First, choose formal channels and try to buy through formal channels, such as large supermarkets, stores, flagship stores and other formal stores.

二是看包装。应选择包装完好的产品，并仔细查看包装上的产品信息。应选择标有QS标志、生产许可证号、执行标准、制造商、生产地址等信息的产品，避免购买三无产品。注意生产日期和保质期，尽量选择保质期内的产品。

Second, look at the packaging. Select the products with intact packaging and carefully check the product information on the packaging. Products marked with QS mark, production license number, executive standard, manufacturer, production address and other information shall be selected to avoid purchasing three noes products. Pay attention to the production date and shelf life, and try to select products within the shelf life.

三是看外观。一次性纸质餐具产品:不要购买颜色太白或太灰的一次性纸质餐具产品。如果产品印刷，不要选择颜色太鲜艳的。印刷颜色越鲜艳，油墨中的重金属越容易超标。在产品储存和使用过程中，重金属可能会迁移到盛装的食物和饮料中，从而进入人体。另外，纸杯的杯口距杯体15mm以内，杯底距杯体10mm以内不能印刷。

Third, look at the appearance. Disposable paper tableware products: do not buy disposable paper tableware products with too white or too gray color. If the product is printed, do not choose too bright colors. The brighter the printing color, the more heavy metals in the ink are likely to exceed the standard. During the storage and use of the product, heavy metals may migrate into the food and beverage, thus entering the human body. In addition, the paper cup cannot be printed within 15mm from the cup mouth and 10mm from the cup bottom.

当然，与食物的直接接触面不应印刷。一次性塑料餐具:选择表面光滑、颜色均匀的产品，尽量选择没有装饰图案的无色透明产品。印刷油墨同样有可能重金属超标。一次性竹木筷子:选择颜色微黄、气味清香无刺激的一次性竹木筷子。注意长短适宜、无弯曲、无变形、无毛刺、无霉斑、表面洁净

Of course, direct contact with food should not be printed. Disposable plastic tableware: choose products with smooth surface and uniform color, and try to choose colorless and transparent products without decorative patterns. Printing ink may also exceed the standard of heavy metals. Disposable bamboo and wooden chopsticks: choose disposable bamboo and wooden chopsticks with yellowish color, fragrance and no stimulation. Pay attention to proper length, no bending, deformation, burr, mildew and clean surface
