The Development of a Single-Screw Extrusion Process for Production of Low Density Biodegradable PLA Foam for Thermoformed Food Packaging Applications (PLA-FOAM)
Date du début: 1 oct. 2009, Date de fin: 30 sept. 2011,
"450 k t p.a. of foamed polymer packaging (mainly expanded polystyrene, EPS) is consumed in the EU with 34% (150 k t p.a.) used for food packaging. Foam packaging is an essential part of the food processing and transport process to prevent damage and spoilage. However, they are made from synthetic polymers and have low density (50 kg/m3) which makes them difficult to recycle economically. Thus, th ...
