Kraft paper is a special type of paper that is commonly used for packaging and printing. Compared to ordinary paper, kraft paper is stronger and can withstand more pressure and friction. So, why is kraft paper stronger than regular paper?
First of all, the raw material of kraft paper is usually wood fiber, which is inherently tough and can withstand large tensile forces and pressures. Ordinary paper, on the other hand, is usually made of grass fibers, which are more fragile than wood fibers.
Secondly, the production process of kraft paper is also different from that of ordinary paper. Kraft paper often needs to be layered and pressed in multiple layers during the manufacturing process, making the structure of the paper more compact and strong. In contrast, the production process of ordinary paper is relatively simple, without much pressing and processing, so its structure is relatively loose.
In addition, the surface of kraft paper is also rougher than that of regular paper. This rough surface can increase the friction of the paper, making it more resistant to wear and pressure. On the other hand, the surface of ordinary paper is relatively smooth and susceptible to abrasion and cracking. To sum up, the reason why kraft paper is stronger than ordinary paper is mainly due to the toughness of its raw material wood fiber and the particularity of the production process. The combination of these factors makes kraft paper have better pressure resistance, abrasion resistance and water resistance, so it is widely used in packaging, printing and other occasions that need to withstand large pressure and friction.
