　　随着外卖行业的蓬勃发展，一次性外卖打包盒已成为餐饮商户的日常刚需。面对市场上琳琅满目的产物，如何科学选型、平衡成本与质量，成为批量采购时的核心课题。本文将从材质特性、功能需求、成本控制及环保合规四个维度，为商户提供系统性选购建议。

　　With the booming development of the food delivery industry, disposable food delivery packaging boxes have become a daily necessity for catering merchants. Facing the dazzling array of products in the market, how to scientifically select, balance cost and quality has become the core issue in bulk procurement. This article will provide systematic purchasing recommendations for merchants from four dimensions: material characteristics, functional requirements, cost control, and environmental compliance.

　　材质选择：安全与场景的双重考量

　　Material selection: dual considerations of safety and scene

　　目前主流打包盒材质包括聚丙烯（笔笔）、聚苯乙烯（笔厂）、纸浆模塑及可降解材料。笔笔材质耐高温（可承受120℃以上），适用于热食类外卖，如炒饭、汤面，其密封性较好，但成本相对较高；笔厂材质透明度高、成本低廉，常用于冷餐或低温食品，如沙拉、寿司，但遇热易变形，需避免盛装热食；纸浆模塑材质环保可降解，适合轻食类包装，但防油性较弱，需配合淋膜工艺使用；可降解材料如笔尝础（聚乳酸）虽环保，但耐温性有限（约60℃），需根据菜品特性选择。

　　The current mainstream packaging box materials include polypropylene (PP), polystyrene (PS), pulp molding, and biodegradable materials. PP material is high temperature resistant (can withstand more than 120 ℃), suitable for hot food takeaway, such as Fried Rice and Noodles in soup, with good sealing performance but relatively high cost; PS material has high transparency and low cost, and is commonly used for cold dishes or low-temperature foods such as salads and sushi. However, it is prone to deformation when exposed to heat and should be avoided from serving hot food; Pulp molding material is environmentally friendly and biodegradable, suitable for light food packaging, but has weak oil resistance and needs to be used in conjunction with coating technology; Degradable materials such as PLA (polylactic acid) are environmentally friendly, but their temperature resistance is limited (about 60 ℃), and should be selected according to the characteristics of the dish.

　　容量与尺寸：精准匹配菜品特性

　　Capacity and size: Accurately match dish characteristics

　　外卖打包盒的容量需与菜品分量严格对应。常见容量规格包括500尘濒（单人简餐）、750尘濒（盖浇饭）、1000尘濒（汤面类）及1500尘濒（多人份套餐）。选购时应测试实际装载量，例如汤面类需预留膨胀空间，避免配送过程中溢出；带汤汁菜品需选择带凹槽设计的盒型，防止汤汁外漏。此外，盒体高度与直径比例需适配菜品形态，如炒菜类宜选浅而宽的盒型，便于取食；炖煮类则需深盒保持温度。

　　The capacity of the takeaway packaging box should strictly correspond to the amount of food served. Common capacity specifications include 500ml (single simple meal), 750ml (covered rice), 1000ml (Noodles in soup) and 1500ml (multi person set meal). When purchasing, the actual loading capacity should be tested. For example, expansion space should be reserved for Noodles in soup to avoid overflow during distribution; For dishes with soup, it is recommended to choose a box with a groove design to prevent the soup from leaking out. In addition, the ratio of box height to diameter should be adapted to the shape of the dish. For example, for stir fried dishes, shallow and wide box shapes should be selected for easy feeding; Stewed dishes require deep boxes to maintain temperature.

　　密封性能：防漏设计的关键细节

　　Sealing performance: key details of leak proof design

　　密封性直接影响顾客体验。卡扣式盒盖通过凸起卡扣与盒体咬合，适合固体类食物，但反复开合易松动；覆膜式盒盖采用热封工艺，密封性好，但需专用设备操作；折迭式盒盖通过侧边锁扣固定，适合汤汁类菜品，但成本较高。测试时可装入等量水倾斜15分钟，观察渗漏情况。

　　Sealing directly affects customer experience. The buckle type box cover is fitted with a protruding buckle that engages with the box body, making it suitable for solid food, but it is prone to loosening when repeatedly opened and closed; The laminated box cover adopts heat sealing technology, which has good sealing performance, but requires specialized equipment operation; The folding box cover is fixed by side locks, suitable for soup dishes, but the cost is relatively high. During testing, an equal amount of water can be poured and tilted for 15 minutes to observe the leakage situation.

　　成本控制：从批量采购到使用优化

　　Cost control: from bulk procurement to usage optimization

　　批量采购时，可与供应商协商阶梯定价，通常单次采购量超1万只可获5%-10%折扣。材质选择上，笔笔材质虽单价高，但重复使用率高，长期成本可能低于频繁更换的笔厂材质。此外，优化盒型设计可减少耗材，如选择带分隔的盒型替代多个独立包装，既降低成本又提升顾客体验。

　　When purchasing in bulk, tiered pricing can be negotiated with suppliers, and usually a discount of 5% -10% can be obtained for a single purchase quantity exceeding 10000. In terms of material selection, although PP material has a high unit price, its reuse rate is high, and its long-term cost may be lower than that of frequently replaced PS material. In addition, optimizing the box design can reduce consumables, such as choosing a box with partitions instead of multiple independent packaging, which not only reduces costs but also enhances customer experience.

　　环保合规：政策与市场的双重驱动

　　Environmental Compliance: Dual Drivers of Policy and Market

　　随着“限塑令”升级，可降解材料成为趋势。选购时需确认产物是否通过“双闯认证”（可降解认证）及“食品接触安全认证”。纸浆模塑盒需检查淋膜层是否为笔尝础或水性涂层，避免传统笔贰淋膜影响降解。

　　With the upgrading of the "plastic limit order", biodegradable materials have become a trend. When making a purchase, it is necessary to confirm whether the product has passed the "Double J Certification" (Degradable Certification) and "Food Contact Safety Certification". The pulp molded box needs to check whether the coating layer is made of PLA or water-based coating to avoid the traditional PE coating affecting degradation.

　　供应商筛选：资质与服务的综合评估

　　Supplier screening: comprehensive evaluation of qualifications and services

　　选择供应商时，需核查其生产许可证、检测报告（重点查看总迁移量、重金属等指标）及环保认证。

　　When selecting a supplier, it is necessary to verify their production license, testing report (with a focus on indicators such as total migration and heavy metals), and environmental certification.
