Under the trend of low-carbon vision in the food package industry, an analyzed and completed method of low-carbon package based on life circle of product was introduced into food packages. During the study, a low-carbon concept was raised first, coupled with the life cycle vision, and a systematic low-carbon model was also put forward at the point of product, which is helpful in the later process of how to devise a total low-carbon procedure for food package. Finally, a environmental-friendly dishware package was adopted as a example to demonstrate the practicability and efficacy of both the specific concept and model in the practice of package design.
