Excellent Application of Polyurethane Resin in Plastic Printing Ink

In today's printing industry, plastic printing inks play a crucial role. Among the many materials used in plastic printing inks, polyurethane resin stands out with its unique performance, making great contributions to the improvement of printing quality and the expansion of application fields.

1. Excellent Adhesion
   Polyurethane binder has excellent adhesion to various plastic substrates, whether it is common polyethylene, polypropylene, or engineering plastics, etc., it can be firmly combined to ensure that the printed pattern is not easy to peel off during use.
   For example, in the packaging industry, the products printed with the ink containing polyurethane resin still have a clear and complete pattern even after multiple handling and friction.
2. Good Flexibility
   It has good flexibility and can adapt to the deformation and bending of plastic materials under different conditions without cracking or falling off. This characteristic is particularly important in the printing of some plastic products with special shapes or foldable.
3. Chemical Resistance
   It has excellent chemical resistance and can resist the erosion of a variety of chemicals to ensure the durability of the printed pattern. In some application scenarios with more complex chemical environments, such as the printing of identification on chemical containers, polyurethane resin ink shows excellent stability.
4. High Glossiness
   It can endow the printed product with high glossiness, making the pattern more vivid and bright, and enhancing the visual appeal. In fields such as advertising printing and decorative printing, the advantage of this high glossiness has been fully exerted.

1. Flexible Packaging Printing
   In the field of flexible packaging such as food and medicine, polyurethane resin ink ensures the beauty of the packaging and the accurate transmission of information. Its excellent adhesion and chemical resistance guarantee the printing quality of the packaging during storage and transportation.
2. Plastic Container Printing
   It is used for the printing of various plastic containers, such as beverage bottles and cosmetic bottles. Good flexibility and glossiness make the patterns on the containers more attractive.
3. Printing of Plastic Components of Electronic Equipment
   In the electronics industry, plastic components often need printing for identification and decoration. The stability and high glossiness of polyurethane resin add a sense of refinement to electronic equipment.

In conclusion, polyurethane resin has occupied an important position in the field of plastic printing inks with its excellent performance. It has brought higher quality and broader development space to the printing industry and has become a key force to promote the continuous progress of plastic printing inks.
