Packaging Design Droplet-shaped lightweight bottle Lightweight-PET-Bottle by Stephanie Wunderlich The droplet-shaped PET bottle holds 200ml, and with a weight of just 4.4gr is extremely light. It can be produced using a standard blow-moulding machine that is also suitable for lightweight formats. Moreover, the container offers an option for pressurising it with nitrogen after filling, thus stabilising it for storage and transportation. In terms of dress, too, the PET bottle offers abundant design versatility: different labelling processes enable different designs to be achieved. This means the beverage producers can market the bottle in different price segments and retailing structures.
