PE bags we usually is not a pure substance used, the preparation of which is made ??of many materials. Wherein the polymer (or synthetic resin) is the main component of plastic, in addition, in order to improve the performance of plastics, but also add a variety of auxiliary materials such as fillers, plasticizers, lubricants, stabilizers in the polymer, coloring agents, in order to become a good performance PE bags. PE plastic structural features: ① most pe bag light, chemically stable, will not rust; ② good impact resistance; ③ has good transparency and abrasion resistance; ④ insulation, and low thermal conductivity ; ⑤ general formability, good color, low processing cost; ⑥ most plastics poor heat resistance, thermal expansion, and easy burning; ⑦ poor dimensional stability, easily deformed; ⑧ most plastics poor low-temperature resistance, low temperature brittle under; ⑨ easy to aging; ⑩ certain plastics soluble in solvents. 0 && image.height> 0) {if (image.width> = 700) {this.width = 700; this.height = image.height * 700/image.width;}} "alt =" "src =" hdpack -sh/upfiles/2014531105011.jpg "width = 500 height = 375 data-mce-src =" hdpack-sh/upfiles/2014531105011.jpg "> For more information, please visit: Composite zipper bag hdpack-sh/products-detail . asp? cpid = 103
