Kraft cardboard (he is the kraft-liner) is a separate type of a cardboard which was developed for creation of a flat layer of a corrugated cardboard. This grade of a cardboard provides special durability to a product. Kraft cardboard is steady against influence from the outside, is good as transport packing or as a container for especially fragile goods.
As a rule, the kraft-cardboard is made of two layers. Its top layer has especially high durability. It is smooth, porous, it is steady against emergence of cracks, attritions, dents. This stability allows this material to keep esthetic properties, and smoothness a surface perfectly approaches to put the high-quality printing press. The back layer of a kraft-cardboard does it rigid, and also is suitable for gluing of a corrugated wavy inside layer when the corrugated cardboard is made
There are different options of a kraft-cardboard. Best of all are suitable for drawing the press (including full-color) and best of all those grades at which the top layer becomes covered with sulphatic cellulose look.
Fine consumer qualities (rigidity, durability, moisture resistance etc.) could expand scope of packing from a kraft-cardboard. It will be the fine decision if it is possible to overcome the prejudice existing at many producers and consumers against the esthetic value of brown color of the lower layer of this material. However gradually the relation to this type of a cardboard changes, thanks to successful design finds and to decisions. Gradually such packing becomes more and more fashionable both among designers, and among consumers.
Moreover, the container from kraft-cellulose costs to producers cheaper, and it does it more attractive, it allows to reduce the final price of a product. Kraft liner now widely apply when transporting loose construction materials, such as extinguished lime and cement, also he is used for packaging and transportation of various forages for animals and grain.
Do strong and beautiful packages which cost cheaper, than packages from paper of this material. As the packing material it is applied at production of boxes to various household goods, electroproduction and so on.
