Example is only a part of embodiment of the present invention, rather than the embodiment of whole.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Fig. 1 show an example of the compound package material of the present invention.The form of compound package material 1 mostly is coiled material,
Including multiple units 2 for forming independent packaging, dot matrix 3,3 ', wherein dot matrix 3 and dot matrix 3 ' on each unit, are coated
It is different.In addition, the relative position description in the Rotating fields description of the compound package material being related in the present invention from top to bottom
Relative position when being used for product packaging corresponding to compound package material from outside to inside is described.
As needed, compound package material 1 can cut into sheet material according to each unit before dispatching from the factory.
Fig. 2 show the cross-sectional view of the compound package material of one embodiment of the invention.Compound package material 1 includes
Waterproof layer 11, printing layer 12 and basic unit 13, dot matrix 14 are imprinted in printing layer 12.Compound package material 1 can also include gas barrier layer
15 and sealant layer 16, gas barrier layer 15 and sealant layer 16 are set in turn in the lower section of basic unit 13.In basic unit 13 and gas barrier layer 15
Between the first tack coat 17 can also be set, the second tack coat 18 can also be set between gas barrier layer 15 and sealant layer 16.
When compound package material 1 shown in Fig. 3 is used for product packaging, Rotating fields from outside to inside are followed successively by:Dot matrix 14/ is prevented
11/ printing layer of water layer, 12/ 13/ first tack coat of basic unit, 17/ 15/ second tack coat of gas barrier layer, 18/ sealant layer 16.
When compound package material 1 shown in Fig. 4 is used for product packaging, Rotating fields from outside to inside are followed successively by:Dot matrix 14/ prints
12/ waterproof layer of brush layer, 11/ 13/ first tack coat of basic unit, 17/ 15/ second tack coat of gas barrier layer, 18/ sealant layer 16.
The Rotating fields of the compound package material 1 of the present invention are not limited to the structure shown in Fig. 2-Fig. 4, such as may also include:
12/ basic unit of waterproof layer 11/ dot matrix, 14/ printing layer, 13/ gas barrier layer, 15/ sealant layer 16;Or, 11/ dot matrix of waterproof layer
14/ printing layer, 12/ 17/ gas barrier layer of basic unit 13/ first tack coat, 15/ sealant layer 16;Or, 11/ dot matrix of waterproof layer, 14/ printing layer

In composite 1, waterproof layer 11 is thermoplastic resin, preferably polyolefin, including but not limited to low density polyethylene (LDPE)
(LDPE), metallocene PE (m-PE) or the mixture both which.Basic unit 13 is paper substrate.
Consider that printing layer 12 preferably uses water color ink from environmental angle and food security angle.
The production of the compound package material of liquid beverage packaging generally includes following big step:
Printing, impression, punching, compound, cutting etc..
In theory, the spraying of dot matrix can be carried out between composite steps or even after composite steps in print steps
Operation.
By taking the spraying for carrying out dot matrix in print steps as an example, the spraying of dot matrix recognizes composite packaging based on photoelectric sensor
Positioning on material is identified and is controlled.Dot matrix spray equipment generates system with dot matrix simultaneously and is connected, so that it is guaranteed that each dot matrix
It is different.
Drying unit is configured with after dot matrix spray equipment, to guarantee the printing quality of dot matrix.
For having finished printing, but not yet compound packaging material blank, it is also possible to mended by this method offline
Specking battle array.
According to another implementation of the invention, the spraying of dot matrix is controlled based on the operational data of printing equipment.
The operational data of printing equipment can both be that the control system of printing equipment is provided, or by individually counting
Gather according to harvester.
Operational data include but is not limited to into paper size, print repeat length, chromatography precision, maximum print width, colour cell,
With one or more in print speed printing speed.
The spraying of dot matrix can be carried out while other patterns are printed, it is also possible to single after other pattern printings are completed
Solely carry out.
The background color or pattern of printing layer be solid color or combined by least two colors, be superimposed and formed, pattern include but
It is not limited to figure, word, trade mark or its combination.
According to another implementation of the invention, dot matrix is using the coating print that can be recognized by naked eyes black light
System, naked eyes black light include near-infrared, far infrared or ultraviolet.
The coating that can be recognized by the near-infrared in naked eyes black light or far infrared is the visible coating of carbon containing or contains
The invisible coating of carbon, wherein, the visible coating of carbon containing is visible ink, ink powder or the ink of carbon containing;The invisible coating of carbon containing is
The invisible printing ink of carbon containing, ink powder or ink.Due to the visible ink or ink of carbon containing, and the colorless ink or ink energy of carbon containing
The infrared ray of specific band is absorbed enough, therefore, only infrared ray identifying device can be identified to the information in label layer.
Can by naked eyes black light in the ultraviolet coating for recognizing be fluorescent paint.
According to a preferred embodiment of the invention, dot matrix generate system according to company ERP system or production time,
The production process informations such as the place of production, production line are formulated dot matrix coding rule and generate corresponding dot matrix, and identification equipment is recognized to dot matrix
Afterwards, dot matrix is decoded as by corresponding production process information according to coding rule.
Production process information be numeral, word, letter in one or two kinds of combination of the above into character string.
According to a preferred embodiment of the invention, dot matrix is to carry out having for arrangement form is repeated several times by lattice module
The mark of designated shape, lattice module formulate coding rule according to process of producing product information, and generate system generation by dot matrix,
It is to be identified the minimum area unit that equipment identifies information, when in dot matrix, partial dot array module is blocked or destroys,
Identification equipment remains to draw information by the identification to remaining lattice module in dot matrix.
