Gentlebrand’s SmartWeighting balances sustainability and aesthetics

In an era where the beverage industry faces intense pressure to cut plastic usage, lightweighting has frequently come at a cost to premium brand identity.

Historically, ultra-light bottles have been synonymous with low-cost, flimsy packaging that compromises the consumer experience. However, a new design and development approach from packaging agency Gentlebrand, demonstrated via its new Minera still water bottle concept, aims to prove that material reduction can coexist with premium aesthetics.

Dubbed SmartWeighting, the method shifts the industry focus away from simply stripping material weight. Instead, it prioritises optimising how PET is distributed and expressed within a bottle’s structure. If successful in widespread industrial application, the approach could allow premium beverage producers to pursue aggressive environmental and economic targets without sacrificing their on-shelf presence.

Engineering meets aesthetics

The commercial potential of SmartWeighting lies in its solution to a long-standing market paradox: how to lightweight a container without it looking or feeling cheap. Gentlebrand developed the approach specifically to counter the industry challenge where lighter bottles inadvertently signal lower quality to consumers. By balancing weight optimisation with structural engineering and visual design, the company claims lighter bottles can retain a refined look and feel.

To achieve this with the Minera still water bottle, Gentlebrand partnered with Competek, an engineering firm specialising in beverage packaging. Together, they developed a design that alternates clean, minimalist areas with technical, functional elements that discreetly reinforce the bottle structure. Additionally, the team optimised the neck finish to reduce excess material while simultaneously improving handling and the user experience.

Andrea Rizzardi, director of Gentlebrand, explained the philosophy behind the project: “MINERA SmartWeighting allowed us to demonstrate that reducing weight does not have to mean making compromises. SmartWeighting focuses on how material is used, not simply how much, ensuring structural reliability, visual quality and brand positioning are preserved.”

Supply chain compatibility 

A key factor dictating the commercial viability of any new packaging technology is its ability to withstand the rigors of the existing supply chain. Gentlebrand states that the Minera project was engineered to guarantee strength and stability across every operational stage, from initial blowing and filling through to transport and storage. To ensure seamless industrial compatibility, development was supported through collaboration with international partners across the beverage supply chain.

The potential of the SmartWeighting approach is further enhanced by its integration with next-generation sustainable materials. The physical Minera bottle utilises a dual-material strategy:

• The body: produced using 100% BioPET supplied by UPM Biochemicals.
• The label: Uses UPM Raflatac Vanish PCR film, creating a “no-label look” that enhances visual purity and perceived quality while supporting overall recyclability.

For beverage producers, the business case for SmartWeighting spans both economic and environmental metrics. By integrating visual aesthetics, engineering, and material optimisation, the approach delivers tangible benefits across the supply chain, including reduced PET usage and improved logistics efficiency.

Looking ahead, Gentlebrand views the methodology as a template for the future of the sector, framing it as a system where smarter, more considered solutions support environmental and economic objectives while remaining aligned with brand identity.
