With the rapid development of the takeout ordering industry and the sharp increase in the demand for lunch boxes, the commonly used takeout boxes have developed from the previous polyethylene lunch boxes to the current PE lunch boxes. In order to save energy and environmental protection, paper lunch boxes are currently used in the market, but the current paper lunch boxes have poor thermal insulation performance, and because of the particularity of Chinese food, the dishes often contain oil and water and high outlet temperature, Therefore, the lunch boxes often become soft, deformed and leak oil, which is not conducive to the wide promotion and application of paper lunch boxes. In addition, the plastic lunch boxes are relatively firm, which is conducive to stacking and stacking during transportation.

由于現(xiàn)有的餐盒保溫性能以及抗壓強(qiáng)度有限，在對(duì)餐盒進(jìn)行堆碼時(shí)，易造成鼓肚、倒伏等問(wèn)題，無(wú)法滿足現(xiàn)在快節(jié)奏的外賣(mài)送餐餐盒的需求，以及滿足客戶(hù)日益增長(zhǎng)的產(chǎn)品需求，目前急需一種結(jié)構(gòu)新穎的紙質(zhì)餐盒來(lái)解決上述問(wèn)題以適應(yīng)如今迅猛發(fā)展的外賣(mài)打包需求。

Due to the limited thermal insulation performance and compressive strength of the existing lunch boxes, it is easy to cause problems such as belly bulging and lodging when stacking the lunch boxes, which can not meet the needs of the fast-paced takeout delivery lunch boxes and the growing product needs of customers, At present, a paper lunch box with novel structure is urgently needed to solve the above problems in order to meet the rapid development of takeout packaging demand.
