自封包装袋的购买要注意什么?

发布日期:2021-09-14 作者:www.jnsuliao.com 点击:

常购物中如果没有塑料袋,相信大家都会发现其中的不便,现在每个购物之处都会有大量的塑料袋,这些袋子或好或差,或多或少,但是都给人们的生活带来极大的便利。不过在这些塑料袋中,有不少人发现,有一些塑料袋上有企业的宣传标语和形象,而这种塑料袋就是专门定做的。
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.从色泽上判别背心袋的质量。色彩深的塑料袋通常都有毒,并且色彩越深越严重,塑料袋,尤以黑色为甚。可是这种办法不是的精确,有时候需要合作塑料背心袋的别的方面状况进行判别。
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.从手感上判别塑料袋的质量。无毒背心袋表面对比滑润,摸起来好像像打蜡了相同;相反,有毒的塑料袋摸起来不光滑,有黏着感。
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.颤动背心袋。用手捉住背心袋两个抓手,用力颤动背心袋,所宣布的杂音对比洪亮的话,则阐明袋子无毒,杂音沉闷则要当心。

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。将塑料袋按入水中,然后松手,能够天然浮起来的是无毒的,而不能浮起来的,则有毒。
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.焚烧法。无毒塑料袋是易燃,因为焚烧充沛,所以不会有拉丝的状况,而是迅速融化为泪滴状。有毒的塑料袋则不简单烧着,因为焚烧不充沛,甚至能够拉丝。
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.
