Methods of delivering fragrance using ethylene vinyl acetate ribbon

A substrate in a form of a transparent sheet comprising:

• a copolymer of an olefin and at least one olefin derivative;
• and
• a fragrance,
• wherein the substrate is substantially free of homopolymeric material,
• wherein the substrate has a thickness of from about 10 to about 50 mils, and
• wherein the time required for the substrate to achieve about 0.008 g/cm2 cumulative fragrance emission ranges from about 5 to about 40 days.

A substrate in a form of a transparent sheet comprising:

• a copolymer of an olefin and at least one olefin derivative selected from the group consisting of vinyl esters of saturated carboxylic acid, propenyl esters of saturated carboxylic acid, olefinically unsaturated organic acids and esters, and mixtures thereof;
• and
• a fragrance,
• wherein the substrate is substantially free of homopolymeric material;
• wherein the substrate has a thickness of from about 10 to about 50 mils;
• wherein the time required for the substrate to achieve about 50% cumulative fragrance depletion ranges from about 5 to about 40 days;
• and
• wherein the time required for the substrate to achieve about 0.008 g/cm2 cumulative fragrance emission ranges from about 5 to about 40 days.
