Description

Technical Field

[0002] Aluminum-reinforced base film is a thin film material with an aluminum layer added to the base film to enhance its performance. It usually includes a base film layer, an aluminum layer and a possible adhesive layer or reinforcement structure. It is widely used in fields such as construction and packaging.

Compared with the existing technology, the base film of the utility model has a more reasonable structural setting, and the reinforcement layer structure is reasonably set. The main reinforcement ribs and side reinforcement ribs can improve the strength of the aluminum-plated layer, and the reinforcement strips make the aluminum-plated layer reliably connected. The aluminum-plated layer has good strength and is not easy to break after a collision. The aluminum-plated layer and the reinforcement layer are reliably connected and have high adhesion. Large-scale peeling of the aluminum-plated layer will not occur. The transparent protective layer can protect the aluminum-plated layer and extend its service life. The structural design is reasonable, the structure is simple, and the practicality is good.

[0004] However, the above-mentioned base membrane improves the connection stability between it and the aluminum-plated layer through the reinforcement ribs provided inside, but the reinforcement ribs are arranged longitudinally and cannot effectively protect the base membrane as a whole from tensile stress, making the base membrane prone to rupture during the transverse stretching process, thereby reducing the strength of the base membrane assembly.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the utility model discloses an aluminum-plated layer enhanced base film.

[0032] Example 1

[0033] The utility model provides Figure 1-5 An aluminum-plated layer reinforced base film shown includes a base film layer 1 and an aluminum-plated layer 2. The aluminum-plated layer 2 is arranged above the base film layer 1. Two symmetrically arranged support layers 3 are arranged between the base film layer 1 and the aluminum-plated layer 2. The two support layers 3 are both PET film layers. The two support layers 3 are internally provided with anti-tensile structures. An adhesive layer 5 is provided at the bottom of the base film layer 1. The adhesive layer 5 is bonded between the aluminum-plated layer 2 and the side close to the upper support layer 3. The upper surface of the aluminum-plated layer 2 is covered with a protective layer 4.

[0034] During the manufacture of the base film, the aluminum-plated layer 2 is stably connected to the base film layer 1 through the adhesive layer 5. At the same time, with the setting of the two support layers 3, the tensile-resistant structure inside the support layer 3 can prevent the base film from breaking when subjected to transverse stretching, thereby ensuring the use strength of the base film.

[0035] Example 2

[0036] Example 2 is based on Example 1 in order to make the anti-tensile structure able to operate stably. Figure 2-4As shown, the anti-stretching structure includes an anti-stretching ring 6 and a connecting film belt 7. The connecting film belt 7 is composed of a stretching portion 8 and two annular portions 9. The two annular portions 9 are respectively provided on both sides of the stretching portion 8 and are integrally connected to the stretching portion 8. The annular portion 9 is provided through the side of the anti-stretching ring 6. The side of the anti-stretching ring 6 is provided with multiple groups of symmetrically arranged through-holes 11. The number of each group of through-holes 11 is 2. The side of the anti-stretching ring 6 is slidably provided in the through-holes 11.

[0037] The upper and lower surfaces of the stretching part 8 are fixed with adhesive parts 10, which are integrated with the surface of the connecting film belt 7. The adhesive part 10 is bonded between the two supporting layers 3, and the side surfaces of the connection between the annular part 9 and the stretching part 8 are provided with two symmetrically arranged anti-tensile arc surfaces 14.

[0038] After the anti-stretching structure is arranged inside the entire base film, when the base film is subjected to transverse stretching, since the stretching portion 8 of the connecting film belt 7 is connected to the two supporting layers 3, when the base film is stretched, the two stretching portions 8 cooperate with the annular portion 9 to pull the anti-pull ring 6. Since the annular portion 9 cooperates with the through hole 11 to pull and deform the anti-pull ring 6 during the stretching process, since the anti-pull ring 6 is arranged in a ring shape, it can effectively offset and buffer the tensile force on all sides in the transverse direction, thereby protecting the base film from breaking when stretched.

[0039] Example 3

[0040] Example 3 is based on Example 2 in order to make the connecting film strip 7 and the supporting layer 3 integrally arranged so that the tension ring 6 can be stretched when the base film is stretched. Figure 3 and Figure 5 As shown, a bonding groove 12 is provided on the top of the bonding member 10, and the interior of the bonding groove 12 is filled with a bonding liquid 13, which bonds with the support layer 3, and the upper and lower surfaces of the tension ring 6 are in contact with the two support layers 3 on the side close to each other.

[0041] Since the adhesive member 10 is integrally arranged with the connecting film tape 7, the supporting layer 3 is fixed to the adhesive member 10 under the bonding action of the adhesive liquid 13, so that the supporting layer 3, the adhesive member 10 and the connecting film tape 7 are integrally arranged. At this time, the position of the tension ring 6 is not restricted and can be stably pulled, and the lateral stretching of the base film can be effectively offset, thereby ensuring the use effect of the base film.

[0042] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
