Abstract
The utility model discloses a shrink label of complex film, include outer transparent film, be located the picture and text information layer of outer transparent film lower surface, be located the compound glue layer of picture and text information layer below, still including being located the interior film of compound glue layer below, interior film with the shrink curve of outer transparent film is similar. The two layers of shrink films can protect the patterns printed on the inner film and can also be coated with glue at any position, so that the completeness of the patterns and the fit of the films after the films are fitted are guaranteed, and meanwhile, the outer transparent film and the milky white film are combined, so that the delicate patterns printed on the outer transparent film can be reserved, and the high covering power of the milky white film can be reserved.
Description
Technical Field
The utility model belongs to label preparation field especially relates to a shrink label of complex film.
Background
The shrink label can fully utilize the surface of the whole shrink label to reproduce and transmit images and information, thereby greatly enhancing the shelf attraction of the packaged product.
The prior shrink labels all adopt surface printing (patterns are printed inside and patterns are printed outside), and when the patterns are printed by using a transparent film, the patterns are easy to damage. When the transparent film is internally printed, a gluing area is required to be reserved on the transparent film, the gluing area cannot be adjusted after being fixed, when the gluing area is too wide, glue can be dissolved at the edge of the pattern, and when the gluing area is too narrow, the transparent film cannot be attached after being matched, so that the appearance is affected. When the product package needs a milky white film with high covering power, surface printing is needed, and a white gap is left to avoid a pattern area during adhesion, so that the appearance is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a shrink label of complex film solves among the prior art when using transparent film to carry out the table seal, and the pattern receives destruction easily. When the inner printing is carried out, the glue with too wide glue can be dissolved to the edge of the pattern, and the glue with too narrow glue can not be attached after closing the palm, thereby affecting the beauty. When the opal film is used, surface printing is required, and a 'white gap' is left in the bonding process because a pattern area needs to be avoided, so that the appearance is influenced.
The purpose of the utility model can be realized by the following technical scheme:
a shrinkage label of a composite film comprises an outer transparent film, a picture and text information layer positioned on the lower surface of the outer transparent film, a composite glue layer positioned below the picture and text information layer, and an inner film positioned below the composite glue layer, wherein the shrinkage curve of the inner film is similar to that of the outer transparent film.
Further: the outer transparent film is made of a PVC transparent film, and the inner film is made of a PVC transparent film or a PET opal film.
Further, the method comprises the following steps: the outer transparent film is a PETG transparent film, and the inner film is a PETG transparent film or a PETG opal membrane.
Further: the thickness of the outer transparent film is 15 mu-50 mu, and the thickness of the inner film is 15 mu-50 mu.
Further: the outer transparent film is internally printed to form a graphic information layer.
Further, the method comprises the following steps: the glue coating amount of the composite glue layer is 2 grams per square meter to 5 grams per square meter.
The utility model has the advantages that: the two layers of shrink films can protect the patterns printed in the film and can also be coated with glue at any position, so that the integrity of the patterns and the fit of the film after the film is fitted are ensured, and meanwhile, the combination of the outer transparent film and the opal film is used, so that the exquisite patterns printed in the outer transparent film can be reserved, and the high covering power of the opal film can be reserved.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic view of a shrink label of the composite film of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Example 1
Fig. 1 shows, the utility model relates to a shrink label of complex film, including outer transparent film layer 1, be located the picture and text information layer 2 of outer transparent film 1 lower surface, be located the compound glue layer 3 of picture and text information layer 2 below, still including being located the interior film 4 of compound glue layer 3 below, interior film 4 is similar with outer transparent film 1's shrink curve.
In the embodiment, the outer transparent film 1 is a PVC transparent film with the thickness of 15 mu-50 mu, the outer PVC transparent film 1 is internally printed to form the image-text information layer 2, the inner film 4 is a PVC transparent film with the thickness of 15 mu-50 mu, the double-layer PVC transparent film can enable the pattern printed in the inner layer to be more exquisite, and the shrink label can be applied to a packaging structure with low requirement on covering power.
When the product has higher requirement on the covering power, the inner film 4 is a PET (polyethylene terephthalate) latex white film with the thickness of 15 mu-50 mu, and the shrink label can be applied to a packaging structure with high requirement on the covering power.
Because both sides are shrink films, the glue can be coated at any position, the integrity of patterns and the fit of the films after hand closing are ensured, the inner film 4 is coated with the composite glue with the glue coating amount of 2 g/square meter to 5 g/square meter, and the outer transparent film 1 and the inner film 4 are combined in a laminating way through a composite process. Because the temperature requirement of the compounding process is low, in order to obtain a low pressing temperature, in this embodiment, the temperature requirement of the adopted compounding roller is less than or equal to 50 ℃. And curing at normal temperature, and performing the conventional processes of splitting, closing hands, inspecting and packaging the shrink labels after curing to finish production.
Example 2
The difference between the embodiment and the embodiment 1 is as follows: the outer transparent film 1 is a PETG transparent film, and the inner film 4 is a PETG transparent film or a PETG opal film, and the rest is the same as example 1. This embodiment is applied to a packaging structure requiring high shrinkability.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
