Nano-multilayer FilmPICASUS™

Nano-multilayer Film PICASUS™

A film that makes use of Toray's proprietary nano-lamination technology to express metallic luster without using metal.

PICASUS™ is a film that uses Toray's proprietary nano-lamination technology to express metallic luster without using metal. It has an extremely high level of formability and can also be integrally molded with resin. Since it is free of metal, it has functions such as electromagnetic wave transmission, and can be used as a substitute for plating, coating, etc., contributing to a reduced environmental impact. It is ideal for decoration of smartphones, PCs, home appliances, and more. Additionally, various design expressions are possible in combination with processing such as surface treating and printing.

Free of metal but has the texture of metal

PICASUS™ uses Toray's proprietary nano-lamination and polymer technology to produce a metallic luster without using metal.

Toray's unique optical design technology creates nano-graded multilayer structures with a high level of precision. Interference reflection in the visible light spectrum achieves a natural metallic luster without using metal.

Light permeability

The film is metallic while having excellent light permeability, making new designs combining LED and LCD possible.

Electromagnetic wave permeability

High electromagnetic wave permeability enhances the design freedom of electrical and electronic components without interfering with the antenna functionality of communication devices.

Excellent formability

Toray's unique polymer design and polymerization process technologies have resulted in PICASUS™, with a new polymer metallic luster and dramatically improved interlayer adhesion and formability. This makes the film applicable for various forming techniques, including insert molding, hot press molding, and vacuum pressure molding.

Decoration molding and processing methods

Insert Molding

  1. A hard coating, protection film, decoration (print), and binder are laminated on PICASUS™ to finish the decorative film.
  2. The decorative film is preformed through hot press molding or vacuum pressure molding.
  3. Unnecessary parts are trimmed.
  4. It is set in the injection mold.
    The resin is poured in, integrally molding the decorative film with the resin.

Panel Processing

  1. It is possible to print on either one or both sides of PICASUS™.
  2. Adhesion with glass or plastic sheets is possible.

Application Examples

Flat screen TVs

The high level of designability makes it possible to differentiate designs of flat screen TVs. Electromagnetic wave and light permeability help improve the designability of the IR sensor section.

Home materials

Since the film can be used for IR sensors, light receiving parts such as water taps can be finished with a flat design and metallic luster. Additionally, it can be used for various types of plated or mirrored panel switches.

Household appliances

PICASUS™ has excellent electromagnetic wave permeability, allowing it to be used for touch switches in home appliances. Additionally, unprecedented designs can be achieved by utilizing the metallic luster and light permeability of the film. There is no better material for improving the design and functionality of future smart appliances.

Future interfaces

Thanks to its electromagnetic wave and light permeability, direct projection on items is possible where normally a mirror would be required, and it can also be used with touch panels. It has great expectations as a next-generation film that will bring to life the interfaces of the future, such as digital signage with interactive functionality, touch panel desks with mirrored tones, etc.

Notebook PCs / laptops

The high electromagnetic wave permeability makes it ideal as decoration for areas where communication performance are a concern, and it can also be applied to capacitive touch pads, etc.


In recent years, smartphones and tablets have increasingly been adorned with decorative films to accommodate diverse designs. PICASUS™ contains no metal and has excellent formability and radio wave permeability, making it a candidate for further expanding the freedom of design in the future. It is also compatible with capacitance switches and wireless charging, making it an ideal material for higher functionality.


Improving design and promoting lighter weight and less metal-reliant vehicles. Application development of decorative films continues to expand thanks to the diversification and multi-functionalization of interiors. PICASUS™ allows for a whole new level of expression.
