Amcor, a global leader in developing and producing responsible packaging solutions<\/a>, has achieved significant material savings as part of its ongoing partnership with skincare brand Bulldog<\/a>, through the further lightweighting of its flexible tubes.<\/p>\n The 16.67% reduction in the wall thickness of each tube sleeve for the 50mm diameter flexible tubes used across a number of Bulldog products in 100ml and 150ml sizes, is expected to save approximately 8.5 metric tonnes of plastic annually.<\/p>\n The modification is the result of close collaboration between Amcor and Bulldog to further improve the sustainability attributes of Bulldog\u2019s products. Amcor<\/a> developed a series of rigorous trials to prove that the squeezability and consumer experience were not compromised by this change, and that the redesigned lighter-weight tube maintained the high-print and leak-test quality. The lighter-weight tube sleeve is fully compatible with the existing tube cap and shoulder, ensuring the filling process is not impacted.<\/p>\n In addition to the lightweighting, Amcor increased the amount of post-consumer recycled (PCR) plastic used within the complete tube to over 62%.<\/p>\n
