Rightweighting

This is where precision meets sustainability! As opposed to ‘lightweighting’, ‘rightweighting’ is about much more than just reducing the weight of packaging.

At Vetropack, we’re taking a holistic approach to optimising glass containers – with dual goals: Lighter, but more stable; fewer resources, but higher performance: packaging manufacturers are increasingly confronted with demands like these. As a natural raw material that is infinitely recyclable, there’s no doubt that glass offers clear advantages over other materials when it comes to sustainability. But like every other sector, the glass industry is aiming to improve resource efficiency – so manufacturers are searching for more ways to reduce material usage without compromising the performance of glass packaging.

With rightweighting, we address all requirements for the value chain – including aesthetics, branding, product protection, performance criteria such as strength and quality, fillers’ requirements, technical feasibility, and environmental considerations. Once all these factors are taken into account, the ratio of weight to performance has to be right.

Three different factors are driving rightweighting ahead at present.

Sustainability: which focuses particularly on each container’s energy footprint.
Cost: less material per unit means money saved.
Innovation: we keep a very close watch on the market.
