\”Vitalis stress lines bottle design\” by Vetroelite, image/information source: Vetroelite
This Vitalis PET bottle features a distinctive stress line design that optimizes material usage while maintaining structural strength. The vertical stress lines—visible as subtle ridges or reinforcements along the bottle\’s body—distribute pressure evenly, allowing for thinner walls without compromising stackability or burst resistance.
Design Benefits
These stress lines reduce PET material by up to 15-20% compared to standard smooth bottles, cutting production costs and environmental impact through less plastic per unit. They also enhance grip and aesthetics, supporting Vitalis\’s sustainability push with RPET variants.
Material Savings
The lightweighting via stress lines aligns with industry trends, where similar designs in 1.5L bottles save around 10-15 grams of PET per bottle, promoting recyclability and lower carbon footprints during manufacturing. This is especially relevant for eco-focused brands like Vitalis from Super Bock Group.
