Move beyond conventional plastic.
Preserve the experience by design.

Nacrealia is designed around what a cold-cup system must retain—clarity, secure closure and familiar store handling—while shifting the structural body to regenerated cellulose and applying a predominantly inorganic SiOₓ barrier after forming.

Nacrealia transparent cold-cup design visualisation — Design visualisation. Appearance and performance remain subject to the defined prototype and validation programme.

THE MATERIAL PROPOSITION

A simpler architecture with distinct jobs.

The formed cellulose shell provides shape and optical presentation. A thin SiOₓ layer is applied to the internal surface after forming to address liquid and vapour exposure without turning the cup into a thick polymer laminate. ShellLock™ then treats lid retention as a geometric engineering problem.

REFERENCE OBJECTS · PHOTOGRAPHED FROM THE MEDIA LIBRARY

Design from the service interface backwards.

These photographs document the incumbent customer and store interface. They are design references—not Nacrealia prototypes—and help define what the new system must preserve while changing the material architecture.

Photographed transparent cold-cup lid used as a closure reference — **Closure clarity**A visible, intuitive interface with positive engagement and controlled drinking geometry.

Photographed transparent cold cup used as a handling reference — **Familiar handling**Transparency, stackability, grip and fast assembly remain part of the performance brief.

IMPACT HAS FOUR AUDIENCES

Useful change must work across the whole system.

01 · CUSTOMER

Keep the ritual

Protect beverage visibility, neutral sensory performance and a confident drinking experience.

02 · STORE

Respect the workflow

Design for rapid lid application, nesting, handling and cold-service reliability.

03 · SUPPLY

Engineer a route to scale

Use formed-sheet conversion logic, controlled drying and post-forming barrier deposition.

04 · RECOVERY

Verify the destination

Test the complete article in relevant collection and fibre-recovery scenarios before making claims.

EVIDENCE BEFORE CLAIMS

Measure the impact we intend to create.

Nacrealia’s impact case will be built from verified mass, process energy, yield, logistics and recovery data—not from the appearance of the concept.

Material ledgerCup and lid mass, cellulose source, SiOₓ loading and auxiliary materials.

Process boundaryDissolution, sheet formation, forming, constrained drying and barrier deposition.

Yield and logisticsConversion scrap, nesting efficiency, transport density and store handling.

Destination reviewRepulpability and other recovery routes assessed for the finished article.

Claim discipline: carbon reduction, recyclability, compostability and industrial readiness will only be stated when supported by the corresponding tests and system boundary.

A CREDIBLE PATH TO SCALE

Make the decision gates visible.

Optical quality, cold-liquid hold, closure retention, sensory neutrality, food-contact safety and manufacturing compatibility form the evidence chain. The validation programme turns ambition into an investable sequence.
