We have developed a transparent and highly flexible film that contributes to reducing environmental impact through high biomass content and biodegradability. This film is modified polylactic acid (PLA) using our unique technology, maintaining transparency while achieving both flexibility and heat resistance. Additionally, its softness and excellent moldability help suppress whitening during folding processes. 【Features】 ■ Provides flexibility to normally rigid polylactic acid (PLA) ■ Contributes to reducing environmental impact with over 95% high biomass content and biodegradability ■ Can be utilized for packaging that takes advantage of visibility ■ Improves heat resistance from around 60°C to over 100°C *For more details, please download the PDF or contact us directly.

An anti-fouling film for marine organisms is a special film that has properties that make it difficult for marine organisms such as barnacles, crustaceans, mollusks, and algae (fouling organisms) to adhere in the ocean. By applying it to areas where marine fouling organisms are problematic, such as measuring instruments used in the ocean, marine sports equipment, fishing gear, boat bottoms, seawater intake areas, and structures where anti-fouling paint is difficult to apply, it becomes harder for fouling organisms to attach, and any minor adhesion can be easily wiped off, making maintenance easier. Additionally, since it has an adhesive film structure, you can choose between a strong adhesive type suitable for long-term use where peeling would be problematic, or a re-peelable type that can be applied and removed as needed, depending on the application.

"Custom-made system" that supports the development and contract processing of films tailored to customer specifications. Utilizing our film manufacturing technology (T-die method) in a clean environment and our long-cultivated fine shape surface molding technology from the production of prism sheets, we can form microchannel patterns designed by customers on the surface of thin films ranging from 100μm and above, contributing from prototyping to mass production in a roll-to-roll manner. Not just cover films for microchannel chips! Leave the prototyping and mass production of the microchannel body to us!

Transparent engineering plastic cyclic olefin film (COP) excels in heat resistance, transparency, low UV absorption, low impurity characteristics, non-adhesiveness, chemical resistance, high moisture barrier properties, and low dielectric constant and low dielectric loss characteristics compared to other transparent plastic materials, and it also has good vacuum formability. These properties make it promising for use in optical films, bio-related films, medical packaging materials, and electronic components such as antenna substrates. Heat-resistant COP is ideal for electronic substrates. We manufacture non-stretched films from cyclic olefin resin pellets according to user specifications. Please feel free to inquire about resin grades, widths, thicknesses, and more.

Not only can it be erased! Our whiteboard screen film, treated with a special surface processing technology, prevents indoor fluorescent lights from reflecting when taking smartphone photos after meetings. Additionally, during projection with a projector, the light source does not reflect, allowing for a clear view from any angle. Furthermore, we offer magnet types that can be attached to blackboards or steel partitions in meeting rooms, as well as adhesive types that can be placed anywhere.

- Very flexible and can be applied/wrapped freely. - It does not lift even when applied to curved surfaces or corners. - Thanks to the tackiness of the elastomer, it can be adhered to objects without adhesive. It is also easy to peel off and reapply. - The surface has a moderate grip feel, providing anti-slip properties. - Since antiviral agents are blended into the resin, it has a longer-lasting effect compared to coating types.

- Acrylic resin-based sheet with excellent thermal conductivity and electrical insulation properties - Silicone-free, does not generate low molecular siloxanes that can cause contact failure - Top-class heat resistance temperature of 130°C as an acrylic thermal dissipation sheet - Available in double-sided adhesive type W and single-sided adhesive type S, allowing selection based on application - Customization is possible to meet your needs. Please feel free to contact us.

"Custom-made system" that supports the development and contract processing of customer-specific films. Our unique technology has made it possible to create nano-sized patterns on the surface of extruded films. By selecting nano-patterns and extruded resins suitable for specific purposes and applications, the potential of nano-pattern films has expanded compared to conventional UV imprint films. It is expected to be useful in applications related to biotechnology, electronics, and optics. We encourage you to utilize our technology in your company's new product development. 【Features】 - Capability to create nano-sized patterns on the surface of extruded films - The ability to select nano-patterns and extruded resins suitable for specific purposes and applications expands the possibilities of nano-pattern films compared to conventional UV imprint films.

○ Sulfone-based Film This is an amorphous sulfone-based film with high heat resistance and excellent electrical properties. - PSU (Polysulfone) - PES (Polyether sulfone) - PPSU (Polyphenylsulfone) * It also excels in rigidity, mechanical strength, dimensional stability, hydrolysis resistance, food hygiene, and resistance to hot water and steam. ○ SPS Film This is a film with low specific gravity and excellent electrical properties (especially low dielectric constant). It also excels in food hygiene and hydrolysis resistance.

Currently, the GTL series is limited to sales from existing inventory or new orders produced from raw materials. If you have any questions, please feel free to contact us. The prism sheet "GTL5000 and GTL6000 series" is an optical film for liquid crystal displays that features micron-sized prism patterns on its surface. It possesses optical characteristics that enhance light-gathering performance and alter the direction of incident light due to the lens effect of the prisms. It has been adopted in various applications, including liquid crystal TVs, computer monitors, car navigation systems, as well as sign lighting and automotive meters. The optical performance suitable for specific applications can be selected by combining the prism apex angle, back surface shape, and film thickness. Its polycarbonate single-layer structure makes it suitable for use in applications requiring heat resistance. 【Features】 ○ Single-layer structure primarily made of polycarbonate 　→ Excellent heat resistance and moisture resistance, with minimal warping under thermal conditions ○ Two different prism patterns with distinct characteristics in the lineup 　→ GTL6000 with high front brightness using 90° prisms and GTL5000 with superior viewing angle characteristics ○ Fine patterns are also molded on the back surface of the sheet 　→ Prevents Newton rings, enhances adhesion, and improves scratch resistance

The design sheet (decorative film with design features) is a functional film that is optimal for surface decoration of plastic molded products such as insert molding and vacuum forming, providing design characteristics through fine surface shapes. The D type, which has undergone "shape protection sheet processing (patent pending)" on its surface, is less likely to deform during insert molding due to heat and pressure, allowing it to maintain its design and tactile qualities. 【A lineup that can be selected according to patterns and applications】 ○ H type - A structure that imparts fine shapes to the surface UV-cured acrylic layer of a PET film substrate - Suitable for mobile devices and membrane switches that require surface hardness ○ D type - A single-layer film structure that imparts shapes to the surface during extrusion film molding - Allows for the selection of resins suitable for the application - Well-suited for vacuum forming and insert molding applications that require good thermal moldability and deep drawing capabilities.
