Description
Technical field
The present invention relates to a kind of printing-ink and preparation method thereof, particularly a kind of food packaging luminescent ink and preparation method thereof.
Background technology
Modern food form is varied, and food product pack form is also varied.The main packaged form of current food has Plastic Bottle, metal tin, paper-based composite material packaging, plastics bag, vial, dixie cup, plastic cup etc.The Upholstering design pattern of food-drink outer packaging comprises goods marks, the name of an article, formula for a product, decorative pattern etc. that nutritional information table is relevant with product, bright in luster eye-catching in packaging Decoration Design, adopts the techniques such as flexo, offset printing, gravure, silk screen printing to print usually.But in the environment that light is more dim, such as concert, bar, party, or under the night environment such as open deck, the packing ratio of existing food packaging inks printing is adopted comparatively to lack individuality, also eye-catching not, word and the pattern that especially can embody selling point cannot embody in this dim environment, can not express and transmit the information of product.
The luminescent ink of prior art can be luminous in dim environment, the individual character of exhibiting product and highlighting in dim environment.But luminescent ink is mainly used in the anti-counterfeit package of Valued Securities, certificate, stamp and name brands, also have for printing window display, collision bumper protect shelves, pictorial poster (placard), outdoor advertising field.This luminescent ink contains luminescent powder, absorbs sunlight 10-30 minute by day, just can be automatic continuous luminous more than 10 hours.Wherein benzene dissolubility Chlorinated Polypropylene III ink is the ink that current use is the widest, be mainly used in food plastic packages printing at present, and such ink is used for BOPP(Biaxially oriented polypropylene film (BOPP)) material.Although the printability of this ink is excellent, post-press finishing performance is good, fast drying, and because the relative toxicity of toluene is comparatively large, the residual solvent value of printed matter is higher; Again due to the poor heat stability of Chlorinated Polypropylene III, in production and storage process, easily discharge chlorine and form hydrogenchloride, making ink be stronger acidity, serious corrosion is produced to printing plate cylinder.People have recognized that benzene soluble ink can damage the ozone layer, inadequate environmental protection.And this type of ink in use also can work the mischief to the health of workman, be unfavorable for safety in production; The dissolvent residual of ink in packing articles, can pollute the food in packaging under certain condition.Therefore, the food product pack luminescent ink of development safety, environmental protection becomes problem demanding prompt solution.
Summary of the invention
The object of this invention is to provide a kind of food packaging luminescent ink, not only there is the feature of use safety and environmental protection, and can not corroded by proterctive equipment.
