Recent progress in PBAT-based films and food packaging applications: A mini-review

Area of Science:

• Materials Science
• Polymer Science
• Food Science

Background:

• Bioplastics, such as polybutylene adipate co-terephthalate (PBAT), are emerging as sustainable alternatives to conventional non-biodegradable plastics.
• PBAT is widely used for flexible packaging films due to its inherent flexibility, though its strength can be a limitation.

Purpose of the Study:

• To review recent advancements in polybutylene adipate co-terephthalate (PBAT)-based films.
• To explore the application of these films in active food packaging, focusing on property enhancement and functionality.

Main Methods:

• The review synthesizes information on various PBAT film fabrication techniques.
• It comprehensively discusses the physical, functional, and biodegradability properties of modified PBAT films.

Main Results:

• Blending PBAT with fillers/polymers significantly enhances film strength.
• Incorporating bioactive functional fillers improves the overall functionality of PBAT films.
• PBAT-based active packaging films demonstrate potential for protecting food and extending shelf life.

Conclusions:

• PBAT-based functional films are a viable, eco-friendly alternative to petrochemical-based plastics for active food packaging.
• Further research into PBAT-based biodegradable active food packaging is encouraged to leverage its full potential.
