Latest Patents

One of Jung-Min Sohn's latest patents is a packaging film that includes a lactide copolymer. This invention addresses the issues of pollution and toxicity while maintaining good flexibility and excellent properties such as mechanical strength, transparency, and processability. It is particularly suitable for food packaging applications. The packaging film comprises a lactide copolymer with two or more specific block copolymerized repeating units. The hard segments of polylactide repeating units are connected to both ends of the soft segments of polyether polyol repeating units. These block copolymerized repeating units are linked through urethane connecting groups derived from a polyvalent isocyanate compound, which has an average equivalent of isocyanate groups per molecule that is more than 2 and less than 3.
