Description

Technical Field

[0001] The utility model relates to the field of packaging materials, in particular to a shrink sleeve label with a window opening effect. Background Art

[0002] Heat shrink sleeves are a commonly used packaging material. The structure of the heat shrink sleeves currently used is shown in patent publication document CN213036301U. The heat shrink sleeve film of this structure is mainly composed of a film body (numbered 1 in the document) and a paper strip layer (numbered 3 in the document) composited together by an adhesive layer, and there are no openings on the film body and the paper strip layer, so the shrink sleeve of this structure has a good light-shielding effect. However, when this shrink sleeve is used on a fully labeled beverage bottle (i.e., the bottle body of the beverage bottle is completely covered by the sleeve), people cannot observe the state of the beverage in the beverage bottle from the outside. Utility Model Content

[0003] In view of the above problems, the utility model provides a shrink sleeve label with a window opening effect.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A shrink sleeve label with a window effect comprises a printed film, an adhesive layer and a heat shrink film, wherein the printed film and the heat shrink film are compounded together by the adhesive layer, the printed film is a milky white printed film, the printed film, the adhesive layer and the heat shrink film are all provided with through holes, and the through holes of the printed film, the through holes of the adhesive layer and the through holes of the heat shrink film are in a connected state.

[0006] In this shrink sleeve label, a printed film and a heat shrink film are compounded through an adhesive layer, and the printed film adopts a milky white printed film. The milky white printed film itself has good light-shielding properties, which gives the entire shrink sleeve label good light-shielding properties. At the same time, in this shrink sleeve label, through holes are opened on the printed film, the adhesive layer and the heat shrink film, and the through holes on the printed film, the through holes on the adhesive layer and the through holes on the heat shrink film are in a through state, which is equivalent to providing a through hole on the shrink sleeve label (that is, equivalent to opening a window on the shrink sleeve label). When this shrink label is set on the beverage bottle, the beverage in the beverage bottle can be directly observed with the help of the through hole on the shrink sleeve label. Therefore, after this shrink sleeve label is set on the beverage bottle, it is equivalent to setting a light-shielding sleeve label with a window on the beverage bottle (wherein the area of ​​the window accounts for a relatively small area of ​​the light-shielding sleeve label), which can not only play a good covering role on the beverage in the beverage bottle, but also directly check the state of the beverage in the beverage bottle with the help of the through hole on the shrink sleeve label.

[0007] In summary, in this shrink sleeve label, a printed film and a shrink film are compounded by an adhesive layer, and through holes are opened on the printed film, the shrink film and the adhesive layer, and the through holes on the printed film, the shrink film and the adhesive layer are connected, which is equivalent to opening a window on the opaque shrink sleeve label. Therefore, when it is set on a transparent beverage bottle, it can not only play a good light-shielding effect on the beverage in the beverage bottle, but also can observe the state of the beverage in the beverage bottle through the through hole.

[0008] Optionally, the printing film is provided with an ink printing layer, and the ink printing layer and the adhesive layer are respectively located on two sides of the printing film.

[0009] The required graphic information is printed on the printing film by using ink, and the ink forms an ink printing layer on the printing film. Specifically, the ink printing layer does not cover the through holes on the printing film.

[0010] Optionally, the through holes are circular through holes, and the through holes of the printed film, the through holes of the adhesive layer and the through holes of the heat shrinkable film are located on the same virtual cylindrical surface.

[0011] The specific shape of the through hole may also be an ellipse or an oblong shape, as long as it has no sharp corners.

[0012] Optionally, the printed film is a PETG film.

[0013] Optionally, the heat shrinkable film is a PETG film.

[0014] Both the printed film and the heat shrink film are made of PETG film, which can ensure that this type of shrink sleeve has a long service life and can be quickly shrunk on the bottle body during heat shrinkage.

[0015] In order to ensure that the printed film and the heat shrinkable film can be stably laminated together, the adhesive used in the adhesive layer of this shrink sleeve label is a solvent-free adhesive.

[0016] Optionally, the printed film has a thickness of 45um-50μm.

[0017] Optionally, the thickness of the heat shrinkable film is 45um-50μm.

[0018] Optionally, the thickness of the adhesive layer is 1 um-2 μm.

[0019] The adhesive layer has such a thickness that it can ensure that the printed film and the heat shrinkable film can be stably laminated together, and at the same time, the adhesive layer does not affect the heat shrinkage during heat shrinkage.

[0020] The beneficial effects of the utility model are: it can not only play a good light shielding effect on the beverage in the beverage bottle, but also can observe the state of the beverage in the beverage bottle through the through hole. BRIEF DESCRIPTION OF THE DRAWINGS
