隨著外賣行業(yè)的瘋狂野生發(fā)展，外賣打包袋的使用也在不算增加，那么市場上主流的打包袋有哪些呢？下面小編為您講解一番。

With the wild development of the takeout industry, the use of takeout packaging bags is not increasing, so what are the mainstream packaging bags in the market? Here's a brief introduction.

一：無紡布袋

1： Non woven 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. If there is no fiber floating on the surface, if there is no luster or a lot of floating silk, it is generally produced from recycled materials. Tear a piece of cloth, burn it completely with fire, and observe the combustion residues. Good products have few and flat residues, and the residues produced with inferior materials contain many small particles of dust. If time permits, one square meter of non-woven fabric can be exposed to the sun. The non-woven fabric with poor quality cannot withstand the sun's ultraviolet radiation. After seven days, there will be obvious changes. Once torn by hand, it is as easy to tear as paper.

無紡布的外觀指標(biāo)：隨機(jī)抽取檢測的樣品2米，在有光線的地方展開，目測布表面有無斷絲，硬塊等不合格疵點(diǎn)。

Appearance index of non-woven fabric: randomly select 2 meters of tested samples, spread them in places with light, and visually inspect the surface of the fabric for broken wires, hard blocks and other unqualified defects.

二：塑料袋

2： Plastic bag

由于價(jià)格低廉，塑料袋仍然是主流的打包材質(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?/div>
