Optimizing Closure Designs to Achieve Sustainability Targets
- November 22nd, 2022
As circularity and carbon reduction dominate sustainability agendas, beverage brands seek packaging innovations that balance performance with environmental impacts. For plastic closures, lightweighting and standardized neck finishes offer immediate opportunities to improve resource efficiency. By minimizing material usage while maintaining structural integrity, next-generation closure systems exhibit enhanced sustainability profiles.
Through advanced modeling techniques, closure engineers now pursue weight reduction at the component level. By precision sculpting and geometrically optimizing discrete features, ultralight designs emerge without compromising sealing, stacking or capping. This iterative approach to lightweighting reduces resin requirements beyond conventional manufacturing limits.
Standardized neck finishes complement lightweighting, enabling additional material and carbon savings. New designs like 26/22 provide lighter weight options to replace legacy finishes and satisfy demands for performance and compatibility while aligning with sustainability targets. Tether-ready or non-tethered variants cater to upcoming tether mandates, future-proofing investments. Standardization also streamlines supply chains, amplifying sustainability through systemic efficiencies.
For brand owners, embracing lightweight and standardized closures represents a straightforward sustainability play. With turnkey solutions available, transitioning to next-generation designs brings immediate resin and emissions reductions. On a collective scale, widespread lightweighting adoption could save billions of pounds of plastic annually, underscoring systemic potential.
While circularity challenges remain multifaceted, optimizing closure hardware constitutes an easy win. By expending less to achieve the same functionality, lightweight and standardized closures epitomize the essence of sustainable design. For both aspirational eco-brands and pragmatists seeking progress, embracing these technologies accelerates the sustainability journey.
