Non-woven bag printing process Non-woven fabric printing is generally divided into four types: ink screen printing, ink machine printing, thermal transfer printing and film covering printing.
The printing color is single, and the printing area is not large (about 20%). Generally, ink screen printing is used, and the printing cost is low. The cost of one color is 5-6 cents, which is the most environmentally friendly. The printing color is medium, the printing area is large, the requirements for environmental protection are not high, and the cloth surface is bright (such as white, yellow or light green non-woven fabrics), so the printing cost is medium, the printing price is low, and the cost of one color is 2-3 cents, which has the disadvantage of not being environmentally friendly; Thermal transfer printing can be used for printing with rich colors and small printing area, and the printing price is relatively high, about 12 yuan/square meter; The requirement for printing color is very realistic. The whole-page printing basically adopts film covering printing (that is, the pattern is printed on OPP film and then compounded with non-woven fabric), which has the advantages of environmental protection and beautiful images, but the disadvantages are high printing cost, high printing film covering cost and the unit price of printing cost is 0. 12 yuan /cm2 (if the plate making price is multiplied by the plate surface area instead of the actual printing area, because the plate surface area is larger than the actual printing area).
There are two kinds of non-woven bag forming: one is bag cutting by ultrasonic automatic machine: the work includes bag cutting, punching and bag throwing; Bag cutting is generally divided into 5/6 points (including punching), and sling is generally 15 points/piece. 2. Handmade: Its workmanship includes sewing, nailing and crossing. For example, the sewing price of ordinary three-dimensional bags is generally 0.32 yuan/piece, the stitching price is 4 cents (including buttons), and the crossing price is 8 cents. If there are special requirements, it needs to be calculated separately.
