Packaging Design Eco Lettuce Multifunctional Food Packaging by Ning Sun Eco Lettuce Package is a food package that also serves as a growing container for lettuce. Leaf lettuce continues to produce new leaves when watered regularly after trimming. The leaves are eaten and the roots are kept. The package is then turned over, water and the wrapping paper are added, and the plant grows through the holes. A second harvest is possible within several weeks. The wrapping paper is made of recycled paper and supplies nutrition. The container is made of PLA, a plant starch based plastic, and is shaped by vacuum forming.
