The foundational technology for coating plastic bottles with Diamond-Like Carbon (DLC) thin films was co-developed by Kirin Brewery and Samco.
Our Diamond-Like Carbon (DLC) thin-film coating technology ensures superior preservation of flavor and aroma by providing an advanced barrier against oxygen and UV penetration, while effectively preventing contamination from plastic resins.
Furthermore, this advancement contributes to lighter container weight and reduced manufacturing costs.
This technology is currently utilized in food and beverage containers, with anticipated future applications in packaging for products such as beer, cosmetics, and pharmaceuticals.

Manufacturing Procedures

Discover the process for coating plastic bottles, such as PET, with DLC thin films. This technology enables plastic containers to achieve the superior quality preservation characteristics of glass.

  1. STEP01

    Evacuate the coating chamber to establish a high-vacuum environment.

  2. STEP02

    Fill the interior of the cylinder with acetylene gas.

  3. STEP03

    Utilizing high-frequency energy application to facilitate precise plasma generation.

  4. STEP04

    The decomposition of acetylene gas generates charged carbon and hydrogen ions.

  5. STEP05

    Carbon and hydrogen ions adhere to the inner wall of the bottle, forming a thin film.
