Starch-based edible packaging: rheological, thermal, mechanical, microstructural, and barrier properties – a review
Summary
This review examines starch-based edible packaging as an alternative to conventional plastic packaging, looking at how oils and nanoparticles can improve these biodegradable films. While not directly about microplastic health effects, replacing traditional plastic packaging with edible, plant-based materials could significantly reduce the amount of plastic waste that breaks down into microplastics. These alternatives could help decrease human exposure to microplastics from food packaging.
The microstructures of starch-based edible films are shown in the following micrographs. A well-defined distribution of edible oils and cellulose nanoparticles on the starch surface can be clearly visualized.

Recent advancements in alginate-based films for active food packaging applications
This review covers advances in alginate-based films as alternatives to plastic food packaging, which could help reduce the amount of plastic entering the environment. While not directly about microplastic health effects, developing effective biodegradable packaging is one strategy to reduce the flow of plastics that eventually break down into microplastics. These plant-based films could help decrease the overall microplastic burden in food and the environment.
Preparation and characterization of edible film from Barnyard millet starch
Researchers developed edible films from barnyard millet starch as a biodegradable alternative to synthetic plastic food packaging.

A Comprehensive Review of Biodegradable Polymer-Based Films and Coatings and Their Food Packaging Applications
This review covers the development of biodegradable polymer-based films and coatings as alternatives to conventional plastic food packaging. While these bio-based materials reduce long-term environmental pollution, the review notes that they can still break down into microplastic particles under certain conditions. The shift to biodegradable packaging may reduce but not eliminate the food packaging contribution to microplastic pollution and human exposure.
Materials
This paper reviews advances in nanocomposite and biopolymer-based food packaging materials, noting that microplastic pollution has been detected globally and is a recognized threat to ecosystem and human health. It briefly contextualises microplastics as a motivation for developing biodegradable packaging alternatives, though the primary focus is materials science rather than microplastics research per se.
A Review of Recent Developments in Edible Films and Coatings-Focus on Whey-Based Materials
This review examines how edible films and coatings made from whey protein could serve as biodegradable alternatives to petroleum-based plastic packaging for food. By replacing conventional plastic wrapping, these materials could help reduce microplastic generation from food packaging, which is a significant source of human microplastic exposure.
