Abstract
A double-sided tape includes a carrier layer having first and second sides opposed to each other, a first adhesive layer located on the first side of the carrier layer, a second adhesive layer located on the second side of the carrier layer, and first defects located between the first side of the carrier layer and the first adhesive layer, or fully within the carrier, or fully within the first adhesive layer. The carrier layer is flexible.
Claims20
A double-sided tape comprising:
- a carrier layer having first and second sides opposed to each other;
- a first adhesive layer located on the first side of the carrier layer;
- a second adhesive layer located on the second side of the carrier layer;
- and
- first defects located between the first side of the carrier layer and the first adhesive layer, or fully within the carrier, or fully within the first adhesive layer,
- wherein the carrier layer flexible.
A method for making a double-sided tape, the method comprising:
- providing a carrier layer having first and second sides opposed to each other over a first roller;
- providing a first adhesive layer over a second roller;
- providing a second adhesive layer over a third roller;
- providing first defects between the first side of the carrier layer and the first adhesive layer
- providing second defects between the second side of the carrier layer and the second adhesive layer;
- and
- rolling the carrier, the first and second adhesive layers, and the first and second defects into the double-sided tape.
A double-sided tape comprising:
- a first carrier layer;
- a second carrier layer;
- a first outer adhesive layer located on one side of the first carrier layer opposite to the second carrier layer;
- a second outer adhesive layer located on one side of the second carrier layer opposite to the first carrier layer;
- an inner adhesive layer located between the first and second carrier layers;
- and
- plural defects located at an interface within the inner adhesive layer,
- wherein the interface is defined by two adhesive layers that form the inner adhesive layer.
