Description

Technical Field

[0001] The utility model relates to the field of aluminum-plated films, in particular to an aluminum-plated film structure. Background Art

[0002] Aluminized film is a flexible packaging material that is formed by vacuum coating a layer of aluminum on the surface of a plastic film. Because it has the properties of both plastic film and metal, it is a cheap, beautiful, high-performance and practical packaging material.

[0003] The thin film layer of the aluminized film has good tensile flexibility and bendability, but the aluminum film layer is prone to cracking and peeling during the stretching and bending process (a matte aluminized composite film with application number 202020442889.X also provides a relevant introduction to this technical problem in the technical background). The purpose of the utility model is to improve the existing aluminized film structure to alleviate the cracking and peeling problems of the aluminum film during the stretching and bending of the aluminized film. Utility Model Content

[0004] The purpose of the utility model is to provide an aluminum-plated film structure to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: it includes a liquid silicone layer, a plating layer and a base layer, the plating layer is located on the top surface of the liquid silicone layer, an aluminum film layer is provided on the top surface of the plating layer, a first incision is provided on the plating layer to divide the plating layer and the aluminum film layer into a plurality of independent individuals of equal specifications, the base layer is located on the bottom surface of the liquid silicone layer, a second incision is provided on the base layer to divide the base layer into a plurality of independent individuals of equal specifications, and the elastic modulus of the liquid silicone layer is greater than the elastic modulus of the plating layer and the base layer.

[0006] To optimize the above technical solution, further measures are taken: the first incision on the receiving layer corresponds to the second incision on the base layer, ensuring that the receiving layer and the base layer can be deformed synchronously along the first incision and the second incision when the aluminum-coated film is stretched.

[0007] As a further improvement to the above technical solution: the first incision and the second incision are distributed in a honeycomb shape, and the tensile properties of the honeycomb incision in all directions are the same without any orientation difference.

[0008] As a further improvement of the technical solution: the edges of the contact surfaces between the independent individuals on the coating layer and the base layer and the liquid silicone layer are chamfered. The purpose of this setting is to reduce the influence of the liquid silicone layer on the top of the coating layer and the bottom of the base layer when the aluminum-coated film is stretched, and to reduce the traction of the liquid silicone layer.

[0009] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0010] The utility model provides an aluminum-plated film structure, based on the difference in elastic modulus between the liquid silicone layer and the plating layer and the base layer, so that the elastic deformation generated during the stretching and bending of the aluminum-plated film is concentrated on the liquid silicone layer, and the aluminum film layer will migrate along the first incision and be less affected by the stretching and bending, which helps to alleviate the cracking and peeling of the aluminum film caused by stretching and bending.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-4 The utility model provides an aluminum-plated film structure, including a liquid silicone layer 1, a receiving layer 2 and a base layer 3, the receiving layer 2 is located on the top surface of the liquid silicone layer 1, an aluminum film layer 201 is provided on the top surface of the receiving layer 2, and a first incision 202 is opened on the receiving layer 2 to divide the receiving layer 2 and the aluminum film layer 201 into a plurality of independent individuals of equal specifications.

[0020] The base layer 3 is located on the bottom surface of the liquid silicone layer 1 . A second incision 301 is provided on the base layer 3 to divide the base layer 3 into a plurality of independent individuals of equal specifications. The elastic modulus of the liquid silicone layer 1 is greater than that of the plating layer 2 and the base layer 3 .

[0021] The liquid silicone layer 1 refers to a material layer composed of liquid silicone, which has good tear resistance, heat resistance, aging resistance and resilience. It belongs to the prior art content and is known to those skilled in the art, so its specific composition and mechanism of action will not be further explained.

[0022] The specific materials of the coating layer 2 and the base layer 3 are not necessary technical features, nor are they the content that the applicant wants to protect. Therefore, no further introduction is made to their materials. Technical personnel can choose different types of materials according to actual needs in specific implementations. As long as they can meet the above requirements, they can be applied without substantial impact on the technical effects.

[0023] Working principle: the aluminized film is in a stretched state. Since the tensile elasticity of the liquid silicone layer 1 is better than that of the supporting layer 2 and the base layer 3, the deformation generated during the stretching and bending of the aluminized film will be concentrated on the liquid silicone layer 1, and the supporting layer 2 and the aluminum film layer 201 will be less affected by the stretching and bending of the aluminized film. During the stretching and bending process, the supporting layer 2 and the aluminized film will unfold along the first incision 202, and the aluminized film on the supporting layer 2 will not be easily affected by the stretching and bending and will not be peeled off from the supporting layer 2.

[0024] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
