Abstract

The invention discloses a cake paper base paper, wherein the slurry of the cake paper base paper comprises 15-30% by mass percentage of virgin coniferous wood pulp and 70-85% of virgin hardwood pulp, and the coniferous wood pulp The beating degree of the pulp is 30-40°SR, and the beating degree of the hardwood pulp is 25-35°SR. The prepared base paper for cake paper has a basis weight of 30-60g / m2, a dynamic friction force of ≤4.0N, and a smoothness of 20-120s. The cake base paper prepared by the production process of the invention has no peculiar smell and no static electricity, and the surface of the cake base paper is flat and smooth, and the handle is smooth, which overcomes the problem of poor separation effect between the cake base papers.

Description

technical field [0001] The invention belongs to the technical field of paper processing, and in particular relates to a cake base paper and a production process thereof. Background technique [0002] There are many kinds of cake paper trays. One kind is relatively thin made of oil paper. This kind of paper has been specially treated so that it is not easy to be soaked by water and not easy to stick to the cake. Another type of paper that is thicker cannot be recycled paper, and fluorescent whitening agents cannot be added, which will not affect health. The cake paper tray is oil-proof, high temperature resistant, strong in stiffness, and does not fade. When in use, put the paper cup into the baking tray fabric and put it in the paper cup, and then it can be baked in the oven. The baked cake is both beautiful and hygienic. [0003] The cake paper tray can effectively prevent people from being polluted by the grease on the cake when they take the cake. Therefore, the cake wi...
