Turning the Wonders of Cellulose Nanocrystals into Advanced Materials

Dovy Segev – CEOOctober 2015

The Need – Agricultural Films

• Transparency• Heat (IR blocking)• Anti insects (UV blocking)• Anti mist• Anti drip

Visible energy from the sun passes through the glass and heats the ground

IR heat energy: released from the ground, reflected from the glass most of it trapped inside

The Need – Agricultural films

• Lower transparency• Low Heat (IR blocking)• No UV blocking• Anti mist • Anti drip

Short periods only

Additives are not a solution- looking for specialty coatings

The Need – Food Packaging

• Transparency• UV blocking• Oxygen barrier (OTR)• Water vapor barrier (WVTR)• Excellent printability

Simple solutions with competitive pricing

Market Applications

Market focus: food packaging, agriculture, special paints & coatings

• Food packaging $235 billion (2012)¹

• Flexible food packaging: $110 billion (2012)²

• Agricultural films market: $11.7 billion (2020)³

• Aerospace coatings market: $2.9 billion (2019) ³1. Source: Flexible Packaging Association, BofA Merrill Lynch Global Research2. Source: Ernst& Young, A Global Perspective, Exploring the Dynamics of the Flexible Packaging marketplace, Feb 20123. Source:Markets & MArkets

Nanoparticles Challenge - Valentis Solution

• NPs (glass, metals, and semiconductor materials) = potential to enhance different materials

• Problem: tendency to stick together, must obtain even dispersion to maintain their impact and effectivity

To prevent this agglomeration during processing, Valentis utilizes CNC as an NP carrier

• Self-assembly• Strong• Transparent• Thin

• Gas barrier• Spectral control• Texture control• Anti bacterial
