AI Technical Summary
Existing shrink labels have poor tactile feel and are prone to slipping off in wet conditions. They also have insufficient heat retention, especially in cold environments where the contents temperature drops rapidly.
A transparent or semi-transparent nonwoven fabric layer is used as the surface layer, combined with an adhesive layer and a shrink film layer. A graphic information layer is set on the shrink film layer. The adhesive layer is used to bond the nonwoven fabric layer to the graphic information layer or the shrink film layer, thereby improving surface roughness and friction, while utilizing the heat insulation properties of the nonwoven fabric layer.
It improves the feel, prevents packaging containers from slipping, and slows down the rate at which the contents cool down in cold environments.

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 package containers, such as bottles, serving both to display information and protect the container itself. Shrink labels can not only package regularly shaped containers, but also fit and wrap irregularly shaped parts of the container body after shrinking.
[0003] In related technologies, shrink labels have a smooth surface, resulting in a poor tactile experience. Furthermore, when holding the shrink label on a packaging container with wet hands, insufficient grip can cause the container to slip. Additionally, shrink labels have poor heat retention, causing the contents of the packaging container to cool rapidly in cold environments. Utility Model Content
[0004] The purpose of this disclosure is to provide a shrink label and packaging container that addresses the problem of poor tactile feel in shrink labels in the related art.
[0005] The first aspect of this disclosure provides a shrink label, including:
[0006] A transparent or semi-transparent non-woven fabric layer is located on the surface of the shrink label;
[0007] The adhesive layer is located on the inner side of the nonwoven fabric layer;
[0008] Shrink film layer, located on the inner side of the adhesive layer; and
[0009] A graphic information layer is disposed on the shrink film layer; wherein...
[0010] The graphic information layer is located on the side close to the adhesive layer, and the non-woven fabric layer is bonded to the graphic information layer through the adhesive layer; or
[0011] The graphic information layer is located on the side away from the adhesive layer, and the non-woven fabric layer and the shrink film layer are bonded together by the adhesive layer.
[0012] In some embodiments of the shrink label,
[0013] The nonwoven layer is a PP nonwoven layer or a PET nonwoven layer; and / or
[0014] The thickness of the nonwoven fabric layer is 10-50 g / m. 2 .
[0015] In some embodiments of the shrink label,
[0016] The shrink film layer is a PETG shrink film layer or an OPS shrink film layer; and / or
[0017] The thickness of the shrink film layer is 20-50 μm.
[0018] In some embodiments of the shrink label, the amount of adhesive applied is 1.5-5 g / m². 2 .
[0019] In some embodiments of the shrink label, the graphic information layer is a printed layer.
[0020] A second aspect of this disclosure provides a packaging container, comprising:
[0021] container body; and
[0022] The shrink label described in the first aspect of this disclosure is disposed on the container body.
[0023] Based on the shrink label provided in this disclosure, the shrink label includes a non-woven fabric layer, an adhesive layer, a shrink film layer, and a graphic information layer. The surface layer of the shrink label is a transparent or semi-transparent non-woven fabric layer. The adhesive layer and shrink film layer are located inside the non-woven fabric layer. The graphic information layer is disposed on the shrink film layer and located on the side of the shrink film layer closer to or further away from the adhesive layer. The non-woven fabric layer is bonded to the graphic information layer or the shrink film layer via the adhesive layer. The non-woven fabric layer on the surface of this shrink label helps to increase the surface roughness and friction, thereby improving the feel and preventing the packaging container with the shrink label from slipping from the hand when hands are wet or slippery. Additionally, in cold environments, the non-woven fabric layer of the shrink label can provide some insulation, helping to slow down the rate of temperature drop of the contents inside the packaging container with the shrink label.
[0024] The packaging container disclosed herein includes the shrink label of this disclosure, thereby having the advantages of the shrink label of this disclosure.

[0035] like Figure 1 and Figure 2 As shown, this disclosure provides a shrink label. The shrink label includes a transparent or semi-transparent nonwoven fabric layer 1, an adhesive layer 2, a shrink film layer 3, and a graphic information layer 4. The nonwoven fabric layer 1 is located on the surface of the shrink label. The adhesive layer 2 is located on the inner side of the nonwoven fabric layer 1. The graphic information layer 4 is disposed on the shrink film layer 3. Specifically, the graphic information layer 4 is located on the side closer to the adhesive layer 2, and the nonwoven fabric layer 1 and the graphic information layer 4 are bonded together by the adhesive layer 2; or the graphic information layer 4 is located on the side farther from the adhesive layer 2, and the nonwoven fabric layer 1 and the shrink film layer 3 are bonded together by the adhesive layer 2.
[0036] Based on the shrink label provided in this embodiment, the shrink label includes a non-woven fabric layer 1, an adhesive layer 2, a shrink film layer 3, and a graphic information layer 4. The surface layer of the shrink label is a transparent or semi-transparent non-woven fabric layer 1. The adhesive layer 2 and the shrink film layer 3 are located on the inner side of the non-woven fabric layer 1. The graphic information layer 4 is disposed on the shrink film layer 3 and located on the side of the shrink film layer 3 closer to or further away from the adhesive layer 2. The non-woven fabric layer 1 is bonded to the graphic information layer 4 or the shrink film layer 3 through the adhesive layer 2. The non-woven fabric layer 1 on the surface of the shrink label helps to improve the surface roughness and friction of the shrink label, thereby improving the feel and preventing the packaging container with the shrink label from slipping from the hand when the hand is wet. In addition, in cold environments, the non-woven fabric layer 1 of the shrink label can play a certain role in heat preservation, which helps to slow down the temperature drop of the contents inside the packaging container.
[0037] In some embodiments, the nonwoven layer 1 is a PP nonwoven layer or a PET nonwoven layer.
[0038] PP (polypropylene) nonwoven fabric has high flexibility, which helps to prevent the nonwoven fabric layer 1 from delaminating or warping from the adhesive layer 2 after shrinking the label. PET (polyethylene glycol terephthalate) nonwoven fabric has a high shrinkage rate, which helps to maintain uniform shrinkage during heat shrinkage, reducing uneven deformation in different parts of the shrink label and preventing the graphic information layer 4 from displaying information correctly.
[0039] In some embodiments, the thickness of the nonwoven layer 1 is 10-50 g / m². 2 .
[0040] This thickness range helps to prevent the nonwoven fabric layer 1 from being too thick, which would increase the resistance to heat shrinkage and help to prevent the nonwoven fabric layer 1 from delaminating or warping from the adhesive layer 2 after the shrink label shrinks. This thickness range also helps to prevent the nonwoven fabric layer 1 from being too thin, which would make it easy to break.
[0041] In some embodiments, the shrink film layer 3 is a PETG shrink film layer or an OPS shrink film layer.
[0042] The PETG (polyethylene terephthalate-1,4-cyclohexanedimeth yleneterephthalate) shrink film layer has a high surface polarity, which is beneficial for strengthening the adhesion between the shrink film layer 3 and the adhesive layer 2. In addition, the PETG shrink film layer helps to provide a smooth and highly transparent substrate for the graphic information layer 4, which is beneficial for improving the clarity of the graphic information displayed on the graphic information layer 4. The OPS (Oriented Polystyrene) shrink film layer has high strength, shape stability, good gloss and transparency, is easy to process, easy to color, has good printability, high printing resolution, and is relatively environmentally friendly.
[0043] In some embodiments, the thickness of the shrink film layer 3 is 20-50 μm.
[0044] Within this thickness range, the thermal shrinkage stress distribution of the shrink film layer 3 is more uniform, which helps to reduce the difference in shrinkage rate caused by excessive local thickness and helps to avoid deformation or edge warping of the shrink label.
[0045] In some embodiments, the amount of adhesive layer 2 is 1.5-5 g / m². 2 .
[0046] Setting a lower limit for adhesive application helps ensure the bonding strength between the nonwoven fabric layer 1 and the shrink film layer 3 or the graphic information layer 4, and helps prevent the shrink label from peeling off due to insufficient adhesive application during the shrinking process. Setting an upper limit for adhesive application helps prevent stress concentration caused by excessive thickness of the adhesive layer 2 due to heat shrinkage, and helps reduce wrinkling or curling of the shrink label caused by the mismatch between the shrinkage rate of the adhesive layer 2 and the shrink film layer 3 during curing and shrinkage.
[0047] In some embodiments, the graphic information layer 4 is a printed layer.
[0048] The graphic information layer 4 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.
[0049] 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 being disposed on the container body. The container body is, for example, a bottle or a box.
[0050] The packaging container of this disclosure has the advantages of the shrink label of this disclosure.
[0051] The following combination Figure 1 and Figure 2 The shrink label of the present disclosure will be described in detail.
[0052] like Figure 1 In the illustrated embodiment, the shrink label includes a transparent or semi-transparent nonwoven fabric layer 1, an adhesive layer 2, a shrink film layer 3, and a graphic information layer 4. The nonwoven fabric layer 1 is located on the surface of the shrink label. The adhesive layer 2 and the shrink film layer 3 are located on the inner side of the nonwoven fabric layer 1. The graphic information layer 4 is disposed on the shrink film layer 3, located near the adhesive layer 2, and the nonwoven fabric layer 1 and the graphic information layer 4 are bonded together by the adhesive layer 2. The graphic information layer 4 is a printed layer.
[0053] The shrink label of this embodiment includes a non-woven fabric layer 1, an adhesive layer 2, a shrink film layer 3, and an image and text information layer 4. The surface of the shrink label is provided with a transparent or semi-transparent non-woven fabric layer 1. The adhesive layer 2 and the shrink film layer 3 are located inside the non-woven fabric layer 1. The image and text information layer 4 is disposed on the shrink film layer 3 and located on the side of the shrink film layer 3 closest to the adhesive layer 2. The non-woven fabric layer 1 is bonded to the image and text information layer 4. The non-woven fabric layer 1 on the surface of this shrink label helps to increase the surface roughness and friction of the shrink label, thereby improving the feel and preventing the packaging container with the shrink label from slipping from the hand when hands are wet. Furthermore, in cold environments, the non-woven fabric layer 1 of the shrink label helps to insulate, slowing down the rate of temperature drop of the contents inside the packaging container containing the shrink label. The image and text information layer 4 is a printed layer, which simplifies the production process.
[0054] Nonwoven layer 1 is either a PP nonwoven layer or a PET nonwoven layer. The thickness of nonwoven layer 1 is 10-50 g / m². 2 For example, 30g / m 2 .
[0055] Shrink film layer 3 is a PETG shrink film layer or an OPS shrink film layer. The thickness of shrink film layer 3 is 20-50 μm, for example, 30 μm.
[0056] The amount of adhesive applied to layer 2 is 1.5-5 g / m². 2For example, the amount of adhesive applied is 3.5g / m². 2 .
[0057] like Figure 2 In the illustrated embodiment, with Figure 1 The difference in the embodiment shown is that the graphic information layer 4 is disposed on the shrink film layer 3 and is located on the side away from the adhesive layer 2, and the nonwoven fabric layer 1 and the shrink film layer 3 are bonded together by the adhesive layer 2.
[0058] The shrink label manufacturing method of this embodiment is as follows: a composite process is adopted, in which a non-woven fabric layer 1 and a shrink film layer 3 printed with graphic information layer 4 are bonded together by an adhesive layer 2. After the adhesive layer 2 is cured and shaped, the shrink label is cut, joined, and inspected to complete the production.
[0059] 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.
