Abstract
Description
Technical Field
[0001] This disclosure relates to the field of packaging technology, and in particular to a shrink label and packaging container. Background Technology
[0002] Shrink labels are used in the packaging technology field due to their excellent shrinkability. For example, shrink labels can be used to wrap the container itself, such as a bottle, serving both to display information and protect the container. Shrink labels can not only wrap regularly shaped containers, but also fit and wrap irregularly shaped parts of some containers after shrinking.
[0003] In related technologies, one type of shrink label has a glossy surface on the shrink film layer without special industrial treatment, while another type has a varnish containing particulate matter printed on the surface of the shrink film layer, giving the shrink label a gritty feel. Both types of shrink labels have a relatively hard feel. Utility Model Content
[0004] The purpose of this disclosure is to provide a shrink label and packaging container that addresses the problem of shrink labels in related technologies having a stiff feel.
[0005] The first aspect of this disclosure provides a shrink label, including:
[0006] Shrink film layer;
[0007] A light varnish layer with a soft touch is disposed on the surface of the shrink film layer; and
[0008] The graphic information layer is located in the inner layer of the shrink film layer.
[0009] In some embodiments of the shrink label, the varnish layer is a microbead coating composed of microbeads with a soft touch.
[0010] In some embodiments of the shrink label, the microbead coating is an aqueous acrylic microbead coating.
[0011] In some embodiments of the shrink label, the dry basis dosage of the water-based acrylic microbead coating is 1.5-3.5 g / m². 2 .
[0012] In some embodiments of the shrink label, the microbeads have the same particle size.
[0013] In some embodiments of the shrink label, the microbeads have a particle size range of 4-7 μm.
[0014] In some embodiments of the shrink label, the shrink film layer is a PETG shrink film layer or an OPS shrink film layer.
[0015] In some embodiments of the shrink label, the graphic information layer is a printed layer.
[0016] A second aspect of this disclosure provides a packaging container, comprising:
[0017] container body; and
[0018] The shrink label described in the first aspect of this disclosure is configured to be disposed on the exterior of the container body.
[0019] Based on the shrink label provided in this disclosure, by providing a varnish layer with a soft touch on the surface of the shrink film, the surface hardness of the shrink label is reduced, thus improving its feel. Furthermore, placing the graphic information layer in the inner layer of the shrink film helps maintain the clarity and durability of the graphic information.
[0020] The packaging container disclosed herein includes the shrink label of this disclosure, thereby having the advantages of the shrink label of this disclosure.

[0026] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0028] In the description of this disclosure, it should be understood that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this disclosure.
[0029] In the description of this disclosure, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are generally based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0030] like Figure 1 As shown, this embodiment of the disclosure provides a shrink label. The shrink label includes a shrink film layer 3, a varnish layer 1 with a soft touch, and a graphic information layer 2. The varnish layer 1 is disposed on the surface of the shrink film layer 3. The graphic information layer 2 is disposed on the inner layer of the shrink film layer 3.
[0031] Based on the shrink label provided in this embodiment, by providing a varnish layer 1 with a soft feel on the surface of the shrink film layer 3, the surface hardness of the shrink label is reduced, which helps to improve the feel of the shrink label. In addition, placing the graphic information layer 2 in the inner layer of the shrink film layer 3 helps to maintain the clarity and durability of the graphic information.
[0032] In some embodiments, the varnish layer 1 is a microbead coating composed of microbeads with a soft touch.
[0033] The microbeads form an uneven structure on the surface of the shrink label, which helps to enhance the soft touch through the elasticity of the microbeads themselves. Furthermore, the gaps between the microbeads allow the microbead coating to deform synchronously with the shrink film layer 3, maintaining the adaptability of the shrink process.
[0034] In some embodiments, the microbead coating is an aqueous acrylic microbead coating.
[0035] The water-based acrylic microbead coating improves the transparency and flexibility of the varnish layer 1, and helps prevent the varnish layer 1 from cracking or peeling off from the shrink film layer 3 during the heat shrinking process of the shrink label.
[0036] In some embodiments, the dry basis dosage of the aqueous acrylic microsphere coating is 1.5-3.5 g / m³. 2 .
[0037] This dry-base dosage range helps to avoid the microsphere coating being too thin to form a continuous coverage, and also helps to avoid the microsphere coating being too thick, which can easily cause the coating to crack due to local stress concentration during shrinkage.
[0038] In some embodiments, the microspheres have the same particle size.
[0039] This configuration facilitates the formation of a uniformly thick varnish layer 1, ensuring a consistent surface feel for the shrink label. Furthermore, the uniform particle size enhances the stacking density of the microspheres within the varnish layer 1, reducing localized stress concentrations or delamination caused by uneven particle distribution during shrinkage.
[0040] In some embodiments, the particle size of the microbeads ranges from 4 to 7 μm.
[0041] Within this particle size range, the microspheres not only produce a soft touch but also help ensure that the varnish layer 1 deforms synchronously with the shrinkage film layer 3 during the shrinkage process, avoiding microsphere detachment or delamination caused by deformation mismatch. In addition, this particle size range facilitates the uniform dispersion of microspheres, which helps to ensure a soft touch.
[0042] In some embodiments, the shrink film layer 3 is a PETG shrink film layer or an OPS shrink film layer.
[0043] The PETG (polyethylene terephthalate-1,4-cyclohexanedimeth yleneterephthalate) shrink film layer provides a smooth and highly transparent substrate for the graphic information layer 2, thus improving the clarity of the displayed graphic information. The OPS (Oriented Polystyrene) shrink film layer has high strength, shape stability, good gloss and transparency, is easy to process, readily colored, has good printability, high printing resolution, and is environmentally friendly.
[0044] In some embodiments, the graphic information layer 2 is a printed layer.
[0045] The graphic information layer 2 is a printing layer, which facilitates the direct printing of graphic information on the surface of the shrink film layer 3, and helps to simplify the production process.
[0046] Another aspect of this disclosure provides a packaging container, which includes a container body and a shrink label provided in this disclosure. The shrink label is configured to be disposed on the exterior of the container body. For example, when the container body is a bottle, the shrink label can be configured to wrap around the exterior of the bottle.
[0047] The packaging container of this disclosure has the advantages of the shrink label of this disclosure.
[0048] The following combination Figure 1 The shrink label of the present disclosure will be described in detail.
[0049] like Figure 1 As shown, the shrink label includes a varnish layer 1 with a soft touch, a shrink film layer 3, and a graphic information layer 2. The varnish layer 1 is disposed on the surface of the shrink film layer 3. The graphic information layer 2 is disposed on the inner layer of the shrink film layer 3.
[0050] Based on the shrink label provided in this disclosure, by providing a varnish layer 1 with a soft touch on the surface of the shrink film layer 3, it is beneficial to improve the surface hardness of the shrink label.
[0051] The varnish layer 1 is a microsphere coating composed of microspheres with a soft texture; the microsphere coating is a water-based acrylic microsphere coating. The dry basis dosage of the water-based acrylic microsphere coating is 1.5-3.5 g / m³. 2 For example, 2.5g / m 2 .
[0052] The waterborne acrylic microspheres have a uniform particle size. The particle size range of waterborne acrylic microspheres is 4-7 μm, for example, 5 μm.
[0053] Image and text information layer 2 is a printing layer.
[0054] In one embodiment, the shrink film layer 3 is a PETG shrink film layer.
[0055] In another embodiment, the shrink film layer 3 is an OPS shrink film layer.
[0056] The shrink label manufacturing method of this embodiment is as follows: the graphic information layer 2 is printed on the shrink film layer 3, the varnish layer 1 is then laminated together with the shrink film layer 3 and the graphic information layer 2, and then the shrink label is cut, joined together, and inspected to finally complete the production.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit them; although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this disclosure or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this disclosure.
