Plasma treatment improves durability of plant-based packaging films
Researchers at North Carolina State University published a study in Applied Surface Science on how dielectric barrier discharge plasma enhances moisture resistance in cellulosic nanofibril films.
New coating reduces water absorption
Scientists applied protective layers to the surface of cellulosic nanofibril films using advanced plasma technology. One specific treatment lowered liquid water absorption in these films to less than one percent. This process creates a functional barrier that helps renewable materials compete with traditional plastic wraps.
Control over moisture interaction
The study demonstrates that dielectric barrier discharge plasma allows precise control over how natural fibers interact with water vapor. Nathalie Lavoine noted this strategy turns plant and tree fibers into water-resistant packaging materials. The findings suggest society can move closer to replacing everyday plastic with biodegradable alternatives.
Study publication details
The work appears in the journal Applied Surface Science according to the report from physorg. Researchers used this method to improve the durability of packaging derived from renewable biomass. The results offer a scalable solution for reducing the environmental footprint of plastic waste.
