Paper is becoming more and more important on the packaging industry as environmental friendly packaging is one of the levers that is taking more attention on industrial strategic plans. The crossover point between paper and board is normally considered to be around 160 to 200 grams per square meter (gsm). With a paper or board coating process, you achieve to have a product with specific features and benefits such as:

  • A better surface and/or improved visual appearance.
  • A glossy finishes that add interest to the package.
  • A barrier for water to reduce moisture.
  • Recyclability.

With an adhesive coating and laminating process with other material/s (other paper, solid board, film or aluminium foil) to sum different physical properties, the main features and benefits would be:

  • More resistance (weight, moisture…) to the package.
  • To have a release property by coating the paper with silicone. With these processes, you can have a great variety of pressure sensitive adhesive tapes or laminates used in the medical field or in industrial applications.
  • Enhanced appearance.
  • Food contact and preservation (barriers against moisture as well as oil and grease migrations…).

Besides coating, our lines can be equipped with other in-line processes such as embossing, printing, perforation, etc.
