Kraft paper introduction
Features:
Kraft paper is tough and water-resistant packaging paper, brownish yellow, very versatile, commonly used in the production of paper bags, envelopes, operating books, record sets, files and sandpaper. The quantitative range is from 80 g/m2 to 120 g/m2, with the difference between single-sided light, double-sided light, and stripes in web and flat paper. The main quality requirements are flexible and strong, high burst resistance, can withstand greater tension and pressure does not break. 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.
specification:
Flat paper specifications: different according to the machine, but different cut. Like
A typical reel slitter can be cut to a minimum of 460mm and can be cut to a maximum of 1460mm. Then you can cut any size you want by cutting the machine. Printing commonly used specifications are: positive 787*1092mm, generous 889*1194mm.
classification:
Kraft paper usually retains its tan color and is suitable for bags and wrapping paper. Depending on the nature and use, kraft paper has a variety of different uses. Kraft paper is a general name for a kind of paper, and there is no certain standard. Generally, it is classified according to its nature and purpose.
In accordance with the different colors can be divided into: primary color kraft paper, red kraft paper, white kraft paper, plain kraft paper, single light kraft paper, kraft paper and so on.
According to the use of different can be divided into: packaging kraft paper, waterproof kraft paper, moisture-proof kraft paper, rust-proof kraft paper, kraft paper-making, process kraft paper, insulation Kraft board, leather stickers and so on.
According to the different materials can be divided into: recycled kraft paper, kraft core paper, raw leather, rough kraft paper, Kraft wax paper, wood pulp kraft paper, composite kraft paper.
Kraft paper color reasons:
Different sources of raw materials for kraft paper, different production batches, different production seasons, different production machine stands, and many other reasons will affect the color of the kraft paper roll base paper. This color is not the same as it is difficult to avoid and cannot be controlled. , generally the same batch of kraft paper can guarantee 98% consistent color.
application:
Kraft paper [1] is used in various industries such as chemical engineering and machinery, and is widely used in the food packaging industry.
Kraft paper use: Kraft paper is widely used in various packaging supplies, paper bags, handbags kraft paper, color box, gift box kraft paper, printing kraft paper
Printing kraft paper, notebook kraft paper, homework kraft paper, envelope special kraft paper
Food packaging should follow the principle of convenience and portability. The advantage of kraft paper's stretch resistance makes it very suitable for packaging requirements. In order to prevent the bag from being broken when the consumer takes out the food, the packaging material requires a good tensile strength. Beverage packaging requires that the production materials have a certain resistance to moisture and deformation, to prevent water absorption deformation damage.
For packaging of frozen foods, the use of high-strength materials as the packaging is also a key consideration. This material must be able to withstand the thermal expansion and contraction at low temperatures of freezing and high temperature melting to prevent deformation, distortion, wrinkling, and excessive moisture absorption. Food situation. From these perspectives, primary kraft paper is even more suitable than SBS paper.
