Kraft Paper

As an expert kraft paper manufacturer, we make pre-stressed kraft paper by combining paper pulp with warp and weft yarns. The yarns decide the strength of the paper, while the pulp serves as the auxiliary filling material. This papermaking method is similar to the process of putting pre-stressed steel, which means the strength of the paper can be easily readjusted by changing the texture, specification and density of the yarns. The performance and properties of the paper can be changed by choosing different types of pulp. The paper is a combination of different properties of paper and the strength of the cloth, and its strength is 3 to 4 times higher than ordinary kraft paper. It is commonly used for lightweight packaging, improves the performance, reduces production costs and saves resources, protecting the environment.

Just like ordinary kraft paper, our pre-stressed kraft paper can be processed through printing, laminating and slitting.

Our kraft paper comes in different size selections, and two major dimensions through a sheet type or roll type. The width of roll paper is 2.6m, while the size of the sheet paper is divided into 787 x 1092mm and 889 x 1194 mm.

We have a huge production capacity, with a daily capacity reaching 200 tons, easily meeting market demands. We are also consistently improving upon our existing capacity to meet changing market conditions.

Pre-stressed kraft paper is useful in a variety of bags, including shopping bags, flour sacks, food packing bags, and architectural wall seam sealing tapes. Packing bags and shopping bags made from pre-stressed kraft paper have a significantly higher bond than similar kraft paper sacks, ensuring the package safety and preventing broken bags. This paper can also be used or packaging food as it has passed third party testing for food hygiene requirements. Made of a high bond pre-stressed kraft paper, the wall seam sealing tape prevents cracked walls from cracking again after being coated in putty, ensuring the wall remains neat.

Customers from food, packaging, and clothing industries have all ordered packing materials and decoration engineering materials from us. We can also develop and process packing bags and finishing material finished products to meet specific customer requirements. Shanghai ZhiZheng will undertake every effort to satisfy each customer need.

Shopping bags are traditionally made of wood pulp paper. The strength of the paper depends on the fiber strength of the wood pulp. Paper used in shopping bags must be high intensity and strong enough to hold heavy loads. This is why many turn to pre-stressed craft paper as an alternative for shopping bags. Pre-stressed kraft paper is clean, sanitary, strong, low cost and environmentally friendly.

Compared to all-wood paper, pre-stressed kraft paper improves longitudinal rip and tensile strength in both directions up to 3 times, enhances elongation in both direction up to 6 times, and increases the vertical and lateral tensile energy absorption value up to 8 times. Pre-stressed kraft paper also has an excellent fastness and is extremely strong.

Made from pre-stressed kraft paper, wall seam sealing tape features an excellent air permeability, environmental friendliness, crack resistance, moisture resistance, high tensile strength, great stiffness, and its strong, light weight and easy to use. It kraft paper wall seam sealing tapes work better than traditional seam sealing tapes and caulking compounds, as it has a higher adhesive force and won't begin to peel off in layers.
