济南手提袋印刷厂家分享手提纸袋如何模压

来源:http://www.zhongguoyingyou.com   日期:2020-04-09

  1. 用硬纸板代替压痕线

  1. Use cardboard instead of indentation line
  纸袋用纸多为铜版纸或牛皮纸,定量值小于250g/m2。一种折叠方法通常是手工折叠。因此,纸袋压痕加工一般不需要用压痕线配合钢丝,而是用硬纸板代替压痕线,具体操作如下。
  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)先清洁模切机底板,粘贴双面胶带,再铺一层厚纸板,定量约500g/m2,使其牢固附着在底板上。
  (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)使用较大的模具压力,启动模切机对厚纸板进行压痕,厚纸板经过几次压力后会出现深沟,注意纸板不能断裂。
  (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)降低模具压力,放纸,压出折痕。济南手提袋印刷制造商分享这个折痕不仅要有一定的深度,使手工折叠不容易跑线,但也不是太深,使纸折叠后损坏或破坏,或由于折痕塑性变形太重,导致未来便携式纸袋使用容易破坏,影响使用寿命。特别是在牛皮纸压痕加工中,由于牛皮纸比铜版纸更脆弱、韧性好,更能正确把握模具压力。
  (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.
  为了使纸袋容易折叠而不破裂,我们需要注意以下几点。
  In order to make the paper bag easy to fold without breaking, we need to pay attention to the following points.
  (1)垫纸应有足够的厚度;
  (1) The pad paper shall be of sufficient thickness;
  (2)成型前,将垫纸压入槽内;
  (2) Press the pad paper into the groove before forming;
  (3)压型时压力要适当;
  (3) The pressure should be appropriate when pressing;
  (4)沿纸张丝缕方向,纸张折叠性较好,模具压力较小;并且垂直于纸张丝缕方向,纸张较难折叠,可以增加局部的模压。
  (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. 纸张背面的压痕
  2. Indentation on the back of the paper
  济南手提袋印刷厂家共用折叠成型后的模具,有的压痕线是使印刷面向外折叠,有的压痕线是使印刷面向内折叠。纸袋在使用过程中更容易开裂的地方是长方形底部的四边和四条垂直线,它们是向外折叠的。为了减少手提式纸袋折叠过程中所造成的损坏,纸袋压痕应采用背压痕,即当压痕处的钢丝与纸张背面接触时,使折痕凸出到印刷表面。由于压痕线与纸张正面图像准确对准,这就要求印刷的口侧,侧规侧应与口侧相同,侧规侧成型时应与口侧一致。
  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.
  开纸法
  Paper opening method
  济南手提袋印刷制造商分享,因为有一个1厘米宽的嘴巴边小于印刷,成品也需要一条线,颜色标准,等等,所以对于一般的印刷,将比成品纸,印刷后加工,然后用裁纸刀或废纸边切模切机。如果纸袋压痕加工是用厚纸板代替压痕线,模切和压痕不适合同时进行,所以纸袋一般只用于压痕加工,而不用于模切加工。如果在压痕前用切纸机将纸张的边缘切断,会影响压痕的定位精度。济南手包印刷厂家共有如果离开模具后进行切割,由于纸张在模具中变形,不容易切割整齐。因此,一般方法是削减纸在印刷之前扩大成品的尺寸,印刷只对压痕加工后,不再需要削减或模切,以节省模具板和纸张成本,生产成本,使生产过程更有效率。
  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.
