Description

Technical Field

[0001] This utility model relates to the field of coated paper technology, and in particular to an anti-slip biodegradable coated paper. Background Technology

[0002] Laminated paper, with its oil- and water-resistant properties, is widely used in food packaging, disposable daily necessities trays, and express delivery cushioning. However, with increasingly stringent global environmental policies and rising market demand for green packaging, traditional laminated paper using PE (polyethylene) as the lamination layer is becoming increasingly incompatible with environmental protection needs. This is because it is difficult to biodegrade naturally and tends to remain in the environment for extended periods after disposal, causing white pollution. Furthermore, in scenarios such as food tray support and tableware placement, the smooth surface of traditional laminated paper lacks sufficient anti-slip properties, easily causing items to slip, shift, or even fall and become damaged, affecting safety and user experience. Some laminated papers also have only a single-layer lamination structure, resulting in poor strength and toughness, making them prone to tearing and breakage during use. In addition, the PE layer of traditional laminated paper is tightly bonded to the base paper, making it difficult to separate. Even if the base paper has recycling value, the presence of the lamination layer prevents effective recycling and reuse, leading to resource waste. These problems hinder further improvements in the environmental friendliness, practicality, and resource utilization of laminated paper. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a non-slip biodegradable coated paper that can enhance the strength and toughness of the coated paper, increase surface friction, improve the non-slip performance of the coated paper, and allow the outer first and second coated layers of the unused coated paper to be manually peeled off for separate composting and recycling of the base paper.

[0004] This utility model also provides a non-slip biodegradable coated paper, comprising a base paper, two starch adhesive layers fixedly connected to the outer wall of the base paper, a first coated layer fixedly connected to the outer wall of the starch adhesive layer, and a second coated layer fixedly connected to the outer wall of the first coated layer.

[0005] According to the present invention, an anti-slip biodegradable coated paper is provided, wherein the base paper, starch adhesive layer, first coated layer and second coated layer are fixedly connected at both ends with sealing edges.

[0006] According to the present invention, a non-slip biodegradable coated paper has multiple honeycomb grooves fixedly connected to the inner wall of the first coated layer.

[0007] According to the present invention, a non-slip biodegradable coated paper has multiple micro-protrusions uniformly and equidistantly fixedly connected to the outer wall of the second coated layer.

[0008] Beneficial effects:

[0009] 1. The first coating layer and the second coating layer are set on the outside of the base paper. The inner wall of the first coating layer has honeycomb holes, which can enhance the strength and toughness of the coated paper. The outer wall of the second coating layer has multiple micro protrusions evenly distributed at equal intervals, which can increase the surface friction and improve the anti-slip performance of the coated paper.

[0010] 2. By using PLA (polylactic acid) material, a biodegradable material, instead of PE (polyethylene), the coated paper becomes biodegradable. The first and second coated layers are connected to the base paper through a starch adhesive layer. Unused coated paper can be manually peeled off the outer first and second coated layers for separate composting, and the base paper can be recycled. Attached Figure Description

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4 This utility model provides an anti-slip biodegradable coated paper, which includes a base paper 1, two starch adhesive layers 4 fixedly connected to the outer wall of the base paper 1, a first coated layer 5 fixedly connected to the outer wall of the starch adhesive layer 4, and a second coated layer 6 fixedly connected to the outer wall of the first coated layer 5.

[0020] Specifically, the starch adhesive layer 4 is mainly composed of starch, combined with some auxiliary agents such as glycerin and plant gum, which can bond the base paper 1 to the outer first coating layer 5 and the second coating layer 6. When needed, the outer first coating layer 5 and the second coating layer 6 can be manually peeled off directly for easy recycling.

[0021] The base paper 1, starch adhesive layer 4, first coating layer 5, and second coating layer 6 are fixedly connected at both ends with edge sealing 2.

[0022] Specifically, the base paper 1, starch adhesive layer 4, first coating layer 5, and second coating layer 6 are fixed together by the sealing edge 2, which is fixedly connected at both ends, to ensure the overall performance and appearance of the coated paper.

[0023] The inner wall of the first coating layer 5 is fixedly connected with multiple honeycomb grooves 7.

[0024] Specifically, the inner wall of the first coating layer 5 is fixed with multiple honeycomb grooves 7. The honeycomb structure can buffer and absorb kinetic energy, and enhance the internal strength and toughness of the paper.

[0025] The outer wall of the second coating layer 6 is uniformly and equidistantly fixed with multiple micro protrusions 3.

[0026] Specifically, the outer wall of the second coating layer 6 has multiple micro-protrusions 3 evenly distributed, which can enhance the surface friction of the coated paper and enhance its anti-slip ability.

[0027] Working principle: The starch adhesive layer 4 set at both ends of the base paper 1 allows the base paper 1 to be separated from the outer first coating layer 5 and second coating layer 6. The starch adhesive layer 4 is mainly composed of starch and biodegradable materials such as glycerin and plant gum. The outer first coating layer 5 and second coating layer 6 can be manually peeled off the unused coated paper, thereby realizing the recycling of the base paper 1. The peeled part can also be used for composting. The inner wall of the first coating layer 5 outside the starch adhesive layer 4 has multiple honeycomb grooves 7. The honeycomb structure can buffer and absorb energy, providing strength and toughness to the coated paper. The outermost second coating layer 6 has multiple micro protrusions 3 evenly distributed on its outer wall. The micro protrusions 3 enhance the surface friction of the second coating layer 6, thereby improving the anti-slip ability of the coated paper.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
