Kraft paper is a tough, water-resistant packaging paper with a brownish-yellow color and a wide range of uses. It is often used to make paper bags, envelopes, workbooks, record sleeves, files and sandpaper. The main quality requirements are flexibility and strength, high burst resistance, and ability to withstand greater tension and pressure without breaking. Kraft paper has a high tensile strength, such as single gloss, double gloss, stripes, and no grains. Mainly used for packaging paper, envelopes, paper bags, etc. and printing press drum linings, etc.

advantage:

1. The paper is flat and clean. No folds, wrinkles, holes, sand, etc., so as not to affect the quality of the platen.

2. The hot pressing has good elasticity and high flatness, which can significantly improve the quality of pressing and increase the rate of finished products.

3. The heat transfer performance is stable, uniform and no fluctuation, and the heat transfer rate is moderate.

4. The end of the roll paper is flat, no more than 2 joints per roll.

Kraft paper is used in various industries such as chemicals and machinery, especially in the food packaging industry.

Kraft paper use: Kraft paper is widely used in various packaging supplies, such as paper bags, handbag kraft paper, color boxes, gift box kraft paper, printing kraft paper, notebook kraft paper, workbook kraft paper, and special kraft paper for envelopes.

For the packaging of frozen food, the use of high-strength materials as packaging is also the key consideration. This material must be able to withstand the thermal expansion and contraction during low-temperature freezing and high-temperature melting, and prevent deformation, distortion, wrinkling, and excessive moisture absorption. The condition of the food. From these aspects, the original color kraft paper is even more suitable than SBS paper.
