Polyurethane resin is a polymer compound generated by the reaction of polyisocyanate and polyol, which can provide good flexibility, adhesion, wear resistance, oil resistance, water resistance and acid and alkali resistance, and also has a certain high temperature resistance and good gloss. It is a kind of excellent connection material with various excellent properties. Therefore, polyurethane resin is widely used in flexographic printing inks as a connection material for film printing inks. Flexographic printing ink is a special ink for flexographic printing, usually used to print packaging materials, such as cartons, cardboard, paper and plastic bags, food packaging, labels, newspapers, catalogs, etc. Flexo printing inks are characterized by low cost, environmental protection, clear printing effect, bright colors, and can be printed on a variety of materials.

There are many types of flexographic printing inks, and the common ones are as follows:

1. Water-based flexographic ink: Water-based flexographic ink is an environmentally friendly ink, it uses water and other solvents as diluents, does not contain harmful substances, harmless to the human body and the environment. Waterborne flexographic ink has good printing performance and is suitable for all kinds of flexographic printing presses.

2. Solvent-based flexographic inks: solvent-based flexographic inks use organic solvents as diluents, with better printing performance and printability, but because the solvent is harmful to the environment and human body, it is necessary to pay attention to safety when using.

3. Thermal transfer flexographic ink: Thermal transfer flexographic ink is a new type of ink, which can transfer printing patterns to flexible materials through thermal transfer technology, with high printing effect and durability.

In general, flexographic printing ink has a variety of types and characteristics, according to different printing needs and material requirements, the choice of suitable resin flexographic ink can improve the printing quality and efficiency. The polyurethane resin as the connection material of film printing ink, can provide good flexibility, adhesion, wear resistance, oil resistance, water resistance and acid and alkali resistance, but also has a certain high temperature resistance and good gloss, is an excellent performance of the connection material.
