Advantages of craft paper
1. Paper is smooth and clean. No folds, wrinkles, holes, sand, etc., so as not to affect the quality of the plate.
2. Good hot pressing elasticity, high flatness, significantly improve the pressing quality and improve product yield.
3. The heat transfer performance is stable, uniform without fluctuation, and the heat transfer rate is moderate.
4. The end of the web is flat, and there are no more than 2 joints per roll.
Uses of kraft paper:
Kraft paper is used in chemical industry, machinery and other industries, especially widely used in food packaging industry. Suitable for all kinds of packaging supplies, paper bag, handbag kraft paper, color box, gift box kraft paper, printing kraft paper, notebook kraft paper, workbook kraft paper, envelope special kraft paper;
Food packaging should follow the principle of convenience and portability, kraft paper tensile strength makes it very suitable for the needs of packaging. In order to prevent consumers from breaking the bag when carrying takeaway food, the packaging material should have good tensile strength. The beverage packaging requires that the material should be moisture-resistant and deformable to prevent water absorption, deformation and damage;
For the packaging of frozen food, the use of high-strength materials as packaging is also a key consideration. Such materials must be able to withstand thermal expansion and contraction during freezing at low temperature and melting at high temperature, so as to prevent deformation, distortion, wrinkling and excessive moisture absorption and cannot hold food. From these aspects, kraft paper is even more suitable than SBS paper.
