Development of flexible packaging based on nanocomposites of biodegradable polymers and crystalline cellulose nanocrystals (CCN)

PROJECT DETAILS:

Single-use plastics are a major environmental problem. Biodegradable/compostable polymers offer a sustainable solution, but their performances are currently insufficient and their processing difficult, making their adoption challenging for many plastics converters.

The project will consist of developing methods for dispersing cellulose nanocrystals, as nano-reinforcements, in various bioplastics such as polybutylene adipate terephthalate and polybutylene succinate, for film applications. Preliminary work has shown an improvement in processing parameters, such as crystallization kinetics and polymer viscosity, increasing production rates. In addition, due to their nanometric size, high aspect ratio and highly crystalline structure, cellulose nanocrystals also improve the mechanical performance of fils, such as tensile strength and tear resistance. Barrier properties, such as oxygen and grease, are also expected to be improved based on Anomera’s experience with coatings.

The project results will lead to new markets for Anomera, which will require higher staff for the company’s Montreal office and its Témiscaming production plant to develop, scale up and distribute the new materials. Quebec plastics converters have already expressed interest in the project results for the development of new biodegradable plastics. The project is expected to increase sales of these products in Quebec. The project will train one postdoctoral fellow.
