A package insert includes a container formed with one or more polymers mixed with a bio-active agent, an agent operative to increase a hydrophilic property of the mix, and a binder. The mix fosters the growth of a layer of microorganisms and a microenvironment in which biodegradation is accelerated, when the container is placed in an active microbial environment, such as a landfill, where appropriate microorganism are commonly found. The container is filled with an unset gel, using standard industrial bottle handling and filling equipment. The gel is composed of a cellulosic material mixed with water, and functions as a phase-change material, absorbing heat at a slow rate and thereby providing cooling for an extended period. After filling, the gel becomes set and the container may be filled, leaving space for expansion, and the container may then be frozen. After freezing, the container and frozen contents are placed into a package to maintain a desired temperature within the package for an extended period. |
