　　一、塑料餐具01选购提示

　　1、 Plastic tableware 01 purchase tips

　　1.材质标识要看清：查看产品说明，优先选择标有 “食品接触用” 字样、材质为聚丙烯（PP）或聚乙烯（PE）等，这类材质安全性较高。例如，常见的 PP 材质塑料饭盒，在正常使用温度下较为稳定。2.外观检查不可少：挑选时，确保餐具表面光滑，无毛刺、气泡、杂质或异味。若餐具边缘粗糙，可能会划伤嘴巴；有刺鼻气味，可能存在有害物质挥发。3.购买渠道要正规：建议前往正规超市、商场或信誉良好的电商平台购买，这些渠道的产品质量更有保障，可减少买到三无产品的风险。

　　1. Material identification should be clear: Check the product description and prioritize selecting materials labeled "for food contact" such as polypropylene (PP) or polyethylene (PE), which have higher safety. For example, common PP plastic lunch boxes are relatively stable at normal operating temperatures. 2. Appearance inspection is essential: When selecting, ensure that the surface of the tableware is smooth, without burrs, bubbles, impurities, or odors. If the edges of the tableware are rough, it may scratch the mouth; There is a pungent odor and there may be harmful substances evaporating. 3. Regular purchasing channels: It is recommended to go to regular supermarkets, shopping malls, or reputable e-commerce platforms to purchase. The quality of products from these channels is more guaranteed, which can reduce the risk of buying three no products.

　　1.避免高温加热：绝不能将普通塑料餐具放入微波炉、烤箱等高温设备中加热，高温易使塑料变形，还可能导致其中的有害物质迁移到食物中。如需微波加热，务必使用标有 “可微波” 字样的塑料餐具。2.及时清洗防残留：使用后尽快清洗塑料餐具，尤其是盛装过油腻、含糖食物后，避免食物残渣残留滋生细菌。清洗时，用温和的洗洁精和清水冲洗，不要使用钢丝球等尖锐工具，以免刮伤餐具表面。3.定期更换保安全：若塑料餐具出现明显磨损、变色、变形或有裂纹，应及时更换。长期使用老化的塑料餐具，有害物质渗出风险增加。

　　1. Avoid high temperature heating: Ordinary plastic tableware should never be placed in high-temperature equipment such as microwave ovens or ovens for heating. High temperatures can easily deform plastics and may also cause harmful substances to migrate into food. If microwave heating is required, be sure to use plastic tableware marked with the words "microwave ready". 2. Timely cleaning to prevent residue: Clean plastic tableware as soon as possible after use, especially after containing greasy or sugary food, to avoid the growth of bacteria caused by food residue. When cleaning, rinse with mild detergent and clean water. Do not use sharp tools such as steel wool to avoid scratching the surface of the tableware. 3. Regular replacement for safety: If plastic tableware shows obvious wear, discoloration, deformation, or cracks, it should be replaced in a timely manner. Long term use of aged plastic tableware increases the risk of harmful substances seeping out.

　　二、保鲜膜01选购提示

　　2、 Tips for purchasing cling film 01

　　1.材质特性需了解：保鲜膜常见材质有聚乙烯（PE）、聚氯乙烯（PVC）和聚偏二氯乙烯（PVDC）。PE 保鲜膜安全系数高，可用于日常食品包装；PVC 保鲜膜因含有塑化剂，不适合包裹油脂类食物；PVDC 保鲜膜成本高，多用于熟食包装。购买时看清材质说明。2.外观质量严把关：选择表面平整、无气泡、无杂质、无异味的保鲜膜。轻轻拉扯，具有良好拉伸性、不易破裂的产品质量更佳。3.正规产品更放心：从正规渠道购买，确保产品包装完好，有清晰的品牌、生产日期、保质期及使用说明等标识。

　　1. Material characteristics need to be understood: Common materials for cling film include polyethylene (PE), polyvinyl chloride (PVC), and polyvinylidene chloride (PVDC). PE cling film has a high safety factor and can be used for daily food packaging; PVC cling film is not suitable for wrapping oily food due to the presence of plasticizers; PVDC cling film has a high cost and is often used for packaging cooked food. Please read the material instructions carefully when purchasing. 2. Strict quality control of appearance: Choose plastic wrap with a smooth surface, no bubbles, no impurities, and no odors. Gently pulling, products with good stretchability and less prone to breakage have better quality. 3. Regular products are more reassuring: Purchase from regular channels to ensure that the product packaging is intact, with clear brand, production date, shelf life, and instructions for use.

　　02 Usage tips

　　1.正确包裹防交叉：包裹食物时，尽量排出空气，以延长保鲜时间。注意生熟食品要分开包裹，防止交叉污染。2.注意使用温度：普通保鲜膜不耐高温，不能直接在微波炉中加热。若需微波加热，应使用专门的可微波保鲜膜，并遵循产品说明操作。3.避免长期接触油脂：油脂会加速保鲜膜中有害物质的迁移，因此尽量不要用保鲜膜长时间包裹油炸食品、肥肉等高油脂食物。

　　1. Proper packaging to prevent cross wrapping: When wrapping food, try to exhaust air as much as possible to extend the shelf life. Please package raw and cooked food separately to prevent cross contamination. 2. Pay attention to the usage temperature: Ordinary cling film is not resistant to high temperatures and cannot be directly heated in a microwave oven. If microwave heating is required, specialized microwaveable cling film should be used and the product instructions should be followed. 3. Avoid long-term exposure to oil: Oil can accelerate the migration of harmful substances in cling film, so try not to wrap high-fat foods such as fried foods and fatty meat with cling film for a long time.

　　1.正确存放保质量：未使用的食品包装袋应存放在干燥、阴凉处，避免阳光直射和高温环境，防止老化变质。2.避免重复使用：一次性食品包装袋在使用后，即使外观完好，也不建议重复使用，以防细菌滋生和有害物质渗出。3.注意包装食品特性：对于容易产生气体的食品，如发酵食品，不要将包装袋密封过紧，以防胀袋破裂。

　　1. Proper storage to ensure quality: Unused food packaging bags should be stored in a dry, cool place, away from direct sunlight and high temperature environments, to prevent aging and deterioration. 2. Avoid reuse: Disposable food packaging bags, even if they look good after use, are not recommended for reuse to prevent bacterial growth and harmful substances from seeping out. 3. Pay attention to the characteristics of packaged food: For foods that are prone to gas production, such as fermented foods, do not seal the packaging bag too tightly to prevent the bag from bursting.
