Abstract: The present invention includes processes and resulting structures for producing a modified polymer having interconnecting channels. The interconnecting channels act as controlled transmission passages through the polymer. A hydrophilic agent is blended into the polymer so that it is distributed within the polymer. In one embodiment, a releasing material is blended into the polymer so that the releasing material is distributed within the product. The product is solidified so that the hydrophilic agent forms passages in the product through which a desired composition is communicable to the releasing material that is entrained within the product. The solidified product may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.

Abstract: A barrier pack comprising a cover portion bonded to a base portion to form a sealed unit package capable of containing a product wherein the cover portion has at least one cavity and the base portion and/or cover portion has an absorbing agent material applied to the cavity and/or base portion.

Abstract: The present invention includes processes and resulting structures for producing a modified polymer having channels. The channels act a controlled transmission passages through the polymer. A polymer is caused to assume a molten state, typically by applying heat and melting the polymer. A channeling agent is blended then reacted into the polymer so that it is distributed within the polymer. In one embodiment, an absorbtion additive is then blended into the product so that the absorbtion additive is distributed within the product. The product is solidified so that the channeling agent forms passages in the product through which a desired compound is communicable to additive that is entrained within the product. The solidified product may be used to form plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.

Abstract: The present invention includes processes and resulting structures for producing moisture absorbing desiccant entrained polymers. A polymer is caused to assume a molten state, typically by applying heat and melting the polymer. To achieve certain results in the hardened end product, such as rigidity and durability, the polymer normally acts as a moisture barrier in a solidified state, both before and after melting. A desiccating agent is blended into the polymer so that the desiccating agent is distributed within the polymer. A channeling agent is also blended into the polymer so that it is distributed within the polymer. Together, the polymer, desiccating agent and channeling agent create a blended mixture. The mixture is solidified so that the channeling agent forms passages in the mixture through which moisture is communicable to desiccating agent that is entrained within the mixture.
