一、按材质可分为：白卡纸，白色牛皮纸，铜版纸，牛皮，以及少量的特殊纸张。

1、 According to the material, it can be divided into: white cardboard, white kraft paper, copperplate paper, kraft paper, and a small amount of special paper.

1、白卡纸：白卡纸结实厚实，具有较高的挺度、耐破度和平滑度，纸面光滑。常用的厚度是250-300g白卡纸，更多的是250手提袋专用白卡纸。白色纸板和印刷制成的纸袋，色彩饱满，质地良好，是定制手提袋的首要选择。

1. White cardboard: White cardboard is sturdy and thick, with high stiffness, durability, and smoothness, and a smooth paper surface. The commonly used thickness is 250-300g white cardboard, with more emphasis on 250g white cardboard for handbags. White cardboard and printed paper bags, with full colors and good texture, are the primary choice for customizing handbags.

2、铜版纸：它的特点之处在于，纸张表面非常光滑平整，白度、光洁度高，光泽度好。也使得印刷出来的图形和图片具有立体感。常用厚度128g-300g。铜版纸的印刷效果和白卡纸一样，颜色饱满明亮。与白纸板相比，它的刚度不如白纸板。承重能力不行，易破损

2. Copperplate paper: Its characteristic is that the surface of the paper is very smooth and flat, with high whiteness, smoothness, and good glossiness. It also gives the printed graphics and images a three-dimensional feel. Commonly used thickness is 128g-300g. The printing effect of copperplate paper is the same as that of white cardboard, with full and bright colors. Compared to white cardboard, its stiffness is not as good as white cardboard. Poor load-bearing capacity and susceptibility to damage

、白色牛皮纸：白色牛皮纸耐破度高，韧性好，强度高，彩色图像稳定。根据相关法规，超市限制使用塑料袋，国外和欧美提倡使用环保纸袋，严格控制塑料污染，塑料袋将被环保纸袋取代。白色牛皮纸市场前景看好。采用100%纯木浆制成，环保无毒，可回收利用。白色牛皮纸韧性好，不需要覆膜，所以广泛用于制作环保服装手袋和购物袋。常用120g-200g的白色牛皮纸，纸张没有亮度和光泽度，所以白色牛皮纸不适合印刷油墨含量太多。

White kraft paper: White kraft paper has high tear resistance, good toughness, high strength, and stable color images. According to relevant regulations, supermarkets are restricted from using plastic bags, while foreign countries and Europe and America advocate the use of environmentally friendly paper bags and strictly control plastic pollution. Plastic bags will be replaced by environmentally friendly paper bags. The market prospects for white kraft paper are promising. Made of 100% pure wood pulp, environmentally friendly, non-toxic, and recyclable. White kraft paper has good toughness and does not require lamination, so it is widely used to make environmentally friendly clothing handbags and shopping bags. White kraft paper with a weight of 120g-200g is commonly used, but the paper lacks brightness and glossiness, so white kraft paper is not suitable for printing with too much ink content.

、牛皮纸：也叫天然牛皮纸。它具有高拉伸强度、高韧性(通常为棕黄色)、高撕裂强度、断裂强度和动态强度，广泛用于购物袋、信封等。常用牛皮纸，厚度120g-300g。牛皮纸在印刷一般适用于单色或双色、不复杂的文稿，与白卡纸、白牛皮纸相比，黄牛皮纸纸袋的价钱低。

Kraft paper: also known as natural kraft paper. It has high tensile strength, high toughness (usually brownish yellow), high tear strength, fracture strength, and dynamic strength, and is widely used in shopping bags, envelopes, etc. Commonly used kraft paper, with a thickness of 120g-300g. Kraft paper is generally suitable for printing monochrome or two-color, uncomplicated documents. Compared with white cardboard and white kraft paper, yellow kraft paper bags have a lower price.

、黑色纸板：是一种特殊的纸，两面都是黑色的。黑色纸板的特点是一种很好的纸，深黑色，结实而厚实，耐折性好，表面光滑，挺度好，抗拉强度好，耐破度高。常用黑纸板，厚度120g-350g。因为黑纸板里外黑，所以在印刷不能上色，只适合烫金、银烫金等工艺。做出来的包包也很好看。

Black cardboard: It is a special type of paper with black on both sides. The characteristics of black cardboard are that it is a very good type of paper, dark black, sturdy and thick, with good folding resistance, smooth surface, good stiffness, good tensile strength, and high burst resistance. Commonly used black cardboard, with a thickness of 120g-350g. Because the inside and outside of the black cardboard are black, it cannot be colored during printing and is only suitable for processes such as hot stamping and silver hot stamping. The bag made is also very beautiful.

三、按照用途的不同：包括档案袋、信封、服装袋、食品袋、购物袋、礼品袋和酒袋。不同的用途，设计的规格尺寸，包括纸袋的厚度，都有很多要求，所以要根据实际情况定制，纸张都可回收材料。

3、 According to different purposes: including file bags, envelopes, clothing bags, food bags, shopping bags, gift bags, and wine bags. There are many requirements for different purposes, design specifications and sizes, including the thickness of paper bags, so they need to be customized according to actual situations.
