The Catechin Green Tea is a type of cold brew green tea advanced by special technology to extract aroma and high potency catechins with just 30 seconds. Considering the Catechin Green Tea not only brings out an excellent flavor but boosts metabolism, we wished to create a unique and functional impression on its packaging design. Impressed by its fresh taste, we used a bright and white background to reflect its light character. Product values with scientific support are featured with words, numbers, and tables at the front of the package. The illustration with abstract green strips and golden dots conveys two concepts : A. Layers of tea flavor, ripple, and the remarkable efficacy of catechin. B. Farmers with bamboo hats working among rows of tea tree. With the request to combine dietary habits and records of metabolism measurement, we put a measurement table at the back of the package, so customers can be reminded to keep a better metabolic rate. To present its natural characteristic and brand personality, we used the one-side coated paper but printed it reversely to avoid excessive glossy printing or commercialization.
