[Topic 2] Environmental Business and R&D

Oji Group has been tackling environmental issues through its diverse business activities, and contributing to the creation of a sustainable society. We use LCA (Life Cycle Analysis) in product or system design to reduce the burden on the environment and CO2 emissions from the procurement of raw materials to manufacturing, sales, consumption, and disposal. We supply a variety of eco-friendly products and systems to society.

Development of Eco-friendly Materials and Products

To address the global issue of plastic in the ocean and contribute to the reduction of CO2 emissions, the Oji Group is developing eco-friendly materials and products, such as paper materials that can replace plastic packaging and biomass plastic materials made from renewable forest resources.

Cellulose-derived Biomass Plastics

The Oji Group has been considering manufacturing cellulose-derived biomass plastic. Unlike conventional plastic made from petroleum resources, cellulose is a wood fiber component and can significantly contribute to the reduction of CO2 emissions from fossil fuel into the atmosphere.
In addition, while most of the sugar used as a raw material for biomass plastic is produced from edible ingredients such as sugar cane and corn, wood is non-edible.
This means that cellulose-derived biomass plastic do not contribute to global food shortage problem. We also commenced development of biomass plastic films through the application of our film sheeting technology.

Environmentally friendly adhesive film “Eco Marine Tac™”

Oji Tac has developed Eco Marine Tac™, environmentally friendly adhesive film, in response to the issues of marine pollution and microplastics. Eco Marine Tac™ was launched in October 2019.
The surface base material of Eco Marine Tac™ is made of biomass materials that suppresses the emission of CO2 when incinerated, and is easily broken down (biodegradable, etc.) in the soil or ocean due to the use of biomass plastic. Eco Marine Tac™ is suitable for printing in the same way as PET or OPP labels, and are more water resistant than adhesive paper. A special and unique adhesive is used, that does not tend to inhibit the degradability of the biomass plastic used on the surface base material. Proprietary decomposition test were carried in sea water and soil. After six months in sea water, the weight of the adhesive film had decreased by 85%. Eco Marine Tac™ is registered under Plastics Smart, a campaign by the Ministry of the Environment to address marine plastic waste problems. The Functional Materials COMPANY will continue to engage in the development of environmentally-friendly products.

Eco-friendly Products Made from Pulp and Paper

SILBIO BARRIER, a Paper Alternative to Plastic

SILBIO BARRIER is a multibarrier paper manufactured using water-based coating technologies. The base paper adding a barrier coating layer prevents oxygen,water vapor, and other substances from passing through, curtailing deterioration of the content. As it has the functions equivalent to those of general barrier films, the multibarrier paper is expected to become an alternative material to plastic packaging materials.
In addition, we are currently accelerating the development of high-performance products with even higher barrier properties comparable to those of metalized films.

PaPiPress, Lids and Packages Made

Pulp lids, manufactured using a precise pulp-molding technology, are lids for paper cups with high fittability and applicable to both hot and iced beverages.
Other than lids, the pulpmolding technology is applied to different types of package as an alternative solution to plastic containers.

Pulp Composites

We are developing pulp composites. Created by mixing pulp into biodegradable plastic, the material has improved in properties such as strength and rigidity.
We are proceeding with its commercialization not only to contribute to reduction of the amount of plastic used but also to expand the applications of biodegradable plastic.

OK Rain Guard

This product is water-repellent paper for offset printing, which was developed based on woodfree paper. It is an environmentally friendly product, made from 100% natural pulp.
This paper is used for the labels of envelopes and perishable foods, exterior packaging paper, golf score cards, and other purposes. It has unlimited potential applications.

Paper envelopes with mesh paper as buffer

Use of these envelopes for home delivery services permits acceptance of goods via home delivery boxes, mailboxes, or similar items, thereby reducing redeliveries. In addition, these envelopes are made of paper, with even the buffer being made from paper, which reduces dependence on plastics.

Cup base paper, Acid-resistant cup base paper

The cup base paper features low impurities and excellent water resistance, molding characteristics and shape retention. It is used to make paper cups for beverages, ice cream, and instant soup. The acid-resistant cup base paper, which is a base paper for acidic foods, is used to make yogurt containers.
