New low-cost manufacturing process for food packaging

02 July 2018

Researchers have developed a large-scale manufacturing process that may change the way some grocery store foods are packaged. The team created a manufacturing process using cellulose nanocrystals (CNCs) as advanced barrier coatings for food packaging. CNCs are an alternative renewable raw material derived from abundant resources such as wood and plants. They have properties including nontoxicity, biodegradability, high specific strength, high thermal conductivity and optical transparency, all of which make them excellent components for advanced food packaging. The technology also offers excellent optical, thermal and mechanical properties (News Release Purdue University, 26 June 2018).
