Method to decrease aldehyde content in polyolefin products

A container or closure made in accordance with a method comprising:

• combining with a polyolefin an organic additive compound which comprises an aromatic ring having at least two hydrogen-substituted heteroatoms bonded thereto, wherein the organic additive compound is reactive with aldehyde in the polyolefin to form water and a resulting organic compound comprising an unbridged 5- or 6-member ring including the at least two heteroatoms;
• and
• forming a container or closure comprising the polyolefin.

A composition for use in making a polyolefin item with decreased aldehyde content comprising:

• a polyolefin, and
• an organic additive compound which comprises an aromatic ring having at least two hydrogen-substituted heteroatoms bonded to carbons of the organic additive compound such that the organic additive compound is reactive with aldehyde in the polyolefin to form water and a resulting organic compound comprising an unbridged 5- or 6-member ring including the at least two heteroatoms.

A method for decreasing aldehyde content of a polyolefin comprising:

• incorporating anthranilamide into a polyolefin in an amount effective to react with aldehyde in the polyolefin.

A container or closure made in accordance with a method comprising:

• incorporating anthranilamide into a polyolefin in an amount effective to react with aldehyde in the polyolefin;
• and
• forming a container or closure comprising the polyolefin which has the anthranilamide incorporated therein.

A composition for use in making a polyolefin item with decreased aldehyde content comprising:

• a polyolefin;
• and
• anthranilamide in an amount effective to react with aldehyde in the polyolefin.
