Choice of bag material
2022-08-28 13:39
Cardboard has good stiffness but poor toughness. If making paper bags, it needs to be covered with a surface film. Kraft paper has good toughness and high strength but has a rough surface, while coated paper has a certain degree of toughness. The printed colors are rich, but the stiffness is not as good as that of cardboard. If you want good durability, generally choose kraft paper, if you need rich and gorgeous pattern effects, generally choose coated paper, if you have requirements on color and stiffness, it is recommended to choose cardboard.
