明光堂 List of Products and Services

The SDGs (Sustainable Development Goals) recommend the use of materials that consider the natural environment, and there is a demand for product development using materials with low environmental impact (sustainable materials). Among sustainable materials, there are various types, including those that can be recycled, those that naturally decompose in soil, those that are not derived from petroleum, and those that can reduce CO2 emissions. Our company has been proactive in product development and has developed several sustainable products. 【Examples of product development using sustainable materials】 ■ Efforts to transition from plastic to paper We have been working on the development of apparel materials using paper. We have successfully developed paper products that have durability comparable to plastic and can naturally decompose in the environment. ■ Reuse of palm oil waste The refining process of palm oil generates a large amount of waste, which has been a cause of environmental pollution and has been a concern for many years. Our company is advancing product development using resins made from this industrial waste. *For more details, please refer to the PDF document or feel free to contact us.

"Thompson (Bik) die-cutting" is a processing method that uses a wooden die called a Thompson die to punch materials through press processing. The Thompson die has blades embedded in it, which are usually embedded in rubber, but during the press processing, the blades emerge from the rubber, allowing the material to be punched out. At our Osaka factory, we utilize Thompson die-cutting, press die-cutting, punch die-cutting, and sheet material bonding to manufacture various products. If you are considering the development of sheet material products, please feel free to consult us. [Features] - Can accommodate thin and soft materials - Strengths include low initial costs and quick die lead times - Suitable for a wide variety of small lots - Equipped with facilities that can continuously punch from roll materials *For more details, please refer to the PDF materials or feel free to contact us.
