如何識別劣質塑料袋?

發布日期:2021-10-12 作者:www.mable0326.com 點擊:

通過色彩來分辨
Distinguish by color
食品用塑料袋大多為透明塑料袋,也就是不帶有明顯的顏色。在菜市場常能看見一些商販用紅色、黑色等彩色塑料袋裝果蔬、熟食及肉類等。事實上,這種彩色塑料袋大多都是添加廢舊回收料制成的,是不符合食品要求的。
Most plastic bags for food are transparent plastic bags, that is, they do not have obvious colors. In the vegetable market, some vendors can often be seen packing fruits and vegetables, cooked food and meat in red, black and other colored plastic bags. In fact, most of these colored plastic bags are made of waste recycled materials, which do not meet the food requirements.
通過眼睛來識別
Recognize by eyes
即使塑料袋是透明的,也要放在光線好的地方看看有無雜質。劣質的塑料袋如果對著燈光仔細看,可以看到塑料袋上面有黑色的小點,小點分布不均勻,大小不一,甚至還可以在劣質塑料袋上看到裂口。劣質塑料袋通常用來盛裝垃圾,不能盛裝食品、果蔬及肉類。
Even if the plastic bag is transparent, it should be placed in a place with good light to see if there are impurities. If you look at the poor plastic bag carefully against the light, you can see that there are black dots on the plastic bag. The dots are unevenly distributed and of different sizes. You can even see cracks on the poor plastic bag. Inferior plastic bags are usually used to contain garbage, not food, fruits, vegetables and meat.

通過鼻子來鑒別
Identify by nose
由于劣質的塑料袋是用廢舊回收料合成的,所以,用鼻子聞一下塑料袋里面,會聞到惡心的氣味,這種塑料袋通常是有毒性的,不能用來盛裝食物和蔬菜。優質塑料袋是沒有什么氣味的。
Because inferior plastic bags are synthesized from waste recycled materials, smelling the inside of plastic bags with your nose will smell disgusting smell. This kind of plastic bags are usually toxic and can not be used to contain food and vegetables. High quality plastic bags have no smell.
通過手來感覺
Feel through your hands
質量好的塑料袋表面光滑、致密、平整,而劣質塑料袋表面比較粗糙,用手觸摸會感覺表面凹凸不平,發粘、發澀。
The surface of high-quality plastic bags is smooth, dense and flat, while the surface of low-quality plastic bags is rough. If you touch it with your hand, you will feel that the surface is uneven, sticky and astringent.
通過重量來判斷
Judging by weight
把塑料袋丟入水中,如果塑料袋沉入到水底,就說明塑料袋是劣質的,如果塑料袋漂在水面上,就說明塑料袋質量較好。新料制成的塑料袋,具有一定的強度、硬度、韌性,不會一撕就壞。而劣質塑料袋在制作的過程中,需要加入很多添加劑及廢舊回收料,這些添加劑及廢舊回收料不但會有很濃烈的氣味,還會讓塑料袋變得很脆、易碎,徒手可以很容易就將塑料袋撕裂。
Throw the plastic bag into the water. If the plastic bag sinks to the bottom, it means that the plastic bag is of poor quality. If the plastic bag floats on the water, it means that the plastic bag is of good quality. The plastic bag made of new material has certain strength, hardness and toughness, and will not be damaged once torn. In the process of making inferior plastic bags, many additives and waste recycling materials need to be added. These additives and waste recycling materials will not only have a strong smell, but also make the plastic bags brittle and fragile. It is easy to tear the plastic bags with bare hands.
通過聲音來區分
Distinguish by sound
把塑料袋拿在手中,用力抖一抖,如果塑料袋發出清脆的響聲,說明塑料袋是劣質的,而質量好的塑料袋在抖動時會發出嗡嗡的聲響。
Hold the plastic bag in your hand and shake it hard. If the plastic bag makes a crisp sound, it means that the plastic bag is of poor quality, while the high-quality plastic bag will make a buzzing sound when shaking.
