Active Physical Preservation &
Sub-Micron Gas Equilibrium
Zero chemical residues. Zero toxicity. We utilize advanced polymer physics and nano-structured active media to continuously suppress produce respiration and catalyze ethylene decomposition.
The 4 Pillars of Polymer Physics Preservation
How our multi-layer film active structure achieves exponential shelf-life extension.
Micro-Porous Gas Equilibrium (MAP)
By precisely controlling the oxygen ($O_2$) and carbon dioxide ($CO_2$) transmission rates, our material creates an optimal equilibrium atmosphere inside the package, slowing down cellular respiration without inducing anaerobic fermentation.
Active Ethylene Scavenging
Proprietary nano-catalysts embedded directly into the polymer matrix trap and break down ethylene gas ($C_2H_4$) produced by climacteric fruits, halting premature softening and senescence at the molecular level.
Condensation & Humidity Management
Nano-surface coating technology prevents the formation of condensation water droplets. By converting free moisture into a micro-thin, highly transparent film layer, mold growth (*Botrytis cinerea*) is eliminated while preserving 90-95% RH.
Physical Microbial Barrier
The non-porous outer barrier combined with non-leaching physical active structure prevents spore adherence and cross-contamination during long-distance maritime transport without relying on chemical fungicides.
Empirical Lab Testing & Performance Data
