The commonly used materials for portable paper bags include: white cardboard, white board paper, copper board paper, kraft paper, and a small amount of special paper. The gram weight of white cardboard is applicable from 210-300 grams, the gram weight of white board is applicable from 180-350 grams, the gram weight of coated paper is applicable from 200-300 grams, and the gram weight of kraft paper is applicable from 158-280 grams.
First of all, the most common type of paper is white cardboard. Due to its strong texture, a thickness of 210 grams is usually sufficient to bear 3-5 kilograms. Of course, if it is heavier leather clothing or other items, using a white card of 250 grams will have a better bearing effect, and the printing effect is also good. The price is moderate, making it generally a choice for mid to high-end products. Coated paper is an uncommon material that is softer in quality than white cardboard, with a conventional thickness of 175 grams. The printing effect is the same as that of white cardboard, and it also requires film covering, with a price similar to that of white cardboard.
Grey board paper and double-sided white materials are more cost-effective, and can be said to be the cheapest material among the various types of paper. Grey board paper, as the name implies, refers to paper with one side white and one side gray, with a minimum thickness of 250 grams, a softer hardness, and a printing effect similar to that of white cardboard, which also requires film covering. Double sided white is similar to gray board paper, except that both sides are white and the middle is made of gray material, which is more expensive than gray board paper.
In recent years, about 180 grams of white kraft paper bags have often been used for clothing brands. This type of paper bag is more lightweight and not particularly large, because it has less weight bearing than white cardboard, but it is not easy to change color when printing, and does not require film covering. Its price is also the highest among various materials. Of course, there are also materials made of cowhide, which is relatively cheaper than the coated paper below, but the printing effect is not as good as other materials.
