Testing and Characterization of Biodegradable Plastics
Polyethylene (PE), polypropylene (PP) and polystyrene (PS) , made from petroleum-based polymers, are not expensive and durable, so they are used in many plastic products. Recently, the environmental pollution problem caused by microplastics has become a global concern, and how to limit their impact on the environment is being discussed. In order to reduce plastic waste, the development of eco-friendly alternative materials is being promoted. As an alternative, biomass plastics and biodegradable plastics are becoming more widely available.
Biodegradable Plastics are plastics that are decomposed into low-molecular compounds by microorganisms in the environment. So they break down easily in nature, which is an opposite characteristic of petroleum-based plastics. They are recommended for single-use products. At this time, it is true they are inferior to petroleum-based plastics in the features of durability and functionality, so research and development of new materials is on going for a reliable solution.
Characterization of Biodegradable and Oxo-Biodegradable Plastic Bags
This application news describes the use of Fourier Transform Infrared spectrometry (FTIR), Differential Scanning Calorimeter (DSC) and Thermogravimetric Analyzer (TGA) for characterization of plastic bags, which are labelled either as oxo-biodegradable or biodegradable.
