If you need to print LOGO on the outside of your package, you can use all-wood pulp. kraft wrapping paper, and the actual effect of printing out all wood pulp kraft wrapping paper is very good.

Kraft paper

Why is kraft paper widely used?

In fact, kraft paper is the hard paper used to hold cement in the past. Its material is firm, its surface is brown and its compressive strength is high. It is found that the wood fibers commonly used in making kraft paper are relatively long, and when steaming wood, chemicals such as sodium hydroxide and vulcanized rubber alkali can be used to solve the problem, so that the chemical reaction between them is more relaxed, and the original compressive strength of wood chemical fibers is limited. The damage suffered is relatively small, so the paper made of this type of paper pulp is firmly attached between chemical fibers and chemical fibers, and is very strong.

And kraft paper is divided into three types: single-sided, double-sided and pattern; according to its thickness, it is divided into kraft paper, kraft paper card, and kraft cardboard.
