一、塑料类打包盒​

1、 Plastic packaging box

塑料类打包盒是目前市场上使用最广泛的类型之一，常见的材质有聚丙烯（PP）、聚苯乙烯（PS）等。PP 材质的打包盒具有良好的耐热性，可在微波炉中加热，且化学稳定性较好，不易与食物发生反应。其优点是成本较低、透明度高、密封性强，能够清晰看到盒内食物，同时有效防止汤汁渗漏。但它也存在明显的缺点，塑料难以自然降解，丢弃后会在环境中留存数百年，造成严重的白色污染。此外，一些劣质塑料打包盒在高温下可能会释放出有害物质，威胁人体健康。​

Plastic packaging boxes are currently one of the most widely used types in the market, with common materials such as polypropylene (PP) and polystyrene (PS). PP material packaging boxes have good heat resistance, can be heated in microwave ovens, and have good chemical stability, making them less likely to react with food. Its advantages are low cost, high transparency, strong sealing, and the ability to clearly see the food inside the box, while effectively preventing soup leakage. But it also has obvious drawbacks, plastic is difficult to naturally degrade, and after being discarded, it will remain in the environment for hundreds of years, causing serious white pollution. In addition, some inferior plastic packaging boxes may release harmful substances at high temperatures, posing a threat to human health. ​

PS 材质的打包盒质地硬且脆，常用于制作一次性碗、杯等。它价格低廉，成型容易，但不耐高温，不能用于盛装热食，且同样面临难以降解的环保难题。​

The packaging box made of PS material is hard and brittle, commonly used for making disposable bowls, cups, etc. It is inexpensive and easy to shape, but it is not resistant to high temperatures and cannot be used to hold hot food. It also faces environmental challenges such as difficulty in degradation. ​

二、纸质类打包盒​

2、 Paper packaging box

纸质类打包盒以天然植物纤维为原料，如木浆、竹浆等。这类打包盒最大的优势在于环保性较好，可回收利用，且在自然环境中能够较快降解。同时，其表面可以进行精美的印刷，提升外卖的品牌形象。不过，纸质打包盒也有局限性。由于纸张本身的特性，它的防水、防油性能相对较弱，盛装含汤汁较多或油脂丰富的食物时，容易出现渗漏、变形的情况。而且，为了增强防水防油效果，部分纸质打包盒会在表面添加化学涂层，若处理不当，这些涂层中的化学物质可能会迁移到食物中，带来健康风险。​

Paper packaging boxes are made from natural plant fibers such as wood pulp, bamboo pulp, etc. The biggest advantage of this type of packaging box is its good environmental friendliness, recyclability, and ability to degrade quickly in natural environments. At the same time, its surface can be beautifully printed to enhance the brand image of food delivery. However, paper packaging boxes also have limitations. Due to the inherent characteristics of paper, its waterproof and oil resistant properties are relatively weak. When storing food with a lot of soup or rich oil, it is prone to leakage and deformation. Moreover, in order to enhance the waterproof and oil resistant effect, some paper packaging boxes will have chemical coatings added to the surface. If not handled properly, the chemicals in these coatings may migrate to food, posing health risks. ​

三、生物可降解类打包盒​

3、 Biodegradable packaging box

生物可降解类打包盒是近年来兴起的新型环保包装材料，主要由玉米淀粉、聚乳酸（PLA）等可生物降解材料制成。它们在自然环境中，可通过微生物的作用分解为二氧化碳和水，不会对环境造成长期污染。这类打包盒在性能上与传统塑料打包盒相似，具有良好的密封性、耐热性和机械强度，能够满足外卖包装的基本需求。然而，目前生物可降解类打包盒也面临一些问题，一方面其生产成本相对较高，导致售价较贵，限制了在市场上的广泛推广；另一方面，生物可降解材料的降解需要特定的环境条件，如合适的温度、湿度和微生物环境，若处理不当，在普通垃圾填埋场中也难以实现快速降解。​

Biodegradable packaging boxes are a new type of environmentally friendly packaging material that has emerged in recent years, mainly made of biodegradable materials such as corn starch and polylactic acid (PLA). They can be decomposed into carbon dioxide and water through the action of microorganisms in the natural environment, without causing long-term pollution to the environment. This type of packaging box is similar in performance to traditional plastic packaging boxes, with good sealing, heat resistance, and mechanical strength, which can meet the basic needs of takeaway packaging. However, currently biodegradable packaging boxes also face some problems. On the one hand, their production costs are relatively high, resulting in expensive prices and limiting their widespread promotion in the market; On the other hand, the degradation of biodegradable materials requires specific environmental conditions, such as appropriate temperature, humidity, and microbial environment. If not handled properly, it is also difficult to achieve rapid degradation in ordinary landfills. ​
