Embodiment
Coordinate diagram and preferred embodiment of the present utility model below, it is predetermined real to reach that the utility model is expanded on further
The technological means taken with new purpose.
Fig. 1 show the stereogram of the compound package material of the embodiment of the utility model one.Compound package material 1 has many
The individual unit 2 for being used to form individual packaging.Each unit 2 is provided with tag component, and the tag component of unit two-by-two is different.
Tag component 3,3 ' for example shown in Fig. 1 is located in different units, and tag component 3 and tag component 3 ' are different.
In addition, the relative position description correspondence in the Rotating fields description for the compound package material 1 being related in the utility model from top to bottom
Relative position description when compound package material 1 is used for product packaging from outside to inside.
Fig. 2 show the cross-sectional view of the compound package material of the embodiment of the utility model one.It is described from inside to outside
Compound package material 1 includes basic unit 11, the first printing layer 12, tag component 13, separation layer 14, shielding layer 15 and waterproof layer 16.
Basic unit 11 uses paper substrates.The area of separation layer 14 and shielding layer 15 is not less than the area of tag component 13, shielding layer 15
Tag component 13 can be sheltered from completely, and separation layer 14 is not directly contacted with shielding layer 15 and tag component 13.
Fig. 3 show the cross-sectional view of the compound package material of another embodiment of the utility model.Fig. 3's and Fig. 2
Difference is, after the completion of the printing of shielding layer 15, the second printing is carried out above shielding layer, the second printing layer 17 is set, makes
The picture on surface of shielding layer 15 and overall printing pattern or color are more harmonious, having improved aesthetic appearance, or can print prompting consumer scrape
Open the prompting that shielding layer checks tag component.
Fig. 4 show the cross-sectional view of the compound package material of another embodiment of the utility model, and its difference is,
Shielding layer 14 only carries out partial occlusion to tag component 13, and separation layer 14 makes masking between tag component 13 and shielding layer 15
Layer 15 is not directly contacted with tag component 13.
Tag component 13 can be any of a horizontal and vertical parity check code, bar code, Quick Response Code, digit strings or therefrom optional one
It is combined more than kind, but is not limited to this.Tag component 13 is formed at the table of the first printing layer 12 by spraying, impressing or stickup
Face, the top of tag component 13 sets separation layer 14.
Separation layer 14 is transparent or translucent chemical solvent, the resin for being solidificated in the surface of tag component 13, in label
The surface of part 13 forms smooth, fine and close film layer, and the preferred UV gloss oil of separation layer 14 such as contains C=C insatiable hungers with acrylic resin
With the low-molecular-weight resin of double bond, acrylic monomers, acrylic acid epoxy, polyester, polyurethane etc. as prepolymer, with activity dilution
Agent, light trigger and other auxiliary agents composition;It can also be water-based gloss oil.
Separation layer 14 is located between tag component 13 and shielding layer 15, shielding layer 15 is not connect with tag component 13 directly
Touch;Further, since the adhesion of separation layer 14 and shielding layer 15 is less than the adhesion of waterproof layer 16 and shielding layer 15, and/or
The adhesion of person's separation layer 14 and shielding layer 15 is less than separation layer 14 and the adhesion of tag component 13 so that striking off shielding layer
During 15, waterproof layer 16 and shielding layer 15 come off from the surface of separation layer 14 in combination, and separation layer 14 still with label
Part 13 is combined together, and due to the protection of separation layer 14, will not be caused in abrading process tag component 13 breakage or
It is incomplete.
Shielding layer 15 is at least one layer of opaque ink printed above separation layer, the preferred scraped of opaque ink
Silver inks, can also be other opaque water-based inks, and water-based ink can be strengthened by repeatedly printing chalk and/or tusche
Screening effect, or change the color of shielding layer, printed such as on shielding layer 15 after one layer or two layers of white ink, republish one layer
Black ink.
Waterproof layer 16 is thermoplastic resin, preferably polyolefin, including but not limited to low density polyethylene (LDPE) (LDPE), cyclopentadienyl gold
Belong to polyethylene (m-PE) or the mixture both it.For the ease of striking off shielding layer 15, it is micro- that the thickness of waterproof layer 16 is not more than 20
Rice, preferably at 10-15 microns.In liquid food aseptic packaging field, waterproof layer 16 is arranged on tag component 13, separation layer
14th, on shielding layer 15, except shielding layer 15 can be prevented to be worn in transportation or be stripped off unintentionally, it can also make
Obtain tag component 13, separation layer 14, shielding layer 15 not contact with the external world, ensure the sterilizing of packaging material in liquid food process
Meet healthy requirement.
Compound package material may also include gas barrier layer and sealant layer, and gas barrier layer and sealant layer are set in turn in basic unit
Lower section.Gas barrier layer includes but is not limited to aluminium foil, ethylene-vinyl alcohol copolymer (EVOH), polyvinyl alcohol (PVOH), inorganic oxide
(such as SiO2) or polyamide.Sealant layer is thermoplastic resin, preferably comprises polyolefin, is included but is not limited to linear low
Density polyethylene (LLDPE), ultra-low density polyethylene, low density polyethylene (LDPE), metallocene PE or its mixture.
The utility model provides a kind of sheet material group, is isolated by above-mentioned packaging material by printing, spraying tag component, coating
Layer, coating shielding layer, import marking press impression, punching, and import composite production line complete waterproof layer etc. it is compound after, according to need
Will, cut into coiled material or sheet material group.
The utility model provides one kind and packed, by above-mentioned packaging material or sheet material group, by filling, sealing, whole
The liquid beverage of the steps such as shape formation is packed.
The utility model is particularly suitable for use in the packaging of liquid beverage, but the utility model not limited to this, the utility model
The product in terms of the product of other paper substrates packaging, such as food, medicine is also applied for simultaneously.
Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect
