the category of plastic film. Synthetic paper has a wide range of applications. Some of its special properties, such as water resistance, grease resistance, and acid and alkali resistance, are not available in ordinary fiber paper and are widely used in packaging, decoration, advertising, and other fields. However, due to its own plastic properties: the surface energy is low, it basically does not have the adsorption of polar materials; the process is cast or biaxially stretched, the body is not a fiber tangled structure of paper, the porosity is low or not, Therefore, the ink permeability is poor. Its printing adaptability is very different from traditional paper and coated paper, and it has higher requirements for printing presses and printing inks.

We have solved the problem of surface treatment of polyolefins by introducing strongly polar hydrophilic groups onto the surface of the film. Since the graft chains are connected to the chemical bonds of the matrix film, this new surface is durable. On this basis, the company Developed high-performance surface coatings that fundamentally change the surface properties of existing plastics. The surface properties of the treated in-mold label paper are very stable, suitable for all kinds of printing methods, especially offset printing, which can achieve the effect of ordinary ink printing machine drying, greatly reducing the delivery time, ensuring the quality of printed products, reducing Printed version.

Our latest development of high surface performance plastic printing material - PP synthetic paper. At present, the most direct applications for this product are the printing industry and the packaging industry, and have completed two series of transparent films and opaque films and synthetic paper - self-adhesive surface substrate.

PP Synthetic Paper is a new type of environmentally-friendly plastic material product. In addition to the characteristics of both plastic and paper, the production process of synthetic paper is non-polluting. It can be recycled 100% and recycled. It is a major reform of modern paper production. Synthetic paper has a history of more than 30 years in foreign countries. The world sales of synthetic paper products are increasing at a rate of 10% every year. The pace of synthetic paper replacing some ordinary fiber papers is accelerating.

We apply a high adhesion coating on the surface of synthetic paper to make the printability of synthetic paper close to or reach ordinary paper. The surface coating consists of adhesives, fillers, functional additives, etc., which are in common with the materials used for paper coating. By controlling the proportions of the various components in the coating and the processing technology, the surface layer forms a certain degree of Porosity, to achieve the effect of absorbing ink, has good absorption and adhesion properties for oily printing inks, printing table dry speed, good adhesion firmness.

This technology is of great significance for the development of high-performance and functional film products and the expansion of plastic films and synthetic paper applications in the packaging industry and printing industry. This technology has complete independent intellectual property rights. After its promotion and application, it will enable future printing of film labels and self-adhesive materials on plastic substrates to be printed as easily as paper, and it can also solve the problem of high cost for small batch printing.
