在日常生活中,塑料袋是否合格,你知道怎么辨認嗎?
In daily life, do you know how to identify whether plastic bags are qualified?
1、要看塑料袋的外觀是否有“食品用”的標志。通常這個標志應該在包裝袋正面,比較醒目的位置。其次是看顏色,一般而言,有顏色的塑料袋大都使用了廢舊塑料的回收料,是不能用來裝食品的。比如,一些菜市場用來裝魚、蝦等水產(chǎn)品或肉類的黑色塑料袋,原本是用來裝垃圾的,消費者應避免使用。后,要看塑料袋塑料袋有無雜質。將塑料袋放在陽光或燈光下,看是否有黑點,有沒有口子。有雜質的塑料袋,肯定是使用了廢塑料做原料。
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、聞一聞塑料袋有無異味,是否讓人覺得惡心。合格的塑料袋應該是無異味的,而不合格的塑料袋由于使用了添加劑,會帶有各種味道。
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強度,不會一撕就破;而不合格的塑料袋由于添加了雜質,往往強度很差,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、合格的塑料袋在抖動時,會發(fā)出清脆的聲響;不合格的塑料袋往往是“嗡嗡”的悶響。
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,并用手將其按到水底,稍等片刻,浮出水面的即為塑料袋,沉在水底的即為有毒塑料袋。
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、用手撫摸塑料袋表面,很光滑是的。如果顏色混朦,觸之發(fā)粘、發(fā)澀,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、燃燒:將塑料袋剪下一角,放在火上一燒,燒之即燃,將它離開火后仍繼續(xù)燃燒,并出現(xiàn)黃色火焰,而且熔塑像蠟燭一樣一滴一滴往下掉,發(fā)出石蠟氣味;有毒的,不易燃燒,燃燒后呈綠色火苗,并有一股嗆鼻的異味。
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.
