Kraft paper has high tensile force, such as single light, double light, stripes, and no grain. Mainly used for packaging paper, envelopes, paper bags, etc. Kraft paper is divided into high, medium and low grades. The following Tengda plastic composite woven bags will introduce you in detail:

High-grade kraft paper is generally all wood pulp kraft paper

The texture is relatively tight, the thickness is relatively uniform, the toughness is good, and it has good pressure resistance, tensile resistance, tear resistance, puncture resistance, folding resistance and water resistance. The paper is smooth on both sides and has a more uniform ink absorption. There is less powder and lint. The above is the comprehensive characteristics of various types of all-wood kraft paper.

High-grade kraft paper is widely used in high-end handbags, hand-rolled bags, food packaging bags, cartons, cardboard, and packaging boxes. In addition to Russian

Sri Lankan kraft paper has its unique high temperature performance, so it is still very good for electronics factory PCB separator paper.

Mid-range kraft paper is usually mixed Kraft paper

In addition to being unsuitable for food packaging, it is a good choice for hardware packaging, electronic products, color boxes, glass packaging, and slitting. Due to the increasing scarcity of raw material and the continuous increase in cost, there are already too many factories that produce kraft pulp, and they have already moved to the market for mixed or recycled paddle paper.

Low-grade kraft paper is generally recycled kraft paper

Recycled kraft paper is a paper that has been smashed and recycled by manufacturers after recycling waste paper materials and processed through a variety of processes. Judging from the appearance, one aspect of recycled kraft paper is relatively rough (smooth side is to meet the printing needs of some customers), combined with its low price advantage, the application of recycled paper is in a good trend. Here, in order to effectively save your procurement costs, Haoba Tenda woven bags recommend that you try to choose the right paper, just buy right, not expensive.
