Description

Technical Field

[0001] The utility model relates to the technical field of lunch boxes, in particular to a degradable lunch box with good heat insulation effect. Background Art

[0002] Degradable lunch boxes refer to lunch boxes that can be degraded into carbon dioxide and water through biochemical reactions under the action of natural microorganisms (such as bacteria, molds, algae) and enzymes. The degradation process of this type of lunch box does not require human participation and has little impact on the environment. The materials of degradable lunch boxes are mainly divided into two categories: New stone lunch boxes: made of new stone such as paper products, straw, starch, etc., this type of lunch box is fully degradable and is also called environmentally friendly products. For example, corn starch-based lunch boxes are one of the more common degradable lunch boxes on the market. They use natural corn starch and plant fibers as the base material, supplemented by bio-polyester, polyols and other materials. It has the advantages of being degradable, strong, non-leakage, odorless, temperature-resistant and grease-resistant; Plastic-based lunch boxes: made of plastic as the main component, with starch, photosensitizer and other substances added. Although this type of lunch box has the characteristics of being degradable, it may face some problems during the degradation process, such as uncertain degradation time, poor tolerance and difficulty in recycling;

[0003] Degradable lunch boxes usually use natural plant fibers, starch-based materials, etc. as raw materials. The thermal conductivity of these materials is relatively poor, but their own thermal insulation performance is not high. Compared with special thermal insulation materials, they are insufficient in preventing heat transfer. Most degradable lunch boxes do not particularly emphasize thermal insulation performance when designing. Their structure is often relatively simple, and there is no special thermal insulation layer or thermal insulation design. This causes the heat to be easily and quickly conducted to the outside through the wall of the lunch box when high-temperature food is placed in the lunch box, affecting the thermal insulation effect. In the process of producing degradable lunch boxes, in order to reduce costs and improve production efficiency, thinner raw materials or simpler production processes may be used. These factors may affect the thermal insulation performance of the lunch box, causing it to perform poorly in actual use. Therefore, the utility model proposes a degradable lunch box with good thermal insulation effect to solve the problems existing in the prior art. Utility Model Content
