Description
Technical field
The present invention relates to printing process, be specifically related to the color printing method of the composite corrugated carton of a kind of polypropylene screen.
Background technology
Corrugated case is that corrugated board is made through cross cutting, impression, nail case or stick box, is a kind of most widely used packing articles.
In recent years, domestic corrugated case production is that couch board is shaped to corrugated board by make-up machine, with amylan corrugated multilayer and couch board is fitted; Paste with continuous printing paper roll simultaneously and form the corrugated board that there is printed patterns on the top layer.After this corrugated board cuts off by specification, size, put into the corrugated board printing slotting machine and its otch fluting (because of top layer rolling printing, is not republished here by the carton specification; If there is not the rolling printing, corrugated board is at this machine printing top layer pattern).Corrugated board behind the otch fluting is the regulation carton at carton paste punch-out equipment or box press binding.
At present since the corrugated board thickness deviation to reach the coil paper surface too greatly too coarse, not bright and clean, lackluster, corrugated case color printing effect is relatively poor.Simultaneously, aspect the packings of product such as chilled food, marine product, fruits and vegetables, carton can only pass through the waxdip protection against the tide, causes the carton cost too high and be subjected to promoting restriction.At the corrugated case production status, domestic wrapping enterprise carries out application studies such as cast polypropylene film, polyester film, biaxially oriented polypropylene film one after another.
Existing film seal major technique is that pattern is printed in plastic foil (particularly biaxially oriented polypropylene film), though pattern be imprinted on film outer surface or in the surface, because the bright and clean and saturation degree of printing-ink adds film fineness and refraction action, undoubtedly can be more exquisite, rich merchant's product value more than printing on paper.But utilize existing cardboard box printing machine to print biaxially oriented polypropylene film one by one because film has strong electrostatic interaction, can't print at all and chromatography accurate; With existing plastic gravure machine or flexible flange printing machine rolling printing biaxially oriented polypropylene film, again it is utilized behind customized cut-off behind the dry compound machine coating adhesives such as OPP or CPP laminating machine with to cut off corrugated board compound by printed patterns and design, because of heating coated binding agent, film has necessarily and elongates or shortens, and has influence on that printed patterns repeats and different in size.With the film printed patterns is fixed length, because of film can produce different in size compound to irregular with the corrugated board that is cut to fixed length at heating coated binding agent.The serious electrostatic influence of film in addition, more difficultly when composition operation, align with cardboard, back cardboard otch fluting more can't accurately be located, 8 flangings of carton and 6 faces all can't be alignd with the design code printed patterns, each face printed patterns is interfered with each other.
Rolling is printed biaxially oriented polypropylene film utilize dry compound machine coating adhesives such as OPP or CPP laminating machine, compound with the corrugated board that cuts off simultaneously, also still can have influence on that printed patterns repeats and different in size because of causing film to have to film heating coated binding agent necessarily to elongate or shorten, so with the corrugated board that is cut to fixed length can't be accurately compound and cut film surely.If reduce heating-up temperature printed patterns is not is not elongated or shortened as possible, though thereby may ordinary production but reduce combined efficiency greatly and speed cost rising, uneconomical.
And the multiple paper seal of film technology is topped one by one on the top layer that cuts off printed patterns cardboard or carton by going after being coated with a layer binder on the film surface with coating method, or the topped top layer of film surface printing pattern at cardboard or carton, to reach more gloss, bright and clean and attractive in appearance of printed patterns, increase the purpose of carton intensity and humidity resistance simultaneously.But it is too coarse, not bright and clean, lackluster that the corrugated board thickness deviation reaches the coil paper surface too greatly, and the multiple paper printing corrugated paper box pattern of film can't reach design effect.
Therefore, existing market have only in advance be beautifully printed as possible on the corrugated board surface layer paper pattern and with the biaxial stretching film of layer of transparent or casting films through the coated binding agent after the color printing packing case compound with cardboard surface layer paper, and can't obtain after biaxially oriented polypropylene film is beautifully printed pattern compound and make packing case with packing case surface layer paper.
