Bags made six important tips, barriers to build high quality packaging!

Bags are reviewed in this paper. the production process of a few little skill, such as ink distribution skills, plate safety tips, curing discriminant tips, etc. Make production enterprises in order to understand how the packing bag of high quality. A small tip 1, ink distribution, lack of what color addition what color ink. For example, in the orange ink, visual short red, can increase a few red. 2, remove a bullish in hue hue, the principle of complementary color correct use. In the produce practice, in order to make the white more white, sometimes in white ink to add trace of ultramarine blue ( About 1%) To get rid of the white in the yellow can be arrived at; And as long as attend a handful of titanium cyanine in black ink, can eliminate the yellow colour in black ink. 3, light ink, want to take part in the color in white ink, and don't take part in the color white ink, white ink, strong hiding power, attended many will soon weaken the color; And when making dark ink, it must be put in black ink to add to the color, must not put the color in black ink, because the black ink color force strong, a bit not careful and attended many, is demand for quite a few color to adjust the color. 4, query the color sample, it is best under the standard light source, and to choose the same floor. Second, tip 1 plate equipment, check the network cable, layout, to ensure that no dent, no scratch, no phenomenon of chromium. Careful installed version of the direction and orientation, to ensure that the vertical version of roots right in. 2, plate should be especially careful to check the cap and plug in the clean, prevent the error caused by foreign body equipment. Should be careful operation, prevent the layout of bruising. 3, low-speed operation, have to check the version of the roll without deviation, is the roll imbalance phenomenon caused by the device error. Three, manual addressing tip color code for the longitudinal line of reverse time, choose the left a group of signals; Color scale vertical line of reverse time, choose a new set of Numbers of most the right side. Four discriminant tip 1, curing time, curing is refers to the succession of curing time, accumulative time after not have cure, usually there is no need to wait the main agent and curing agent complete response after radical cure, but some emergency produce of retort pouch, namely customer to use immediately, demand cure thoroughly, although the two methods produce the packing bag of peel strength difference is not big, but the difference in temperature resistance and corrosion resistance. 2, according to the situation after cure thoroughly adhesives, can distinguish ratio of curing agent and the principal agent whether appropriate, if the adhesive is not stem situation, indicating the content of curing agent, adhesive and hard, brittle, indicating the content of curing agent on the high side. Five, check to see if the tension when matching tip down, in the process of composite in the use of the blade on the composite film winding delimit a cross, ideally composite film still insist on flat after the cut. Assumed composite film bend in one direction, then the tension of the film is too big, should be appropriate drop increase the tension of the film or another film tension. Six, when the bag heat sealing temperature set tip when heat sealing temperature setting also needs to consider the thickness of the heat sealing film, heat sealing and the influence of different structural elements such as composite materials, such as PE80 monolayer film heat sealing temperature is 120 ℃, the general heat sealing cloth block on the temperature around 40 ~ 60 ℃, PET12 / A17, cut off to temperature is 20 ℃, NY15 blocks on the temperature of 15 ℃, namely because of the effect of material structure and heat sealing, eventually PET12 / A17 / PE80 heat sealing set temperature is 185 ℃, NY15 / PE80 heat sealing temperature is 180 ℃.
