BIOMIMETIC REGENERATED-CELLULOSE CUP SYSTEM
Transparency,
shaped by nature.
Nacrealia is a transparent, plastic-free cold-cup and lid concept inspired by nacre: a layered architecture that separates clarity, strength, containment and closure into functions that can be engineered independently.
See the beverage
Finished-cup clarity is a primary performance requirement, not a cosmetic afterthought.
Trust the closure
A reinforced rolled rim and CurlLock™ geometry target secure engagement without a highly elastic plastic snap-fit.
Preserve the ritual
Familiar handling, drinking, stacking and service speed remain part of the engineering brief.
01
Structure
Oriented regenerated cellulose provides the transparent load-bearing body.
02
Containment
A minimal gradient barrier targets water, oil and aroma resistance without becoming a thick plastic-like layer.
03
Closure
CurlLock™ uses geometric interference beneath the reinforced rim to reduce strain and cracking.
04
Drinking safety
A clear raised lid profile and controlled aperture are designed to reduce splash while preserving visibility.
01 — Optical clarity
02 — 24-hour cold containment
03 — Sensory neutrality
04 — Closure, splash and drop integrity
05 — Migration and food-contact safety
06 — Conversion speed and line compatibility
