Efficient Application Process for Optimal Results

Applying SENDA’s heat-seal coatings is straightforward and designed to integrate seamlessly into both high-speed production lines and smaller-scale operations. Follow these steps for the best results:

Before applying the heat-seal coating, ensure that all materials are properly prepared:

  • Clean the Surfaces: Make sure the paper or substrate is free of dust, oils, and other contaminants that could interfere with adhesion.
  • Check Compatibility: Verify that the materials are compatible with SENDA’s heat-seal coatings to ensure optimal bonding.

Using the right equipment is crucial for an efficient application process:

  • High-Speed Production Lines: Utilize automated applicators or coating machines designed for large-scale operations. These machines can evenly apply the coating at high speeds.
  • Small-Scale Operations: For smaller batches, manual application using brushes, rollers, or spray systems is effective.

Apply the heat-seal coating using one of the following techniques, depending on your operation scale:

  • Automated Coating: Set the applicator to the recommended settings to ensure an even layer of coating. This method is ideal for high-volume packaging.
  • Manual Coating: For smaller applications, use a brush or roller to spread the coating evenly over the surface. Ensure the layer is consistent to prevent weak spots.

Once the coating is applied, proceed with the sealing process:

  • Heat Application: Apply heat to the coated surfaces using a heat sealer or press. For optimal results, maintain the temperature between 120°C and 160°C.
  • Pressure Application: Use the appropriate amount of pressure to ensure the coating adheres firmly to the substrate. This is particularly important in high-speed lines to maintain consistent quality.

Allow the coated materials to cure properly to achieve a strong bond:

  • Quick Curing: SENDA’s heat-seal coatings cure rapidly, typically within 1 to 2 seconds at sealing temperatures.
  • Cooling Period: After curing, let the sealed products cool down to room temperature. This usually takes less than 5 seconds and solidifies the bond, ensuring durability.

Inspect the sealed products to ensure they meet your quality standards:

  • Check Seals: Verify that the seals are uniform and free of defects. Look for any gaps or weak spots that could compromise the package integrity.
  • Test Bond Strength: Conduct peel or tensile tests to assess the bond strength and ensure it meets the required specifications.

By following these steps, you can effectively apply SENDA’s heat-seal coatings to achieve optimal sealing results. Whether operating on a high-speed production line or managing smaller batches, our coatings offer reliable performance and efficiency, enhancing the quality and sustainability of your packaging solutions.
