Description

Technical Field

[0001] The present application relates to the technical field of cigarette packaging, and in particular to a cigarette packaging film and a cigarette packaging structure. Background Art

[0002] The cigarette packaging film for the outer packaging of cigarette packets or strip packs is generally a biaxially oriented polypropylene (BOPP) transparent film, which has good transparency, heat sealing, tear resistance and high degradability. In the continuous production process, a cigarette pull line with a certain tensile strength is first pasted horizontally along the roll packaging film. The pull line is usually located on the opening side of the conventional cigarette packet or strip pack, and then the packaging film is cut longitudinally to the required length with a rolling cutter. The pull line position on one side of the packaging film is a semicircular incision to form a pull head protruding from the side. There are short incisions parallel to the pull line on both sides of the pull head so that the packaging film can be torn along the pull line direction. A semicircular notch corresponding to the pull head is formed on the other side of the packaging film, and the cigarette packaging film is obtained after cutting according to the specified size. The cut packaging film is covered with the cigarette packet or strip pack, so that the side with the pull head covers the side with the notch, and a heat sealer is used to form a certain width of overlap. When in use, the packaging film on the opening side of the cigarette package can be unsealed by pulling the pull head and tearing the packaging film along the pull line, so that the cigarette or small pack of cigarettes can be taken out for use.

[0003] With the development of the mid- and high-end cigarette market, various gift box-style special-shaped cigarette packaging has appeared one after another. The opening directions of the packaging box and the packaging film are often inconsistent, and the packaging film needs to be completely removed before the cigarette packaging box can be opened to take out the cigarette. Because the packaging film has good tear resistance, when the packaging film is torn along the pull line direction, only part of the packaging film opening can be removed. Due to the requirements for packaging sealing, the cigarette packaging film and the cigarette outer packaging box are closely attached, and the remaining packaging film tear after removing the packaging film at one end is very flat, resulting in the problem that the packaging film cannot be completely removed by hand. Therefore, for special-shaped cigarette packaging, the existing cigarette packaging film structure is difficult to meet the demand for easy complete removal. In order to solve this problem, there is a technical solution in the prior art that multiple pull heads / multiple pull lines are set on the packaging film to achieve complete removal of the packaging film. The method of setting multiple pull heads / pull lines not only increases the complexity of the production process and the quality control cost, but also multiple pull heads affect the sealing and aesthetics of the product. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related art, the present application provides a cigarette packaging film and a cigarette packaging structure.

[0005] The present application provides a cigarette packaging film, comprising: a film substrate and a pull line, wherein the film substrate is provided with a tear head and a tear notch along both ends of the pull line; both ends of the tear head extend away from the pull line to form an oblique guide notch;

[0006] The membrane substrate is provided with a plurality of groups of invisible guide lines along the pull line;

[0007] Each set of invisible guide wires includes two invisible guide wires symmetrically arranged on both sides of the pull wire;

[0008] The angle between each invisible guide line and the pull line is an acute angle;

[0009] Each invisible guide line is composed of several laser recessed points.

[0010] Furthermore, the depth of the laser depression point is 1 / 3 to 3 / 5 of the thickness of the film substrate.

[0011] Furthermore, the angle between each invisible guide wire and the pull wire is 30° to 60°.

[0012] Furthermore, the angle between each invisible guide wire and the pull wire is 45°.

[0013] Furthermore, the length of each invisible guide wire is 1.5 to 2.5 cm.

[0014] Furthermore, the distance between adjacent groups of invisible guide lines is 1.5 to 2.0 cm.

[0015] Furthermore, the membrane substrate is provided with 4 to 6 groups of invisible guide lines along the pull line.

[0016] Furthermore, the angle between the oblique guide cutout and the pull wire is 30-60°.

[0017] Furthermore, the length of the oblique guide incision is 1.5 to 2.5 cm.

[0018] The present application also provides a cigarette packaging structure comprising: a cigarette box, and a cigarette packaging film coated on the surface of the cigarette box;

[0019] The cigarette packaging film is any one of the cigarette packaging films described above;

[0020] The end of the cigarette packaging film with the tear head covers the end with the tear notch, and a overlap with a preset width is formed by heat sealing.

[0021] The cigarette packaging film provided in the present application may have the following beneficial effects:

[0022] 1. The film substrate of the cigarette packaging film is provided with oblique guide cuts on both sides of the tear head, which are away from the pulling line direction. Compared with the method of providing parallel guide cuts on both sides of the pulling line, the oblique guide cuts can make the tearing direction extend to the outside of both sides of the pulling line, breaking the flat tear of the existing method, making it convenient to remove the entire packaging film by hand.

[0023] 2. The cigarette packaging film is provided with several groups of invisible guide lines along the pull lines on the film substrate. The angle between the invisible guide lines and the pull lines is an acute angle. Each invisible guide line is composed of several laser recessed points. When the crack reaches the first group of invisible guide lines, the film substrate is torn obliquely in two directions along the two invisible guide lines of the first group, and then as the guiding force disappears, the tearing direction shrinks toward the pull line position. When it reaches the position of the second group of invisible guide lines, the film substrate will be torn obliquely in two directions along the group of invisible guide lines. After repeated changes in the tearing direction for several times, wavy tears are formed on both sides of the pull lines of the film substrate, destroying the original smooth tear, so that the packaging film can be easily and completely removed by hand.

[0024] 3. To realize the oblique guide cut, it is only necessary to set the original parallel cuts on both sides of the packaging film pull head to oblique cuts with a preset angle, which requires little modification to the existing packaging film production equipment. To realize the invisible guide line, it is only necessary to add a laser point at the pull line position in the current packaging film production process, which is easy to operate and requires little modification to the existing packaging film production equipment.

[0025] In summary, after the cigarette packaging film provided by the present application is opened, the operator can easily remove the packaging film completely by hand; and the existing packaging film production equipment is only slightly modified, thereby reducing production costs.

In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0042] The embodiment of the present application provides a cigarette packaging film, which has a simple structure, is easy to process, and is easy to completely peel off from the packaging substrate. The technical solution of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0043] The present application embodiment provides a cigarette packaging film, see Figure 1 , which comprises: a membrane substrate 2 and a pull wire 3;

[0044] The film substrate 2 is provided with a tearing head 21 and a tearing notch 23 along both ends of the pull line 3; both ends of the tearing head 21 extend away from the pull line 3 to form an oblique guide notch 22;

[0045] The membrane substrate 2 is provided with a plurality of groups of invisible guide lines along the pull line 3;

[0046] Each group of invisible guide wires includes two invisible guide wires 24 symmetrically arranged on both sides of the pull wire 3;

[0047] The angle between each invisible guide wire 24 and the pull wire 3 is an acute angle;

[0048] Each invisible guide line 24 is composed of a number of laser recessed points.

[0049] The cigarette packaging film provided in this embodiment includes a film substrate 2 and a pull cord 3. The positional relationship between the film substrate 2 and the pull cord 3 can be the same as that in the prior art. Specifically, the pull cord 3 is arranged on the inner side of the film substrate 2 to assist in opening the package. The materials of the film substrate 2 and the pull cord 3 can also be the same as those in the prior art. Specifically, the film substrate 2 is made of BOPP film. The film substrate 2 is provided with a tearing head 21 and a tearing notch 23 at both ends of the pull cord 3. The tearing head 21 is used to facilitate consumers to grab and tear it off to open the package. The tearing head 21 and the tearing notch 23 can be semicircular.

[0050] The difference between this embodiment and the existing cigarette packaging film is that: on the one hand, the two ends of the tearing head 21 extend away from the pull line 3 to form an oblique guide cut 22; on the other hand, the film base 2 is provided with a plurality of groups of invisible guide lines along the pull line 3. Specifically:

[0051] Oblique guide cuts 22 are formed at both ends of the tear head 21 extending away from the pull line 3. Compared with the method of setting parallel guide cuts on both sides of the pull line 3, by setting the oblique guide cuts 22, the tearing direction can be extended to the outside of both sides of the pull line 3, breaking the flat tear of the existing method, making it convenient to remove all the packaging film by hand.

[0052] The oblique guide cut 22 can be set in a position of the initial opening so that the crack direction expands outward. When the crack reaches the end of the oblique guide cut 22, the film substrate 2 retracts toward the position of the pull line 3 due to the disappearance of the guiding force. To this end, the present application further sets a plurality of groups of invisible guide lines 24 along the pull line 3 on the film substrate 2. The angle between the invisible guide line 24 and the pull line 3 is an acute angle, and each invisible guide line 24 is composed of a plurality of laser depression points. When the crack reaches the first group of invisible guide lines, the film substrate 2 will tear obliquely in two directions along the two invisible guide lines 24 of the first group; then, as the guiding force disappears, the tearing direction retracts toward the position of the pull line 3. When it reaches the position of the second group of invisible guide lines 24, the film substrate 2 will tear obliquely in two directions along the two invisible guide lines 24 of the group. After several repeated changes in the tearing direction, a wavy tear is formed on both sides of the pull line 3 of the film substrate 2, so that the original flat tear is destroyed, so that the packaging film can be easily removed completely by hand.

[0053] For the above-mentioned oblique guide cut 22, it is only necessary to set the original parallel cuts on both sides of the packaging film pull head to oblique cuts with a preset angle, which requires little modification to the existing packaging film production equipment. The angle between the above-mentioned oblique guide cut 22 and the pull line 3 is preferably 30-60°, and the length of the oblique guide cut 22 is preferably 1.5-2.5 cm.

[0054] The above-mentioned invisible guide line 24 is composed of a number of laser depressions, that is, the above-mentioned invisible guide line 24 is set by laser dotting at the positions on both sides of the pull line 3. It is only necessary to add laser points at the pull line position in the current packaging film production process. It is easy to operate and implement, and the modification of the existing packaging film production equipment is also small. The depth of the laser depression is preferably 1 / 3 to 3 / 5 of the thickness of the film substrate 2. The angle between each invisible guide line 24 and the pull line 3 is preferably 30° to 60°, and most preferably 45°. The length of each invisible guide line 24 is preferably 1.5 to 2.5 cm. The distance between adjacent groups of invisible guide lines 24 is preferably 1.5 to 2.0 cm. The film substrate 2 is preferably provided with 4 to 6 groups of invisible guide lines 24 along the pull line 3.

[0055] From the above content, it can be seen that the cigarette packaging film provided by this application has the following advantages:

[0056] 1. The film substrate 2 of the cigarette packaging film is provided with oblique guide cuts 22 on both sides of the tear head 21, which are away from the direction of the pull line 3. Compared with the method of providing parallel guide cuts on both sides of the pull line 3, the oblique guide cuts 22 can be provided to extend the tearing direction to the outside of both sides of the pull line 3, breaking the flat tear of the existing method, making it convenient to remove the entire packaging film by hand.

[0057] 2. The cigarette packaging film is provided with several groups of invisible guide lines 24 along the pull line 3 on the film substrate 2. The angle between the invisible guide line 24 and the pull line 3 is an acute angle. Each invisible guide line 24 is composed of several laser depression points. When the tear reaches the first group of invisible guide lines, the film substrate 2 is torn obliquely in two directions along the two invisible guide lines of the first group, and then as the guiding force disappears, the tearing direction shrinks toward the position of the pull line 3. When it reaches the position of the second group of invisible guide lines, the film substrate 2 will be torn obliquely in two directions along the group of invisible guide lines. After repeated changes in the tearing direction for several times, wavy tears are formed on both sides of the pull line 3 of the film substrate 2, so that the original flat tear is destroyed, so that the packaging film can be easily and completely removed by hand.

[0058] 3. To realize the oblique guide cut, it is only necessary to set the original parallel cuts on both sides of the packaging film pull head to oblique cuts with a preset angle, which requires little modification to the existing packaging film production equipment. To realize the invisible guide line, it is only necessary to add a laser point at the pull line position in the current packaging film production process, which is easy to operate and requires little modification to the existing packaging film production equipment.

[0059] In summary, after the cigarette packaging film provided by the present application is opened, the operator can easily remove the packaging film completely by hand; and the existing packaging film production equipment is only slightly modified, which also reduces the production cost.

[0060] See also Figure 2 Another embodiment of the present application further provides a cigarette packaging structure, which includes: a cigarette box, and a cigarette packaging film 1 coated on the surface of the cigarette box; the cigarette packaging film is the cigarette packaging film 1 described in the above embodiment; the end of the cigarette packaging film 1 with a tear head 21 covers the end with a tear notch 23, and a overlap D with a preset width is formed by heat sealing.

[0061] The cigarette packaging structure provided in this embodiment has a cigarette packaging film 1 that adopts the structure of the above-mentioned embodiment, and the packaging method of the cigarette box can be the same as that of the prior art. The structure of the cigarette box can also be the same as that of the prior art, and it can specifically be a paper cigarette box, an aluminum cigarette box, a tinplate cigarette box, etc. The opening method of the cigarette box can be full opening, side opening, bottom opening, oblique opening, lifting, double-side opening, and code scanning opening. The structural form of the cigarette box can be a traditional rectangular cigarette box (such as Figure 2 As shown), it can also be a partitioned cigarette box or other special-shaped cigarette boxes, etc. As a preferred solution of this embodiment, the intersection point of the tearing head 21 and the oblique guide cut 22 is located in the middle of the overlap D.

[0062] The cigarette packaging structure provided in this embodiment includes the above-mentioned cigarette packaging film, which correspondingly also has the advantages of being easy for an operator to completely remove the packaging film barehanded and having low production cost, so it will not be described in detail here.
