Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0025] Please refer to Figures 1-5 The present application is a non-plastic degradable film covering type environmental protection paper cup, which comprises a paper cup body 1, a cup pad 2 is fixedly connected to the bottom of the paper cup body 1, an environmental protection assembly 3 is arranged on the inner wall of the paper cup body 1, the environmental protection assembly 3 comprises a paper layer 31, the paper layer 31 is arranged on the inner wall of the paper cup body 1, a non-plastic degradable film layer 32 is arranged below the paper layer 31, a coating layer 33 is arranged below the non-plastic degradable film layer 32, an outer decorative layer 34 is arranged below the coating layer 33, and the non-plastic degradable film layer 32, the coating layer 33 and the outer decorative layer 34 are all arranged on the inner wall of the paper cup body 1.
[0026] The paper layer 31 is located between the paper cup body 1 and the plastic-free degradable film layer 32, and the inside of the paper layer 31 comprises food-grade pulp, wood pulp paper. The paper layer 31 is usually made of food-grade wood pulp paper or recycled paper. The wood pulp paper has good toughness, strength and applicability, and can provide structural support for the paper cup.
[0027] The plastic-free degradable film layer 32 is located between the paper layer 31 and the coating layer 33, and the inside of the plastic-free degradable film layer 32 comprises polylactic acid. The main function of this layer of film is to provide waterproof and oil-proof functions, so that the inside of the paper cup does not leak liquid.
[0028] The coating layer 33 is located between the plastic-free degradable film layer 32 and the outer decorative layer 34, and the inside of the coating layer 33 comprises a plant-based starch layer. This coating layer 33 further enhances the waterproofness and oil-proofness of the paper cup body 1, so that the paper cup body 1 can contain oily.
[0029] The outer decorative layer 34 is located between the coating layer 33 and the paper cup body 1, and the inside of the outer decorative layer 34 is degradable water-based ink. The outer decorative layer 34 plays a role in aesthetics, brand display and consumer information transmission.
[0030] The soft ring 4 is fixedly connected to the end of the paper cup body 1 away from the cup pad 2. The soft ring 4 is made of food-grade pulp material. The soft ring 4 is located at the top of the paper cup body 1, which is convenient for users to drink water.
[0031] The cup sleeve 5 is fixedly sleeved on the circumferential surface of the paper cup body 1. The cup sleeve 5 is made of wood pulp paper. The design of the cup sleeve 5 is convenient for users to hold when the cup contains hot water, preventing the user from being scalded.

The non-plastic degradable film layer 32 contains PLA polylactic acid inside, mainly provides waterproof and oil-proof functions, so that the paper cup does not leak liquid inside, keeps the cup from losing structural strength due to wetness. Compared with traditional plastic film (such as polyethylene PE film), the PLA polylactic acid film has better environmental friendliness because it can be decomposed into carbon dioxide and water in an industrial composting environment, improving the efficiency of recycling. The coating layer 33 further enhances the waterproofness and oil-proofness of the paper cup, so that the paper cup can contain oily, acidic or high-temperature liquid without being prone to leakage. It can also provide better food contact safety, meeting relevant safety standards for food packaging. The outer decorative layer 34 is used to print patterns, brand information or decorative levels, which is usually not directly in contact with liquid, mainly plays the role of aesthetics, brand display and consumer information transmission, and enhances the decorative nature of the paper cup. Through the environmental protection assembly 3, the environmental protection is improved, the use of plastic is reduced, the degradable material is used, the environmental protection requirement is met, the food-grade material is used to ensure the safety of the paper cup, and the durability and functionality are enhanced. Even if the plastic film is not used, the paper cup can still have waterproof and oil-proof functions and can bear high temperature and liquid, has a certain degradability, and the material such as PLA polylactic acid can be biodegraded under appropriate composting conditions, without causing long-term pollution to the environment.
