Method for making paper special for E-commerce

Abstract

The invention relates to a method for making paper special for E-commerce. The method includes the steps of beating, pulp mixing, accessory adding, wet paper sheet making, predrying, surface sizing, postdrying, calender finishing and the like conducted on softwood pulp and hardwood pulp; the fixed quantity of the made paper special for E-commerce is 60 g / m<2>, moisture is 5-6%, raw white or ISO whiteness is 100%, tensile strength is larger than or equal to 4.0 KN / m, internal bond strength is larger than or equal to 400 J / m<2>, the ash content is smaller than or equal to 15%, the average value of smoothness is larger than or equal to 100 S, water absorption stability is 20-25 g / m<2>, a long broken roll of paper is larger than 7000 m in the longitudinal direction, transverse folding strength is larger than or equal to 15 times, and the transverse ratio of expansion and contraction is smaller than or equal to 3.0%; high yield pulp is not contained; the paper is good in evenness, fine in appearance, good in flatness and good in touch handfeel.

Description

technical field [0001] The invention relates to a method for manufacturing special paper for e-commerce, and belongs to the technical field of papermaking. Background technique [0002] With the rapid development of e-commerce companies and third-party logistics distribution companies serving e-commerce, it also drives the rapid development of the label paper industry. At present, the fastest growth rate in the label paper industry is the three-layer express label and logistics label, increasing at a rate of 60%. The so-called three-layer express label and logistics label, also known as three-layer self-adhesive face sheet, e-commerce face sheet, is a new type of self-adhesive face sheet, which is composed of three layers of top paper, middle paper and bottom paper. Material (including e-commerce special paper surface material, thermal paper surface material, coated paper surface material, carbonless paper surface material, etc.) Xin bottom paper (or other release paper) i...

Problems solved by technology

[0003] The current status of logistics label face paper used in China is mainly medium and high-grade thermal paper, and a small amount of carbon-free base paper and coated paper are used; although these products can basically meet the requirements of use, there are still the following problems: ① Existing logistics labels The flatness of the surface paper is average, and the consumption of coating paint is high during the coating process (primer coating, top coating, top coating and water pumping) and the cost is high

②The quality of medium and high-grade heat-sensitive base paper is good, but the price is high and the cost is high; other surface papers (carbon-free base paper and coated paper) have low tensile strength and interlayer bonding force, and the logistics label surface paper will be removed from the label after printing. The surface paper is sometimes easy to tear when the package is separated; ③The ration of medium and high-grade heat-sensitive base paper is too large, the price is high, and the production cost of a single label is relatively high; ④Compared with the high quality requirements of the logistics label surface paper, carbon-free base paper and coated paper The quality of surface paper is lacking, the cost of coating and processing is high, and there are many problems in the process of use. It is gradually being eliminated by the market.
