一、按材質可分為：白卡紙，白色牛皮紙，銅版紙，牛皮，以及少量的特殊紙張。

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、白卡紙：白卡紙結實厚實，具有較高的挺度、耐破度和平滑度，紙面光滑。常用的厚度是250-300g白卡紙，更多的是250手提袋專用白卡紙。白色紙板和印刷制成的紙袋，色彩飽滿，質地良好，是定制手提袋的首要選擇。

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、銅版紙：它的特點之處在于，紙張表面非常光滑平整，白度、光潔度高，光澤度好。也使得印刷出來的圖形和圖片具有立體感。常用厚度128g-300g。銅版紙的印刷效果和白卡紙一樣，顏色飽滿明亮。與白紙板相比，它的剛度不如白紙板。承重能力不行，易破損

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

、白色牛皮紙：白色牛皮紙耐破度高，韌性好，強度高，彩色圖像穩(wěn)定。根據(jù)相關法規(guī)，超市限制使用塑料袋，國外和歐美提倡使用環(huán)保紙袋，嚴格控制塑料污染，塑料袋將被環(huán)保紙袋取代。白色牛皮紙市場前景看好。采用100%純木漿制成，環(huán)保無毒，可回收利用。白色牛皮紙韌性好，不需要覆膜，所以廣泛用于制作環(huán)保服裝手袋和購物袋。常用120g-200g的白色牛皮紙，紙張沒有亮度和光澤度，所以白色牛皮紙不適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.

、牛皮紙：也叫天然牛皮紙。它具有高拉伸強度、高韌性(通常為棕黃色)、高撕裂強度、斷裂強度和動態(tài)強度，廣泛用于購物袋、信封等。常用牛皮紙，厚度120g-300g。牛皮紙在印刷一般適用于單色或雙色、不復雜的文稿，與白卡紙、白牛皮紙相比，黃牛皮紙紙袋的價錢低。

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.

、黑色紙板：是一種特殊的紙，兩面都是黑色的。黑色紙板的特點是一種很好的紙，深黑色，結實而厚實，耐折性好，表面光滑，挺度好，抗拉強度好，耐破度高。常用黑紙板，厚度120g-350g。因為黑紙板里外黑，所以在印刷不能上色，只適合燙金、銀燙金等工藝。做出來的包包也很好看。

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：包括檔案袋、信封、服裝袋、食品袋、購物袋、禮品袋和酒袋。不同的用途，設計的規(guī)格尺寸，包括紙袋的厚度，都有很多要求，所以要根據(jù)實際情況定制，紙張都可回收材料。

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. Paper can be recycled materials.
