隨著外賣行業的蓬勃發展，一次性外賣打包盒已成為餐飲商戶的日常剛需。面對市場上琳瑯滿目的產品，如何科學選型、平衡成本與質量，成為批量采購時的核心課題。本文將從材質特性、功能需求、成本控制及環保合規四個維度，為商戶提供系統性選購建議。

　　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.

　　材質選擇：安全與場景的雙重考量

　　Material selection: dual considerations of safety and scene

　　目前主流打包盒材質包括聚丙烯（PP）、聚苯乙烯（PS）、紙漿模塑及可降解材料。PP材質耐高溫（可承受120℃以上），適用于熱食類外賣，如炒飯、湯面，其密封性較好，但成本相對較高；PS材質透明度高、成本低廉，常用于冷餐或低溫食品，如沙拉、壽司，但遇熱易變形，需避免盛裝熱食；紙漿模塑材質環保可降解，適合輕食類包裝，但防油性較弱，需配合淋膜工藝使用；可降解材料如PLA（聚乳酸）雖環保，但耐溫性有限（約60℃），需根據菜品特性選擇。

　　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.

　　容量與尺寸：精準匹配菜品特性

　　Capacity and size: Accurately match dish characteristics

　　外賣打包盒的容量需與菜品分量嚴格對應。常見容量規格包括500ml（單人簡餐）、750ml（蓋澆飯）、1000ml（湯面類）及1500ml（多人份套餐）。選購時應測試實際裝載量，例如湯面類需預留膨脹空間，避免配送過程中溢出；帶湯汁菜品需選擇帶凹槽設計的盒型，防止湯汁外漏。此外，盒體高度與直徑比例需適配菜品形態，如炒菜類宜選淺而寬的盒型，便于取食；燉煮類則需深盒保持溫度。

　　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：防漏設計的關鍵細節

　　Sealing performance: key details of leak proof design

　　密封性直接影響顧客體驗。卡扣式盒蓋通過凸起卡扣與盒體咬合，適合固體類食物，但反復開合易松動；覆膜式盒蓋采用熱封工藝，密封性好，但需專用設備操作；折疊式盒蓋通過側邊鎖扣固定，適合湯汁類菜品，但成本較高。測試時可裝入等量水傾斜15分鐘，觀察滲漏情況。

　　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：從批量采購到使用優化

　　Cost control: from bulk procurement to usage optimization

　　批量采購時，可與供應商協商階梯定價，通常單次采購量超1萬只可獲5%-10%折扣。材質選擇上，PP材質雖單價高，但重復使用率高，長期成本可能低于頻繁更換的PS材質。此外，優化盒型設計可減少耗材，如選擇帶分隔的盒型替代多個獨立包裝，既降低成本又提升顧客體驗。

　　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.

　　環保合規：政策與市場的雙重驅動

　　Environmental Compliance: Dual Drivers of Policy and Market

　　隨著“限塑令”升級，可降解材料成為趨勢。選購時需確認產品是否通過“雙J認證”（可降解認證）及“食品接觸安全認證”。紙漿模塑盒需檢查淋膜層是否為PLA或水性涂層，避免傳統PE淋膜影響降解。

　　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.

　　供應商篩選：資質與服務的綜合評估

　　Supplier screening: comprehensive evaluation of qualifications and services

　　選擇供應商時，需核查其生產許可證、檢測報告（重點查看總遷移量、重金屬等指標）及環保認證。

　　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.
