塑料袋使用常識你都知道嗎?

雖然說塑料袋的廢棄問題一直沒有得到很好的解決,國際、都有相關(guān)規(guī)定,限制使用塑料袋,但生活中依然是離不開塑料袋。既然暫時離不開,那么如何選擇一些可靠合格的塑料袋,尤其是食品方面就顯得相當重要。

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.

,聞一聞有無異味,有異味請拒絕使用;不易撕壞的比容易撕壞的雜質(zhì)要少,好的塑料袋在抖動時,會發(fā)出清脆的響聲,不好的塑料袋一般是“嗡嗡”的悶響聲。

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.

燃燒塑料袋,的隨便點下就可以燃燒,離開打火機之后還可以燃燒,出現(xiàn)黃色火焰,像蠟燭一樣一滴一滴往下滴并發(fā)出石蠟的氣味。反之不易燃燒的、燃燒后是綠色火苗,有刺鼻異味的則是有毒塑料袋,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、菜市場一般用來裝海鮮的黑色塑料袋盡量避免使用,一般都是劣質(zhì)的。

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