All Tick Tock teabags are fully plant-based and biodegradable, and most importantly, free from polypropylene and all other petrochemical plastics. Because they are fully biodegradable, you can put these teabags in your Food Waste bin for composting by your local council. These teabags were the result of months of research and testing, and as a small family company we are going to constantly work to improve our packaging further.
