Addressing the ecological crisis of excessive packaging, this design introduces "Ephemeral Packaging" to synchronize a product’s lifespan with its wrapping. By engineering bioplastics from gelatin, carrageenan, and corn starch, we developed dissolvable soap cases, transparent floral sachets, and upcycled tea-waste packaging . This approach redefines "waste," establishing a zero-trace cycle where packaging seamlessly returns to the natural environment.
