Modified clays used to create transparent films with strong barrier, UV properties


The new Industrial Coating and Packaging (ICAP) consortium will use modified clay plastic technology to help food stay fresher.

Singapore-based Agency for Science, Technology and Research (A*STAR) stated the consortium is set up by its Institute of Materials Research and Engineering (IMRE) group and industry partners.

In its first industry-themed project, the new ICAP consortium will develop transparent plastics that can better protect foods and medicines from oxidation and keep them fresher for longer by blocking oxygen, moisture and UV rays.

To help develop this, ICAP will use IMRE's modified clay technology.

"Our technology is to incorporate plate-like clay into a polymer matrix, which is sandwiched between two plastic layers," an IMRE spokesperson told PlasticsToday. "This enhances the efficiency of the polymer against moisture and oxygen penetration/seepage. The UV blocking is from the metal oxide immobilized on the clay sheets."...
