Problems solved by technology

Photodegradable plastics contain photosensitizers, which achieve the purpose of degradation by absorbing ultraviolet rays. The disadvantages are high cost, and it is not easy to control the degradation rate. Buried underground still cannot be completely degraded, which brings harm to environmental soil and groundwater; most of biodegradable plastics Containing starch, its products can be decomposed by microorganisms within a certain period of time to achieve the purpose of degradation after being discarded. The disadvantage is that its mechanical properties are reduced, which affects its scope of use.
Therefore, there is no environmentally friendly plastic lunch box that can be completely and effectively degraded on the market.

Abstract

A novel environmental friendly plastic lunch box is provided. The plastic lunch box is prepared from a fully biodegradable material. The main component of the fully biodegradable material is a polymaltotriose polymer compound. The lunch box also comprises a handle 1, fixing clamps 2, a first-layer lunch box 3, a second-layer lunch box 4 and a vent hole 5. The first-layer lunch box and the second-layer lunch box can be used separately. The fixing clamps are used for fixing the first-layer lunch box and the second-layer lunch box respectively. The vent hole is in the top surface of the first-layer lunch box. The plastic lunch box is novel in material, simple in structure and easy to manufacture and use and brings a lot of convenience to human life and the environment.

Description

technical field [0001] The invention relates to a lunch box, in particular to a novel environment-friendly plastic lunch box. Background technique [0002] Lunch boxes are indispensable daily necessities in people's daily life. At present, most of the lunch boxes on the market are made of plastic. With the development of the plastic industry, there are more and more plastic products, and at the same time, the plastic waste is also increasing, and the phenomenon of "white garbage" in cities is becoming more and more serious. At present, the treatment methods for plastic waste mainly include: 1) Landfill, recycling, and incineration. This method needs a large amount of manpower and material resources, is slow and difficult to carry out, and also produces toxic gases during incineration, causing secondary pollution to the environment. 2) Research on degradable plastics. Degradable plastics mainly include photodegradable and biodegradable. Photodegradable plastics contain ph...
