2021202220232024202577796476595666718280(Fiscal years ended March 31) Moving Toward Solventless ProductsOrganic solvents, which are volatile organic compounds (VOCs), are used in many of the LINTEC Group’s products to dilute adhesive and release agents so they can be coated in thin, uniform layers. However, organic solvents can be harmful to the environment when they evaporate and are released into the atmosphere after coating. As lowering atmospheric emissions of VOCs is a key theme of the LINTEC Group’s long-term vision, LSV 2030, we are shifting toward the use of solventless products. In adhesive products, we are developing products for seals and labels using emulsion-based and hot-melt adhesives, which do not require organic solvents, and we are proactively developing and proposing solventless release paper. In 2021, we stepped up our efforts in the development of solventless products by installing new coating equipment for solventless release paper at the Kumagaya Plant. In line with our long-term vision, for release paper we are aiming for 100% of our products to be solventless by 2030. In tandem with these moves, we intend to further reduce atmospheric emissions by introducing equipment with high solvent treatment efficiency, such as low-concentration solvent gas concentrators. To reduce our environmental impact going forward, our research, production, and sales divisions will work together to move toward solventless solutions.The LINTEC Group is actively involved in developing and proposing environmentally friendly products as well as reducing the environmental impact of its manufacturing processes. By fulfilling our social responsibility as a manufacturing company while also viewing the growing environmental awareness among society and our customers as an opportunity, we aim to enhance our economic value as well.Note: For adhesive products for seals and labels, the figure is based on sales volume in Japan. For release paper, the figure is based on the total amount produced at the Kumagaya and Mishima plants (excluding certain specialty products).Percentage of Adhesive Products for Seals and Labels and Release Paper That Are Solventless%Coating equipment for solventless release paper (Kumagaya Plant) Adhesive Products for Seals and Labels 1007550250Sample application of solar-control window filmProposed for use as labels on plastic containers and other packaging Release Paper50Environment1. Environmentally Friendly Window FilmIn July 2025, LINTEC added a new solar-control type to its lineup of window films that uses 100% recycled polyethylene terephthalate (PET) resin for the surface base material. Compared with products made from nonrecycled PET resin, this film reduces CO₂ emissions by approximately 17.5%. When applied to the entire surface of a building’s windows, it reduces solar transmittance—particularly in the near-infrared range, which carries high thermal energy—by about 57%, helping to reduce heat inside the building. It also blocks over 99% of ultraviolet rays, which can cause skin damage and fading of building interiors. Additionally, the film helps prevent the scattering of glass fragments in the event of window breakage.2. Label Materials That Promote the Recycling of Plastic ContainersWe offer a label material that promotes the recycling of plastic containers. Labels made from this material can be removed easily in the cleaning process after container collection, allowing for efficient label removal and retrieval. Our material using polypropylene (PP)-based synthetic paper as a surface base material is intended for use on containers made from PET, which makes up the majority of plastic containers. By taking advantage of the specific gravity separation characteristics of PP, which floats in water, and PET, which sinks, we have made it possible to efficiently remove and collect labels during the container crushing and reclamation processes. We are proposing the use of our material, which complies with Japan’s Food Sanitation Act, for a wide range of applications, including labels for beverages and food products.
