MCC develops technology to create PFAS-free oil-resistant paper packaging
Last update on Jan 6, 2026
Mitsubishi Chemical Corporation announces the development of a technology that coats paper substrates with a solution of the SoarnoL™ resin used in food packaging materials to impart gas barrier properties and oil resistance.
Forms stable barrier layer by coating paper substrates with EVOH solution
SoarnoL™ is an ethylene vinyl alcohol copolymer (EVOH) developed using proprietary MCC technology that offers high gas barrier performance, oil resistance, and transparency. Used as films, sheets and other food packaging materials by being combined with other resins and thermoformed, SoarnoL™ helps preserve food flavor and quality longer, thereby contributing to reduce food loss.
The technology developed by MCC enables the formation of a stable barrier layer by simultaneously coating paper substrates with SoarnoL™ solution and an anchor coating agent. This technology imparts SoarnoL™’s excellent gas barrier properties and oil resistance to the paper.

Provides better performance than PFAS-based packaging
While PFAS are commonly used to enhance the oil resistance of paper packaging materials, this new technology achieves oil resistance surpassing that of PFAS-based packaging materials even under high temperatures and foldling. SoarnoL™ meets the high hygiene standards required for direct food contact, making it suitable for food packaging applications such as fried chicken and hamburgers. With PFAS regulations tightening globally, demand for PFAS-free oil-resistant paper is expected to grow, so MCC will be seeking assessments from customers and others as it aims for adoption sometime in fiscal year 2026.
MCC plans to exhibit this technology at the New Functional Materials EXPO 2026 to be held at Tokyo Big Sight from January 28 to 30, 2026. MCC’s “KAITEKI Vision 35” management vision identifies “food quality preservation” as a business focus area. By providing environmentally conscious materials that support food quality preservation, MCC will be contributing to societal sustainability.
