Lightweighting a Package to Increase Performance and Meet Sustainability Goals
SC Johnson was experiencing problems with its 2L Windex® refill bottle. The grip wasn’t strong enough which would cause the bottle to buckle as it was lifted and tilted. Contents would gush out and spill during the refill process, creating problems for consumers. SC Johnson’s goals were to lightweight the package, improve package performance, and drive additional sustainability benefits.
PTI utilized predictive modeling to simulate the squeezing that occurred when the package was being picked up. The predictive modeling permitted multiple design iterations, eliminating the expense of cutting tooling, producing samples, and then testing the options.
This project was a great success because the client was willing to increase the weight of the package just to eliminate the core issue. PTI was able to avoid that and improve bottle design by reducing the weight significantly, but ensuring the final package was stronger than the previous design.
