虽然说塑料袋的废弃问题一直没有得到很好的解决，国际、都有相关规定，限制使用塑料袋，但生活中依然是离不开塑料袋。既然暂时离不开，那么如何选择一些可靠合格的塑料袋，尤其是食品方面就显得相当重要。

Although the problem of plastic bag disposal has not been well solved, and there are relevant regulations at the international and national levels that restrict the use of plastic bags, plastic bags are still indispensable in daily life. Since we cannot do without it temporarily, it is quite important to choose some safe, reliable and qualified plastic bags, especially in the food industry.

，闻一闻有无异味，有异味请拒绝使用；不易撕坏的比容易撕坏的杂质要少，好的塑料袋在抖动时，会发出清脆的响声，不好的塑料袋一般是“嗡嗡”的闷响声。

Firstly, smell for any odor. If there is any odor, please refuse to use; Impurities that are not easily torn off are fewer than those that are easily torn off. Good plastic bags make a crisp sound when shaken, while bad plastic bags generally make a dull buzzing sound.

其次，把塑料袋按到水里，能自己浮出水面的是塑料袋，沉在水底的就是有毒塑料袋，不可使用。

Secondly, press the plastic bag into the water. The non-toxic plastic bag that can surface on its own and the toxic plastic bag that sinks to the bottom of the water cannot be used.

燃烧塑料袋，的随便点下就可以燃烧，离开打火机之后还可以燃烧，出现黄色火焰，像蜡烛一样一滴一滴往下滴并发出石蜡的气味。反之不易燃烧的、燃烧后是绿色火苗，有刺鼻异味的则是有毒塑料袋，不可使用

Burning plastic bags are non-toxic and can burn easily when lit. After leaving the lighter, they can still burn, producing a yellow flame that drops down like a candle and emits a smell of paraffin. On the contrary, those that are not easily combustible and have a green flame after combustion, while those with a pungent odor are toxic plastic bags that cannot be used

再次、菜市场一般用来装海鲜的黑色塑料袋尽量避免使用，一般都是劣质的。

Again, black plastic bags used to hold seafood in markets should be avoided as they are generally of poor quality.
