DNP Develops Japan's First Insulated Paper Containers Using Biomass Plastic

Dai Nippon Printing Co., Ltd. (DNP) is pleased to announce the development of Japan's first insulated paper containers using plant-derived PET film and polyethylene resin. The containers that are suitable for use with soup and noodles will be launched on December 12.   

[New Product Development Background]

DNP has developed diverse examples of sustainable packaging with a low environmental burden. In 2012, the Company led the world in the mass production of PET film using polyethylene-telephthalate (PET) based on plant-derived raw materials in the form of blackjack molasses, being the residue following the refining of sugar from sugar cane. 2013 saw DNP develop transparent barrier film with heightened barrier features against oxygen and water vapor. DNP commercialized aluminum deposition film with superior barrier and light blocking features in July 2014, and in September of the same year, commenced the use of biomass plastic in paper containers with the development of paper containers for use with liquids by laminating the surface and inside of the containers with plant-derived polyethylene.

DNP developed insulated paper containers in 1998. The containers were formed with an air layer that produced the insulation effect between the internal cup and the external paper, and have been widely adopted as containers for miso soup, soups, ramen and dishes served on rice. The internal surface of the paper container is coated with PET film and nylon film joined with polyester resin in order to prevent odors arising from or moisture penetrating the contents of the insulated paper containers. The newly developed insulated paper container uses plant-derived PET film in place of PET film and nylon film, and plant-derived polyethylene in place of polyethylene resin. This new product will be used to target food containers as part of DNP's product lineup that combine the strengths of both existing insulated paper containers and plant-derived film.

[New Product Features]

  • Uses plant-derived material in all layers, achieiving biomass content of 95%+

Biomass content refers to the share of plant-derived biomass dry volume in the dry volume of all raw materials used. By using 20% biomass content PET film and 95% biomass content polyethylene resin, it has been possible to boost biomass content for the overall container to 95%+. This has been achieved by using plant-derived materials for all layers, including the outer package portion that originally used paper based on plant-derived raw materials. And as manufacturers can now display the biomass mark on their products this new development allows them to promote their companies to consumers as environmentally-friendly organizations.

  • Environmental responses

The newly developed insulated paper container successfully reduces petroleum usage volume by substituting plant-derived products for petro-derived materials, without sacrificing any of the existing functions. And in quantitatively evaluating the environmental burden reduction effect via a Life Cycle Assessment, it has been revealed that CO2 emissions throughout the entire life cycle of the product have been reduced by approximately 13% per product-unit life cycle compared to currently available products that use petro-derived polyethylene resin.

[Future Developments]

DNP will promote the switching to biomass film of packaging materials offered to the manufacturers of daily provisions. In addition to film products using plant-derived raw materials, the Company will also promote the switching to biomass film of paper containers aiming to contribute to the prevention of global warming. DNP aims for total sales of 15 billion yen by fiscal year 2017 from packaging using plant-derived film.
