Introduction Non-destructive testing (NDT) of materials are commonly performed to identify, characterize, assess voids, defects and damage in materials [1].
The amount of energy lost through absorption depends upon the elastic properties of the material being tested [16] while loss due to scattering in materials also depends on the ratio of grain size and wavelength [6].
Moreover, it is possible due to the close association of the ultrasonic waves with the elastic and inelastic properties of the materials [17].

The properties of materials at this scale can be very different from conventional materials.
Most of the current applications of nanotechnology are in electronics, automation, super-materials, or life sciences such as pharmaceuticals and medicine.

Same as in the macromanufacturing, advanced materials play an increasingly important role in shaping of microparts.
The measured response depends on optical properties and thickness of individual materials.

The results of this research might have the opportunity to be used as packaging film materials in the future.
As such, packaging materials play a crucial role, but most of them are petroleum-based [1].
