Sustainable biodegradable coatings for food packaging: challenges and opportunities

“…Coating methods include melt-extrusion, solution coating, dispersion coating and lamination, 173,178 of which extrusion coating is the most industrially established one. The preponderance of extrusion coating is due to (1) continuous proces-sing, (2) forming uniform coatings, (3) negligible pinholes/ cracks, (4) solvent-free application.…”

“…Therefore, it is often coated or blended with petro-based materials to fulfill the packaging requirements; 7 however, this excludes such packaging from biodegradability or repulpability. 173 Therefore, investment in the PHA-coated paper industry as well as using PHAs in biocomposite materials can help to widen PHA applications and reduce their costs.…”

Inspiring engineers

“…Professor Yu was one of my Ph. Ratto's research contributed to the design and improvement of the Meal Ready-to-Eat ration packaging, which have stringent requirements to assure performance in the field 8 . Her team developed melt-extrudable multilayer plastic films made from polymer structures which exhibit a high-barrier performance 9 .…”
