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.

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.

【Manufacturing and Development of Biodegradable Films and Laminated Products】 We contribute to reducing environmental impact, such as the reduction of waste plastics, by using biodegradable plastics that completely decompose into carbon dioxide and water under specific conditions. Our company offers product development, prototyping, and contract manufacturing of various biodegradable resins, including marine biodegradable resins. Please consult us regarding replacements from existing plastics. 【Enhancement of Biodegradable Materials (Developed Products)】 Currently, the types of existing biodegradable resins are limited, and their functionality is restricted. Therefore, our company is advancing the development of high-functionality biodegradable products. - Odor Resistance: Adding odor resistance to fully biodegradable films made from biomass materials. Suitable for scenarios where odor is a concern, such as pet waste bags, used diaper bags, and emergency toilet bags during disasters. - Transparency: Improving the transparency and heat resistance of biodegradable resin films for packaging applications through modification. - Moisture Resistance: Enhancing moisture resistance by modifying biodegradable resins, which generally have low moisture resistance. This is expected to expand into packaging material applications.

Our representative product, PE (polyethylene) laminated paper, utilizes its sealing properties and moisture and water resistance, making it suitable for various food containers such as ice cream, cup soups, and both Japanese and Western sweets. Additionally, we laminate paper with aluminum foil or barrier films to create yogurt and snack containers that possess moisture resistance, gas barrier properties, and aroma retention. We also apply PET resin extrusion lamination to heat-resistant base paper, making it suitable for heat-resistant paper containers for microwave and oven-heated foods like gratin and lasagna, contributing to the preservation of food quality through various combinations. Furthermore, we have obtained FSC-CoC certification (Certification Code: FSC-C134306) and are engaged in laminated processing using plant-based biodegradable resins (such as PLA) and plant-based bio-PE, contributing to the realization of a sustainable society through the provision of products made from sustainable resources.

Our representative product, PE (polyethylene) laminated paper, is utilized in various beverage containers such as paper cups and paper packs for milk and juice, taking advantage of its sealing properties and moisture and water resistance. Additionally, it can be used for insulated cups for hot coffee by providing a foam layer on the outer surface of the cup to achieve insulation. By laminating paper with aluminum foil, which has excellent light-blocking properties, we can suppress oxidation deterioration of the contents and impart aroma retention for sake packs. We also offer various combinations, such as paper with holes and a barrier film substrate laminated on both sides with PE (polyethylene) for straw-equipped paper packs for sake, contributing to the maintenance of beverage quality tailored to our customers' applications. Furthermore, we have obtained FSC-CoC certification (Certification Code: FSC-C134306) and are working on laminated processing using plant-based biodegradable resins (such as PLA) and plant-based bio-PE, contributing to the realization of a sustainable society through manufacturing and providing products using sustainable resources.

It is a laminated product that combines the texture and feel characteristic of non-woven fabric with the waterproof properties of polyethylene, primarily used in the medical field for isolation gowns and surgical drapes. There are absorbent and waterproof types that minimize contamination spread to floors and other surfaces, as well as water-repellent types that prevent permeation contamination, thereby protecting surgical instruments. Being disposable, they contribute to infection prevention and hygiene management in hospitals. Additionally, there are urethane process papers used in the manufacturing process of adhesive bandages and release papers for sanitary products.

Our PP (polypropylene) laminated paper and PMP (polymethylpentene) laminated paper are used as process papers in the manufacturing of synthetic leather used in bags and wallets, low-resilience foam for cushions, seam tape, and more, supporting our customers' product development. Additionally, our PE pseudo-adhesive laminated paper allows for easy removal and disposal of personal information, such as addresses and names printed on delivery labels, contributing to the safety of your home. Furthermore, we offer various applications, including anti-mold sheets to protect clothing from mold, release paper for stickers, wrapping paper for copy paper, and processed paper used in fiber drums and paper tubes.

Insulation materials that allow for comfortable living at home regardless of the season and contribute to reducing electricity costs for heating and cooling. Our laminated products are also used for reinforcing surface materials and decorative papers for these insulation materials.

Our company also has an extrusion laminating machine installed in a clean room (Class 10,000), primarily processing film substrates with AC lamination, sand lamination, tandem lamination, and more, which are used for components and packaging materials for electronic and electrical equipment such as automobiles, semiconductors, and solar panels.

A combination of polyethylene cloth (fabric) and aluminum-coated PET film creates a robust, long-lasting agricultural (orchard) reflective sheet with high reflectivity. It can be easily laid out, and the perforated design also prevents the accumulation of rainwater. Additionally, there are processed products such as slug repellent tape that prevents the intrusion of slugs, which can damage petals, strawberries, and new shoots.

Silicone-coated paper, which has been sealed with polyethylene and other materials, is used for adhesive cleaners, release paper for labels, and craft tape (our company uses solvent-free silicone and employs a manufacturing process that does not generate VOCs, considering environmental impact). Additionally, various laminated products from Goyo Paper Co. are used in everyday items such as bath additives, powdered detergents, pest control product boxes found in drugstores, mold-resistant tape for wet areas, insect-catching sheets, cat litter boxes, adhesive heat packs, non-slip sheets for flooring, and window privacy films.
