手提袋印刷与模压的制作流程

1.用厚纸板代替压痕线制作手提纸袋的纸张大多是定量小于250g/m2的铜版纸或牛皮纸等,后折叠成型一般采用手工折叠方式。因此,纸袋的压痕加工一般也不需要用压痕线来配合钢线进行,而是用厚纸板代替压痕线使用,具体操作如下。

1., the use of thick cardboard instead of indentation line to produce paper for handbags is mostly less than 250g/m2 of coated paper or kraft paper. Finally, folding is usually done by manual folding. Therefore, the indentation processing of the paper bag generally does not need to use the indentation line to match the steel wire, but instead of the indentation line using the thick cardboard, the concrete operation is as follows.

(1)先将模切机的底板清洗干净,粘上双面胶,再铺上一层定量约为500g/m2的厚纸板,使它牢固地粘在底板上。

(1) first die-cutting machine floor clean, sticky glue, covered with a layer of quantitative approximately 500g/m2 thick cardboard, so that it is firmly adhered on the bottom board.

(2)采用较大的模压压力,开动模切机对厚纸板进行压痕,厚纸板经过多次重压后会出现较深的沟痕,要注意不能将纸板压裂。

(2) with larger mould pressure and die-cutting machine, the thick cardboard will be indentation. After thick pressing, there will be deeper groove marks.

(3)调小模压压力,放入纸张,压出折叠痕迹。这种折痕既要有一定的深度,使手工折叠时不易跑线,但也不能太深,使纸张被压破或折叠后破裂,或者由于折痕处塑性变形过重,导致手提纸袋在以后的使用中容易破裂,影响使用寿命。尤其是在对牛皮纸进行压痕加工时,由于牛皮纸较脆,韧性不如铜版纸,更要恰当地掌握模压压力。

(3) adjust the pressure of small mold pressure, put the paper, and press out the folding marks. This crease not only have a certain depth, the hand is not easy when folded line running, but not too deep, so that the paper be crushed or folded after rupture, or due to plastic deformation folds too easily lead to rupture of the use of portable paper bag in the future, affect the service life. Especially in the indentation processing of the kraft paper, because the kraft paper is more brittle and the toughness is not as good as the copper plate, it is more appropriate to master the pressure of the molding.

为了使手提纸袋既好折,又不至于压裂,需要注意以下几点。

In order to make the hand-held paper bags both good and not fractured, we need to pay attention to the following points.

(1)垫纸要具有足够的厚度;

(1) the pad should have enough thickness;

(2)模压前先将垫纸压出沟痕;

(2) molded pad paper before a groove;

(3)正式模压时的压力要适当;

(3) the pressure to be formally pressed should be appropriate;

(4)沿着纸张的丝缕方向,纸张比较好折,模压压力可小些;而垂直于纸张丝缕方向,纸张比较难折,可在局部增加模压压力。

(4) along the silk thread direction of paper, the paper is better folded, the molding pressure is smaller, and the paper is difficult to fold perpendicular to the direction of the silk thread, and it can increase the molding pressure locally.
