Toray Industries, Inc., Mitsui Chemicals, Inc., and Kumagai Co., Ltd., have jointly developed a revolutionary mono-material film packaging material and manufacturing process that are free of volatile organic compounds (VOCs). Carbon dioxide emissions are 80% lower than from conventional counterparts with this new material, which is also recyclable.

The lightness, transparency, and processing ease of these materials should make them popular choices for refillable pouch applications, including for foods, shampoos, and detergents. The market for these materials should keep growing more than 3% annually as the global population rises.

Regular film packaging material manufacturing uses petroleum solvents inks to print text, images, and other information on plastic films and in adhesives to laminate plastic films. These solvents release VOCs.

Toray, Mitsui Chemicals and Kumagai develop revolutionary mono-material film packaging material and technology.

The equipment required to heat, dry, and incinerate petroleum solvents in inks and adhesives consumes a lot of electricity. The lamination of plastic films with different materials to achieve various functions makes them hard to recycle, leading to their frequent incineration as waste.

VOC emissions from petroleum solvents in film packaging materials production have raised concerns about their impact on work environments. Another issue is the global warming impact of carbon dioxide emissions from their electricity consumption in production processes and from incineration during disposal.

These considerations prompted Toray, Mitsui Chemicals, and Kumagai to develop a mono-material film packaging material and manufacturing technology that is free of petroleum solvents for ink and adhesives and is recyclable.

Regular and mono-material packaging film comparisons.

Toray demonstrated printing for the new material’s manufacturing process by employing its Toray proprietary IMPRIMA offset printing plate. The plate uses electron beam-cured printing inks that consumer less electricity need no thermal drying. Mitsui Chemicals verified the lamination process with adhesives that do not incorporate petroleum solvents. The manufacturing process is thus VOC-free because it does not use petroleum solvents for inks or adhesives.

Incorporating Kumagai’s package manufacturing and processing technologies resulted in a mono-material film packaging material. This breakthrough makes the material far easier to recycle than regular counterparts.

Under this collaboration, Toray is leading the way with its printing technology. Mitsui Chemicals is providing total coordination for the new setup with its materials technology. Kumagai is leveraging its industry-leading package manufacturing technology. The three look to commercialize the new film packaging material for food and other daily necessities.
