在塑料包装袋定做时，也可以生产出多种颜色的产品，但是在使用有色塑料袋的时候，需要注意存在的一些问题。

 

When the plastic packaging bag is customized, it can also produce a variety of color products, but when using colored plastic bags, we need to pay attention to some problems.

 

有色塑料袋可能是回收处理的，尽管这些塑料袋在加工之前，都经过了洗涤、粉碎等程序，但它们在被回收之前装过什么东西我们却不知道。它们以前也有可能装过有害物质，不可能凭着洗涤就能简单的除掉这些有害物质。所以许多人会用五颜六色的塑料袋，从菜市场或农贸市场带回青菜、水果，甚用有色塑料袋来装早点或烧烤的鸡翅、油饼等食品，这些都是需要注意的。

 

Colored plastic bags may be recycled. Although these plastic bags go through washing, crushing and other procedures before processing, we don't know what they contain before being recycled. They may have contained harmful substances before, and it is impossible to simply remove these harmful substances by washing. Therefore, many people will use colorful plastic bags to bring back green vegetables and fruits from the vegetable market or farmers' market, and even use colored plastic bags to hold breakfast or barbecue chicken wings, oil cakes and other food. These all need attention.

 

所以尽量还是使用白色或无色透明的塑料袋，更加提倡使用菜篮子或自己携带的食品塑料袋，避免对人体产生危害。

 

Therefore, try to use white or colorless transparent plastic bags, and more advocate the use of vegetable baskets or their own food plastic bags to avoid harm to human body.
