PET Bottle Lightweighting Design
PET Bottle Lightweighting Design
PET bottle lightweighting reduces the gram weight of each bottle without sacrificing top-load, drop, and fill-line performance. iBottling's design service re-engineers preform and bottle geometry so material savings are realized within your existing filling and labeling equipment.
Every lightweighting study is validated against your bottle size, resin, and line conditions — we do not apply a generic weight target.
How the Lightweighting Study Works
We model base and sidewall geometry, review preform injection and stretch-blow settings, and confirm top-load and filling stability through sample runs. Recommendations are delivered as revised drawings and process parameters for your blow molder.
Where rPET content is part of your specification, we design the geometry to stay compatible with your recycled-material ratio.
