Plantable Tags from Recycled Pulp

Plantable tags made from recycled paper with embedded sunflower seeds were developed as a sustainable alternative to conventional tags. This research aimed to produce plantable tags that can truly grow, and to evaluate and compare the growth rate and germination rate of sunflower seeds embedded in tags made from different paper weights and tag structures. In this experiment, recycled paper was used to form hand sheet paper (30 and 50 gram), then cut into 6×9 cm tags. Two assembly tags, adhesive bonding and told and insert, were filled with five sunflower seeds and then measured for their seed germination. The labels were planted in composted soil under controlled humidity and light, and seed growth was measured every 3 days over 30 days. In addition, adhesive tags due to their better water absorption achieved higher germination rates than adhesive tags. These findings confirmed that plantable tags were a simple, eco-friendly solution for sustainable packaging. Notably, the 50 gram adhesive tags exhibited the highest germination performance over the 30 day period
