The invention belongs to the field of ultraviolet curing ink, and relates to UV gravure white ink for a food packaging BOPP film, and a preparation method thereof. The UV gravure white ink is preparedfrom the following raw materials by weight: 8 to 15 parts of polyether polyol aliphatic polyurethane acrylate, 8 to 15 parts of polyester acrylate, 30 to 40 parts of dipropylene glycol diacrylate, 2to 6 parts of pentaerythritol triacrylate, 1 to 3 parts of 819, 1 to 3 parts of 1173, 0.3 to 0.8 part of Tego-Foamex N, 0.8 to 1.5 parts of DC-57, 0.3 to 0.8 part of Tego-655, 3-8 parts of talcum powder, 3-8 parts of light calcium carbonate, and 15-30 parts of titanium dioxide. The ink is applied to food packaging BOPP films, the printing speed can reach 200 m/min or above while the low cost is guaranteed, and the ink is good in adhesive force and resistant to abrasion and is environment-friendly UV photocuring ink.
