Abstract: A method for purifying a contaminated reclaimed HDPE is provided. The method comprises obtaining the contaminated reclaimed HDPE, extracting it with a solvent to produce an extracted contaminated reclaimed HDPE, and then dissolving it in the solvent to produce a first suspension comprising dissolved HDPE and suspended contaminants. The first suspension is settled to produce a second suspension comprising dissolved HDPE and suspended remaining contaminants, and the second suspension is purified by contacting it with solid media to produce a third suspension comprising purer HDPE. Finally, the purer HDPE is separated from the third suspension and it has natural-like optical properties.

Abstract: The present invention generally relates to a method of reducing contamination from plastics. The resulting purer plastic can be used in demanding applications.

Abstract: Sachets composed of metal barrier layers that can include both a sealant and an external protective coating material. The sealant provides heat sealing, and product formulation protection properties, while the barrier material functions to reduce the moisture vapor transmission rate (MVTR) into or out of the sachet.

Abstract: A method for separating and purifying polymers of a reclaimed product (rP) is disclosed. The rP is contacted at an elevated temperature and pressure, with an extraction solvent to produce an extracted rP (erP). A solvent, at conditions sufficient to solubilize the first polymer, contacts the erP to produce a solution, which is purified at an elevated temperature and pressure by filtering it and contacting it with a solid medium to produce a purified solution of the first polymer. The purified polymer is then separated from the purified solution, and the method steps are repeated until all polymers are separated and purified.
