目前市場上主流的打包袋有以下幾種：

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

　　一：無紡布袋

1： Non woven fabric bag

　　無紡布布面物理指標(biāo)：觀察布面是否有光澤。有沒有纖維浮在表面，如果無光澤或者浮絲多的話，大抵是回料生產(chǎn)的。撕一塊布，用火燃燒完全，觀察燃燒殘留物，好的產(chǎn)品，殘留物少且是平整的，次料生產(chǎn)的，殘留物有很多微小的顆粒粉塵。如果時(shí)間允許，可以取一平方米在日光下暴曬，質(zhì)量差的無紡布是經(jīng)不住日光紫外線的照射的，7天后就有很明顯的變化，用手一撕，就和紙一樣的容易撕破。

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

　　由于價(jià)格低廉，塑料袋仍然是最主流的打包材質(zhì)之選。塑料袋還是具有很多的優(yōu)點(diǎn)，其中最主要就是他的塑型能力強(qiáng)，扎緊后可以完全貼合打包盒，使內(nèi)部不容易打翻或?yàn)⒙?。其?，通常使用其他類型的打包袋都必須配合訂書機(jī)才能固定封口，但使用塑料袋就可以省去這道工序了塑料打包袋分為很多等級，普通的塑料袋只能用于外包裝打包。而如果是直接接觸食物的塑料袋則要求是食品級，必須附有標(biāo)識。

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

　　另外一種很受到商家青睞的，是用塑料袋很相近的束口袋，是塑料袋的衍生品，可以被做成五顏六色的底色，并充分搭配自己的設(shè)計(jì)。并且上方的抽繩設(shè)計(jì)，將餐品放入袋中，只需一抽一提，口袋即能封口，緊緊包裹打包盒，塑形力強(qiáng) ，并省去了裝訂的步驟。束口袋可能更適合單品的商家，因?yàn)閮?nèi)部空間較小，多放幾個(gè)產(chǎn)品，束口塑形的功效就會大打折扣。

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：紙袋

4： Paper bags

　　受到西餐品類的高度追崇，可能是在西方，環(huán)保意識比較領(lǐng)先，使用紙袋本身就是傳統(tǒng)。通常在市場上流通的有黃牛皮紙和白牛皮紙，普通紙，和雞蛋紙，價(jià)格因尺寸和厚度有所差異。其實(shí)我們不能只講紙袋，而是把主角換成“紙”這個(gè)材質(zhì)，因?yàn)椴粌H僅有紙袋一個(gè)形態(tài)，還有紙盒等等，這也說明了紙的可塑性非常強(qiáng)。

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.
