1. A method of making a package comprising:
forming a moisture barrier coated paper material, wherein the moisture barrier coated paper material comprises: a paper-based substrate, a first polymer coating, a second polymer coating, a third polymer coating, and a hydraulic encapsulation layer of microencapsulated humectants or a microencapsulated aqueous-based solution disposed at, at least one of between the first polymer coating and the second polymer coating or between the second polymer coating and the third polymer coating the first polymer coating, the second polymer coating, and the third polymer coating applied over a first side of the paper-based substrate, the first polymer coating, the second polymer coating, and the third polymer coating providing a barrier for moisture and air exchange through the moisture barrier coated paper material, the first polymer coating, the second polymer coating, and the third polymer coating providing heat and pressure sealability capabilities to the moisture barrier coated paper material;
cutting a packaging blank from the moisture barrier coated paper material;
folding the packaging blank into the package; and
sealing the package by providing heat and pressure to overlapped portions of the moisture barrier coated paper material.
