Plastic label | analytical plastic label printing technology

Analytical plastic badge printing process with the development of the printing industry, printing production has been more common in plastic signs, is widely applied. The following plastic badge printing process detailed analytical: plastic film sign: products carried out after completion of the printing die cutting molding; Plane plastic signs: general printing on plastic sheet, then flush type or laser cutting processing molding; Special-shaped plastic sign: molding sign text, such as specific patterns can be printed. Plastic film and plastic plates to distinguish the general with the thickness of the material for the standard: the material thickness < 0. 25 mm for the film, the thickness of the material > 0. 25 mm plate. At home can be used for plastic plate making and printing process on the surface materials are: polyethylene ( PE) And polypropylene ( PP) , PVC ( PVC) , polystyrene, PS) , acrylic - Butadiene - Styrene copolymer ( ABS) , propylene - fine Styrene copolymer ( AS) And polycarbonate ( PC) , polyester ( PET) , organic glass, PMMA) , polyurethane ( PU) , nylon ( PA) , polyamide ( PA) And so on. Plastic plate can be printed on the side or the other, there is the main method of plastic plate printing intaglio printing, flexographic printing, screen printing, thermal transfer, hot stamping, pad printing, etc. Ink is the main material of plastic plate printing production, it is formed by connecting materials, pigments, solvents and additives, form a stable colloidal dispersion system. In printing, should according to the properties of base material plastic signs, reasonably choose plastic printing ink types. 1. The first consideration, the surface of the plastic plate printing ink and the adhesion strength of the plastic base material, if improper selection, will cause the printing decoration face off. 2. Consider printing ink light resistance, due to some plastic signs placed in the outdoor environment for a long time, if the light resistance is poor, can cause products fade. 3. Want to consider the temperature resistance and cold resistance of ink, guarantee in outdoor weather conditions, there will be no ink shrinkage and cracking. 4. To consider the ink solvent resistance and acid and alkali.
