Description

Technical Field

[0001] This utility model relates to the field of packaging paper technology, specifically to a fluorocarbon-free packaging paper. Background Technology

[0002] Packaging paper refers to paper used for packaging; it is characterized by high strength, low moisture content, low air permeability, non-corrosiveness, and a certain degree of water resistance, while also being aesthetically pleasing. Paper used for food packaging must also be hygienic, sterile, and free of contaminants and impurities.

[0003] Existing packaging paper has a printing layer to facilitate printing by users. However, the printing layer is mostly made of plastic film, which is not easily degraded and is difficult to separate, thus affecting the decomposition of the paper. In addition, to prevent small amounts of oil or water from wetting the packaging paper, existing food packaging paper usually has a waterproof and oil-proof liquid coated on its surface to act as a barrier. However, the waterproof and oil-proof liquid will reduce the degradation rate of food packaging paper during degradation. Utility Model Content

[0004] The purpose of this invention is to provide a fluorocarbon-free packaging paper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fluorocarbon-free packaging paper, comprising a paper base layer: a first waterproof layer is provided on the top of the paper base layer, a second waterproof layer is provided on the bottom of the paper base layer, a nylon mesh and a degradation layer are provided on the top of the first waterproof layer, a printing layer is provided on the top of the nylon mesh and the degradation layer, a reinforcing layer is provided on the bottom of the second waterproof layer, and an oil-resistant layer is provided on the bottom of the reinforcing layer.

[0006] By adopting the above technical solution, after the food packaging paper has been used, due to the creases on the paper, users can tear it along the creases to expose the nylon mesh inside. Pulling the nylon mesh then cuts the paper, thereby damaging the oil-proof layer. This breaks down the overall structure of the paper base layer, first waterproof layer, second waterproof layer, reinforcing layer, and oil-proof layer, allowing it to fully contact the outside environment and increasing the degradation rate of the food packaging paper. Furthermore, the presence of waterproof adhesive, first oil-proof adhesive, second oil-proof adhesive, and an oil-proof layer on the food packaging paper prevents oil or water from wetting it. The nylon mesh also facilitates the separation of the printing layer from the food packaging paper, promoting its degradation.

[0007] Preferably, the paper base layer, the first waterproof layer, the second waterproof layer, the reinforcing layer, the oil-proof layer, the nylon mesh, the degradable layer, and the printing layer constitute the packaging paper body.

[0008] Preferably, the top and bottom of the paper base layer are coated with waterproof adhesive, and the top and bottom of the paper base layer are respectively connected to the first waterproof layer and the second waterproof layer by the waterproof adhesive.

[0009] By adopting the above technical solution, the combination of waterproof adhesive, first waterproof layer and second waterproof layer can achieve waterproofing and prevent food packaging paper from being soaked by water.

[0010] Preferably, the top of the first waterproof layer is coated with a first oil-resistant adhesive, and the first waterproof layer is connected to the nylon mesh and the degradation layer through the first oil-resistant adhesive.

[0011] By adopting the above technical solution, the nylon mesh is composed of degradable materials, and the nylon mesh and the degradable layer are covered on the surface of the first waterproof layer by the first oil-resistant adhesive.

[0012] Preferably, the bottom of the second waterproof layer is coated with a second oil-resistant adhesive, and the bottom of the second waterproof layer is connected to the reinforcing layer through the second oil-resistant adhesive.

[0013] By adopting the above technical solution, the first and second oil-resistant adhesives work together to prevent oil from wetting the food packaging paper.

[0014] Preferably, the degradable layer fills the gaps in the nylon mesh, and the paper base layer, the first waterproof layer, the second waterproof layer, the reinforcing layer, the oil-proof layer, and the printing layer are all made of degradable materials.

[0015] By adopting the above technical solutions, the paper base layer, the first waterproof layer, the second waterproof layer, the reinforcing layer, the oil-proof layer, the degradable layer, and the printing layer can be rapidly degraded, enabling food packaging paper to degrade quickly.

[0016] Preferably, the oil-resistant layer is a fluorocarbon-free waterproof and oil-resistant latex.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: After the food packaging paper has been used, due to the creases on the food packaging paper, the user can tear along the creases to expose the nylon mesh inside the food packaging paper. Then, pulling the nylon mesh can cut the food packaging paper, thereby destroying the oil-proof layer. This breaks down the overall structure of the paper base layer, the first waterproof layer, the second waterproof layer, the reinforcing layer, and the oil-proof layer, allowing it to fully contact the outside world and improving the degradation rate of the food packaging paper. Furthermore, the food packaging paper is provided with waterproof adhesive, first oil-proof adhesive, second oil-proof adhesive, and an oil-proof layer, which prevents the food packaging paper from being soaked by oil or water. The nylon mesh also facilitates the separation of the printing layer and the food packaging paper, making the degradation of the food packaging paper easier. Attached Figure Description

The nylon mesh 108 and the degradation layer 109 are covered on the surface of the first waterproof layer 102 through the first oil-resistant adhesive 104.

[0026] In this embodiment, the bottom of the second waterproof layer 103 is coated with a second oil-resistant adhesive 105. The bottom of the second waterproof layer 103 is connected to the reinforcing layer 106 through the second oil-resistant adhesive 105. The first oil-resistant adhesive 104 and the second oil-resistant adhesive 105 work together to prevent oil from wetting the food packaging paper.

[0027] In this embodiment, the degradable layer 109 fills the gaps in the nylon mesh 108.
