Amcor plc announced on June 10, 2025, that it has achieved significant material savings in its ongoing partnership with skincare brand Bulldog through the lightweighting of flexible tubes. A 16.67% reduction in the wall thickness of each tube sleeve for 50mm diameter flexible tubes is expected to save approximately 8.5 metric tonnes of plastic annually.
This modification, a result of close collaboration between Amcor and Bulldog, ensures that squeezability and consumer experience are not compromised, and the redesigned lighter-weight tube maintains high print and leak-test quality. The new tube sleeve is fully compatible with existing caps and shoulders, preventing disruption to the filling process.
In addition to lightweighting, Amcor increased the amount of post-consumer recycled (PCR) plastic used within the complete tube to over 62%. Bulldog has also utilized certified sugarcane from Amcor for its virgin material since 2017, further reducing reliance on fossil fuels.
