市場上外賣打包袋的種類太多，在質量上更是不一樣，對于消費者來講，為了更好的選購使用外賣袋打包袋，有什么好的方法來判斷打包袋中是否添加了再生料呢？不了解的趕緊和小編一起來詳細了解看下吧！

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!

判斷打包袋是否添加了再生料可以從以下兩點入手：

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

1、看顏色，如果是加了再生料的打包袋，顏色會出現(xiàn)發(fā)黑的纖細那個，當然這個也是根據添加再生料的多少，相應的會有不一樣的顏色，一般來講添加再生料越多的，顏色就會越深，相反添加再生料少的，顏色就會相對淺一些。如果添加量相對較少，生產出質量更好的打包袋。如果沒有新材料作為比較，對于專業(yè)人員也是很難區(qū)分的，更不要講消費者了。

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、聞氣味，不添加再生料的打包袋，在氣味方面是很少的；相反的添加了再生料的塑料袋就會出現(xiàn)一股刺鼻的氣味，如果添加的少了，味道會相應的更小一些。

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、看韌性和拉力強度，對于再生料的打包袋，相對起來是比較容易破的，拉力強度和韌性等等也會相應變得很差。還有就是可能會具有毒性，對身體的危害性也是很大的，大家在使用的時候要謹慎。

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.
