Abstract
The invention relates to extensible paper for a paper bag and a production method thereof. The method comprises the following steps of: adopting the components in proportion by weight, i.e. 70-100 of masson pine kraft unbleached pulp and 0-30 of eucalyptus kraft unbleached pulp, proportioning the pulp, beating in line with the pulping concentration ranging from 23 percent to 28 percent and the beating degree ranging from 15 to 24 o SR, and carrying out the following procedures after beating, i.e. desanding, proportioning, fine sieving through a pressurized screen, forming through netting, squeezing, pre-drying, extensible compressing, post drying, coiling, recoiling and packing, to obtaine the extensible paper for the paper bag. The longitudinal tensile index of the paper is from 54 to 62 Nm/g, the longitudinal elongation percentage is from 6.0 percent to 8.1 percent, the longitudinal tensile energy absorption index is from 2.2 to 3.3 J/g, the longitudinal tearing index is from 15 to 22 mN m 2/g, the bursting index is from 4.3 to 5.3 kPa m2/g, and the degree of aeration is from 3.5 to 15 micron/Pa s.
Description
technical field [0001] The present invention relates to a kind of paper and its production method, in particular to a kind of stretch paper bag paper and its production method. Background technique [0002] Extensible sack paper is an updated product of ordinary paper sack paper. The requirements of tensile strength, elongation, tensile energy absorption index, tear index, burst resistance and air permeability of extensible paper sack paper are better than ordinary paper sack paper. Therefore, the pulp for the production of extensible paper bag paper generally uses all-coniferous wood long-fiber kraft natural color pulp to meet the product quality requirements. However, domestic coniferous wood fiber raw materials are in short supply, and there are many small and medium-diameter materials, and the fiber quality is low, which limits the elongation. The output and quality of stretchable sack paper are improved. On the premise that the product quality meets the quality requirem...
