Patent name Color printing film Aluminized rice packaging bag composite layer and its processing technology Patent applicant Dai Zhiguang Principal applicant Address 325804 Xinshi Street, Yishan Town, Cangnan County, Zhejiang Province Inventor Dai Zhiguang; Guo Heqian; Dai Meixing Application (Patent) No. 200510026499.4 Application date 2005.06.02 Certification date Approval announcement number 1721287 Approval announcement date 2006.01.18 Manual CD-ROM number D0603-1 Main classification number B65D65/40 (2006.01) I Classification number B65D65/40 (2006.01) I; B65D30/02 (2006.01 ) I; B32B27/00 (2006.01) I; B32B37/00 (2006.01) I; B65D85/00 (2006.01) I Abstract This invention is a color printing film aluminized rice packaging bag composite layer and its processing technology, characterized in that Color printing aluminized film 5 is directly plated on a layer of color-printed PET color printing film, and then this layer of PET color printing aluminized film 5 is processed by hot-melt adhesive and another layer of polypropylene woven bag 4 Into the color printing film aluminum rice packaging bag composite layer. Compared with the prior art, the present invention has the following advantages: (1) The processing technology is simple, the processing procedure is simplified, the two-layer film is omitted, and the production cost and the product cost are reduced. (2) Using hot-melt adhesive cold-rolling composite processing technology, color-printed film aluminum-plated rice packaging bag is firm and durable without cracking. Sovereignty item 1. A color printing film aluminized rice packaging bag composite layer and its processing technology, which is characterized in that first, a layer of color-printed PET color printing film is directly plated with aluminum to make a PET color printing aluminized film 5, and then this The layer PET color printing aluminized film 5 is processed into a color printing film aluminized rice packaging bag composite layer by hot melt adhesive and another layer of polypropylene woven bag layer 4 by a compound machine cold rolling and compounding.
