The first breaking line 6 and the second breaking line 7 are cut through the bottom layer (5) from the bottom layer 5 to the lower surface of the surface layer 2, but not cut through the surface layer (2), the bottom layer (5), the bonding layer 4 and the anti-sticking layer 3 are divided into an A part, a B part and a C part, the C part between the second breaking line 7 and the sealing mark is an opening part, the anti-sticking layer 3 is positioned between the surface layer (2) and the bonding layer (4), and preferably, the anti-sticking layer 3 is only positioned between the B part and the bonding layer 4 in the bottom layer (5), as shown in fig. 2;
The first fracture line (6) is a straight line; the second breaking line (7) is a straight line or a wavy line, preferably, the second breaking line (7) is formed by interconnecting a groove 701 and a protrusion 702, as shown in fig. 5;
The dimension of the sealing label surface layer (2) is consistent with that of the bottom layer (5), and the dimension of the sealing label surface layer is consistent with that of the prior traditional sealing label, so that the prior equipment and process are used for producing cigarette packages;
The surface image-text information layer (1) can be printed image text, holographic image text, directional regression reflection information, three-dimensional image-text information or other anti-counterfeiting technical information; the surface graphic information layer (1) is provided with an opening position indication, so that a consumer can conveniently open the seal mark from one end of the seal mark C part according to the indication;
The surface layer (2) and the bottom layer (5) can be made of a polyester film, paper, synthetic paper or paper-plastic composite material, and the polyester material can be PET (polyethylene terephthalate), BOPP (biaxially oriented polypropylene), OPP (oriented polypropylene), PP (polypropylene), PVC (polyvinyl chloride), PE (polyethylene) or PC (polycarbonate) and the like; the thickness of the surface layer (2) and the bottom layer (5) is 1-100 micrometers;
The anti-sticking layer (3) can be made of anti-sticking materials such as water-based gloss oil, solvent-based gloss oil, UV gloss oil, organic silicon release coating, fluorine release coating, wax release coating, UV release coating and the like, and can be prepared by means of coating, printing and the like; the thickness of the release layer is 1 to 20 microns;
The bonding layer (4) is a pressure sensitive adhesive and can be rubber pressure sensitive adhesive, acrylic pressure sensitive adhesive, polyurethane pressure sensitive adhesive and the like; the thickness of the adhesive layer (4) is 3 to 50 micrometers;
after the seal label is attached to the cigarette package, the first breaking line (6) is positioned at the opening of the inner liner of the cigarette;
As shown in fig. 6 to 8, the seal label of the present invention is applied to the seal of a cigarette packet, when the seal label of the present invention is used, the seal label can be adhered to the cigarette packet after coating the adhesive on the a and B parts on the other side of the label bottom layer (5) by the prior art, wherein the C part of the seal label bottom layer (5) is not coated with the corresponding adhesive; meanwhile, the adhesive force between the adhesive layer (4) and the anti-adhesion layer (3) is smaller than the adhesive force between the bottom layer (5) and the surface of the cigarette package, so that when the seal mark is uncovered, the A and B parts in the bottom layer still adhere to the surface of the cigarette package, the C part of the bottom layer and the surface layer are uncovered, and the preferential scheme is that when the seal mark is uncovered, the surface layer with the anti-adhesion layer part between the first fracture line (6) and the second fracture line (7) is separated from the bottom layer B, and the surface layer on the other side of the first fracture line (6) and the surface layer on the other side of the second fracture line (7) still adhere to the A and the C of the bottom layer, as shown in figure 7;
Because the existing cigarette packaging equipment and the existing sticking mode of the sealing label and the cigarette outer package are widely used, the sealing label is usually glued and is used for sticking on the cigarette outer package and the lining paper; the sealing label capable of being repeatedly opened and closed is adopted, a lifted part is required to be reserved for a consumer, the original gluing length is reduced, the adhesion between the sealing label and the cigarette outer package is affected, and particularly, the phenomena that the sealing label part is sprung and falls off and the like are easily caused in the rapid production process; the fracture line shape can keep the original gluing length to the greatest extent, and is convenient for the use of the existing production equipment;
After the seal label is adhered to the soft package cigarette package through the adhesive, a consumer can conveniently uncover the seal label from one end of the seal label C part according to the opening position indication on the surface information layer, and the consumer can easily uncover the surface layer and the bottom layer C part of the seal label because no adhesive is arranged between the bottom layer C part of the seal label and the cigarette package; meanwhile, as the surface layer and the bottom layer are provided with the bonding layer and the anti-sticking layer structure, and the bonding force between the surface layer and the bottom layer is smaller than the bonding force between the bottom layer and the cigarette package, the surface layer with the anti-sticking layer part is uncovered and separated from the bottom layer; when the sealing label is uncovered to the second fracture line (7) of the bottom layer, the surface layer is separated from the bottom layer B, the bottom layer B is partially left on the cigarette package, and when the sealing label is continuously uncovered to the first fracture line (6), the sealing label is uncovered together with the bottom layer and the lining paper as being positioned at the sealing part of the lining paper of the cigarette package, so that the purpose of unsealing the cigarette is achieved, and a consumer can take out the cigarette; because the uncovered part of the surface layer is provided with the pressure sensitive adhesive, a consumer can still close and seal the surface layer on the original bottom layer, and only the part with the anti-sticking layer is overlapped with the bottom layer with the pressure sensitive adhesive, thereby realizing the purpose of repeatedly opening and closing.
When opened, the sealed cigarette packet is shown in figure 8.
The invention also provides a preparation method for preparing the repeatedly openable and closable cigarette soft package sealing label, which is characterized by comprising the following steps of:
(1) Printing required graphic and text information or composite anti-counterfeiting information on one surface of the surface layer material which is made of paper, polyester film, synthetic paper or paper-plastic composite material, and printing corresponding opening position indication information and label die-cutting outer frames;
(2) Printing or coating an anti-sticking layer on the other side of the surface layer material, wherein the anti-sticking layer is printed on the part B and the bonding layer (4) in the bottom layer (5) in a preferable scheme;
(3) Paper, polyester film, synthetic paper or paper-plastic composite material is used as a bottom material, and one side of the bottom material is fully printed or coated with a pressing surface adhesive;
(4) Compounding the side of the bottom layer material with the pressure sensitive adhesive prepared in the step (3) with the side of the surface layer material with the anti-adhesive layer prepared in the step (2) by using compounding equipment,
(5) Using a positioning die cutting device to die-cut the bottom layer material in the composite material in the step (4) to form 2 fracture lines, and cutting the bottom layer material into A, B, C parts without cutting the surface layer material; the position of one fracture line depends on the sealing position of the lining paper of the soft package cigarette, and when the sealing is marked on the sealing of the cigarette package, the first fracture line is positioned at the sealing position of the lining paper of the cigarette;
(6) Using a positioning die-cutting device to die-cut the material prepared in the step (5) into a final sealing mark according to a label die-cutting frame printed on the surface of the material;
Because of the different soft packet cigarette packaging equipment, the sealing label prepared by the preparation method can also be used independently, and when in use, the sealing label is adhered to a cigarette sealing place after the soft packet cigarette packaging equipment is used for automatically coating an adhesive; the continuous sealing label can be manufactured without printing a cutting line on the surface of the label and the label die cutting procedure of the step (6) in the surface information, and the roll-shaped continuous sealing label can be formed by automatically coating an adhesive through soft package cigarette packaging equipment and sticking the adhesive at a cigarette sealing position after the seal is broken along the surface cutting line when the roll-shaped sealing label is used;
The sealing label with the multilayer structure has the use effect of repeatedly opening and closing the label, and the original soft package cigarette packaging process and equipment are not required to be changed, so that the process is greatly simplified, and the cost is reduced; meanwhile, the sealing label can be repeatedly opened only by controlling the bonding force between the bonding layer and the anti-sticking layer to be smaller than the bonding force between the bottom layer and the cigarette package, and can be used only by adjusting the bonding force between the bottom layer and the cigarette package for various tobacco packages, so that the using process difficulty of the sealing label is greatly reduced, and the application range is increased; in addition, compared with the prior common soft package cigarette sealing label, the sealing label can be used by consumers to achieve the function of repeatedly opening and closing the cigarette sealing, and solve the problem that the cigarettes are easy to become wet and smell after being opened.
In addition, the sealing label is of a multi-layer structure, but the appearance of the sealing label is consistent with that of the traditional sealing label, so that the sealing label is beneficial to the industrial production of the traditional cigarette packaging equipment.
