市场上外卖打包袋的种类太多，在质量上更是不一样，对于消费者来讲，为了更好的选购使用外卖袋打包袋，有什么好的方法来判断打包袋中是否添加了再生料呢？不了解的赶紧和小编一起来详细了解看下吧！

There are too many types of takeout bags in the market, and their quality is even different. For consumers, in order to better choose and use takeout bags, what are the good methods to determine whether recycled materials are added to the bags? If you don't understand, hurry up and take a detailed look with the editor!

判断打包袋是否添加了再生料可以从以下两点入手：

To determine whether the packaging bag has added recycled materials, the following two points can be taken into consideration:

1、看颜色，如果是加了再生料的打包袋，颜色会出现发黑的纤细那个，当然这个也是根据添加再生料的多少，相应的会有不一样的颜色，一般来讲添加再生料越多的，颜色就会越深，相反添加再生料少的，颜色就会相对浅一些。如果添加量相对较少，生产出质量更好的打包袋。如果没有新材料作为比较，对于专业人员也是很难区分的，更不要讲消费者了。

1. Looking at the color, if it is a packaging bag with recycled materials added, the color will appear black and slender. Of course, this also depends on the amount of recycled materials added, and there will be different colors accordingly. Generally speaking, the more recycled materials added, the darker the color will be. On the contrary, the less recycled materials added, the lighter the color will be. If the amount added is relatively small, better quality packaging bags can be produced. Without new materials for comparison, it is also difficult for professionals to distinguish, let alone consumers.

2、闻气味，不添加再生料的打包袋，在气味方面是很少的；相反的添加了再生料的塑料袋就会出现一股刺鼻的气味，如果添加的少了，味道会相应的更小一些。

2. Smelling odors, packaging bags without adding recycled materials are rare in terms of odor; On the contrary, plastic bags with recycled materials will have a pungent odor, and if added less, the taste will be correspondingly smaller.

3、看韧性和拉力强度，对于再生料的打包袋，相对起来是比较容易破的，拉力强度和韧性等等也会相应变得很差。还有就是可能会具有毒性，对身体的危害性也是很大的，大家在使用的时候要谨慎。

3. Looking at toughness and tensile strength, for recycled material packaging bags, they are relatively easy to break, and tensile strength and toughness will also become very poor accordingly. Another possibility is that it may be toxic and pose significant harm to the body. Therefore, caution should be exercised when using it.
