Processing Technologies
Plasma Surface Treatment

• Improvement of wettability of plastic surface
  The surface of various substrates, such as film, metal foil and nonwoven fabric is reformed to give surface hydrophilicity or repellency.

• Adhesion improvement of film surface
  Film surface reforming which is suitable for adhesive bonding, vapor deposition, and sputtering is performed at the customer’s request.

• Surface cleaning
  Organic contamination of substrate surface is removed to give clarified surface by plasma treatment.

• Bonding of heterogeneous materials
  Various materials are bonded by special plasma treatment without adhesive.
