The main technical features of synthetic paper and its application in the field of labels (below)

Fifth, the application of synthetic paper

As PP synthetic paper has the characteristics of both plastic and paper, it has a wide range of applications in many aspects, mainly in the following three aspects: 1. High-quality printing. Such as posters, pictorials, pictures, maps, calendars, books, etc. Especially in water-resistant printing newspapers, off-site advertising, etc. appear to be more rational. 2, packaging purposes. Such as handbags, packaging boxes, pharmaceutical packaging, cosmetics packaging, food packaging, industrial product packaging. 3, special purpose. Such as film labels, pressure sensitive labels, thermal labels, banknote paper, color paper, tracing paper for CAD, industrial computer and instrumentation paper, express envelopes, clocks, plates, paper fans, umbrellas, travel paper hats And other travel promotional items.

Six, surface modification of synthetic paper and plastic film

The above-mentioned synthetic paper is a base paper of a direct production line without any treatment. Its basic performance is mainly surface or plastic properties. Synthetic paper and plastic film materials are increasingly used in industrial and real life applications. However, many polymers have inherently poor surface properties, poor surface hydrophilicity, dyeability, and biocompatibility. Their application in some fields. The polymer surface modification technology can enable the polymer to maintain its own properties while maintaining surface properties that are different from the bulk properties. Therefore, the polymer surface modification has attracted more and more attention. In order to better adapt to different fields of application, more professional and higher requirements have been put forward for the surface treatment technology of synthetic paper.

Our company has been working on the surface treatment and application development of synthetic paper and plastic film for many years. At present, we can modify the surface of most plastic films to make it a new multifunctional plastic film material that is easy to bond, easy to write, and easy to print. At present, the most direct applications of this product are: printing industry and packaging industry; and two series of transparent films and opaque films and synthetic papers have been completed.

Synthetic paper is a plastic material, and there is a difference in natural materials and natural paper, belongs to the category of plastic film. For a long time, the technical difficulties in the printing process have not been solved well, and the printing quality is not stable. The company introduced strong polar hydrophilic groups on the surface of the film, and the new surface was durable due to the chemical bonds of the graft chains to the matrix film. On this basis, the company developed a high-performance surface coating. Fundamentally change the surface properties of existing plastics. 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, which will make printing of film labels in the future, printing of self-adhesive materials on plastic substrates as easy as paper, and also solve the problem of high printing costs in small batches. The surface properties of the treated paper are very stable and suitable for various printing methods, especially offset printing. Synthetic paper has a wide range of applications. Some special properties of synthetic paper, such as water resistance, moisture resistance, corrosion resistance, grease resistance, acid and alkali resistance, and insect resistance, are not available in ordinary fiber paper and can be widely used for label printing and packaging. , decoration, advertising, etc., but due to its own plastic properties: the surface energy is low, basically does not have the adsorption of polar materials; the processing process is cast or two-way pulls, the body is not a paper fiber entanglement structure, pores The rate is low or absent, so 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.

Our coating on the surface of synthetic paper with a high adhesion coating makes the printability of synthetic paper close to or reach ordinary paper. The coated synthetic paper and plastic film materials have properties closer to natural paper. The surface coating consists of adhesives, fillers, functional additives, and other components. Control the proportion of each component in the coating and the processing technology to form a certain porosity in the surface layer to achieve the effect of ink adsorption. It has good absorption and adhesion properties for oily printing inks. The printing surface has fast drying speed and adheres firmly. Good degree.

Synthetic paper is a new type of environmentally friendly plastic material product. The production process is non-polluting and can be recycled 100%. It is a major reform of modern paper production. The pace of replacing synthetic fiber paper with synthetic paper is accelerating. Moreover, non-paper plastic labels need to be resistant to water in frozen products, and have advantages and environmental protection in some special fields such as moisture-proof.
