A composite in-mold label

Abstract

This utility model discloses a composite in-mold label, including a label layer, a synthetic paper layer at the lower end of the label layer, and a barrier layer at the lower end of the label layer near the synthetic paper layer. The synthetic paper layer includes a synthetic paper frame adhered to the lower end of the label layer, and the inner side of the synthetic paper frame is filled with padding strips. The upper end of the padding strips has a guide groove. The barrier layer includes an upper polyethylene film adhered to the lower end of the label layer near the synthetic paper frame, and the lower end of the upper polyethylene film is fixedly connected to a warp and weft woven fabric. This composite in-mold label, by conforming the synthetic paper frame to the shape of the bottle, causes the padding strips to compress the guide groove, resulting in deformation of the padding strips. The upper polyethylene film also conforms to the bottle body, further deforming the warp and weft woven fabric. This facilitates better adhesion of the label layer to the inner wall of the bottle, allowing the user to better observe the content marked on the label layer through the bottle.

Description

Technical Field

[0001] This utility model relates to the field of in-mold labeling technology, and in particular to a composite in-mold label. Background Technology

[0002] In-mold labeling involves placing a pre-printed label image (with hot melt adhesive on the back) directly into the molding area of ​​a plastic molding machine. The label and container are then bonded together through blow molding or injection molding to form a complete packaging container. The biggest advantage of using in-mold label containers is that the label and bottle body are on the same surface, making the color graphics and text appear as if they were printed directly onto the bottle surface. Traditional composite in-mold labels have some drawbacks. When using in-mold labels, they need to be affixed to the inner wall of the bottle and follow the shape of the bottle to ensure that the in-mold label fits the shape of the bottle perfectly. In addition, paper in-mold labels are easily damaged and deformed by water, oil, etc., which affects their use. Utility Model Content

[0003] The main objective of this invention is to provide a composite in-mold label that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A composite in-mold label includes a label layer, a synthetic paper layer at the lower end of the label layer, a barrier layer at the lower end of the label layer near the synthetic paper layer, a synthetic paper frame adhered to the lower end of the label layer, a padding strip inside the synthetic paper frame, a guide groove at the upper end of the padding strip, and an upper polyethylene film adhered to the lower end of the label layer near the synthetic paper frame. A warp and weft woven fabric is fixedly connected to the lower end of the upper polyethylene film. A main side strip is adhered to the lower end of the upper polyethylene film near the front of the warp and weft woven fabric, a barrier strip is adhered to the lower end of the upper polyethylene film near the warp and weft woven fabric, a secondary side strip is adhered to the lower end of the upper polyethylene film near the rear of the warp and weft woven fabric, and a lower polyethylene film is adhered to the lower end of the main side strip.

[0005] Preferably, the guide groove is trapezoidal in shape, there are multiple sets of guide grooves, and there are several sets of pad strips, with all sets of pad strips stacked inside the synthetic paper frame.

[0006] Preferably, one end of the upper polyethylene film is fixedly connected to one end of the synthetic paper frame, and the front end of the barrier strip is fixedly connected to the rear end of the main side strip.

[0007] Preferably, the lower end of the barrier strip is adhered to the upper end of the lower polyethylene film near the rear side of the main side strip, the front end of the secondary side strip is fixedly connected to the rear end of the barrier strip, and the lower end of the secondary side strip is adhered to the upper end of the lower polyethylene film near the rear side of the barrier strip.

[0008] Preferably, one end of the lower polyethylene film is fixedly connected to one end of the synthetic paper frame near the lower side of the upper polyethylene film, and the warp and weft woven fabric has a wavy shape.

[0009] Preferably, an adhesive ring is fixedly connected to the upper end of the synthetic paper holder near the outer side of the label layer, and the lower end of the adhesive ring is fixedly connected to the upper end of the upper polyethylene film near the side of the synthetic paper holder, with the label layer located inside the adhesive ring.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. By using a synthetic paper frame to fit the shape of the bottle, the pad strip is squeezed into the guide groove, causing the pad strip to deform. The upper polyethylene film also fits the bottle, causing the warp and weft woven fabric to deform. This allows the label layer to better adhere to the inner wall of the bottle, enabling the user to better observe the contents of the label layer through the bottle.

[0011] 2. Under the action of multiple sets of guide grooves, the gas in the synthetic paper holder is circulated, and under the action of the warp and weft weave, the gas in the barrier layer is circulated, so that the synthetic paper layer and the barrier layer are not affected by the environment inside the bottle, and thus the synthetic paper layer and the barrier layer will not expand, thereby making the label layer firmly adhere to the inner wall of the bottle.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-4 As shown, a composite in-mold label includes a label layer 1, a synthetic paper layer 2 at the lower end of the label layer 1, a barrier layer 3 at the lower end of the label layer 1 near the synthetic paper layer 2, a synthetic paper frame 21 adhered to the lower end of the label layer 1, a pad strip 22 filled inside the synthetic paper frame 21, a guide groove 23 at the upper end of the pad strip 22, and an upper polyethylene film 31 adhered to the lower end of the label layer 1 near the synthetic paper frame 21. A warp and weft woven fabric 36 is fixedly connected to the lower end of the upper polyethylene film 31. A main side strip 32 is adhered to the lower end of the upper polyethylene film 31 near the front of the warp and weft woven fabric 36. A barrier strip 33 is adhered to the lower end of the upper polyethylene film 31 near the side of the warp and weft woven fabric 36. A secondary side strip 34 is adhered to the lower end of the upper polyethylene film 31 near the rear of the warp and weft woven fabric 36. A lower polyethylene film 35 is adhered to the lower end of the main side strip 32.

[0016] In this embodiment, the guide groove 23 is trapezoidal in shape, and there are multiple sets of guide grooves 23. There are also several sets of pad strips 22, and all sets of pad strips 22 are stacked inside the synthetic paper frame 21. One end of the upper polyethylene film 31 is fixedly connected to one end of the synthetic paper frame 21. The front end of the baffle strip 33 is fixedly connected to the rear end of the main side strip 32. The lower end of the baffle strip 33 is adhered to the upper end of the lower polyethylene film 35 near the rear side of the main side strip 32. The front end of the secondary side strip 34 is fixedly connected to the rear end of the baffle strip 33. The lower end of the secondary side strip 34 is adhered to the upper end of the lower polyethylene film 35 near the rear side of the baffle strip 33. One end of the lower polyethylene film 35 is fixedly connected to one end of the synthetic paper frame 21 near the lower side of the upper polyethylene film 31. The warp and weft woven fabric 36 is wavy in shape.

[0017] Specifically, by conforming the synthetic paper holder 21 to the shape of the bottle, the pad strip 22 is pressed against the guide groove 23, causing the pad strip 22 to deform, thus better conforming the synthetic paper holder 21 to the shape of the bottle, and also causing the upper polyethylene film 31 to conform to the bottle, thereby deforming the warp and weft woven fabric 36, thus better conforming the label layer 1 to the inner wall of the bottle. At the same time, multiple sets of guide grooves 23 allow gas to circulate within the synthetic paper holder 21, and under the action of the warp and weft woven fabric 36, the gas within the barrier layer 3 circulates, thus making the synthetic paper layer 2 and the label layer 3 conform to the bottle. The barrier layer 3 is not affected by the internal environment of the bottle, thus preventing the synthetic paper layer 2 and the barrier layer 3 from expanding. This allows the label layer 1 to adhere firmly to the inner wall of the bottle. The synthetic paper holder 21 conforms to the shape of the bottle, causing the pad strip 22 to press against the guide groove 23, resulting in deformation of the pad strip 22. The upper polyethylene film 31 also adheres to the bottle, causing deformation of the warp and weft woven fabric 36. This facilitates better adhesion of the label layer 1 to the inner wall of the bottle, allowing the user to better observe the contents marked on the label layer 1 through the bottle.

[0018] In this embodiment, an adhesive ring 4 is fixedly connected to the upper end of the synthetic paper holder 21 near the outer side of the label layer 1, and the lower end of the adhesive ring 4 is fixedly connected to the upper end of the upper polyethylene film 31 near the side of the synthetic paper holder 21. The label layer 1 is located inside the adhesive ring 4.

[0019] Specifically, first, place label layer 1 on the inner wall of the bottle, then adhere label layer 1 to the inner wall of the bottle, and make the adhesive ring 4 contact the inner wall of the bottle, thereby adsorbing label layer 1 onto the inner wall of the bottle.

[0020] Working principle: In use, first place label layer 1 on the inner wall of the bottle, then adhere label layer 1 to the inner wall of the bottle, ensuring the adhesive ring 4 contacts the inner wall, thus adsorbing label layer 1 onto the inner wall and conforming the synthetic paper holder 21 to the shape of the bottle. This causes the pad strip 22 to press against the guide groove 23, deforming the pad strip 22 and further conforming the synthetic paper holder 21 to the shape of the bottle. The upper polyethylene film 31 also adheres to the bottle, causing the warp and weft woven fabric 36 to deform, further conforming label layer 1 to the inner wall of the bottle. Simultaneously, multiple guide grooves 23 allow gas to circulate within the synthetic paper holder 21, and the warp and weft woven fabric 36 facilitates gas circulation within the barrier layer 3. This prevents the synthetic paper layer 2 and barrier layer 3 from being affected by the internal environment of the bottle, thus preventing damage to the synthetic paper layer 2 and barrier layer 3. The expansion causes the label layer 1 to adhere firmly to the inner wall of the bottle. The synthetic paper holder 21 conforms to the shape of the bottle, causing the pad strip 22 to press against the guide groove 23, resulting in deformation of the pad strip 22. The upper polyethylene film 31 also adheres to the bottle, causing deformation of the warp and weft woven fabric 36. This facilitates better adhesion of the label layer 1 to the inner wall of the bottle, allowing the user to better observe the contents of the label layer 1 through the bottle. Under the action of multiple guide grooves 23, the gas inside the synthetic paper holder 21 circulates, and under the action of the warp and weft woven fabric 36, the gas inside the barrier layer 3 circulates. This prevents the synthetic paper layer 2 and the barrier layer 3 from being affected by the internal environment of the bottle, thus preventing them from expanding and ensuring that the label layer 1 adheres firmly to the inner wall of the bottle.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
