Is infrared drying suitable for printing on BOPP synthetic paper?

The application of infrared drying in the printing of BOPP synthetic paper is possible, but its applicability depends on several factors. The following is a detailed analysis of whether infrared drying is suitable for BOPP synthetic paper printing:

First, the basic principle of infrared drying

Infrared drying uses infrared radiation to heat the surface of the object, so that the water or solvent inside it quickly evaporates, so as to achieve the purpose of drying. Infrared radiation has the characteristics of strong penetration and high heating efficiency, so it is widely used in the paper industry and other fields.

Second, the characteristics of BOPP synthetic paper

BOPP (biaxially stretched polypropylene film) synthetic paper has the characteristics of high strength, high transparency, good tear resistance and moisture resistance. However, the surface is smooth and the adsorption of the ink is relatively poor, which may pose a certain challenge to the drying process.

Third, the applicability of infrared drying in BOPP synthetic paper printing

1.Drying efficiency: Infrared drying can rapidly heat the surface of BOPP synthetic paper and promote the evaporation of solvents in the ink, thereby improving drying efficiency. This is of great significance for improving production efficiency and shortening production cycle.

2.Surface quality: In the infrared drying process, the heat is mainly concentrated on the surface of the paper, and the influence on the inside of the paper is small. This helps to reduce problems such as paper distortion and curling, and maintain the surface quality of the printed matter.

3.Ink adaptability: Although infrared drying has good adaptability for most inks, in BOPP synthetic paper printing, special attention needs to be paid to the type and characteristics of the ink. If the ink contains ingredients that are sensitive to infrared radiation, it may speed up the drying process; On the other hand, if the ink is not sensitive to infrared radiation, it may be necessary to extend the drying time or use other auxiliary drying methods.

4.Safety: When using infrared drying equipment, strictly follow the operating rules to ensure the normal operation of the equipment and prevent safety accidents such as fire.

Fourth, precautions

1.Ink selection: When selecting inks suitable for BOPP synthetic paper printing, priority should be given to those ink types that are sensitive to infrared radiation to improve drying efficiency and quality.

2.Equipment configuration: The configuration of infrared drying equipment should be adjusted and optimized according to the actual production needs to ensure the best balance of drying effect and production efficiency.

3.Operation specifications: The operator shall strictly abide by the operation regulations and safety specifications to ensure the normal operation of the equipment and prevent the occurrence of safety accidents.

In summary, infrared drying is suitable for BOPP synthetic paper printing to a certain extent, but the specific effect needs to be comprehensively considered according to factors such as ink type, equipment configuration and production conditions. In practical applications, experiments and tests are recommended to determine the best drying scheme.
