When a plastic lid is heated from a hot beverage it emits a scent of plastic. Even a hint of plastic odor will adversely affect the coffee. The problem is hot beverages create thermal waves that hit the coffee lid and cause it to release this undesirable smell.
Since taste is 80% aroma and because smell is our most powerful sense, this is a real problem for companies that sell coffee out of cups with plastic lids.
To solve this problem, Hong Kong-based MINT has introduced a plastic coffee cup lid with a coffee smell embedded in the lid.
According to the company, the the Aroma Lid overcomes all plastic smell and taste issues â€“ making it the ‘best tasting’ coffee lid in the world.
