Introduction to the application of kraft paper bag in industrial packaging

kraft paper bags can be divided into single-layer kraft paper bags and multi-layer kraft paper bags in industrial packaging, which is suitable for the circulation and transportation of bulk goods.

industrial packaging kraft paper bag is a packaging container made of one or more layers of flat paper tubes with at least one end closed, which can be combined with other ductile materials (such as pp film) to achieve the various properties required by the filling and circulation of goods. The number of layers of the bag has 1 to 6 layers to choose, take single-layer kraft paper, can be directly made of single-layer kraft paper, can also be made of single-layer composite kraft paper obtained by other ductile materials and single-layer kraft paper, and so on.

The kraft paper for making bags can be made of several kinds of paper at the same time, such as: imported kraft paper or domestic kraft paper, stretchable paper bag paper or smooth paper bag paper, natural kraft paper or white kraft paper and other gram weight, wet strength and other reference options.

One or both sides of the kraft paper can be coated with a barrier material (such as: PP polypropylene film) or an insulating material (such as: silicide) according to the needs of the filling product.

Two or more layers of kraft paper bags can be combined with PE lining bags to make bags, pe film can be placed in the bag interval layer, can also be placed in the most inner layer, to play a waterproof, moisture-proof and leakproof role.
