在日常生活中,塑料袋是否合格,你知道怎么辨认吗?

In daily life, do you know how to identify whether plastic bags are qualified?

1、首先要看塑料袋的外观是否有“食品用”的标志。通常这个标志应该在包装袋正面,比较醒目的位置。其次是看颜色,一般而言,有颜色的塑料袋大都使用了废旧塑料的回收料,是不能用来装食品的。比如,一些菜市场用来装鱼、虾等水产品或肉类的黑色塑料袋,原本是用来装垃圾的,消费者应避免使用。后,要看塑料袋塑料袋有无杂质。将塑料袋放在阳光或灯光下,看是否有黑点,有没有口子。有杂质的塑料袋,肯定是使用了废塑料做原料。

1. First of all, we should see whether the appearance of plastic bags has the sign of "food use". Usually, this sign should be on the front of the packaging bag in an eye-catching position. The second is to look at the color. Generally speaking, colored plastic bags mostly use the recycled materials of waste plastics, which can not be used to hold food. For example, some vegetable markets use black plastic bags for fish, shrimp and other aquatic products or meat, which were originally used to contain garbage, and consumers should avoid using them. After, it depends on whether there are impurities in the plastic bag. Put the plastic bag in the sun or light to see if there are black spots and holes. Plastic bags with impurities must use waste plastics as raw materials.

2、闻一闻塑料袋有无异味,是否让人觉得恶心。合格的塑料袋应该是无异味的,而不合格的塑料袋由于使用了添加剂,会带有各种味道。

2. Smell whether the plastic bag has peculiar smell and whether it makes people feel sick. Qualified plastic bags should be odor free, while unqualified plastic bags will have various flavors due to the use of additives.

3、合格的塑料袋具有一定强度,不会一撕就破;而不合格的塑料袋由于添加了杂质,往往强度很差,容易破裂。

3. Qualified plastic bags have certain strength and will not be torn at once; The unqualified plastic bags often have poor strength and are easy to crack due to the addition of impurities.

4、合格的塑料袋在抖动时,会发出清脆的声响;不合格的塑料袋往往是“嗡嗡”的闷响。

4. Qualified plastic bags will make a crisp sound when shaking; Unqualified plastic bags are often "buzzing" and stuffy.

5、把塑料袋放在水里,并用手将其按到水底,稍等片刻,浮出水面的即为塑料袋,沉在水底的即为有毒塑料袋。

5. Put the plastic bag in the water and press it to the bottom by hand. Wait a moment. The plastic bag that comes out of the water is the plastic bag, and the toxic plastic bag that sinks at the bottom is the toxic plastic bag.

6、用手抚摸塑料袋表面,很光滑是的。如果颜色混朦,触之发粘、发涩,就是有毒的。

6. Touch the surface of the plastic bag with your hand. It's very smooth. Yes. If the color is mixed, and the touch is sticky and astringent, it is toxic.

7、燃烧:将塑料袋剪下一角,放在火上一烧,烧之即燃,将它离开火后仍继续燃烧,并出现黄色火焰,而且熔塑像蜡烛一样一滴一滴往下掉,发出石蜡气味;有毒的,不易燃烧,燃烧后呈绿色火苗,并有一股呛鼻的异味。

7. Burning: cut off a corner of the plastic bag and put it on the fire. When it is burned, it will continue to burn after leaving the fire, and there will be a yellow flame. Moreover, the molten plastic will fall down like a candle, giving off the smell of paraffin; It is poisonous and not easy to burn. After burning, it shows a green flame and has a choking smell.
