选择可降解的一次性外卖打包盒是一项重要的决策，它不仅关系到环境保护，还涉及到食品的安全和质量。以下是一些选择可降解一次性外卖打包盒的要点：

　　Choosing biodegradable disposable takeaway packaging boxes is an important decision that not only concerns environmental protection, but also involves food safety and quality. Here are some key points for choosing biodegradable disposable takeaway packaging boxes:

　　一、考虑材料的可降解性

　　1、 Consider the degradability of materials

　　纸质材料：纸质餐盒是一种常见的可降解外卖打包盒材料。我国的外卖包装经历了发泡餐盒 ——PP 塑料餐具 —— 可降解纸质餐盒三个阶段。纸质餐盒具有一定的强度，可以承受食物的重量，同时在自然环境中相对容易降解。例如，上海市发布和实施的 T/31SAFCM004-2018《餐饮服务 (网络) 外卖 (外带) 用纸碗通用技术要求》旨在推动消费市场使用可降解外卖纸碗替代外卖塑料送餐盒，减少塑料送餐盒和包装材料产生的环境污染。

　　Paper material: Paper meal boxes are a common biodegradable food delivery packaging material. Our country's food delivery packaging has gone through three stages: foam meal boxes, PP plastic tableware, and biodegradable paper meal boxes. Paper meal boxes have a certain strength, can withstand the weight of food, and are relatively easy to degrade in natural environments. For example, the T/31SAFCM004-2018 "General Technical Requirements for Food and Beverage Service (Online) Takeout (Takeout) Paper Bowls" released and implemented by Shanghai aims to promote the use of biodegradable takeaway paper bowls instead of plastic delivery boxes in the consumer market, reducing environmental pollution caused by plastic delivery boxes and packaging materials.

　　植物纤维材料：一些外卖打包盒采用植物纤维制成，如以植物叶子为原料的全食品可降解餐盒。这种餐盒纯自然无污染，通过与落叶回收站合作，可以获得充足的高质量原材料，取之于自然，同时回归自然。

　　Plant fiber materials: Some takeaway packaging boxes are made of plant fibers, such as whole food biodegradable meal boxes made from plant leaves. This type of food box is pure natural and pollution-free. By cooperating with a leaf litter recycling station, we can obtain sufficient high-quality raw materials, take them from nature, and return to nature at the same time.

　　生物降解塑料：生物降解塑料是一种在特定环境下可以被微生物分解的塑料。例如，从虾壳中提取的可降解生物聚合物材料壳聚糖，具有生物相容性、生物降解性、无毒等优点，可用于制作薄膜。

　　Biodegradable plastics: Biodegradable plastics are plastics that can be decomposed by microorganisms in specific environments. For example, chitosan, a biodegradable biopolymer material extracted from shrimp shells, has advantages such as biocompatibility, biodegradability, and non toxicity, and can be used to make thin films.

　　二、关注食品安全性

　　2、 Pay attention to food safety

　　卫生标准：选择符合国家卫生标准的外卖打包盒至关重要。可降解餐盒应在生产过程中严格控制卫生条件，避免有害物质的残留。例如，采用 CBL-ZF80/65 双层复合挤出吸塑成型机制备的覆膜一次性快餐盒，按照国标 GB18006.1-2009 检测其卫生理化性能，结果表明覆膜快餐盒在重金属含量、脱色试验等方面表现良好。

　　Hygiene standards: It is crucial to choose takeaway packaging boxes that meet national hygiene standards. Biodegradable food containers should strictly control hygiene conditions during the production process to avoid the residue of harmful substances. For example, the laminated disposable fast food box prepared by the CBL-ZF80/65 double-layer composite extrusion and vacuum forming mechanism was tested for its hygiene and physicochemical properties according to the national standard GB18006.1-2009. The results showed that the laminated fast food box performed well in heavy metal content, decolorization test, and other aspects.

　　隔离性能：外卖打包盒应具有良好的隔离性能，防止食物与外界环境相互影响。可降解材料在保证隔离性能的同时，也要确保不会对食物的味道和质量产生不良影响。

　　Isolation performance: Takeout packaging boxes should have good isolation performance to prevent food from interacting with the external environment. Degradable materials should not only ensure isolation performance, but also ensure that they do not have adverse effects on the taste and quality of food.

　　三、评估包装的实用性

　　3、 Evaluate the practicality of packaging

　　强度和耐用性：尽管是一次性使用，但外卖打包盒也需要有足够的强度来承受食物的重量和运输过程中的压力。纸质餐盒在这方面可能需要通过特殊的设计和加工来提高强度。

　　Strength and durability: Although disposable, takeaway packaging boxes also need sufficient strength to withstand the weight of food and the pressure during transportation. Paper meal boxes may require special design and processing to enhance their strength in this regard.

　　密封性：良好的密封性可以防止食物泄漏和外界异味的进入。可降解材料的密封性可能需要通过特殊的密封设计或添加密封材料来实现。

　　Sealing: Good sealing can prevent food leakage and the entry of external odors. The sealing performance of biodegradable materials may require special sealing designs or the addition of sealing materials.

　　尺寸和形状：根据不同的食物类型和外卖订单需求，选择合适尺寸和形状的外卖打包盒。例如，对于液体食物，需要选择具有良好密封性和防漏性能的容器；对于固体食物，可以选择更加方便堆叠和运输的形状。

　　Size and shape: Choose the appropriate size and shape of takeaway packaging box according to different food types and takeaway order requirements. For example, for liquid food, it is necessary to choose containers with good sealing and leak proof properties; For solid foods, you can choose shapes that are more convenient for stacking and transportation.

　　四、考虑成本因素

　　4、 Consider cost factors

　　价格：可降解外卖打包盒的价格可能会比传统塑料餐盒略高。在选择时，需要综合考虑成本和环保效益。一些可降解材料的成本可能会随着技术的进步和市场需求的增加而逐渐降低。

　　Price: The price of biodegradable takeaway packaging boxes may be slightly higher than traditional plastic meal boxes. When making a choice, it is necessary to consider both cost and environmental benefits comprehensively. The cost of some biodegradable materials may gradually decrease with technological advancements and increasing market demand.

　　可持续性成本：除了直接的购买成本，还需要考虑可持续性成本。例如，使用可降解餐盒可能会减少对环境的污染，降低后期的处理成本。同时，一些可降解材料可以通过回收和再利用来降低成本。

　　Sustainability costs: In addition to direct purchase costs, sustainability costs also need to be considered. For example, using biodegradable meal boxes may reduce environmental pollution and lower later processing costs. Meanwhile, some biodegradable materials can be recycled and reused to reduce costs.
