Description

Reusable cigarette soft package sealing label and preparation method thereof

Technical Field

The invention relates to a cigarette soft package sealing label and a preparation method thereof.

Background technique

Traditional soft pack cigarettes all use sealing labels to seal the opening of the cigarette. When using, consumers need to tear off the sealing label, open the inner lining paper seal and take out the cigarette. Since the sealing labels currently used in the market are tightly bonded to the inner lining paper and outer packaging of soft pack cigarettes and are disposable, they will be torn off when consumers open the cigarettes, making it impossible to restore the original packaging function after the cigarettes are opened. In this way, the unused cigarettes are exposed to the air and are easily affected by moisture or environmental pollution, affecting the taste of the cigarettes, and even prone to deterioration and affecting the health of consumers.

At present, there are moisturizing sealing labels similar to those on small packages of napkins on the market, which can be repeatedly opened and closed to protect the products in the packaging. However, due to the wide variety of cigarette packaging, most of the packaging uses paper as the packaging material rather than plastic packaging of napkins. The properties of the ink, material, varnish and other materials used on the packaging surface are different. In order to achieve the repeated opening and closing function, it is necessary to match the adhesion to the surface properties of each packaging material. The process is very complicated and the cost is high. At the same time, the production and packaging equipment of existing cigarette manufacturers is very mature, and the production process route is stable. If the equipment and the original packaging process need to be changed, the cost is high and it is not conducive to promotion. This requires a new sealing label that has both the repeated opening and closing function and the same process as the existing cigarette sealing label.

Summary of the invention:

The purpose of the present invention is to provide a cigarette soft package sealing label which can be opened and closed repeatedly and a preparation method thereof, so as to overcome the defects existing in the prior art.

The cigarette soft pack sealing label of the present invention comprises, from the outside to the inside of the sealing label, a surface graphic information layer, a surface layer, an anti-sticking layer, an adhesive layer, a bottom layer, a first break line and a second break line;

The first break line and the second break line extend from the bottom layer to the lower surface of the surface layer, i.e., cut through the bottom layer but not the surface layer, and divide the bottom layer, the adhesive layer and the anti-adhesive layer into part A, part B and part C. The part C between the second break line and the sealing mark is the opening part, and the anti-adhesive layer is located between the surface layer and the adhesive layer;

After the sealing label of the present invention is adhered to the soft-pack cigarette package by an adhesive, the consumer can conveniently peel off the sealing label from one end of the sealing label C portion according to the opening position indication on the surface information layer. Since there is no adhesive between the bottom layer C portion of the sealing label and the cigarette package, the consumer can easily peel off the surface layer and the bottom layer C portion of the sealing label; at the same time, since there is an adhesive layer and an anti-adhesive layer structure between the surface layer and the bottom layer, and the adhesive force between them is smaller than the adhesive force between the bottom layer and the cigarette package, the surface layer with the anti-adhesive layer portion is peeled off and separated from the bottom layer. When the sealing label is peeled off to the fracture line of the bottom layer, the surface layer is separated from part B of the bottom layer, and part B of the bottom layer remains on the cigarette package. When the sealing label continues to be peeled off to the fracture line, since it is located at the seal of the inner lining paper of the cigarette package, it will be peeled off together with the bottom layer and the inner lining paper, thereby achieving the purpose of unpacking the cigarette, and the consumer can take out the cigarette. Since the peeled part of the surface layer has pressure-sensitive adhesive, the consumer can still close the surface layer of the sealing label to the original bottom layer, and only needs to overlap the original part with the anti-sticking layer with the bottom layer with the pressure-sensitive adhesive, thereby achieving the purpose of repeated opening and closing.

The present invention achieves the purpose of repeated opening and closing by adopting a sealing label with a multi-layer structure, and the sealing label itself has the effect of repeated opening and closing, and there is no need to change the original soft-pack cigarette packaging process and equipment, which greatly simplifies the process and reduces costs; at the same time, the sealing label of the present invention only needs to control the bonding force between the bonding layer and the anti-sticking layer to be less than the bonding force between the bottom layer and the cigarette packaging to achieve the purpose of repeated opening. For a wide variety of tobacco packaging, only the bonding force between the bottom layer and the cigarette packaging needs to be adjusted to use the sealing label of the present invention, which greatly reduces the process difficulty of using the sealing label and increases the scope of application; in addition, compared with the existing ordinary soft-pack cigarette sealing label, consumers can use the sealing label of the present invention to achieve the function of repeated opening and closing of the cigarette seal, solving the problem that the cigarette is easily affected by moisture and tastes bad after opening. In addition, although the sealing label of the present invention is a multi-layer structure, its appearance is consistent with the traditional sealing label, which is conducive to its industrial production on existing cigarette packaging equipment.

Detailed ways

As shown in Fig. 1 to Fig. 5, the cigarette soft pack sealing label of the present invention includes the following from the outside to the inside of the sealing label: a surface graphic information layer 1, a surface layer 2, an anti-sticking layer 3, an adhesive layer 4, a bottom layer 5, a first break line 6 and a second break line 7;

The first break line 6 and the second break line 7 extend from the bottom layer 5 to the lower surface of the surface layer 2, i.e., cut through the bottom layer (5) but do not cut through the surface layer (2), and divide the bottom layer (5), the adhesive layer 4 and the anti-adhesive layer 3 into part A, part B and part C. The part C between the second break line 7 and the sealing mark is the open part, and the anti-adhesive layer 3 is located between the surface layer (2) and the adhesive layer (4). Preferably, the anti-adhesive layer 3 is only located between part B of the bottom layer (5) and the adhesive layer 4, as shown in FIG2 ;

The first fracture line (6) is a straight line; the second fracture line (7) is a straight line or a wavy line. Preferably, the second fracture line (7) is composed of a groove 701 and a protrusion 702 connected to each other, as shown in FIG5 ;

The dimensions of the sealing label surface layer (2) and the bottom layer (5) are consistent with the external dimensions of existing traditional sealing labels, so that cigarette packaging can be produced using existing equipment and processes;

The surface graphic information layer (1) may be printed graphics, holographic graphics, directional retro-reflective information, three-dimensional graphics or other anti-counterfeiting technical information; the surface graphic information layer (1) has an opening position indicator, which is convenient for consumers to open the sealing label from one end of the sealing label C according to the indicator;

The materials of the surface layer (2) and the bottom layer (5) can be 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), etc.; the thickness of the surface layer (2) and the bottom layer (5) is 1 micron to 100 microns;

The anti-sticking layer (3) can be made of anti-sticking materials such as water-based varnish, solvent-based varnish, UV varnish, silicone release coating, fluorine-based release coating, wax release coating, UV release coating, etc., and can be prepared by coating, printing, etc.; the thickness of the anti-sticking layer is 1 micron to 20 microns;

The adhesive layer (4) is a pressure-sensitive adhesive, which may be a rubber-based pressure-sensitive adhesive, an acrylic pressure-sensitive adhesive, a polyurethane pressure-sensitive adhesive, etc.; the thickness of the adhesive layer (4) is 3 microns to 50 microns;

After the sealing label is pasted on the cigarette package, the first break line (6) is located at the opening of the cigarette lining;

As shown in Figures 6 to 8, it is a schematic diagram of the sealing label of the present invention being applied to the sealing of cigarette packages. When the sealing label of the present invention is used, the existing technology can be used to apply adhesive to the A and B parts on the other side of the label bottom layer (5) and then adhere to the cigarette package, wherein the C part of the bottom layer (5) of the sealing label is not coated with the corresponding adhesive; at the same time, the bonding force between the adhesive layer (4) and the anti-adhesive layer (3) is smaller than the bonding force between the bottom layer (5) and the surface of the cigarette package, so as to ensure that the A and B parts of the bottom layer are still adhered to the surface of the cigarette package when the sealing label is peeled off, and the C part of the bottom layer and the surface layer are peeled off. The preferred solution is that when the sealing label is peeled off, the surface layer with the anti-adhesive layer part located between the first fracture line (6) and the second fracture line (7) is separated from the bottom layer B, while 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) are still bonded to the bottom layers A and C, as shown in Figure 7;

Since the existing cigarette packaging equipment and the existing sealing label and cigarette outer packaging pasting method have been widely used, the sealing label is mostly pasted on the cigarette outer packaging and the inner lining paper by gluing; the sealing label that can be opened and closed repeatedly needs to reserve a part for consumers to use, which will inevitably reduce the length of the original gluing and affect the adhesion between the sealing label and the cigarette outer packaging, especially in the fast production process, it is easy to cause the sealing label to partially bounce off or fall off; the above-mentioned fracture line shape of the present invention can retain the original gluing length to the maximum extent, which is convenient for the use of the existing production equipment;

After the sealing label of the present invention is adhered to the soft-pack cigarette package by an adhesive, the consumer can conveniently peel off the sealing label from one end of the sealing label C portion according to the opening position indication on the surface information layer. Since there is no adhesive between the bottom layer C portion of the sealing label and the cigarette package, the consumer can easily peel off the surface layer and the bottom layer C portion of the sealing label; at the same time, since there is an adhesive layer and an anti-adhesive layer structure between the surface layer and the bottom layer, and the adhesive force between them is smaller than the adhesive force between the bottom layer and the cigarette package, the surface layer with the anti-adhesive layer portion is peeled off and separated from the bottom layer; when the sealing label is When the cover is peeled off to the second fracture line (7) of the bottom layer, the surface layer is separated from the bottom layer B, and the bottom layer B remains on the cigarette package. When the sealing label is peeled off to the first fracture line (6), since it is located at the sealing portion of the inner lining paper of the cigarette package, it will be peeled off together with the bottom layer and the inner lining paper, thereby achieving the purpose of unpacking the cigarettes, and the consumer can take out the cigarettes. Since the peeled portion of the surface layer has pressure-sensitive adhesive, the consumer can still close the sealing label surface layer to the original bottom layer, and only needs to overlap the original part with the anti-sticking layer with the bottom layer with the pressure-sensitive adhesive, thereby achieving the purpose of repeated opening and closing.

When opened, the sealed and labeled cigarette pack is packaged as shown in FIG8 .

The present invention also proposes a method for preparing the above-mentioned cigarette soft package sealing label that can be opened and closed repeatedly, which is characterized by comprising the following steps:

(1) Using paper, polyester film, synthetic paper or paper-plastic composite material as the surface material, printing the required graphic information or composite anti-counterfeiting information on one side, and printing the corresponding opening position indication information and label die-cutting frame;

(2) printing or coating a release layer on the other side of the surface material. A preferred solution is to print the release layer on the B portion of the bottom layer (5) and the adhesive layer (4);

(3) Using paper, polyester film, synthetic paper or paper-plastic composite material as the base material, with full printing or coating of a pressing adhesive on one side;

(4) using a laminating device to laminate the side of the bottom layer material prepared in (3) with the pressure-sensitive adhesive and the side of the surface layer material prepared in (2) with the anti-adhesive layer,

(5) Using a positioning die-cutting device to die-cut the bottom layer material of the composite material in the above (4) to form two fracture lines, cutting the bottom layer material into three parts A, B, and C, but not cutting the surface layer material; the position of one of the fracture lines depends on the sealing position of the lining paper of the soft pack cigarette, and when the sealing label is affixed to the cigarette packaging seal, the first fracture line should be at the cigarette lining paper seal;

(6) using a positioning die-cutting device to die-cut the material prepared in (5) into a final sealing label according to the label die-cutting frame printed on its surface;

Due to the difference in soft-pack cigarette packaging equipment, the sealing label prepared according to the preparation method of the present invention can also be used alone. When in use, the soft-pack cigarette packaging equipment automatically applies adhesive and then sticks it to the cigarette sealing part. It can also be made into a continuous sealing label, which does not need to print a die-cutting frame in the surface information, but only needs to print a cutting line on the label surface. At the same time, it does not need to perform the label die-cutting process of the above step (6), and a roll-shaped continuous sealing label can be formed. When using the roll-shaped sealing label, the soft-pack cigarette packaging equipment automatically applies adhesive and cuts the label along the surface cutting line and then sticks it to the cigarette sealing part.

The present invention achieves the effect of repeatedly opening and closing the label itself by adopting a sealing label with a multi-layer structure, and there is no need to change the original soft-pack cigarette packaging process and equipment, which greatly simplifies the process and reduces the cost; at the same time, the sealing label of the present invention only needs to control the bonding force between the bonding layer and the anti-sticking layer to be less than the bonding force between the bottom layer and the cigarette package to achieve the purpose of repeated opening, and for various types of tobacco packaging, only the bonding force between the bottom layer and the cigarette package needs to be adjusted to use the sealing label of the present invention, which greatly reduces the process difficulty of using the sealing label and increases the application scope; in addition, compared with the existing ordinary soft-pack cigarette sealing label, consumers can use the sealing label of the present invention to achieve the function of repeatedly opening and closing the cigarette seal, which solves the problem that the cigarette is easily affected by moisture and changes in taste after opening.

In addition, although the sealing label of the present invention is a multi-layer structure, its appearance is consistent with that of a traditional sealing label, which is conducive to its industrial production on existing cigarette packaging equipment.
