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

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
