常購物中如果沒有塑料袋,相信大家都會發現其中的不便,現在每個購物之處都會有大量的塑料袋,這些袋子或好或差,或多或少,但是都給人們的生活帶來極大的便利。不過在這些塑料袋中,有不少人發現,有一些塑料袋上有企業的宣傳標語和形象,而這種塑料袋就是專門定做的。
If there are no plastic bags in regular shopping, I believe everyone will find the inconvenience. Now there are a large number of plastic bags in every shopping place. These bags are good or bad, more or less, but they all bring great convenience to people's life. However, in these plastic bags, many people found that some plastic bags have enterprise propaganda slogans and images, and this kind of plastic bag is specially customized.
1.從色澤上判別背心袋的質量。色彩深的塑料袋通常都有毒,并且色彩越深越嚴重,塑料袋,尤以黑色為甚。可是這種辦法不是的精確,有時候需要合作塑料背心袋的別的方面狀況進行判別。
1. Judge the quality of vest bag from color. Dark colored plastic bags are usually toxic, and the darker the color, the more serious it is. Plastic bags, especially black. However, this method is not 100% accurate. Sometimes it needs to cooperate with other aspects of plastic vest bags to judge.
2.從手感上判別塑料袋的質量。無毒背心袋表面對比滑潤,摸起來好像像打蠟了相同;相反,有毒的塑料袋摸起來不光滑,有黏著感。
2. Judge the quality of plastic bags from the hand feel. The surface of the non-toxic vest bag is relatively smooth and feels like waxing; On the contrary, toxic plastic bags do not feel smooth and adhesive.
3.顫動背心袋。用手捉住背心袋兩個抓手,用力顫動背心袋,所宣布的雜音對比洪亮的話,則闡明袋子無毒,雜音沉悶則要當心。

3. Vibrating vest bag. Grasp the vest bag with two hands and vibrate the vest bag with force. If the announced noise is relatively loud, it indicates that the bag is non-toxic, and be careful if the noise is dull.
4.塑料自封袋,沉浮法。將塑料袋按入水中,然后松手,能夠天然浮起來的是無毒的,而不能浮起來的,則有毒。
4. Plastic self sealing bag, sinking and floating method. Press the plastic bag into the water and let go. What can float naturally is non-toxic, while what cannot float is toxic.
5.焚燒法。無毒塑料袋是易燃,因為焚燒充沛,所以不會有拉絲的狀況,而是迅速融化為淚滴狀。有毒的塑料袋則不簡單燒著,因為焚燒不充沛,甚至能夠拉絲。
5. Incineration method. The non-toxic plastic bag is flammable. Because of abundant incineration, there will be no wire drawing, but it will melt into teardrop shape quickly. Toxic plastic bags are not easy to burn because they are not burned sufficiently and can even be brushed.
