The invention discloses an ultrahigh strength glassine base paper and a production technology thereof. The production technology comprises the following steps: selecting Shanxi white bark pine, Linyi 3-5 year fast-growing triploid poplar, compounded chopped polyester fiber and alkali-free glass fiber as production raw materials; preparing the white bark pine, poplar, chopped polyester fiber and glass fiber into pulp; and preparing the pulp, making paper and lastly forming the paper. According to the production technology for the ultrahigh strength glassine base paper disclosed by the invention, the domestic white bark pine and poplar which are conveniently pulped and high in pulp yield and the chopped polyester fiber and glass fiber which can greatly promote the toughness, strength and rigidity of the end product of the paper are selected as the raw materials and the processes, such as, optimizing the pulp, preparing the pulp, making paper and post-processing, are performed, so that the physical properties of the glassine base paper are obviously promoted, the defect of easiness in breaking and cracking of the glassine in the use process of the product acquired by adopting the traditional raw materials and method can be overcome and the ultrahigh strength glassine base paper has excellent end-product paper properties and market value.
