Technical Field
[0001] The utility model relates to the technical field of tableware, and in particular discloses a lunch box which is convenient for separation and garbage classification. Background Art
[0002] With the continuous development of the takeaway industry and the increasing awareness of environmental protection, people have higher and higher requirements for disposable tableware. Disposable tableware made of biodegradable plastic filled with bamboo powder has become a trend. Biodegradable tableware refers to tableware that can undergo biochemical reactions under the action of microorganisms (bacteria, mold, algae) and enzymes in the natural environment, causing the appearance to become moldy and the internal quality to change, and finally forming carbon dioxide and water. Biodegradable plastic filled with bamboo powder, also known as biodegradable bamboo plastic material, has been widely used in the food packaging industry.
[0003] In the existing technical solutions, in order to prevent water and oil from seeping out of the lunch box, a layer of PP film is pasted inside the lunch box. Since the PP film needs to be decomposed at high temperature (greater than 280°C) or under ultraviolet irradiation, the lunch box cannot be decomposed in time, which is not convenient for garbage classification and affects the recycling of the lunch box. At the same time, the used lunch boxes have food residues and oil stains, which affects the recycling value of the lunch boxes. It is necessary to study a new type of lunch box to maximize the avoidance of non-degradable plastic lunch boxes from being landfilled, abandoned or incinerated, so as to achieve the goal of emission reduction in both economy and environmental protection.
