济南食品塑料包装袋的准确辨别方法

食品塑料包装袋是人们生活中经常要用到的，但是使用的时候也一定要小心，有些塑料包装袋是有毒的，不可以用来直接装食物的。

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、用眼睛观察法

1、 Observation method with eyes

塑料袋呈白色，透明或微透明，质地均匀；有毒塑料袋则为彩色或虽为白色，但透明度差，较浑浊，塑料表面拉伸不均匀，有小颗粒。

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、用耳朵听

2、 Listen with your ears

用手使劲抖动塑料袋时，发出清脆声表明是塑料袋；而声音小而闷的便是有毒塑料袋。

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

用手抚摸塑料包装袋表面，很光滑是的；发粘、发涩、有蜡状感的是有毒的。

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、用鼻子闻

4、 Smell with your nose

的塑料包装袋是无味的；有刺激气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、沉水试验法

5、 Submerged test method

把塑料袋放到水里，用手将其按到水底，稍等片刻，浮出水面的即为塑料包装袋，沉在水底的即是有毒塑料包装袋。
