A tea bag, or the compound teabag, is a small, porous, sealed bag or packet, typically containing tea leaves or the leaves of other herbs, which is immersed in water to steep and make an infusion.
Tea bags are generally made from paper and polypropylene. Those sold in the UK, for example, are 70 to 80 per cent biodegradable, according to a consumer rights watchdog.[1]
The polypropylene is used in heat sealing the bags. On the European continent, a vegetable gum is often used instead - such bags can be 100 percent biodegradable .[1]
