Polyurethane coated roller for packaging machinery

The polyurethane coated roller for packaging machinery is a functional component based on a metal roller core, with the surface covered in polyurethane elastomer. It is primarily used in high-precision bonding processes for films and substrates. Its core characteristics include:

       ‌Superior Physical Properties: Wide hardness range (Shore A50-D80) with adjustable properties, combining high elasticity (rebound rate ≥95%) and tear resistance (30-60 kN/m), capable of withstanding high-pressure bonding and high-speed operation conditions.

       2. Superior Surface Performance: The rubber surface is finely smooth with strong adhesion, ensuring a uniform coating with no bubbles or wrinkles.

‌       3. High chemical stability: Resistant to oils and solvents (such as fountain solution, UV inks), compatible with various adhesives and film materials.

       4. Long-lasting Durability: Wear resistance 3-5 times that of rubber, composite vulcanization technology ensures adhesion strength ≥12MPa, preventing adhesive failure. These roller bodies are precision-machined to achieve ±0.02mm dimensional tolerance and are suitable for -40℃ to 120℃ environments, widely used in the coating process of packaging equipment for food, pharmaceuticals, etc.
