Abstract
The present invention relates to a kind of in-mold labels, then got and punched on a series of hole on the label cut by machinery or laser, because the material after punching extrudes effect, boss will be formed around the hole at the back side of label film；When avoiding using automated machine crawl, the phenomenon of overlapping tags and/or the label that comes off is formed due to the bonding between label；Simultaneously as perforate and boss on label film, it is to avoid label film and plastic packaging containers produce bubble during laminating.
Description
Technical field
The present invention relates to a kind of label, and in particular to a kind of in-mold labels.
Background technology
At present, tag adhering in mould is widely used, and usually used relative to the past is plastics with polymeric labels
The method of label containers, it is not necessary to coat adhesive in label facestock sheet, it is not required that being set under adhesive to shell
From paste carrier.
Tag adhering in mould method of the prior art is side's absorption label film by negative pressure of vacuum or Electrostatic Absorption, and is led to
Cross manipulator in-mold labels are automatically fed into plastic packaging containers die cavity, be attached to the outer wall of corresponding plastic packaging containers,
Label is pasted onto to the surface of plastic packaging containers by heat fused, traditional artificial general is instead of using robotic automatic coating
Label is pasted on the mode of plastic packaging containers outer wall one by one.
But use above-mentioned tag adhering in mould method usually require by one pile label stack place, stack when by
Extruded in gravity and by the air between film label, simultaneously because between the effect of Electrostatic Absorption, the smooth label of surfacing
It is easy bond, cause label to be bonded together, when being captured using automated machine, it is difficult to ensure that every time only crawl one
Label, easily forms overlapping tags and/or the label that comes off.Further, since label and the plastic packaging containers shape during laminating
Into closed chamber, it is possible to produce bubble during laminating, causes waste product or needs subsequently to pierce through the PROCESS FOR TREATMENT of bubble.
The content of the invention
The invention aims to solve it is of the prior art stacked because label is in heaps, between the label being placed adjacent
It is also easy to produce electrostatic, absorption affinity big, easily adsorbs multiple labels when capturing label, cause the folded Zhang Wenti of labelling, solve simultaneously
Determine and the phenomenon of bubble is easily produced after label application in the prior art.
To achieve the above object, technical scheme is as follows：In a side surface coated heat melt material of base layer
Form hot melt layer；In another side surface application to printed material formation printing layer of base layer；By the label needed for in-mold label film
Size and shape is cut；Punched on the in-mold labels cut, boss is formed around the hole on the surface of label film.
In order to further realize the present invention, base layer includes one kind at least polymeric material, metal material, base layer
Thickness is 50~100 μm.
In order to further realize the present invention, described matrix layer is BOPET film, BOPP film, PE films, polypropylene are thin
One kind in film, polyethylene film, poly- third poly- second coextruded film, polystyrene film, built up membrane；Institute's hot sealing layer is after heating
The material easily melted is constituted.
In order to further realize the present invention, the boss is located at the surface of the hot sealing layer.
In order to further realize the present invention, the hole can be through hole or non-through hole.
In order to further realize the present invention, the hole is formed by mechanical punching or laser boring.
In order to further realize the present invention, a diameter of 0.01-1mm in the hole, preferably 0.1-0.5mm.
In order to further realize the present invention, the superficial layer is printing layer.
In order to further realize the present invention, the Kong Zhen of the hole formation rule arrangement.
In order to further realize the present invention, the Kong Zhen of the hole formation rule arrangement.
In order to further realize the present invention, the material that the hot sealing layer easily melts after heating is constituted.
Beneficial effect
One of the object of the invention is by machinery or laser boring, it is to avoid label film and plastic packaging containers were being fitted
Bubble is produced in journey；Boss can be formed in a side surface (being usually thermoplastic layer) for label film punch simultaneously after, so that
There is gap between label film, it is to avoid the bonding between label, when being captured using automated machine, overlapping tags will not be formed
And/or the phenomenon for the label that comes off.
Brief description of the drawings
Fig. 1 is the structural representation of label of the prior art；
Fig. 2 is the structural representation of the label film of the present invention.
Description of reference numerals：
1st, base layer；2nd, hot melt layer；3rd, printing layer；4th, hole；5th, boss.
Embodiment
A kind of embodiment of the present invention is described below：First selection base layer material (such as BOPET film,
BOPP film, PE films, polypropylene film, polyethylene film, poly- third poly- second coextruded film, polystyrene film, built up membrane
In), in a side surface coated heat melt material (such as EVA) the formation hot melt layer of base layer；Applied in another side surface of base layer
The printing layer of duplication brush material formation；Tag size and shape needed for in-mold label film is cut, can according to trade mark,
Cut the need for pattern and decoration；Then a series of hole is got on the label cut by machinery or laser, by
Effect is extruded in the material after punching, boss will be formed around the hole at the back side of label film.
The thickness of base layer is 50~100 μm, a diameter of 0.01-1mm in hole, preferably 0.1-0.5mm, formation rule or non-
Regularly arranged Kong Zhen；Label film after punching is placed in label box in a pile.
Label is captured by manipulator, generally using side's absorption label of negative pressure of vacuum or Electrostatic Absorption, and along machinery
Pushing ahead for the tracks of hand, in-mold labels are automatically fed into plastic packaging containers die cavity, are attached to corresponding plastics
The outer wall of packing container.
Heating of plastic packing container, (can be typically due to plastic packaging containers by the waste-heat of plastic packaging containers
Just blow molding, still remains with certain heat temperature when being blow molded out) so that the heat-fusible materials fusing of hot melt layer and with modeling
Material packing container is bonded to one.
Because hot melt layer melts after heating, it is integrated with plastic packaging containers fusion, the boss of hot melt layer disappears after fusion is closed
Lose, while hot melt layer material can be in access aperture by the closing of pores after heating, the label surface flat smooth after final assembly,
The attractive in appearance of surface is not interfered with.
The better embodiment of the present invention is the foregoing is only, the invention is not limited in above-mentioned embodiment, is being implemented
During there may be local small structural modification, if the various changes or modification to the present invention do not depart from the essence of the present invention
God and scope, and belong within the scope of the claim and equivalent technologies of the present invention, then the present invention is also intended to comprising these changes
And modification.
