目前市场上主流的打包袋有以下几种：

At present, there are several mainstream packaging bags in the market:

　　一：无纺布袋

1： Non woven fabric bag

　　无纺布布面物理指标：观察布面是否有光泽。有没有纤维浮在表面，如果无光泽或者浮丝多的话，大抵是回料生产的。撕一块布，用火燃烧完全，观察燃烧残留物，好的产品，残留物少且是平整的，次料生产的，残留物有很多微小的颗粒粉尘。如果时间允许，可以取一平方米在日光下暴晒，质量差的无纺布是经不住日光紫外线的照射的，7天后就有很明显的变化，用手一撕，就和纸一样的容易撕破。

Physical indicators of non-woven fabric surface: observe whether the fabric surface has luster. Is there any fiber floating on the surface? If there is no gloss or a lot of floating silk, it is mostly produced from recycled materials. Tear a piece of cloth and burn it completely with fire. Observe the combustion residue. Good products have few and even residues, and the residue produced from secondary materials contains many small particles of dust. If time permits, one square meter of non-woven fabric can be taken and exposed to sunlight. Poor quality non-woven fabric cannot withstand the exposure of sunlight and ultraviolet rays. After 7 days, there will be significant changes. When torn by hand, it is as easy to tear as paper.

　　二：塑料袋

2： Plastic bags

　　由于价格低廉，塑料袋仍然是最主流的打包材质之选。塑料袋还是具有很多的优点，其中最主要就是他的塑型能力强，扎紧后可以完全贴合打包盒，使内部不容易打翻或洒漏。其二 ，通常使用其他类型的打包袋都必须配合订书机才能固定封口，但使用塑料袋就可以省去这道工序了塑料打包袋分为很多等级，普通的塑料袋只能用于外包装打包。而如果是直接接触食物的塑料袋则要求是食品级，必须附有标识。

Due to its low price, plastic bags are still the most mainstream packaging material choice. Plastic bags still have many advantages, among which the most important is their strong shaping ability. After being tied tightly, they can fully fit the packaging box, making the interior less prone to tipping over or spillage. Secondly, usually other types of packaging bags must be used in conjunction with a stapler to secure the seal, but using plastic bags can eliminate this process. Plastic packaging bags are divided into many levels, and ordinary plastic bags can only be used for outer packaging. If it is a plastic bag that comes into direct contact with food, it is required to be food grade and must be labeled.

　　三：束口袋

3： Bundle pocket

　　另外一种很受到商家青睐的，是用塑料袋很相近的束口袋，是塑料袋的衍生品，可以被做成五颜六色的底色，并充分搭配自己的设计。并且上方的抽绳设计，将餐品放入袋中，只需一抽一提，口袋即能封口，紧紧包裹打包盒，塑形力强 ，并省去了装订的步骤。束口袋可能更适合单品的商家，因为内部空间较小，多放几个产品，束口塑形的功效就会大打折扣。

Another type that is highly favored by businesses is the use of plastic bags, which are similar to the bundle pockets. They are derivatives of plastic bags and can be made into colorful backgrounds, fully matching their own designs. And with the drawstring design above, the food can be placed in the bag. With just a pull and lift, the bag can be sealed, tightly wrapped around the packaging box, with strong shaping force and eliminating the need for binding. Bundle pockets may be more suitable for single item merchants because the internal space is smaller. Placing more products will greatly reduce the shaping effect of the bundle mouth.

　　四：纸袋

4： Paper bags

　　受到西餐品类的高度追崇，可能是在西方，环保意识比较领先，使用纸袋本身就是传统。通常在市场上流通的有黄牛皮纸和白牛皮纸，普通纸，和鸡蛋纸，价格因尺寸和厚度有所差异。其实我们不能只讲纸袋，而是把主角换成“纸”这个材质，因为不仅仅有纸袋一个形态，还有纸盒等等，这也说明了纸的可塑性非常强。

Highly favored by Western food categories, perhaps due to the leading environmental awareness in the West, the use of paper bags is already a tradition. Usually circulating in the market are yellow kraft paper and white kraft paper, regular paper, and egg paper, with prices varying depending on size and thickness. In fact, we cannot just talk about paper bags, but instead replace the protagonist with the material "paper", because there is not only a form of paper bags, but also paper boxes and so on, which also shows that the plasticity of paper is very strong.
