服装包装袋厚度单位为丝，丝数越多则越厚越重，承重能力越好。1丝=0 01毫米，一般购物袋为双面5丝的，5丝以下属于普通薄款，5丝为中厚款，7丝-10丝左右为加厚款，14丝厚度为特厚款，承载力，可以反复使用。The thickness unit of clothing packaging bag is "silk" The more silk, the thicker and heavier it is, and the better its load-bearing capacity is 1 wire=0 01mm, the general supermarket shopping bag is dou

通过微生物来降解Degraded by microorganisms这种塑料袋是用一种可以被微生物分解的物质做成的。例如用玉米淀粉做成的塑料袋，在细菌、真菌等微生物的作用下进行，能够实现塑料袋的分解功能，而且本身使用的原材料也来源于大自然，不会对环境造成污染。This plastic bag is made of a material that can be decomposed by microorganisms For example, plastic bags made of corn starch can be decomposed under the action of bacteri

一、生产工艺流程1、 Production process flow二、印刷2、 Printing凹版印刷：是指将原稿上的文字、图案制成印版，在印版表面涂上油墨，通过压力使印版上的图文转移到被印材料的表面上，准确地、大量地复制出与原稿相同的印刷品。Gravure printing: refers to making a printing plate from the text and pattern on the original, applying ink on the surface of the printing plate, and transferring the image and text on the

一是吹膜，把塑料粒子倒入吹膜机通过加工热化制成塑料薄膜。这里塑料薄膜的优劣取决于塑料粒子的质量，的粒子吹出的薄膜比劣质的好。One is to blow film, which is to pour plastic particles into the film blowing machine to make plastic film by processing and heating Here, the quality of plastic film depends on the quality of plastic particles, and the film blown by high-quality particles is
