無紡布袋都是什么材質的

無紡布是一種非織造布，它直接利用高聚物切片、短纖維或長絲通過各種纖網成形方法和固結技術形成的具有柔軟、透氣和平面結構的新型纖維制品。
Non woven fabric is a kind of nonwovens, which directly uses polymer chips, short fibers or filaments to form a new type of fiber products with soft, breathable and plane structure through various web forming methods and consolidation technology.
無紡布袋相較于傳統塑料袋的優點：無紡布袋價廉物美，環保實用，應用廣泛，有突出的廣告位置。適用于各類業務活動及展覽展銷會，是企事業單位理想的廣告促銷禮品贈品.
Compared with traditional plastic bags, non-woven bags have the following advantages: low price, good quality, environmental protection, wide application and prominent advertising position. It is suitable for all kinds of business activities, exhibitions and sales fairs

無紡布袋廠家的原材料是聚丙烯，而塑料袋的原材料是聚乙烯，兩種物質雖然名字相似，但在化學結構上卻相差甚遠。聚乙烯的化學分子結構具有相當強的穩定性，極難降解，所以塑料袋需要300年才可分解完畢;而聚丙烯的化學結構不牢固，分子鏈很容易就可斷裂，從而可以有效地降解， 并且在無毒的形態中進入下一步環境循環，一個無紡布袋在90天內就可以徹底分解。
Polypropylene is the raw material of non-woven bag manufacturers, while polyethylene is the raw material of plastic bags. Although the names of the two substances are similar, their chemical structures are quite different. The chemical molecular structure of polyethylene is very stable and difficult to degrade, so it takes 300 years for the plastic bag to decompose completely; while the chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, so it can be effectively degraded, and the next environmental cycle can be carried out in the non-toxic form, and a non-woven bag can be completely decomposed within 90 days.
無紡布就是不需要紡織過程而做成似布非布的產品，也叫不織布。因為它是只需將紡織短纖維或者長絲進行定向或隨機撐列，形成纖網結構，然后采用機械、熱粘或化學等方法加固即可制成。無紡布袋多數是紡粘無紡布制成。
