The latest technology trend of polylactic acid in packaging application (table)

as a biodegradable material, polylactic acid is increasingly favored by developers in the packaging field because of its non-toxic, non irritating, high strength, easy processing and molding, and excellent biocompatibility. In recent years, many new technologies have appeared in the packaging application of polylactic acid. On the basis of literature search, the author screened and sorted out the new technology in this field in recent three years, with a machine weight of 70kg, for the reference of relevant R & D personnel in China. 1、 New technology of using inorganic or non polymer organics as ingredients in preparation

c08k-005/11 [2] organic ingredients using acyclic polycarboxylic acid esters c08k-009/00 [1] using pretreated ingredients c08k-003/40 [1] using glass ingredients c08k-005/20 [1] using carboxylic amide ingredients c08k-007/14 [1] using glass ingredients c08k-009/06 [1] using pretreated silicon containing compounds

II New technology of plastic molding or connection
