Why do Polyurethane(PU) binder empower extraordinary performance for gravure lamination ink

The polyurethane binder plays a crucial role in the application of gravure lamination ink, offering extraordinary performance. Gravure lamination is a widely used technique for laminating films onto various substrates, such as paper, cardboard, or flexible packaging materials. The polyurethane binder acts as a key component in the ink formulation, providing essential properties and benefits.

 

Firstly, the PU binder offers excellent adhesion properties. It forms a strong bond between the film and the substrate, ensuring high-quality lamination with enhanced durability and resistance to peeling or delamination. This is particularly important to maintain the integrity of laminated products, such as food packaging or labels, throughout their lifetime.

 

Secondly, the polyurethane binder imparts exceptional flexibility to the laminated material. It allows the film to conform to the substrate's surface, even if it has complex shapes or contours. This flexibility is crucial for applications where the laminated material needs to withstand bending, folding, or stretching without cracking or compromising the overall integrity of the packaging.

 

Furthermore, the polyurethane binder enhances the abrasion resistance of the gravure lamination ink. It provides a protective coating on the laminated surface, shielding it from scratches, scuffs, or other mechanical damage. This is particularly important for applications that involve frequent handling, transportation, or storage, where the laminated surfaces are subjected to various external forces.

 

Moreover, the polyurethane binder offers excellent chemical resistance, preventing the laminated material from being affected by solvents, oils, or other potentially damaging substances. This makes it suitable for a wide range of applications, including packaging for cosmetics, pharmaceuticals, or industrial products that may come into contact with different chemicals.

 

Overall, the polyurethane binder in gravure lamination ink brings extraordinary performance by providing superior adhesion, flexibility, abrasion resistance, and chemical resistance. These properties significantly contribute to the durability, functionality, and aesthetic appeal of laminated materials, making them suitable for various industries and applications.
