濟南食品塑料包裝袋的準確辨別方法

食品塑料包裝袋是人們生活中經常要用到的，但是使用的時候也一定要小心，有些塑料包裝袋是有毒的，不可以用來直接裝食物的。

Food plastic packaging bags are commonly used in people's daily lives, but caution must also be exercised when using them. Some plastic packaging bags are toxic and cannot be used directly to store food.

一、用眼睛觀察法

1、 Observation method with eyes

塑料袋呈白色，透明或微透明，質地均勻；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。

Non toxic plastic bags are white, transparent or slightly transparent, with a uniform texture; Toxic plastic bags are colored or white, but have poor transparency, are cloudy, have uneven surface stretching, and contain small particles.

二、用耳朵聽

2、 Listen with your ears

用手使勁抖動塑料袋時，發(fā)出清脆聲表明是塑料袋；而聲音小而悶的便是有毒塑料袋。

When shaking the plastic bag vigorously with your hands, a crisp sound indicates that it is a non-toxic plastic bag; And the one with a low and muffled sound is the toxic plastic bag.

三、用手摸

3、 Touch with your hands

用手撫摸塑料包裝袋表面，很光滑是的；發(fā)粘、發(fā)澀、有蠟狀感的是有毒的。

Touching the surface of the plastic packaging bag with your hand is very smooth and non-toxic; Sticky, astringent, and waxy hair are toxic.

四、用鼻子聞

4、 Smell with your nose

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。

Non toxic plastic packaging bags are odorless; Anything with a stimulating odor or abnormal taste is toxic.

五、沉水試驗法

5、 Submerged test method

把塑料袋放到水里，用手將其按到水底，稍等片刻，浮出水面的即為塑料包裝袋，沉在水底的即是有毒塑料包裝袋。

Put the plastic bag into the water, press it to the bottom with your hand, wait for a moment, the one that floats to the surface is the non-toxic plastic packaging bag, and the one that sinks to the bottom is the toxic plastic packaging bag.

六、燃燒法

6、 Combustion method

的塑料袋易燃，火焰尖 端呈黃色，局部呈青色，燃燒時像蠟燭淚一樣滴落，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。

Non toxic plastic bags are flammable, with a yellow flame tip and some areas appearing blue. When burned, they drip like candle tears and have a paraffin odor; Toxic plastic bags are not easy to burn and will extinguish immediately upon ignition. The flame tip is yellow or black, and the bottom is green. They soften and can be brushed, and a pungent odor can be smelled.
