Iranian scientists have developed new nanobiocomposite films that can be used for the packaging of food products.
The nanobiocomposite films have been developed using a solvent method based on the formulation of glycerol and sodium montmorillonite. They can be used for food packaging and also degrade in soil and enzyme media.
During the first stage of the study, the researchers investigated the polymeric properties of the films such as tension strength, transparency, and contact angle.
In the second stage, researchers studied food packaging properties such as light elimination and antimicrobial properties of the films. Environmental properties were investigated in the final stage of the study.
The mechanical properties of the nanobiocompositefilms have been modified and the impact of sodium montmorillonite particles in the process was less than compared to the glycerol in the minimisation of mechanical properties.
Transparency as well as hydrophilicity of the samples is said to increase as the glycerol amount increases. They also decrease when nanoparticles exist.
The results noted that the polymeric films can be used in the packaging of dry food products or in primary packaging. The films can also be used in the secondary packaging of food products in order to avoid the humidity impact of the environment.
