Abstract:
1. A packaging system having a peelable seal section, the peelable seal section including a first sealing layer and a second sealing layer such that the first sealing layer contacts the second sealing layer to form a peelable seal, the first sealing layer includes: a thermoplastic polymer including ethylene vinyl acetate and linear low-density polyethylene; an organoclay dispersed within the thermoplastic polymer, the organoclay including a plurality of particles having at least one spatial dimension less than 200 nm; and calcium carbonate dispersed within the thermoplastic polymer, the calcium carbonate including a plurality of particles having an average diameter of 0.5 microns to 20 microns, the organoclay being present in an amount from 5 weight % to 20 weight % of the combined weight of the thermoplastic polymer and the organoclay and the calcium carbonate, and the calcium carbonate being present in an amount from 6 weight % to 25 weight % of the combined weight of the thermoplastic polymer and the organoclay and the calcium carbonate, the peelable seal having a peel force between 0.5 lbs and 5 lbs per inch of sealing width.
