Message from Top Management

DiaPlus Film Inc. was created in April 2014 through a merger between part of the industrial film business segment of the former Mitsubishi Plastics, Inc. and Ryoko Plastic Co., Ltd., a Mitsubishi Plastics subsidiary.
We currently manufacture and sell industrial films and sheets, focusing on polyvinyl chloride film, polyolefin film, and laminate products, which are custom made for customers.

We leverage our long years of experience and our track record in each of these business segments, meeting our customers' demands whenever possible and speedily providing high quality products.

In our new product development, as well, with the collaboration of our parent company, Mitsubishi Chemical Corporation, we actively develop products and carry out sales activities backed by our solid technical strengths.

We will continue to devote ourselves to developing, manufacturing, and selling products that please our stakeholders in each of our business segments. We look forward to your ongoing guidance and support.

SCROLL

As part of the Mitsubishi Chemical Group, we are contributing to the creation of a recycling-oriented society.

We are curbing waste production and promoting the recycling of raw materials.

  • We recycle the film waste generated in our manufacturing 　processes, reducing the amount of waste we produce.
  • We develop film made from biomass raw materials (e.g.: Mitsubishi Chemical Corporation Bio-PBS)
  • We develop film made using recycled raw materials (PE, PP).

We actively work to conserve resources.

  • We carry out activities aimed at reducing the amount of raw materials and utilities such as power, steam, and water, all of which are used in manufacturing.
