外賣打包袋一般都是紙袋或是塑料袋，塑料袋大部分都是以純白色為主，而且還會有著透明度，除此之外，用手觸摸質地比較柔軟，也并不會有明顯的異味，這就說明塑料袋的質量還是比較靠譜的。下面來看看選擇外賣打包袋的方法：

Delivery bags are usually made of paper or plastic. Most plastic bags are made of pure white and have transparency. In addition, the texture is relatively soft when touched by hand and there is no obvious odor, indicating that the quality of plastic bags is relatively reliable. Let's take a look at the method of choosing a takeout bag:

1、先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。

1. First, you need to check if the appearance of the plastic bag has a "food use" label. Usually, this sign should be prominently placed on the front of the packaging bag.

2、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、蝦等水產品或肉類的劣質黑色塑料袋，或者是原本是用來裝垃圾的塑料袋，消費者都應避免使用。

2. Secondly, it depends on the color. Generally speaking, plastic bags with colors mostly use recycled materials from waste plastics and cannot be used to hold food. For example, consumers should avoid using inferior black plastic bags used in some food markets to hold fish, shrimp, and other aquatic products or meat, or plastic bags originally used to hold garbage.

3、要看塑料袋有無雜質。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。

3. It depends on whether the plastic bag contains impurities. Place the plastic bag in sunlight or light to see if there are any black spots or cuts. Plastic bags with impurities must have used waste plastic as raw material.

4、聞一聞塑料袋有沒有味道，是否讓人覺得惡心。合格的塑料袋應該是沒有味道的，而不合格的塑料袋由于使用了添加劑，會帶有各種味道。

4. Smell if the plastic bag has a smell and if it makes people feel nauseous. Qualified plastic bags should be odorless, while unqualified plastic bags may carry various flavors due to the use of additives.

5、合格的塑料袋具有相應強度，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。

5. Qualified plastic bags have corresponding strength and will not break easily; Unqualified plastic bags, due to the addition of impurities, often have poor strength and are prone to cracking.

6、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。

6. Qualified plastic bags will make a crisp sound when shaking; Unqualified plastic bags often have a "buzzing" sound.

7、把塑料袋放在水里，并用手將其按到水底，稍等片刻，浮出水面的即為不合格塑料袋，沉在水底的即為有毒塑料袋。

7. Place the plastic bag in the water and press it down to the bottom with your hand. Wait for a moment. Those that surface are considered unqualified plastic bags, while those that sink to the bottom are considered toxic plastic bags.

8、用手撫摸塑料袋表面，表面應該是光滑的。如果顏色混朦，觸之發(fā)粘、發(fā)澀，就是有毒的。

8. Touch the surface of the plastic bag with your hand, and the surface should be smooth. If the color is mixed and sticky or astringent when touched, it is toxic.

9、燃燒：將塑料袋剪下一角，放在火上一燒，合格的燒之即燃，將它離開火后仍繼續(xù)燃燒，并出現黃色火焰，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。

9. Burning: Cut off a corner of the plastic bag and place it on the fire. Qualified ones will ignite immediately. After leaving the fire, they will continue to burn and a yellow flame will appear, and the molten plastic will drop down like a candle, emitting a smell of paraffin; Toxic, not easily flammable, with a green flame and a pungent odor after combustion.
