Description

Technical Field

[0001] The invention relates to the technical field of aluminized films, and more specifically to a double-layer composite aluminized film. Background Art

[0002] Double-layer composite aluminized film usually refers to a film composed of two layers of different materials, one of which is aluminum film and the other can be plastic or other suitable materials. This composite film is often used in packaging, building materials or electronic products.

[0003] When the existing double-layer composite aluminized film is used, the bonding strength between the aluminized layer and the base film is relatively poor.

[0004] Therefore, there is an urgent need for a double-layer composite aluminum-plated film that can achieve strong fastness between the aluminum-plated layer and the base film. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a double-layer composite aluminized film to solve the defect that the bonding firmness between the aluminized layer and the base film is relatively poor when the double-layer composite aluminized film of the prior art is used.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] A double-layer composite aluminized film, whose structure includes a base film, the upper and lower surfaces of the base film are both composited with an aluminized film layer by glue, a protective layer arranged on the surface of the aluminized film layer, a connecting line located between the base film and the aluminized film layer, and edge sealing arranged on the surfaces of both sides of the base film, the aluminized film layer and the protective layer.

[0008] As a further solution of the present invention, the connecting lines are of bow-shaped structure and are evenly and equidistantly arranged.

[0009] As a further solution of the present invention, the protective layer is made of transparent material.

[0010] As a further solution of the present invention, a plurality of grooves are provided at the position where the edge seal contacts the surface of the protective layer, so as to realize the operation of removing water from the surface of the aluminum-plated film.

[0011] As a further solution of the present invention, the groove is arranged in a shallow groove frame structure.

[0012] As a further solution of the present invention, the connecting wires are respectively embedded in the aluminized film layer and the base film to strengthen the bonding between the base film and the aluminized film.

[0013] Advantageous Effects of the Invention

[0014] Compared with the traditional double-layer composite aluminum-plated film, the present invention has the following beneficial effects:

[0015] In the present invention, a bow-shaped connecting line is set between the base film and the aluminum-plated film layer, and glue is used to bond the aluminum-plated film layer and the base film, so that the medium acts as an intermediate, thereby enhancing the temporal firmness of the two. At the same time, the grooves set toward the surface of the protective layer in conjunction with the edge sealing are used to achieve the operation of dewatering the surface of the aluminum-plated film.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Example:

[0024] like Figure 1-Figure 3 As shown, the present invention provides a technical solution for a double-layer composite aluminum-plated film:

[0025] As shown in the figure, a double-layer composite aluminum-plated film has a structure including a base film 1, the upper and lower surfaces of the base film are compounded with an aluminum-plated film layer 2 by glue, a protective layer 3 arranged on the surface of the aluminum-plated film layer 2, a connecting line 4 located between the base film 1 and the aluminum-plated film layer 2, and edge sealing 5 arranged on the surfaces of both sides of the base film 1, the aluminum-plated film layer 2 and the protective layer 3.

[0026] The connecting lines 4 are of a bow-shaped structure and are arranged evenly and equidistantly.

[0027] The protective layer 3 is made of transparent material.

[0028] A plurality of grooves 51 are provided at the position where the edge seal 5 contacts the surface of the protective layer 3, for achieving the operation of removing water from the surface of the aluminum-plated film.

[0029] The groove 51 is provided with a shallow groove frame structure.

[0030] The connecting wires 4 are respectively embedded in the aluminized film layer 2 and the base film 1 to strengthen the bonding between the base film and the aluminized film.

[0031] The specific implementation principle is as follows: the base film 1 and the aluminized film layer 2 are connected by gluing. Since the connecting line 4 is respectively connected to the base film 1 and the aluminized film layer 2 in an embedded manner, the connecting line 4 is also synchronously glued while the two are glued together, thereby strengthening the bonding strength between the two. The protective layer 3 cooperates with the surface of the aluminized film layer 2 to achieve a protective effect. The edge sealing 5 wraps the sides of the base film 1, the aluminized film layer 2 and the protective layer 3. The grooves 51 set on the surface of the edge sealing 5 are used to remove water retained on the surface of the protective layer 3.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
