[0029] 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.
[0030] The embodiment of the utility model discloses a reinforced hollow fiber aluminum-plated base membrane.
[0031] Example 1

[0033] Reference Figure 1-5The first reinforcing layer 2 and the second reinforcing layer 3 are each provided with a transverse first arc groove on the side close to each other, and a first hollow cavity is commonly provided between the corresponding two first arc grooves. Each first reinforcing rib 6 is respectively transversely arranged inside the first hollow cavity. The second reinforcing layer 3 and the third reinforcing layer 4 are each provided with a plurality of second arc grooves longitudinally on the side close to each other, and a second hollow cavity is commonly provided between the corresponding two second arc grooves. Each second reinforcing rib 7 is respectively longitudinally arranged inside the second hollow cavity, and each first reinforcing rib 6 and each second reinforcing rib 7 are nano copper wires.
[0034] The copper wire has high strength, so each first reinforcing rib 6 can be used to improve the overall strength of the base film in the transverse direction, and the second reinforcing rib 7 can be used to improve the overall strength of the base film in the longitudinal direction, so as to prevent the packaging bag made therefrom from being damaged due to pulling during storage and access. At the same time, the copper wire has a certain conductivity, thereby preventing the base film from generating static electricity during use.
[0035] Example 2
[0036] Based on the first embodiment, Figure 1-2 An adhesive layer 8 is provided between the third reinforcing layer 4 and the aluminum-plated layer 5. The aluminum-plated layer 5 is adhered to the lower surface of the third reinforcing layer 4 through the adhesive layer 8. The adhesive layer 8 is acrylic adhesive.

[0038] Example 3
[0039] Based on the first embodiment, Figure 1-2 The upper surface of the base layer 1 is provided with a printing layer 9 by a printing process, and the base layer 1 is a PET film.
[0040] PET film is a packaging film with relatively comprehensive performance. It has good transparency, gloss, good air tightness and aroma retention. At the same time, food pictures and information can be printed on the upper surface of the base layer 1, that is, the printing layer 9, using the printing process.

[0043] Example 5
[0044] Based on the first embodiment, Figure 1-2 The aluminum plating layer 5 is aluminum foil, and a plurality of grooves are provided on the lower surface of the aluminum plating layer 5.
[0045] The aluminum foil has strong light-shielding and UV-proof properties, thereby extending the shelf life of the food inside. At the same time, each groove can prevent the object inside the aluminum foil from sticking to the aluminum foil.
