Flexible packaging materials are film materials used for packages for food and other products. Currently gravure (Glossary 1)
and flexographic (Glossary 2)
processes predominate in printing these materials. A drawback is that these setups consume a lot of printing ink incorporating organic solvents and thereby, consume energy and emit CO2
when thermally drying these solvents and when treating waste gas generated. This situation has driven the adoption of offset printing (Glossary 3)
that is free of organic solvents and employs printing inks that is cured with electron beam or ultraviolet processes that consume less energy.
Toray produced estimates based on Product Category Rule PA-BC-02, the Japan Federation of Printing Industries’ calculation standard for plastic containers and packaging. The estimate confirmed that CO2
emissions from employing IMPRIMA TM FR with flexible packaging printing are up to more than 80% below those from gravure printing and more than 60% lower than those from flexographic printing. Furthermore, applying electron beam curing printing ink enables Toray’s process to comply with restricted substances list requirements, which are becoming increasingly stringent for food packaging.
The Toray Group Sustainability Vision and Toray Vision 2030 state the company’s commitment to helping resolve environmental, resources, and energy issues through business. Toray will continue to develop advanced materials and processes in line with its commitment to innovating ideas, technologies, and products that deliver new value.
