Researchers from the VTT Technical Research Centre of Finland have developed a transparent cellulose film for food packaging applications.
In a bid to produce plastic film that is not hard to recycle — as is the case with oil-based plastic films — the team turned to recrystallized cellulose, which is an organic compound.
The result is a transparent film that is reportedly bio-based and biodegradable, thereby solving the challenge of recycling the material.
“We can produce transparent and flexible cellulose film. The consumer cannot distinguish between the crystal-clear material and traditional oil-based plastic. Cellulose film can resist dampness, but in nature it disappears as completely as a sheet of paper does. The product is bio-based and biodegradable,” said VTT research professor Ali Harlin.
