Alternative food packaging materials are needed to overcome this effect and reduce plastic use.
In addition, the incorporation of nanoparticles into biopolymers can lead to the development of materials with better physical-mechanical properties [6].

Pseudo static experiment program Material properties.
The areas of various materials surrounded by hysteresis loops enlarge gradually with the increase of loading displacement, especially in the later stage of loading, the area increase rapidly, which indicate that the internal stiffness degenerated obviously, and the equivalent damping get larger gradually.

Austenitic materials e.g.
On one hand they are single-phase materials and on the other hand it is possible to determine the grain size immediately after heat treatment.
Even after application the welding cycles the grain didn’t coarse significantly compared to materials S304H [8], TP347HFG [9].
