Abstract

Methods and compositions for securing to and removing adhesive tapes from substrates, e.g., delicate substrates such as skin, are described. The methods include providing an adhesive tape comprising an adhesive layer and a support layer in contact with the adhesive layer. A first adhesion level between the adhesive layer and the support layer is, or can be controlled to be, less than a second adhesion level between the adhesive layer and the substrate. The methods further include applying the adhesive tape to the substrate by contacting the adhesive layer to the substrate while the support layer remains in contact with the adhesive layer; and removing the support layer from the substrate by separating the support layer from the adhesive layer.

Claims

1. A quick-release tape comprising:

a support layer, comprising;

a backing layer, and

a patterned release agent layer disposed on a first side of the backing layer;

an adhesive layer disposed on the release agent layer; and

an antiadhesive cover layer in contact with the support layer,

wherein the tape is provided in a roll such that in the roll, the cover layer is in contact with a second side of the backing layer,

wherein an adhesion level between the cover layer and the support layer is less than an adhesion level between the adhesive layer and the support layer, and

wherein the adhesion level between the adhesive layer and the support layer is greater than an adhesion level between the adhesive layer and the cover layer.

2. The tape of claim 1, wherein when the adhesive layer is disposed on a substrate, a first adhesion level between the adhesive layer and the substrate is greater than a second adhesion level between the adhesive layer and the support layer.

3. The tape of claim 1, wherein an adhesion level between the adhesive layer and the release agent layer is a function of an angle of a force applied to an interface between the adhesive layer and the release agent layer.

4. The tape of claim 1, wherein the release agent layer includes first domains and second domains.

5. The tape of claim 4, wherein a first adhesion level between the first domains and the adhesive layer is different from a second adhesion level between the second domains and the adhesive layer.

6. The tape of claim 4, wherein an adhesion level between the adhesive layer and the support layer is a function of a fraction of the area of the release agent layer composed of the first domains.

8. The tape of claim 1, wherein the cover layer is disposed on the adhesive layer.

7. A quick-release tape comprising:

a support layer, comprising;

a backing, and

a release agent layer disposed on a first side of the backing layer;

an adhesive layer disposed on the release agent layer; and

an antiadhesive cover layer in contact with the support layer,

wherein the tape is provided in a roll such that in the roll, the cover layer is in contact with a second side of the backing layer,

wherein an adhesion level between the cover layer and the support layer is less than an adhesion level between the adhesive layer and the support layer,

wherein the adhesion level between the adhesive layer and the support layer is greater than an adhesion level between the adhesive layer and the cover layer, and

wherein the release agent layer is formed of a material having an adhesion level that changes in response to a stimulus.
