Another kind is chloric ethylene vinyl acetate copolymer resin/c dilute acid resin as the main composition of the alu foil special ink, its characteristic is colour and lustre bright-coloured, high concentration, with particularly strong adhesion of the Bare aluminium alloy foil for medical ptp, has the good transparency, but because of when used in gravure printing, the solvent volatility, medicinal inhibits PTP alu foil used for table cause intaglio roller inking hole when printing ink hard, deposition, Produce paste version phenomenon. Therefore, it is necessary to pretreatment the deposition of ink freezing, the method is to deposition of ink freezing stirring or increasing the temperature (water bath). If the storage time of ink is too long, ink will appear deposition, resulting in ink resin solution, lower layer of pigment, the upper color is light, the lower color is dark, should also be used after mixing evenly.
When the viscosity of ink with a large amount of diluent dilution, should be added to the diluent side stirring, so that the diluent evenly distributed in the whole ink. Measurement of supplies in about 20-30 seconds. Indoor temperature and humidity, ink concentration has an impact, it is best to use ink concentration detector to determine the amount of solvent, and according to the temperature and humidity changes, every certain time to determine the concentration of ink. When using gravure printing to print alu foil products, the ink concentration is too low, which will cause the color of printed words and patterns is not bright. Ink concentration is too high, the diagram will produce cracking phenomenon, not only a waste of ink, but also easy to cause the printing surface is not smooth, not beautiful.
PTP alu foil adhesive is coated in the inside of the alu foil, its role is to make alu foil and medicinal PVC hard sheet can be firmly hot pressed, so that the drug in the plastic hard sheet bubble cover is separated from the outside world, to achieve the purpose of drug sealing. In the process of heat sealing, the adhesive layer is activated by hot pressing, so as to firmly adhere to the PVC plastic sheet as a whole, which requires the adhesive layer and PVC resin should have good heat sensitivity and compatibility with the base material.
