Description

Technical Field

[0001] This utility model relates to the field of composite aluminum foil paper technology, and in particular to a composite aluminum foil paper. Background Technology

[0002] Currently, many families use aluminum foil to pack food such as rice balls and sweet potatoes. Sometimes, to prevent food from falling out of the aluminum foil, people use tape to seal it. However, most families currently use single-layer aluminum foil, which usually tears when the plastic bag is torn open, making it unsuitable for repeated packing. Utility Model Content

[0003] This invention proposes a composite aluminum foil paper, which solves the above-mentioned problems existing in the use of the prior art.

[0004] The technical solution of this utility model is implemented as follows: a composite aluminum foil paper includes an aluminum foil paper layer, a reinforcing layer is fixedly disposed in the middle of the aluminum foil paper layer, an oil-absorbing layer is disposed at one end of the aluminum foil paper, the oil-absorbing layer extends outward, and the oil-absorbing layer is disposed on one side of the reinforcing layer.

[0005] The present invention is further configured such that: the reinforcing layer includes a yarn layer, the yarn layer includes a plurality of interlaced yarns, and an isolation tensile layer is provided on the side of the yarn layer facing away from the aluminum foil.

[0006] The present invention is further configured such that the isolation tensile layer is a first coating layer.

[0007] The present invention is further configured such that a second coating layer is provided on the base surface of the aluminum foil paper facing the yarn layer.

[0008] The present invention is further configured such that the yarn layer and the first coating layer are fixedly disposed on the second coating layer by heat sealing.

[0009] The present invention is further configured such that a waterproof layer is provided on the base surface of the oil-absorbing layer on the side opposite to the aluminum foil layer.

[0010] The present invention is further configured such that the waterproof layer is a third coating layer.

[0011] In summary, the beneficial effects of this utility model are as follows:

[0012] 1. This structure combines the aluminum foil layer with the reinforcing layer, which strengthens the structural strength of the aluminum foil layer and prevents the tape from tearing the aluminum foil layer.

[0013] 2. The yarn layer, the first coating layer, and the second coating layer are fixedly set on the aluminum foil. On the one hand, they can support the aluminum foil and improve its tensile strength. On the other hand, when the packaging paper is packaged, the tape stands on the first coating layer, which can prevent the first coating layer from being torn by the tape. At the same time, the yarn layer can prevent the first coating layer from being pulled away by the tape.

[0014] 3. The oil-absorbing layer is used to prevent oil leakage from the food packaging paper after packaging. Attached Figure Description

[0019] The following will refer to the appendix in the embodiments of this utility model. Figure 1-2 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0020] Example:

[0021] like Figures 1 to 2 As shown, this utility model discloses a composite aluminum foil paper, including an aluminum foil paper layer 1. A reinforcing layer is fixedly disposed in the middle of one side of the base surface of the aluminum foil paper layer 1. The aluminum foil paper is generally glossy on one side and matte on the other side. The matte side is used to contact food. Therefore, the reinforcing layer should be disposed on the glossy side of the base surface of the aluminum foil paper layer 1. The reinforcing layer specifically includes a yarn layer 2, which includes a plurality of crisscrossing yarns 21. At the same time, an isolation tensile layer is disposed on the side of the yarn layer 2 facing away from the aluminum foil paper. The isolation tensile layer is a first coating layer 3.

[0022] Furthermore, a second coating layer 4 is provided on the base surface of the aluminum foil facing the yarn layer 2, and the yarn layer 2 and the first coating layer 3 are fixedly disposed on the second coating layer 4 by heat sealing.

[0023] Furthermore, an oil-absorbing layer 5 is provided at one end of the aluminum foil paper. The oil-absorbing layer 5 extends outward from the end of the aluminum foil paper. At the same time, the oil-absorbing layer 5 should also be provided on the glossy side of the base surface of the aluminum foil paper layer 1. The second coated paper is provided between the oil-absorbing layer 5 and the aluminum foil paper layer 1. In this way, the oil-absorbing layer 5 can be directly fixed to the aluminum foil paper layer 1 by heat sealing.

[0024] Furthermore, a waterproof layer, which is the third coating layer 6, is provided on the base surface of the oil-absorbing layer 5 on the side opposite to the aluminum foil layer 1.

[0025] The above structure is used as follows: place the food in the middle of the matte side of the aluminum foil layer 1, then wrap the end of the aluminum foil layer 1 without the oil-absorbing layer 5 around the food, and then cover the end of the aluminum foil layer 1 with the oil-absorbing layer 5 over the end without the oil-absorbing layer 5, forming a three-fold state. Then roll up the folded aluminum foil layer 1 completely. After rolling, stick the tape on the first coating layer 3 to complete the packaging.

[0026] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.
