White release base paper and manufacturing method thereof

The invention relates to the technical field of papermaking, and provides white release base paper and a manufacturing method thereof, and the method comprises the following steps: proportioning pulp according to a ratio of 5-15%: 85-95% by using bleached sulfate needlebush chemical pulp and bleached sulfate broadleaf wood chemical pulp as fiber raw materials, the raw paper product is prepared by sequentially carrying out seasoning, impurity removal, sizing, net part dehydration forming, squeezing, pre-drying, surface sizing, post-drying and press polishing on the raw paper product; the bleached sulfate broadleaf wood chemical pulp adopts compound enzyme to assist in pulping, and the pulping degree is controlled to be 42-46SR; non-ionic hydroxypropyl guar gum which is 1.5 kg/t or above of paper is adopted in the sizing pulp. The white release base paper product prepared by the invention has the advantages of excellent paper surface fineness, favorable layering force, favorable uniformity and excellent film sp
