五洋紙工 Product Lineup

Goyou Paper Industry is a technical partner that broadly addresses development challenges related to film and laminate products, from mass production to improvements of existing products. We provide consistent support for challenges such as "I want to consult about a development theme that may not be feasible," "I want to evaluate new materials by turning them into films," "I want to prototype on a small scale before mass production," and "I want to review the quality, cost, and supply system of existing products," covering material examination, processing condition review, prototyping, evaluation, and mass production launch. Based on our extrusion lamination processing technology and film manufacturing technology, we offer proposals tailored to our customers' objectives, including fine shape formation on film surfaces, blending of functional materials, processing of high-performance resins, and substitution with environmentally friendly materials. Leveraging the technical expertise and quality assurance systems cultivated across a wide range of fields such as food and beverage packaging, medical, electronic components, automotive, building materials, and life sciences, we support everything from new development to enhancing the value of existing products.

Goyou Paper Co., Ltd. has been engaged in the manufacturing and sales of waterproof and moisture-proof processed paper, which is essential for distribution systems, since its establishment in 1950. While capturing the needs of a changing era, we have consistently strived for advanced technological development and the evolution of original products under the spirit of "one and only." We will continue to conduct further research and refinement aimed at establishing advanced processing technologies required for the next generation and pioneering business development in a market with infinite expansion to carve out the future. 【Business Activities】 ○ Manufacturing and processing sales of polyethylene and other synthetic resin laminated materials based on paper, non-woven fabric, film, etc., as well as various packaging materials and laminated materials. ○ Manufacturing and processing sales of high-function film products such as prism sheets and design sheets. ○ Contract processing of high-function film products achieved through a combination of various technologies such as surface microstructures, functional agent blending, and multilayering. *For more details, please refer to the PDF materials or feel free to contact us.

The "Custom Made System" supports film development and contract processing tailored to customer specifications, from planning and development to mass production. We have newly installed a multilayer extruder on our small-scale test machine line, which has an effective width of approximately 200mm, capable of handling 2 to 3 layers up to 5 layers. Until now, the development of multilayer films and laminates could only be verified on actual mass production lines during the initial consideration phase, but we expect that the possibilities for new development will greatly expand in the future. *The conventional single-layer extrusion test equipment can still be used as before. Please make use of our "Custom Made System" for the development of high-functionality and high-value-added new films.

Do you have any experience with wanting to form fine shapes on the film surface, wanting to create a special compound resin into a film, having resin pellets but no film grade available, being turned down due to small lot sizes, being able to prototype but not mass-produce, being unable to film due to soft materials or tacky materials, or being unable to laminate in a clean room? If you have any issues with T-die extrusion, please consult us first. From prototyping with a small test machine to production with mass production machines, we will do our utmost to meet your needs! <General Environment> - Small extrusion test equipment with an effective width of approximately 210mm (single-layer to multi-layer, up to 3 types and 5 layers) - Mass production machines for extrusion lamination processing with effective widths from 620mm to a maximum of 2,150mm (multiple units) *Additional equipment: Co-extrusion, sand feed device, double-sided tandem, corona treatment, after corona, frame treatment, detectors, etc. <Clean Room> - Medium mass production machine with an effective width of approximately 650mm (single-layer) - Large mass production machine with an effective width of approximately 1,300mm (multi-layer) - Mass production machines for extrusion lamination processing with effective widths from 800mm to 1,400mm (AC treatment, sand feed device, single-sided tandem)

○ Surface Micro-structured Film Precisely forming micro to nano-sized fine shapes using a Roll to Roll method to enhance the functionality of the film. We have a track record in optical films, microfluidic chips, decorative films, and more. ○ Functional Agent Blended Film Example) Wavelength Cut Film: Please consult us regarding base materials and desired cut wavelength range. ○ Multilayer Film - Property adjustment with different materials: rigidity (soft to hard), increased strength, adhesion enhancement, etc. - Material cost reduction: Thin film multilayer structure using expensive functional materials. *Further enhancement of functionality through surface micro-structuring and high-functional agent blending.

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.

"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!
