How can you tell if kraft paper is imported or domestic?

American kraft paperAmerican kraft paper is imported American kraft paper, which is also double-sided, that is, both sides are the same.

The general kraft paper has domestic imported domestic domestic generally single-sided...

Hot-melt adhesive-free kraft paper tape is mainly made of silicone oil coated on the surface (silicone oil-based paper), and the adhesive surface is coated with hot-melt adhesive or rubber and other self-adhesive products.

Because this kind of kraft paper is deformed, the surface is waterproof, and it will not be bonded with the adhesive surface, so it is easier to use.

But it is also the case that kraft paper materials are easy to be oxidized and deteriorateIt should not be stored for a long time.

The hot-melt adhesive type of water-free kraft paper tape cannot withstand excessive temperatures, and after a long time of bonding, it is easy to warp the corners and cannot ensure that the bonding is used for a long time.

The rubber-type water-free kraft paper tape can withstand high temperatures, but the ratio is higher than that of the hot-melt adhesive water-free kraft paper tape.

Wet water kraft paper tape is mainly made of kraft paper material bottom coated with wet water glue, wet water glue belongs to the plant starch glue, does not have its own viscosity, and needs to be watered (coated with water) before it will produce stickiness.

The wet kraft paper tape is stronger than the water-free kraft paper tape in terms of viscosity, and the surface kraft paper material has not been used in any process, so it is significantly weaker than the water-free kraft paper tape in terms of tensile force.

However, due to the long-term improvement process of market demand, the tensile strength of ordinary wet water kraft paper has also been strengthened after composite clamping (reinforced wet water kraft paper tape).

The advantage of wet water adhesive compared with hot melt adhesive is that the cost of wet water adhesive is not high, and the adhesion is stronger than that of hot melt adhesive, and there will be no corner warping, or it is not resistant to high temperatures.

However, different wet adhesives are very glued to materials with smooth surfaces (non-absorbent), so the choice of kraft paper tape still depends on your own needs.

The requirements for printing are also different.

Because water-free kraft paper needs to be coated with silicon, it needs to be printed before kraft paper is processed, and its cost is relatively high, and the minimum order production volume is significantly higher than that of wet kraft paper.

Wet kraft paper tape printing does not need to complete the printing process before productionIn terms of production process, it is simpler than water-free kraft paper, so the wet kraft paper tape printing is less than half of the water-free kraft paper tape in terms of cost. And in terms of MOQ, wet water kraft paper tape also has a stronger advantage.

That's right, thank you.

Yes. Chose as the answer: Thank you. Yes.

There are some obvious features that distinguish the two kraft paper products, and there are some of the following distinguishing points.

First, the ratio of long and short fibers.

At present, most of the domestic kraft paper manufacturers do not have their own pulp mills, most of the wood pulp to rely on imports, in order to meet the production demand, import a large number of commercial pulp, due to the world's best wood pulp, it is difficult to control the quality of wood pulp, so the short fiber content of domestic kraft paper is generally higher, which can be seen from the tear of kraft paper, and most of the imported kraft paper is close to the origin of wood pulp, the wood pulp used is pure, often high long fiber content, and the strength of the kraft paper produced is relatively high.

Second, the original label.

This is the easiest to identify customers who need roll base paper, domestic kraft paper labels and imported kraft paper labels have seen it, this is also the easiest way, of course, this method is only suitable for customers who buy roll base paper, if you want flat products, it is not applicable.

3. Tensile strength and tear to judge.

When the domestic kraft paper is torn, it is obvious that it is more brittle, and when the imported kraft paper is torn, it is obvious that there is a strong tensile force to prevent it, which is said to be repeated with the first article, mainly because the long fiber content of imported kraft paper is relatively high, so the pulling strength will be better.

The wood fibers used in the production of kraft paper cavity width are relatively long, and when cooking wood, they are treated with burning bright round alkali and sulfide alkali chemicals, so that the chemical effect they play is relatively mild, and the damage to the original strength of wood fibers is relatively small, so the paper made of this pulp is closely interdependent between fibers and fibers, so kraft paper is very strong.

When ordinary paper is made, the wood fiber usually used is relatively short, and the production does not consider whether the wood pulp is used, and the paper produced is very different from kraft paper.

Kraft paper is stronger than ordinary paper, mainly depending on the material used to make the round, but the production process is similar to that of ordinary paper; The kraft paper cover bridge has good toughness and strong tensile force, so it is also very different from Putangan stuffy lead paper in terms of use.

Which domestic kraft paper is better? In the case of domestic kraft paper, Shuntonglai kraft paper is a better Shuntonglai kraft of this brand. It is relatively well-known in China.

Domestic kraft paper manufacturers can find Lijin technology, from mobile phone digital packaging to hardware packaging, from clothing packaging to shoe box packaging, from food packaging to industrial packaging, kraft paper is widely used. You can find the right kraft paper products according to your needs.

The quality of kraft paper in Changhuan Paper is relatively good, and there are also copy paper, mark paper, corrugated paper, flower paper and other packaging paper.

When I was young, many foods were packaged in kraft paper, such as cakes, and moon cakes were packed in kraft paper.

Which domestic kraft paper is better? You know?

I'll look it up.
