Abstract
A label with improved physical properties comprising: a base layer having a microstructured area; a composite microstructure having a first, second and third set of microstructures disposed on the microstructured area; a dry lift force attributable to the composite microstructure greater than 7 pounds according to lift testing; a wet lift force attributable to the composite microstructure greater than 7 pounds according to lift testing; an adhesive layer affixed to the base layer for affixing the label to a container; and, thereby providing a microstructured label having improved gripping physical properties that can be affixed to a container.
Claims22
A contact surface for an object comprising:
- a base layer having a microstructured area;
- a composite microstructure disposed on the microstructured area comprising:
- a first set of microstructures having a first micro-feature with a first width between 80 μm and 120 μm;
- and
- a second set of microstructures having a second micro-feature with a second width less than the first width.
A contact surface for an object comprising:
- a base layer having a microstructured area;
- a composite microstructure disposed on the microstructured area comprising:
- a first set of microstructures disposed on the base layer;
- a second set of microstructures having a first portion disposed on the base layer and a second portion disposed on the first set of microstructures;
- and
- a third set of microstructures having a first portion disposed on the base layer, a second portion disposed on the first set of microstructures, and a third portion disposed on the second set of microstructures;
- and
- an adhesive layer affixed to the base layer configured to affix the base layer to the object.
A contact surface for an object comprising:
- a set of microstructures, disposed on a surface, comprising:
- a first micro-feature having a width in the range of 15 μm to 3000 μm, a depth in the range of 30 μm and 1500 μm and pitch in the range of 100 μm and 3000 μm;
- and
- a second micro-feature having a width between 25% and 41% smaller than the first micro-feature width;
- wherein a contact percentage attributable to the set of microstructures between the set of microstructures and skin of a person gripping the surface is in the range of 1% to 25%.
A contact surface for an object comprising:
- a base layer having a microstructured area;
- a composite microstructure disposed on the microstructured area comprising a first set of microstructures having a first micro-feature, wherein the composite microstructure has a depth of between 30 μm and 250 μm and wherein a contact percentage attributable to the composite microstructure between the first set of microstructures and skin of a person gripping the surface is in the range of 1% to 25%;
- and
- an adhesive layer affixed to the base layer configured to affix the base layer to the object,
- wherein the composite microstructure increases a grip force compared to a contact surface without a composite microstructure thereon.
