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.

"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.

At Goyou Paper Co., we have developed a technology to release natural and artificial fragrances into the air. This technology can be applied to various products. By incorporating volatile agents that provide insect-repellent effects, antibacterial and antifungal properties, and the ability to deter certain household pests, it is also possible to achieve a fragrance plus additional benefits. 【Features of Fragrance Film】 - By placing a scented film, you can easily create a living space that suits your preferences. - Fragrances have various effects, including relaxation, appetite control, and enhanced concentration. - Additionally, one of the side effects of fragrances is pest-repellent properties. - It is also possible to pelletize highly volatile agents similar to fragrances for film formation. Please utilize fragrance films and laminated products for the development of new products and more. *For more details, please download the PDF or contact us directly.

- GK Tect is a general term for special film products that contain agents that slugs and unpleasant pests dislike. - The newly developed GK-II film not only protects fruit trees and outdoor electronic devices from slugs but also prevents the intrusion of unpleasant pests and is effective in inhibiting the growth of bacteria and mold. - GK-M film prevents the intrusion of dust mites lurking in homes and blood-sucking mites that target humans and livestock. There is also a lineup specialized for various other pests. - GK-B film, which is specialized in antibacterial and mold prevention, can be used for food-related applications.

- A sticky tape that incorporates a highly safe antifungal agent registered with the FDA into the adhesive. By controlling the evaporation of the antifungal component, it achieves a long-lasting antifungal performance in the space. - Adhesive characteristics can be customized according to the application, such as reusable peelable adhesive types or strong adhesive types. - It helps suppress mold growth in storage bags for leisure goods, cloakrooms, shoe boxes, and areas prone to mold growth such as kitchens and bathrooms, contributing to a comfortable living environment.

- 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.
