外賣打包袋是人們生活中經(jīng)常要用到的,但是使用的時(shí)候也一定要小心,有些外賣打包袋是有毒的,如何識別哪種膠袋有毒,哪種無毒呢?
Take away bags are often used in people's lives, but you must be careful when using them. Some take away bags are toxic. How to identify which plastic bags are toxic and which are non-toxic?
1、用手摸:用手撫摸塑料包裝袋表面,很光滑是無毒的;發(fā)粘、發(fā)澀、有蠟狀感的是有毒的。
1. Touch with hands: touch the surface of the plastic packaging bag with hands, which is very smooth and non-toxic; Sticky, astringent and waxy are poisonous.
2、用耳朵聽:用手使勁抖動(dòng)塑料袋時(shí),發(fā)出清脆聲表明是無毒塑料袋;而聲音小而悶的便是有毒塑料袋。
2. Listen with your ears: When shaking the plastic bag with your hands, it makes a clear sound indicating that it is non-toxic plastic bag; The noise is small and stuffy is toxic plastic bags.
3、肉眼察法:無毒塑料袋呈白色,透明或微透明,質(zhì)地均勻;有毒塑料袋則為彩色或雖為白色,但透明度差,較渾濁,塑料表面拉伸不均勻,有小顆粒。
3. Visual inspection: non-toxic plastic bag is white, transparent or slightly transparent, with uniform texture; Toxic plastic bags are colored or white, but their transparency is poor and turbid. The plastic surface is unevenly stretched with small particles.
4、用鼻子聞膠袋:無毒的塑料包裝袋是無味的;有刺激氣味或味道不正常的是有毒的。
4. Smell plastic bags with your nose: non-toxic plastic bags are tasteless; Those with pungent smell or abnormal taste are toxic.

5、沉水試驗(yàn)法:把塑料袋放到水里,用手將其按到水底,稍等片刻,浮出水面的即為無毒塑料包裝袋,沉在水底的即是有毒塑料包裝袋。
5. Submerged test method: put the plastic bag in water, press it to the bottom with your hand, wait for a moment, and the non-toxic plastic packaging bag will emerge from the water, and the toxic plastic packaging bag will sink to the bottom.
6、燃燒法:無毒的塑料袋易燃,火焰尖端呈黃色,局部呈青色,燃燒時(shí)像蠟燭淚一樣滴落,有石蠟味;有毒的塑料袋不易燃燒,離火即熄,火焰尖端呈黃色、或是黑色,底部呈綠色,軟化能拉絲、還可以聞到一股刺鼻的味。
6. Combustion method: non-toxic plastic bag is flammable, the tip of the flame is yellow, and part of it is cyan. When burning, it drops like candle tears, with a wax smell; The poisonous plastic bag is not easy to burn, and will extinguish when it is away from the fire. The tip of the flame is yellow or black, and the bottom is green. It can be softened and brushed, and you can smell a pungent smell.
