  • Method to decrease aldehyde content in polyolefin products
    Patent number: 6632874
    Abstract: Methods are provided for decreasing aldehyde content in polyolefin materials comprising combining with the polyolefin material an organic additive compound which reacts with aldehydes to form water and a resulting organic compound. The organic additive compound comprises at least two hydrogen-substituted heteroatoms bonded to carbons of the organic additive compound such that the organic additive compound is reactive with aldehydes present in the polyolefin to form water and the resulting organic compound, which comprises an unbridged five- or six-member ring including the at least two heteroatoms. The resulting organic compound advantageously neither imparts an off-taste to food and beverage products in contact with the polyolefin nor discolors the polyolefin. Preferred polyolefins include polypropylene and polyethylene.
