The invention also discloses a preparation method of the aluminum foil for food and medicine packaging. The aluminum foil for packaging food and medicine has a simple structure, can be used for carrying out UV flexographic printing or UV letterpress printing on the aluminum foil, and the printing ink can not fall off through a tape test after printing, so that the aluminum foil is beneficial to environmental protection, and has good printing effect, bright color and low loss of printing materials.
Description
Technical field
The present invention relates to a kind of food and medicine packing, particularly a kind of food and medicine Packaging Aluminum Foil; The invention still further relates to this manufacturing aluminum foil.
Background technology
China just introduces flexographic printing technology in the seventies initial stage, through technical innovation repeatedly, has established the status in the packages printing field so far.Up to nineteen fifty-two, on the print session that Stockholm, SWE is held, negate that the participant agrees unanimously and changes Flexography into to the address of aniline printing.The implication that it is discussed was at that time, because photoresist is rudiment, the appearance of polyethylene, polyester, the carrier that is made for stock greatly increases, so the application approach high resilience of Flexography can be suitable for the printing of various uses, so life is this name, domestic translator comes for flexographic printing has passed from literal literal translation under the situation of the background of not understanding it, and is so far sanctified by usage.Arrived twentieth century first half, be used after the bright nonabsorbable packing of the printthrough glass paper, it uses expansion rapidly, relates to polyethylene and various film of synthetic resin, as the printing process of packing, lays a good foundation in European and American countries.Japan then just introduces this technology from earlier 1900s, be used for printing fluting board, paper bag etc., different with the America and Europe, originally never be applied to flexible packing material and carton field, reason has two, the one, not satisfied to the quality of flexographic printing, the 2nd, introduce gravure already and offset printing has satisfied demand.Recently, along with the environment of flexographic printing technology has been caught up with gravure and offset printing, so the speed of expanding is accelerated.
Relief printing with the longest history the most universal, space of a whole page image and literal projection are accepted printing ink, and the part that falls in is not accepted printing ink, and when version and letterweight were tight, printing ink will be imprinted on the paper.Printing plate mainly contains: type form, stereotype, photo zincography, copper coin, photopolymer plate etc.Some books and periodicals, bill, envelope, business card etc. are also using relief printing; For example need special processing: gold stamping, silver-colored, indentation is protruding etc. generally also used relief printing.
UV is the abbreviation of English Ultraviolet Rays, i.e. ultraviolet light.Ultraviolet ray (UV) is that naked eyes are invisible, is one section electromagnetic radiation beyond the visible purple light, and wavelength is in the scope of 10～400nm.The UV ink printing has following characteristics: 1. instantaneous solidification; Can in seconds solidify behind the UV ink printing, obviously improve production efficiency; Particularly aspect tin graphed sheet, utilize this characteristics, can omit the baking dry run.And drying equipment is simple, saves space.2. environmental protection; UV printing ink does not use solvent, and exhaust emission material not during curing can improve operating environment, air conservation.Because do not need solvent processing equipment and special environmental protecting device, can reduce equipment investment greatly simultaneously.3. photopolymerization drying mode; UV printing ink or UV gloss oil, only otherwise the contact ultraviolet ray just can not solidify, from this aspect, its keeping is fairly simple.And photopolymerization reaction and volatile dry are different, are a kind of chemosettings, and other printing ink ink film hardness height of film forming hardness ratio are applicable to the printing that film hardness is had relatively high expectations.4. high-quality; The glossiness height of UV printed matter has good rub resistance, solvent resistance, resistance to effect of heat etc., the product specification height.In packages printing, be extensive use of.5. save the energy; UV solidifies little power consumption, saves the energy.
In the prior art, printing on food and medicine Packaging Aluminum Foil material all is to adopt organic solvent type printing ink, and this is not only bad for environmental protection, and the colored printing effect is undesirable, the energy consumption height.Though UV flexographic printing or UV relief printing have plurality of advantages, but it fails to use on food and medicine Packaging Aluminum Foil material, reason just is that printing ink easily comes off, and also can't address this problem so far in the prior art when aluminium foil surface carries out the UV printing.
Summary of the invention
Technical matters to be solved by this invention is at the deficiencies in the prior art, and a kind of food and medicine Packaging Aluminum Foil new, that can carry out UV flexographic printing or UV relief printing thereon is provided.
Another technical matters to be solved by this invention provides a kind of preparation method of aforesaid food and medicine Packaging Aluminum Foil.
