A Novel Approach to Clear Barrier on Packaging Films Howard Kravitz, CEO Tel: 484-367-7015, ext 302 hkravitz88@nanopackinc.com NanoPack Inc.

NanoPack Background Business Materials science Location Wayne, PA Founding date 2004 Commercial late 2008 Employees 4 + 2*0.5 2

Materials Science Company Singularize particles in a solubilized resin that is printed on flexible films. Goal: barrier to maintain shelf life 3

Replaces traditional materials Standard materials Polyvinylidene chloride EVOH co-ex PVOH Glassy coatings SiOx AlOx 4

5

Packaging Structure Structural Film Barrier Adhesive Ink Sealant Film 6

Coating Structure 30-40 layers of platelets 0.3µ 7

Choice of Resin is Important Goal: Good barrier resin gets better with added tortuous path. 8

Good Barrier Resins Low* loading of platelets Barrier improved by orders of magnitude Excellent clarity Destruct bond strengths * Less than 10% platelet loading 9

Choice of Clay is Important 11

Choice of Vermiculite is Important Surface Charge is Key to Platelet Singularity 12

= NanoPack IP Choice of Vermiculite is Important Singularity in solution requires proprietary chemistry = NanoPack IP 13

SEM: NanoSeal on Flexible Film 14

Another Feature of Vermiculite Aroma Barrier 15

Application of NanoSeal Barrier Film film Coating film Drying Dry barrier coating Gravure application 16

Oxygen Barrier Better Good PVdC (“saran”) EVOH co-ex PVOH 0.3µ 0.6µ 17

Oxygen Barrier Note 1: %RH inside of package @ 0% when external RH is 0%; %RH inside of package @ 50% when external RH is ≥50%. 18

Oxygen Barrier - continued Note 1: %RH inside of package @ 0% when external RH is 0%; %RH inside of package @ 50% when external RH is ≥50%. 19
