Materials introduction

Kraft paper is a tough, water resistant wrapping paper. It's brownish yellow and has a wide range of uses. It's used for making paper bags, envelopes, workbooks, albums, files and sandpaper. The quantitative range is 80 g / ㎡ to 120 g / ㎡. There are differences between web and flat paper, single side light, double side light and stripe. The main quality requirements are flexible, strong, high breaking resistance, can withstand greater tension and pressure does not rupture. Kraft paper has a high tensile force, with single light, double light, stripes, no grain, etc.. Mainly used in packaging paper, envelopes, paper bags and printing machine drum lining, etc..

Speciallity
A few points to be paid attention to in the printing of kraft paper: Pay attention to the color of printing In order to get better color copy in the [3] printing of kraft paper, it is more difficult to print than SBS paper. In particular, the exact reproduction of color on the ordinary cowhide board requires more careful printing than on bleached cowhide paperboard. Because the ordinary kraft paper itself is dark brown,
Brief Introduction
Kraft bubble mailers Kraft bubble mailers or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process. Sack Kraft bubble mailers, or just sack paper, is a porous Kraft bubble mailers with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability. Pulp produced by the kraft process is stronger than that made by other pulping processes; acidic sulfite processes degrade cellulose more, leading to weaker fibers, and mechanical pulping processes leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. Low lignin is important to the resulting strength of the paper, as the hydrophobic nature of lignin interferes with the formation of the hydrogen bonds between cellulose (and hemicellulose) in the fibers.
