Abstract
Disclosed herein are feminine hygiene articles and multilayer film structures. According to one or more embodiments disclosed herein, a feminine hygiene article may include a feminine hygiene pad including an absorbent body, an adhesive layer positioned on at least a surface of the absorbent body, and a pouch wrap in contact with the adhesive layer of the feminine hygiene pad. The pouch wrap may include a release layer in direct contact with the adhesive layer. The release layer may include a polymer composition including low density polyethylene covalently bonded to polydimethylsiloxane.
Claims13
A feminine hygiene article comprising:
- a feminine hygiene pad comprising an absorbent body and an adhesive layer positioned on at least a surface of the absorbent body;
- and
- a pouch wrap in contact with the adhesive layer of the feminine hygiene pad, the pouch wrap comprising a release layer in direct contact with the adhesive layer, the release layer comprising a polymer composition comprising low density polyethylene covalently bonded to polydimethylsiloxane;
- wherein the polymer composition comprises the reaction product of the copolymerization of ethylene and (meth)acrylic ester functionalized polydimethylsiloxane;
- and
- wherein the reaction product of the copolymerization of ethylene and (meth)acrylic ester functionalized polydimethylsiloxane comprises one or more of the following structures:
- where R is a methyl group or a hydrogen, R1 is a bridge group that connects functional group ((meth)acrylate) with siloxane, R2 is an end group selected from the group consisting of alkyl, substituted alkyl, aryl, alkenyl, H, and OH, x is an integer from 10 to 1000, and y is an integer from 1 to 20.
A multilayer film structure comprising:
- one or more support layers comprising polymers;
- and
- a release layer in direct contact with a support layer, the release layer comprising a polymer composition comprising ethylene and (meth)acrylic ester functionalized polydimethylsiloxane copolymers;
- wherein the polymer composition comprises the reaction product of the copolymerization of ethylene and (meth)acrylic ester functionalized polydimethylsiloxane, wherein the ethylene and (meth)acrylic ester functionalized polydimethylsiloxane comprises one or more of the following structures:
- where R is a methyl group or a hydrogen, R1 is a bridge group that connects functional group ((meth)acrylate) with siloxane, R2 is an end group selected from the group consisting of alkyl, substituted alkyl, aryl, alkenyl, H, and OH, x is an integer from 10 to 1000, and y is an integer from 1 to 20.
