Application of Green Environmentally Friendly Materials in Food Packaging

Abstract

With social development, requirements on the spiritual and material life have increased. However, some environmental issues appear, for example, in food packaging. Application of environment-friendly materials in food packaging has been more and more attractive. This study analyses the characteristics of degradable food packaging material and the existing problems, proposes the manufacturing of food packaging with poly(lactic acid)/ nanocrystalline cellulose composite material, tests its thermal and mechanical properties, and applies it to the design of food packaging. The results demonstrate that the thermal and mechanical properties of the material could satisfy the requirements of food packaging and that the material is applicable to the design of food packaging in the future. This work provides a reference for the application of green, environment-friendly materials in the design of food packaging.

Enhanced electrical and thermal properties of semi-conductive PANI-CNCs with surface modified CNCs

“…1,12 However, PANI is brittle and insoluble in organic solvents, which results in poor processability and limits its application. Although researchers have focused on developing a suitable ller to modify PANI properties for use in devices such as corrosion inhibiter, 13 supercapacitors, 14,15 thermoelectric generators, 16,17 and gas/vapor sensors, 18 the degradation in mechanical performances of PANI-based composites due to the aggregation of particles and PANI brittleness remains a problem. 19 Cellulose derivatives are ideal materials for reinforcing 20 composites because of their renewability, sustainability, and biodegradability.…”
