1. Use cardboard instead of indentation line

　　紙袋用紙多為銅版紙或牛皮紙，定量值小于250g/m2。一種折疊方法通常是手工折疊。因此，紙袋壓痕加工一般不需要用壓痕線配合鋼絲，而是用硬紙板代替壓痕線，具體操作如下。

　　The paper used for paper bag is mostly coated paper or kraft paper, and the quantitative value is less than 250G / m2. The last method of folding is usually hand folding. Therefore, the paper bag indentation processing generally does not need to use indentation line with steel wire, but uses cardboard instead of indentation line, the specific operation is as follows.

　　(1)先清潔模切機底板，粘貼雙面膠帶，再鋪一層厚紙板，定量約500g/m2，使其牢固附著在底板上。

　　(1) First, clean the bottom plate of the die-cutting machine, paste double-sided tape, and then lay a layer of thick cardboard, with a ration of about 500g / m2, so that it firmly adheres to the bottom plate.

　　(2)使用較大的模具壓力，啟動模切機對厚紙板進行壓痕，厚紙板經過幾次壓力后會出現深溝，注意紙板不能斷裂。

　　(2) Start the die-cutting machine to indent the thick cardboard with a larger mold pressure. After several times of pressure, the thick cardboard will appear deep groove. Pay attention that the cardboard cannot be broken.

　　(3)降低模具壓力，放紙，壓出折痕。濟南手提袋印刷制造商分享這個折痕不僅要有一定的深度,使手工折疊不容易跑線,但也不是太深,使紙折疊后損壞或破壞,或由于折痕塑性變形太重,導致未來便攜式紙袋使用容易破壞,影響使用壽命。特別是在牛皮紙壓痕加工中，由于牛皮紙比銅版紙更脆弱、韌性好，更能正確把握模具壓力。

　　(3) Reduce mold pressure, put paper, press out crease. Jinan handbag printing manufacturer shares that the crease should not only have a certain depth, so that the manual folding is not easy to run, but also not too deep, which causes the paper to be damaged or damaged after folding, or because the plastic deformation of the crease is too heavy, the future use of portable paper bags is easy to be damaged, affecting the service life. Especially in the process of kraft paper indentation, because kraft paper is more fragile and tough than copperplate paper, it can grasp the mold pressure more correctly.

　　為了使紙袋容易折疊而不破裂，我們需要注意以下幾點。

　　In order to make the paper bag easy to fold without breaking, we need to pay attention to the following points.

　　(1)墊紙應有足夠的厚度;

　　(1) The pad paper shall be of sufficient thickness;

　　(2)成型前，將墊紙壓入槽內;

　　(2) Press the pad paper into the groove before forming;

　　(3)壓型時壓力要適當;

　　(3) The pressure should be appropriate when pressing;

　　(4)沿紙張絲縷方向，紙張折疊性較好，模具壓力較小;并且垂直于紙張絲縷方向，紙張較難折疊，可以增加局部的模壓。

　　(4) Along the paper filament direction, the paper folding is better, the mold pressure is smaller; and perpendicular to the paper filament direction, the paper is more difficult to fold, can increase local molding.

　　2. 紙張背面的壓痕

　　2. Indentation on the back of the paper

　　濟南手提袋印刷廠家共用折疊成型后的模具，有的壓痕線是使印刷面向外折疊，有的壓痕線是使印刷面向內折疊。紙袋在使用過程中更容易開裂的地方是長方形底部的四邊和四條垂直線，它們是向外折疊的。為了減少手提式紙袋折疊過程中所造成的損壞，紙袋壓痕應采用背壓痕，即當壓痕處的鋼絲與紙張背面接觸時，使折痕凸出到印刷表面。由于壓痕線與紙張正面圖像準確對準，這就要求印刷的口側，側規側應與口側相同，側規側成型時應與口側一致。

　　Jinan handbag printing factory shares the mold after folding, some of the indentation lines make the printing face outward folding, some of the indentation lines make the printing face inward folding. The four sides and four vertical lines at the bottom of the rectangle are the most likely places for the paper bag to crack in use, and they are folded outwards. In order to reduce the damage caused by the folding process of the portable paper bag, the back indentation should be used for the paper bag indentation, that is, when the steel wire at the indentation contacts the back of the paper, the crease will protrude to the printing surface. As the indentation line is accurately aligned with the front image of the paper, it is required that the side of the side gauge should be the same as the side of the mouth, and the side gauge should be the same as the side of the mouth when forming.

　　開紙法

　　Paper opening method

　　濟南手提袋印刷制造商分享,因為有一個1厘米寬的嘴巴邊小于印刷,成品也需要一條線,顏色標準,等等,所以對于一般的印刷,將比成品紙,印刷后加工,然后用裁紙刀或廢紙邊切模切機。如果紙袋壓痕加工是用厚紙板代替壓痕線，模切和壓痕不適合同時進行，所以紙袋一般只用于壓痕加工，而不用于模切加工。如果在壓痕前用切紙機將紙張的邊緣切斷，會影響壓痕的定位精度。濟南手包印刷廠家共有如果離開模具后進行切割，由于紙張在模具中變形，不容易切割整齊。因此,一般方法是削減紙在印刷之前擴大成品的尺寸,印刷只對壓痕加工后,不再需要削減或模切,以節省模具板和紙張成本,生產成本,使生產過程更有效率。

　　Jinan handbag printing manufacturer shares that because there is a 1 cm wide mouth edge smaller than printing, the finished product also needs a line, color standard, etc., so for general printing, it will be processed after printing, and then cut the die-cutting machine with a paper cutter or waste paper. If the paper bag indentation processing is to use cardboard instead of indentation line, die-cutting and indentation are not suitable for simultaneous processing, so the paper bag is generally only used for indentation processing, not die-cutting processing. If the edge of the paper is cut off by the paper cutter before the indentation, the positioning accuracy of the indentation will be affected. Jinan handbag printing factory has cut after leaving the mold, because the paper is deformed in the mold, it is not easy to cut neatly. Therefore, the general method is to reduce the size of paper before printing and expand the size of finished products. After the indentation processing, there is no need to cut or die-cut, so as to save the cost of die plate and paper, production cost and make the production process more efficient.
