Packaging bags are closely related to our life. With the rise of productivity, there is an increasing demand for products and more varieties. What should we pay attention to when choosing packaging bags?

1.食品用包裝袋的外部包裝有標識，主要是廠名、廠址、產品名稱，并在明顯處注明食品用字樣，產品出廠后均附有產品檢驗合格證。

2. Food packaging bags are tasteless when leaving the factory, and products with special smell cannot be used in the food industry.

3. Colored bags cannot be used for food, such as black or dark red. In the final analysis, the Jedi is because the bags with too dark color are made of recycled materials.

4.選用不含有鍍層的材料?，F代包裝設計中，為了使產品更加耐用、美觀，很多企業選擇使用添加大量的鍍層材料，種種行為不僅給產品材料回收帶來了困難，而且大部分涂料本身就具有毒性，若是食用會對人體產生危害。另外涂、鍍工藝過程也給環境帶來污染，涂料揮發毒性溶劑氣體，電鍍時產生含鉻等重金屬的廢液、廢渣污染等。

4. Select materials without coating. In modern packaging design, in order to make products more durable and beautiful, many enterprises choose to use and add a large number of coating materials. Various behaviors not only bring difficulties to product material recycling, but also most of the coatings themselves are toxic, which will be harmful to human body if eaten. In addition, the coating and plating process also brings pollution to the environment. The coating volatilizes toxic solvent gas, and the waste liquid and residue containing chromium and other heavy metals are polluted during electroplating.

5.由于食品用包裝袋不易降解的特性，易會造成環境污染，因此，采購食品時選用綠色包裝材料，保護我們生活的家園是每個人應盡的責任。

5. Due to the non degradable characteristics of food packaging bags, it is easy to cause environmental pollution. Therefore, it is everyone's responsibility to select green packaging materials when purchasing food and protect our home.
