Many tea bags are made with polypropylene, a type of plastic used for sealing and heat-resistance. This plastic can release microplastics and potentially harmful chemicals like BPA and phthalates into the beverage during brewing, especially at higher temperatures. These substances can then be ingested, raising concerns about potential human health risks. The presence of plastic in tea bags also poses environmental problems, contributing to microplastic pollution in landfills and waterways, where they can harm aquatic life.
Understanding the potential health and environmental impact of plastic in tea bags is crucial for informed consumer choices. The increasing awareness of microplastic pollution and its potential consequences underscores the need for greater transparency regarding the materials used in food packaging. The demand for more sustainable alternatives is driving innovation in tea bag production, leading to the development of biodegradable and plastic-free options.
