高品质一次性外卖打包盒需满足材质安全、物理性能达标、感官质量良好、符合卫生标准四大核心要求，具体分析如下：

　　High quality disposable takeaway packaging boxes need to meet four core requirements: material safety, physical performance standards, good sensory quality, and compliance with hygiene standards. The specific analysis is as follows:

　　一、材质安全：耐高温且无有害物质释放

　　1、 Material safety: high temperature resistance and no harmful substance release

　　推荐材质

　　Recommended materials

　　PP（聚丙烯，5号）：耐高温120℃以上，不含双酚A，长期使用稳定性强，是食品容器的理想选择。

　　PP (polypropylene, No. 5): resistant to high temperatures above 120 ℃, free of bisphenol A, and has strong long-term stability, making it an ideal choice for food containers.

　　Tritan（共聚酯，7号）：耐温90-100℃，完全不含双酚A，符合欧美母婴用品标准，安全性接近玻璃。

　　Tritan (copolyester, No. 7): resistant to temperatures of 90-100 ℃, completely free of bisphenol A, meets European and American standards for maternal and child products, and has safety close to glass.

　　PPSU（聚亚苯基砜树脂，7号）：医疗级材料，耐高温180℃，可反复高温消毒，是塑料杯中比较安全的材质之一。

　　PPSU (Polyphenylsulfone Resin, No. 7): Medical grade material, resistant to high temperatures up to 180 ℃, can be repeatedly sterilized at high temperatures, and is one of the safer materials for plastic cups.

　　需避开的材质

　　Materials to avoid

　　PS（聚苯乙烯，6号）：耐热性差（70℃以下），高温或长期使用可能析出有害物质，仅适合一次性或常温场景。

　　PS (polystyrene, No. 6): Poor heat resistance (below 70 ℃), may release harmful substances during high temperature or long-term use, only suitable for disposable or room temperature scenarios.

　　PET（聚对苯二甲酸乙二醇酯，1号）：同样耐热性不足，严禁装热水或重复使用。

　　PET (Polyethylene terephthalate, No. 1): Due to insufficient heat resistance, it is strictly prohibited to store hot water or reuse it.

　　含双酚A的PC材质：超过80℃易释放有害物质，国内婴幼儿产品已禁用，成人使用需确认“BPA Free”标识。

　　PC material containing bisphenol A: above 80 ℃, harmful substances are easily released. Domestic infant and toddler products have been banned, and adult use requires confirmation of the "BPA Free" label.

　　二、物理性能：负重与密封性达标

　　2、 Physical performance: Load bearing and sealing meet standards

　　负重性能

　　Load bearing performance

　　汤杯需承受一定重量（如盛装热汤）而不变形或破裂。部分企业为节省成本减少壁厚，导致负重性能不合格，产品较软，消费者难以拿捏，盛装热食时易烫伤。

　　The soup cup needs to withstand a certain weight (such as holding hot soup) without deformation or breakage. Some companies reduce wall thickness to save costs, resulting in poor load-bearing performance, soft products that are difficult for consumers to grasp, and easy burns when storing hot food.

　　检测方法：通过压力测试验证杯体在承受规定重量时的稳定性。

　　Testing method: Verify the stability of the cup body under specified weight through pressure testing.

　　密封性

　　sealing performance

　　防止汤汁泄漏是关键。密封性不合格的产品可能伴有漏水问题，使用中存在烫伤风险。

　　Preventing soup leakage is key. Products with poor sealing may have water leakage issues and pose a risk of burns during use.

　　检测方法：模拟盛装热汤后的颠簸或倾斜场景，检查是否渗漏。

　　Detection method: Simulate the bumpy or tilted scene after filling hot soup and check for leaks.

　　一次性汤杯

　　Disposable soup cup

　　三、感官质量：外观与气味符合标准

　　3、 Sensory quality: Appearance and odor meet standards

　　外观要求

　　Appearance requirements

　　表面平整光滑、色泽均匀，无杂质、裂纹或毛刺。

　　The surface is smooth and even in color, without impurities, cracks or burrs.

　　印刷清晰，无脱色或模糊现象。

　　The printing is clear without fading or blurring.

　　尽量选择无色透明产品，减少装饰图案可能带来的化学物质迁移风险。

　　Try to choose colorless and transparent products to reduce the risk of chemical migration caused by decorative patterns.

　　气味要求

　　Odor requirements

　　无异味或气味轻微易散。若打开杯盖后气味浓重，可能含有有害物质，应果断舍弃。

　　No odor or slight odor that easily disperses. If there is a strong odor after opening the cup lid, it may contain harmful substances and should be discarded decisively.

　　四、卫生标准：化学物质迁移量合规

　　4、 Hygiene standard: compliant migration of chemical substances

　　总迁移量

　　total migration

　　塑料制品中的化学物质在接触食品时可能迁移到食品中。总迁移量需符合国家标准（如GB 4806.7—2016），否则可能对人体健康造成影响。

　　Chemicals in plastic products may migrate into food when in contact with it. The total migration amount must comply with national standards (such as GB 4806.7-2016), otherwise it may have an impact on human health.

　　高锰酸钾消耗量

　　Potassium permanganate consumption

　　反映塑料杯中有机物分解的可能性。消耗量过大意味着卫生性能差，可能影响食品质量和安全。

　　Reflect the possibility of organic matter decomposition in plastic cups. Excessive consumption means poor hygiene performance, which may affect food quality and safety.

　　重金属检测

　　Heavy metal detection

　　确保塑料杯中重金属（如铅）含量不超标，避免对人体健康造成危害。

　　Ensure that the content of heavy metals (such as lead) in plastic cups does not exceed the standard to avoid harm to human health.

　　特定迁移量

　　Specific migration volume

　　包括邻苯类增塑剂、己内酰胺、对苯二甲酸等物质的迁移量，需符合相关标准。

　　The migration amount of substances such as phthalates, caprolactam, and terephthalic acid must comply with relevant standards.
