Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, the in-mold label structure of the embodiment of the present invention comprises the separation unit 2 that can open again that label body 1 and label body 1 are provided with after described in-mold labels adheres to by the blowing technology compression molding, Yi Bian described separation unit 2 has at least on an edge of the label body of being arranged on.
Label body 1 is made by layer laminates, specifically comprise basic unit, printed layers and be compressed on basic unit and printed layers on functional layer, functional layer can be single or whole according to the real needs of reality be compressed on basic unit or printed layers, functional layer specifically comprises antistatic layer, anti oxidation layer, grease proofing pollution layer etc., in concrete enforcement, the concrete number of plies of label body 1 and the collocation relation of each layer do not limit, can be single basic unit, can be also the compound of basic unit and several functions layer.
In conjunction with referring to Fig. 2, Fig. 3 and shown in Figure 4, separation unit 2 has and is easy to otch 22 that separation unit 2 is opened again, and otch 22 is two, roughly is acute angle-shaped, adjacent is arranged on the end edge that separation unit 2 and label body 1 are joined.
The first adhesion coating 24 and the second adhesion coating 26 are suppressed respectively in the zone of separation unit 2, the first adhesion coating 24 is compressed on separation unit 2 and offers on the end regions surface of described otch 22, and the first adhesion coating 24 compression molding adhesion strengths are less than or equal to described the second adhesion coating 26 compression molding adhesion strengths; The compression molding adhesion strength of the adhesion coating 12 that the second adhesion coating 26 compression molding adhesion strengths have less than described label body 1.
Preferably, the temperature of separation unit 2 by the blowing technology compression molding time is 170 to 210 degree.The first adhesion coating 24 on separation unit 2 and the second adhesion coating 26 are spent the most easily fusion adhesion in the interval 170 to 210, and with this understanding, the first adhesion coating 24 compression molding adhesion strengths are less than or equal to described the second adhesion coating 26 compression molding adhesion strengths.
Preferably, easy-torn line is cut channel or the dark cut channel that is interrupted, and described dark cut channel refers to not penetrate half cut channel of label surface.。
the in-mold label structure of the embodiment of the present invention carries out compression molding and sticks to manufactured goods when surface, the adhesion coating that has the adhesion strength of the adhesion coating 12 that adhesion strength has less than label body 1 due to separation unit 2, simultaneously, the adhesion strength of the first adhesion coating 24 that the end regions of separation unit 2 close otch 22 has is less than or equal to the compression molding adhesion strength of the second adhesion coating 26, therefore, separation unit 2 near the end regions of otch 22 as Fig. 1, under the effect of directed force F to the right shown in Figure 2, be easy to form one among a small circle open the zone, under the continuous action of acting force, separation unit 2 continues to open along easy-torn line, until separation unit 2 is all separated with the manufactured goods surfaces.
What deserves to be explained is, separation unit 2 also can be arranged to identical with the compression molding adhesion strength of the second adhesion coating 26 near the compression molding adhesion strength of the first adhesion coating 24 of the end regions compacting of otch 22, as long as the adhesion strength of the adhesion coating 12 that the compression molding adhesion strength that satisfies separation unit 2 has less than label body 1, certainly, the first adhesion coating 24 also can not arrange adhesion strength, only be attached to after its mold pressing manufactured goods the surface but and adhesion.
In other embodiments of the in-mold label structure of the embodiment of the present invention, the position that separation unit is offered does not limit, separation unit also is arranged on the edge of described label body, wherein, separation unit can have one side to be arranged on an edge of label body, also can have two limits, three limits to be arranged on the edge of label body, other limits of separation unit and easy-torn line (being cut channel or dark cut channel) surround an obturator.In addition, separation unit also can be opened in the optional position of the label body such as end, middle part and lateral body of label body, has the zone that can open again as long as satisfy label body after described in-mold labels compression molding adheres to; The end edge that separation unit and label body are joined also can not arrange otch and easy-torn line, does not affect the enforcement of in-mold label structure; Certainly, the position that easy-torn line is offered and length neither be changeless, can adjust according to the demand of reality, for example, can two cross label, also can separation unit 2 be impaled by three and edge notches.
The embodiment of the invention also discloses a kind of manufacture method of in-mold labels, comprising:
Layer laminates is made label body;
Form the separation unit that to open again on the edge of described label body after described in-mold labels adheres to by the blowing technology compression molding, Yi Bian described separation unit has at least on an edge of the label body of being arranged on;
Compacting is by the adhesion coating of blowing technology compression molding adhesion strength less than described label body compression molding adhesion strength on described separation unit.
Layer laminates is made in the step of label body, and the concrete number of plies of label body and the collocation relation of each layer do not limit, and can be single basic units, can be also the compound of basic unit and several functions layer.
In the step that forms the separation unit that to open again on the edge of described label body after described in-mold labels adheres to by the blowing technology compression molding, the position of separation unit setting does not limit, separation unit also can be arranged on the edge of described label body, wherein, separation unit can have one side to be arranged on an edge of label body, also can have two limits, three limits to be arranged on the edge of label body, other limits of separation unit and easy-torn line (being cut channel or dark cut channel) surround an obturator; Separation unit also can be opened in the optional position of the label body such as end, middle part and lateral body of label body, has the zone that can open again as long as satisfy label body after described in-mold labels compression molding adheres to.
Compacting is by in the step of blowing technology compression molding adhesion strength less than the adhesion coating of described label body compression molding adhesion strength on described separation unit, the compression molding adhesion strength of the adhesion coating of suppressing on separation unit also can be set to difference, as long as satisfy the compression molding adhesion strength of separation unit less than the adhesion strength of label body.
Implement in-mold label structure and the manufacture method thereof of the embodiment of the present invention, be provided with the separation unit that to open again after described in-mold labels adheres to by the blowing technology compression molding due to label body, has again the adhesion coating of the adhesion strength of the adhesion coating that adhesion strength has less than label body due to separation unit, the separation unit of label body be easy to form one among a small circle open the zone, even in-mold labels also can be separated label and manufactured goods after compression molding.
Above disclosed is only a kind of preferred embodiment of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to claim of the present invention still belongs to the scope that the present invention is contained.
