Oxo-Biodegradable Plastic Packaging: Overview and Function
Oxo-biodegradable plastic packaging is a type of plastic designed to undergo accelerated degradation through exposure to oxygen, light, or heat, followed by microbial decomposition. It is used as a means to reduce the persistence of plastic waste in the environment.
Composition and Mechanism : Oxo-biodegradable plastics are typically made from conventional polymers, such as polyethylene, with additives that promote oxidative breakdown. These additives cause the plastic to fragment into smaller pieces, which can then be further decomposed by microorganisms over time.
Applications : This type of packaging is used for bags, wraps, and single-use containers. It functions similarly to standard plastics during handling, storage, and transport, while providing a pathway for gradual environmental degradation after disposal.
Considerations : The rate and completeness of degradation depend on environmental conditions such as temperature, UV exposure, and presence of microbes. Proper disposal and management are essential to avoid accumulation of microplastics.
Conclusion : Oxo-biodegradable plastic packaging is designed to break down more readily than conventional plastics under specific conditions. Its application focuses on environmental decomposition processes rather than altering the functional or mechanical properties of the packaging.
