Description

Technical Field

[0001] The utility model relates to the technical field of packaging paper, in particular to a food anti-sticking packaging paper. Background Art

[0002] Food wrapping paper is primarily made from pulp and paperboard. It must be non-toxic, oil-resistant, waterproof, moisture-proof, and airtight, and meet food packaging safety requirements. Because food wrapping paper comes into direct contact with food, and most of the packaging is for food that is eaten directly, the most fundamental requirement for food wrapping paper is that it must comply with food hygiene requirements. Furthermore, depending on the specific application requirements, it must also meet relevant technical standards.

[0003] However, in the prior art, the anti-sticking effect of food packaging paper is poor, and food is easily stuck to the packaging paper, which easily damages the appearance of the food or makes it impossible to completely remove the food. Therefore, the utility model provides a food anti-sticking packaging paper. Utility Model Content

[0004] The purpose of the utility model is to provide a food anti-stick packaging paper, which can effectively prevent the food from sticking to the packaging paper through the anti-stick coating, prevent the food from being damaged or unable to be completely removed, and improve applicability; the isolation layer can effectively prevent moisture penetration or grease leakage of the food, keeping the packaging clean and stable; and the breathable layer can improve air circulation, preventing the food from deteriorating due to moisture accumulation.

[0005] In order to achieve the above-mentioned purpose of the utility model, the technical solution provided by the utility model is: a food anti-stick packaging paper, including a paper main body, a paper base layer is provided in the middle of the paper main body, the top surface of the paper base layer is adhered with an anti-stick coating, the bottom surface of the paper base layer is adhered with an isolation layer, and the bottom surface of the isolation layer is adhered with a breathable layer.

[0006] Furthermore, the anti-stick coating is a natural vegetable oil coating, and the natural vegetable oil includes but is not limited to soybean oil, corn oil or olive oil.

[0007] Furthermore, the isolation layer is a polyethylene film.

[0008] Furthermore, the breathable layer is a microporous polyester film.

[0009] Furthermore, the paper base layer is high-quality food-grade paper.

[0010] Compared with the prior art, the advantages of the present invention are as follows: the anti-stick coating can effectively prevent the food from sticking to the packaging paper, effectively preventing the appearance of the food from being damaged or unable to be completely removed, thereby improving applicability; the isolation layer can effectively prevent moisture penetration or grease leakage from the food, thereby keeping the packaging clean and stable; and the breathable layer can improve air circulation, thereby preventing the food from spoiling due to moisture accumulation.

[0014] To facilitate a clear understanding of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0015] Combined with attachment Figure 1 To the attached Figure 2 A food anti-stick packaging paper includes a paper body 1, a paper base layer 2 is provided in the middle of the paper body 1, the top surface of the paper base layer 2 is adhered with an anti-stick coating 3, the bottom surface of the paper base layer 2 is adhered with an isolation layer 4, and the bottom surface of the isolation layer 4 is adhered with a breathable layer 5.

[0016] Furthermore, the anti-stick coating 3 is a natural vegetable oil coating, and the natural vegetable oil includes but is not limited to soybean oil, corn oil or olive oil, which can ensure that the packaging paper does not adhere to the surface of the food, thereby maintaining the cleanliness of the packaging and the integrity of the food.

[0017] The further isolation layer 4 is a polyethylene film, which is mainly used to block the grease and moisture of the food, preventing the packaging paper from being damaged by grease or moisture, thereby maintaining the strength and structural integrity of the packaging paper, and helping to prevent grease from penetrating into the packaging paper and affecting the quality of the food.

[0018] Furthermore, the breathable layer 5 is a microporous polyester film with excellent gas exchange capacity, ensuring that the wrapping paper has appropriate breathability to prevent the food from becoming moldy or deteriorating due to moisture accumulation in the package. This layer helps to keep the food dry and extend its shelf life.

[0019] Furthermore, the paper base layer 2 is high-quality food-grade paper, which provides structural support and mechanical strength, so that the packaging paper has appropriate rigidity and durability.

[0020] Specific implementation methods of the present invention: The anti-stick coating 3 can ensure that the packaging paper and the food surface do not adhere to each other, thereby maintaining the cleanliness of the packaging and the integrity of the food; the isolation layer 4 can block the grease and moisture of the food, preventing the packaging paper from being damaged by grease or moisture, thereby maintaining the strength and structural integrity of the packaging paper; the breathable layer 5 ensures that the packaging paper has appropriate air permeability, thereby preventing the food from becoming moldy or deteriorating due to moisture accumulation in the packaging.

[0021] The above description is only a preferred embodiment of the present utility model patent and is not intended to limit the present utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model patent shall be included in the scope of protection of the present utility model patent.
