envelope

kraftpaper。Use as a packaging material.The intensity is very high.It is usually yellowish-brown.Half-floating or fully floating kraft pulp is pale brown, cream or white.Quantitative 80~120g/m2. The fracture length is generally above 6,000 m.Rieration strength, rupture power and dynamic strength are high.It is mostly drum paper and also flat paper.The sulfate conifer pulp is made on the long net paper machine.Can be used as cement bag paper, envelope paper, adhesive sealing paper packaging, asphalt paper, cable protective paper, insulation paper, etc.

Craft paper is tough and water-resistant packaging paper, brown and yellow, and widely used in making paper bags, envelopes, workbooks, record covers, files, and sandpaper.The quantitative range is 80 g / m 2 to 120 g / m 2, distinguishing between coiled paper and single-sided, double-sided light and stripes.The main quality requirements are flexible and strong, with high rupture resistance, and can withstand greater tension and pressure without rupture.Craft paper has high tension, single, double, stripes, no, etc.It is mainly used for wrapping paper, envelopes, paper bags and press roller lining.

Craft paper is used in the chemical industry, machinery and other industries, especially widely used in the food packaging industry.

Use of kraft paper: kraft paper is widely used in a variety of packaging supplies, paper bag, handbag kraft paper, color box, gift box kraft paper, printed kraft paper

Print kraft paper, notebook kraft paper, workbook kraft paper, special kraft paper for envelopes

Food packaging should follow the principle of convenience, portable, kraft paper anti-tensile advantage makes it very suitable for packaging needs.To prevent consumers from pulling off the bags when carrying the extra food, the packaging materials require good tensile strength.Beverage packaging requires that the making materials have a certain anti-humidity without deformation ability, to prevent water absorption deformation and damage.

For the packaging of frozen food, the use of high strength material as the key to consider, this material must be able to withstand the thermal expansion and cold contraction when low temperature freezing and high temperature melting, to prevent deformation, distortion, wrinkle, and excessive moisture absorption to hold food.In these ways, raw kraft paper works even better than SBS paper.
