Method of Removing Sulfur Odors From Packages

A package comprising:

• a) a tray, and
• b) a lidstock adhered to the tray,
• wherein at least one of the tray and lidstock comprises a sulfur scavenger;
• wherein the lidstock comprises a coextruded multilayer film comprising a layer comprising an oxygen barrier having an oxygen permeability of less than 500 cm3/O2/m2·day·atmosphere, tested at 1 mil thick and at 25° C. according to ASTM D3985;
• and
• wherein the sulfur scavenger comprises a material selected from the group consisting of
• i) copper metal, copper foil, or copper powder, where the copper is in the zero valence state;
• ii) silica, hydrotalcite, zeolite or alumina treated with copper in the ionic or zero valence state;
• iii) zinc acetate, zinc oxide, zinc stearate, or zinc ionomer;
• iv) iron oxide;
• v) copper (II) oxide;
• vi) magnesium oxide;
• vii) calcium oxide;
• viii) alumina;
• and
• ix) ceria.

A coextruded multilayer film comprising

• a) a layer comprising an oxygen barrier;
• and
• a layer comprising a sulfur scavenger;
• wherein the oxygen barrier comprises a material having an oxygen permeability of less than 500 cm3/O2/m2·day·atmosphere, tested at 1 mil thick and at 25° C. according to ASTM D3985;
• and
• wherein the sulfur scavenger comprises a blend of
• i) magnesium oxide,
• ii) zinc oxide, and
• iii) zeolite.

A heat shrinkable bag comprising a coextruded multilayer film comprising:

• a) a layer comprising an oxygen barrier;
• and
• b) a layer comprising a sulfur scavenger;
• wherein the bag has a free shrink of at least 8% in either or both of the longitudinal and transverse directions;
• wherein the oxygen barrier comprises a material having an oxygen permeability of less than 500 cm3/O2/m2·day·atmosphere, tested at 1 mil thick and at 25° C. according to ASTM D3985;
• and
• wherein the sulfur scavenger comprises a material selected from the group consisting of
• i) copper metal, copper foil, or copper powder, where the copper is in the zero valence state;
• ii) silica, hydrotalcite, zeolite or alumina treated with copper in the ionic or zero valence state;
• iii) zinc acetate, zinc oxide, zinc stearate, or zinc ionomer;
• iv) iron oxide;
• v) copper (II) oxide;
• vi) magnesium oxide;
• vii) calcium oxide;
• viii) alumina;
• and
• ix) ceria.
