A Novel Approach to Clear Barrier on Packaging Films
Howard Kravitz, CEO Tel: , ext 302 NanoPack Inc.

NanoPack Background Business Materials science Location Wayne, PA
Founding date Commercial late 2008 Employees *0.5 2
3
Materials Science Company
Singularize particles in a solubilized resin that is printed on flexible films. Goal: barrier to maintain shelf life 3
4
Replaces traditional materials
Standard materials Polyvinylidene chloride EVOH co-ex PVOH Glassy coatings SiOx AlOx 4

7
Coating Structure 30-40 layers of platelets 0.3µ 7
8
Choice of Resin is Important
Goal: Good barrier resin gets better with added tortuous path. 8
9
Good Barrier Resins Low* loading of platelets
Barrier improved by orders of magnitude Excellent clarity Destruct bond strengths * Less than 10% platelet loading 9
10
Choice of Clay is Important
11
11
Choice of Vermiculite is Important
Surface Charge is Key to Platelet Singularity 12
12
= NanoPack IP Choice of Vermiculite is Important
Singularity in solution requires proprietary chemistry = NanoPack IP 13
13
SEM: NanoSeal on Flexible Film
14
14
Another Feature of Vermiculite
Aroma Barrier 15
15
Application of NanoSeal
Barrier Film film Coating film Drying Dry barrier coating Gravure application 16
16
Oxygen Barrier Better Good PVdC (“saran”) EVOH co-ex PVOH 0.3µ 0.6µ 17
17
Oxygen Barrier Note 1: %RH inside of 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 0% when external RH is 0%; %RH inside of package @ 50% when external RH is ≥50%. 19
