The commonly used materials of portable paper bags are white cardboard, white paperboard, copper paperboard and kraft paper, and a few are made of special paper. First of all, the most common paper is white cardboard. Because of its strong texture, it is generally enough to bear 3 ~ 5kg in thickness of 210g. Of course, if it is heavier leather clothes or other items, the load-bearing effect of 250g white cardboard will be better. Moreover, the printing effect is also good and the price is moderate. It is generally the choice of medium and high-grade products. Coated paper is an uncommon material. Its quality is softer than white cardboard. The conventional thickness is 175g. The printing effect is the same as that of white cardboard. It also needs coating, and the price is about the same as that of white cardboard.

In recent years, white kraft paper bags of about 180 grams are often used in clothing brands. This kind of paper bag is lighter and will not be particularly large, because its load-bearing degree is not as good as white cardboard, but it is not easy to change color in printing and does not need film covering. Its price is also the highest among all kinds of materials. Of course, there are also those who use cowhide material. Its price is relatively cheaper than the coated paper below, but the printing effect is not as good as other materials.

Gray board paper and double-sided white materials are more cost-effective, which can be said to be the cheapest material among all kinds of paper. Gray board paper, as the name suggests, refers to the paper with white on one side and gray on the other. The minimum thickness is 250g, the hardness should be soft, the printing effect is similar to that of white cardboard, and it also needs to be coated. Double sided white is similar to gray board paper, but the two sides are white and the middle is gray material. The price is more expensive than gray board paper.
