Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, an anti-counterfeiting laser moisturizing and moisture preserving composite packaging material comprises a protective layer 1, an anti-counterfeiting laser layer 2, a base layer 3, an adhesive layer 4, an aluminum foil layer 5 and an OPP layer 6, wherein the protective layer 1 is 2um-5um, the anti-counterfeiting laser layer 2 is 21um-25um, the adhesive layer 42um-4um, the base layer 3293um-297um, the aluminum foil layer 54um-8um and the OPP layer 618um-22um, and the materials are combined together through a laser anti-counterfeiting composite process, an aluminum foil OPP laminating process and the like, so that the composite packaging material is obtained. The protective layer mainly plays the effect that the protection radium-shine anti-fake effect was played and is fit for the printing, and radium-shine layer of preventing falsification mainly plays anti-fake effect and positive moisturizing, and the tie coat mainly combines radium-shine anti-fake layer and basic unit together, and the basic unit is this packaging material's skeleton, and aluminium foil layer, OPP layer mainly play the dampproofing effect of moisturizing in the aspect. The material is realized as follows:
the first step is as follows: original paper (base layer)) is processed, and the laser anti-counterfeiting effect is transferred to the front side of the paper. The process mainly adopts a wet compounding technology, uses wet compounding machine equipment to transfer roll paper and a winding drum to a film, and transfers the laser effect to the front side of the paper through a three-roller gluing and laminating technology. In the process, the moisture of the paper (base layer) and the tension of the anti-counterfeiting laser layer are very important to control, the moisture of the paper (base layer) is too large, the stiffness of the material is not enough, the moisture of the paper (base layer) is too small, and the whole material is hard and cannot be normally used. In this process, the control of temperature and speed is also particularly critical, and only by perfectly matching the two, it is possible to obtain a semi-finished material with moderate flexibility and suitable for subsequent processing.
And secondly, processing the back of the laser transfer paper with the front surface subjected to the laser transfer processing. Firstly, an aluminum foil is attached to the back of paper, then the paper passes through three stations of one process, then film spraying is carried out on the surface of the aluminum foil, and finally after the film spraying is finished, the roll paper is wound after being balanced by a low-temperature oven. In the process, the precision requirement of the laminating station of the aluminum foil is highest, because the purity of the aluminum foil reaches 99.99 percent, the thickness is about 6 microns, and the tension control is extremely achieved. Too high tension, broken aluminum foil, too low tension, wrinkling and unevenness. Simultaneously, before the aluminum foil is attached, glue is coated on the attaching surface of the aluminum foil once through two rollers, the thickness of the glue is about 3 microns, and the thickness of the glue also influences the attaching smoothness and fastness of the aluminum foil. After the laminating, the film is laminated on the back of the paper through the balance of three stations, the film used for laminating is an OPP film, the back of the paper is laminated through a film laminating process, the tension control requirement of the film is very high during film laminating, the film cannot be distorted or wrinkled, and the like, otherwise, the problem of distortion or warpage can occur after the paper is broken, and the film cannot be used.
And thirdly, processing the surface of the paper again. And coating a protective layer coating which is scratch-resistant, improves the surface brightness of the paper and enhances the printing adaptability on the front surface of the paper, then drying, rolling and finally cutting into the specification required by a customer.
In the technology, the glue on the binding surface of the aluminum foil is the bonding layer.
The wet compounding technology mentioned in the technology is to coat a layer of water-soluble adhesive on the surface of a composite base material (plastic film, aluminum foil), compound the adhesive with other materials (paper, cellophane) through a press roll under the condition that the adhesive is not dry, and dry the adhesive through a hot baking path to form a composite film layer. The wet compounding method has the characteristics of simple process operation, small using amount of the adhesive, low cost, quick compounding, generally 150-300 m/min and no residual solvent. The adhesive used in the wet compounding method mainly comprises casein resin-butyronitrile latex, polyvinyl alcohol, sodium silicate, starch, polyvinyl acetate, ethylene-vinyl acetate copolymer, polyacrylate, natural resin and the like.
The three-roller gluing and laminating technology is a coating and laminating technology, and mainly comprises a rubber-carrying anilox roller (steel roller), a spreading rubber roller (rubber roller), a gluing roller (press film) and a glue reducing roller for controlling the amount of glue. The relative positions of the rollers are the front upper position of the rubber reducing roller, the rubber-carrying anilox roller is arranged at the back lower position, the spreading rubber roller is arranged right above the rubber-carrying roller, and the gluing roller is arranged right above the spreading rubber roller. In the specific gluing process, about one third of the gluing roller is soaked in the gluing groove, the motor drives the gluing roller to rotate, and glue is brought up during rotation. In the rotating process, the spreading roller falls down through air pressure and is tightly attached to the rubber carrying roller, so that the rubber carrying amount of the rubber carrying roller is reduced and uniform, the rubber carrying amount of the rubber carrying roller is adjusted by adjusting the pressure of the spreading roller and the pressure of the rubber reducing roller, and the rubber carrying amount on the spreading roller is controlled at the same time. In the production process, the laser film passes through the film pressing roller, the film pressing roller is pressed on the gluing roller through air pressure, and the glue on the spreading roller can be coated on the laser film. The paper passes through the unwinding device on the other side and the laser film after being glued to simultaneously pass through the laminating device, and the fastness and the flatness of the lamination are adjusted by adjusting the pressure during lamination.
The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by a person skilled in the art that the scope of the invention as referred to in the present application is not limited to the embodiments with a specific combination of the above-mentioned features, but also covers other embodiments with any combination of the above-mentioned features or their equivalents without departing from the inventive concept. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
