Two-side offset paper suitable for paper bag and preparation method of two-side offset paper

Abstract

The invention discloses a two-side offset paper suitable for paper bags and a preparation method thereof, the two-side offset paper comprises 25%-50% of masson pine, 50%-75% of broad-leaved wood, 55.3 g / m < 2 >-64.8 g / m < 2 > of fortified rosin size, 58.4 g / m < 2 >-66.9 g / m < 2 > of starch, 59.8 g / m < 2 >-63.4 g / m < 2 > of water glass, and AKD (Alkyl Ketene Dimer) glue. The proportion of the AKD glue is 56.1 g / m < 2 > to 63.3 g / m < 2 >. According to the two-side offset paper suitable for the paper bag and the preparation method of the two-side offset paper, starch particles are dispersed in water to form suspension potted base paper through starch added through a spraying method, and the starch particles are wrapped by fibers, so that the stiffness, tightness, tearability and interlayer bonding strength of the paper industry are improved, and the water permeability of the paper industry is greatly reduced; through the starch and the AKD glue, the galling speed of the surface of finished paper can be increased, and the prepared two-side offset paper is small in flexibility, uniform in ink absorption, good in smoothness, compact in texture, non-transparent and high in water resistance.

Description

technical field [0001] The invention relates to the field of preparation of offset paper, in particular to an offset paper suitable for paper bags and a preparation method thereof. Background technique [0002] Offset paper refers to printing paper, also called offset paper. It is one of the typical representative paper types for cultural and printing paper. In business, it is abbreviated to double-sided offset paper. Double-adhesive paper refers to the paper in which glue is applied to both sides of the paper to improve its surface properties during the papermaking process. It has small stretchability, uniform ink absorption, tight opaque texture, and strong water resistance. After the adhesive tape is applied to the paper bag, the tensile strength will not be high, which will cause it to be easily damaged, and there will be a lot of burrs on the surface, which will affect the touch. When printing, it does not have good printing adaptability, resulting in There will be pow...
