AI Technical Summary

Technical Problem

Existing non-fluorine resin-based oil-resistant agents for paper struggle to achieve both high oil resistance and high air permeability, leading to decreased flavor and storage stability of packaged foods, and they often require large amounts of blocking agents, which further compromise air permeability.

Method used

An aqueous oil-resistant agent composition comprising cellulose-based resin, addition-curable silicone emulsion, and platinum group metal-based catalyst, with specific ratios and structures of alkenyl group-containing organopolysiloxane and organohydrogenpolysiloxane, is used to treat paper substrates, enhancing oil resistance and air permeability.

Benefits of technology

The composition results in oil-resistant paper with high oil resistance, water resistance, and improved air permeability, maintaining food flavor and stability, while being environmentally safe and recyclable.
