Abstract
Biodegradable polymers are attracting scientific and industrial interest due to their eco-friendliness.
This increased their economic and environmental value.
However, brand owners, retailers, and customers must understand biodegradables packaging materials and their functions.
In this study, the packaging materials were characterized for their physical, mechanical, and water barrier properties.
Biodegradable packaging materials have the highest water vapor permeability (8.90- 11.05×10‑3 g day‑1 Pa‑1). The stamped paper tray with the three-layer plasticized NC-sorbitol substrate had the highest water vapor transmission rate (264.73 g day‑1). Cold storage conditions significantly (p<0.01) affected biodegradable material mechanical properties.
Compared to ambient, cold storage decreased tensile strength by 3.5%. The glued paper tray had the highest tensile strength compared to the stamped and pulped paper trays after storage in cold and ambient conditions.
Conventional packaging had a higher modulus than biodegradable packaging.
Biodegradable packaging had a broad absorption band from 3338.98 to 3200 cm‑1 in the Fourier Transformed Infrared (FTIR). The elementary composition of biodegradable packaging materials had the highest carbon atomic, 60.5% and weight, 39.01%, according to FTIR and energy dispersive X-ray results.
In conclusion, the inclusion of a plasticizer enhanced the mechanical qualities while lowering the water absorption.
These findings demonstrate that the potential use of biodegradable packaging materials offers a remedy for the environmental issue of excessive plastic usage.
This increased their economic and environmental value.
