Multiple corrugated paper frames are fixed together by connecting pins 3 through pin holes 112.

[0018] As can be seen from this embodiment, an oil-resistant corrugated paper includes a board frame 11, a corrugated frame 12, and an oil-separating layer 2; The board frame 11 is made of cardboard and multiple pieces are evenly spaced. Corrugated frame 12 is placed between adjacent board frames 11, thus forming a corrugated paper skeleton board 1 in conjunction with the board frame 11. The oil-proof layer 2 covers the outside of the formed corrugated paper skeleton board 1 and isolates the grease. Furthermore, pin holes 112 are formed at both ends of the board frame 11. After multiple corrugated paper skeleton boards 1 are fitted together, the pin holes 112 are concentric and fixed by connecting pins 3. The board frame 11 and the corrugated frame 12 work together to form the corrugated paper skeleton board 1, which plays a role in enhancing the structural strength. The oil-proof layer 2 covers the outside of the corrugated paper skeleton board 1 to form a complete corrugated paper. The design of pin hole 112 and pin post 3 meets the requirements of flexible assembly. The overall design takes into account structural reliability, grease resistance and ease of use, and is suitable for packaging scenarios that require grease barrier, such as food (such as fried food and meat).
