  Touch observation: Touch the surface of the packaging box. Good packaging materials should be smooth and comfortable to the touch. If there are obvious bumps, roughness, or a sticky feeling on the surface, it may be due to the use of inferior materials or processing techniques.

  檢查標(biāo)識(shí):購(gòu)買食品包裝盒時(shí),注意檢查包裝上的標(biāo)識(shí)信息,包括生產(chǎn)日期、保質(zhì)期、制造商信息等。合格的食品包裝盒應(yīng)該標(biāo)有相關(guān)的認(rèn)證標(biāo)志,如QS標(biāo)志、食品安全標(biāo)志等。
