Major Components
- Single-screw extruder, chosen based on the viscosity and processing requirements of the polymer which Melts and pumps polymer resin through a die to form a continuous film.
- Flat dies or T-dies are commonly used, depending on the application and desired coating width Ensures uniform distribution and layer thickness control.
- Coating Station The molten polymer is applied directly onto the paper substrate and Nip rollers ensure proper adhesion and thickness control of the coated layer. Chilling Rollers Immediately cool and solidify the polymer-coated paper to set the coating.
- Corona Treatment: Enhances adhesion by modifying the surface energy of the substrate and Improves bonding between the paper substrate and the polymer coating.
- Rewind System Collects the coated paper into finished rolls for further processing or distribution and Tension Control: Ensures uniform winding and roll formation.
Benefits
- Improves paper's strength, durability, moisture resistance, and barrier properties. customization of paper substrates for various applications in packaging and industrial sectors.
- Continuous process minimizes downtime and waste, enhancing productivity and cost-effectiveness. Supports the use of recyclable materials and enhances the recyclability of coated paper products.
- Effective barrier against gases and odors, maintaining product freshness and quality over extended periods. Resistant to various chemicals, ensuring the integrity of the packaged contents.
- Ensures uniform thickness and coverage of coatings across the substrate, maintaining product quality and consistency and Advanced control systems monitor and regulate key parameters to minimize defects and ensure reliable performance.
