The inventive perforated tape is a masking tape that has an elongate tape member further having a polymer coating top layer, a biodegradable paper mask layer middle layer, and a biodegradable polymer perforated lining member contiguously coupled to a bottom surface of the paper mask layer, a plurality of hole members parallelly disposed laterally and longitudinally substantially covering the entire polymer perforated lining member. The polymer perforated lining member further includes a plurality of solid portions of the polymer perforated lining member disposed laterally and longitudinally between the plurality of hole members adapted to resist tear so the elongate tape member tears substantially perpendicularly to longitudinal sides of the elongate tape member along a user-selected one row of a plurality of linear rows of hole members. An adhesive compound is disposed substantially on the entire bottom surface of the perforated lining member.

Embodiments of a method for removing a tattoo through patterned trans-epidermal pigment release includes determining first treatment area of skin of a patient through a primary template including primary apertures, marking the first treatment area of skin of the patient along borders of the primary apertures to outline a grid of primary tegulae, and delivering a tattoo removal fluid to the marked first exposed skin. In an alternate embodiment, a template, which may be adhered to the skin, is used during a microneedling process to create a structured, patterned procedure to remove skin irregularities. The template has a plurality of needle apertures, an adhesive layer, and a release liner. The release liner may be removed, exposing the adhesive layer, so that the template, with the plurality of needle apertures, may be positioned over the skin irregularity.

Certain embodiments described herein pertain to optical sensors, systems and methods for continuous glucose monitoring. In some embodiments, methods of preparing a layered optical sensor are disclosed. The optical sensor can be formed by laminating a plurality of sheets together to form a final sensor. In some embodiments, the sensor tip comprises a oxygen conduit, an enzymatic layer, and an sensing layer. In some embodiments, the sensor includes a plurality of waveguides configured to direct light to and from a target material, such as an oxygen sensing polymer. Systems are also disclosed for an adhesive system for attaching an optical sensor-transmitter system. Methods and systems are also disclosed for a sensor inserter system. The inserter can include a lancet tip that includes a convex feature attached to a first surface of the lancet tip.

The present disclosure provides filters that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

A heat-treated non-oriented principal film including a cast (co)polymeric component that is not capable of thermally-induced self-forming. The heat-treated principal film has first and second opposed major faces and at least one modification zone on the first major face, each modification zone including a central portion and a rim portion surrounding the central portion. Each rim portion is surrounded by a land portion. An average thickness of each rim portion is greater than an average thickness of the land portion surrounding each modification zone, and an average thickness of each central portion is less than the average thickness of the land portion, or zero. The first major face of the heat-treated principal film may be positioned in contact with an oriented carrier film including a molecularly-oriented (co)polymer that exhibits a relaxation temperature (T.sub.r). Methods of making such films and hand-tearable adhesive articles including such films are also disclosed.

There is herein described a range of sporting products comprising sucker elements, which can be used in various uses such as on products which require, for example, hand or any other type of grip contact. The grip contact may be with the feet or hands (or any other part of the body). The sporting products that the grips may be used on may comprise rackets (e.g. for tennis/badminton/squash etc.), bats (e.g. cricket/baseball/table-tennis etc.), bicycles, motorcycles, golf clubs, water sports (surfing, windsurfing) etc. The sucker elements may also be included with other sporting product such as on the inside and/or outside of running sock or shoes for example. There is also described a range of industrial products comprising sucker elements which can be used in a range of applications such as on a range of vehicle parts (e.g. bus rails, train rails, boat rails, steering wheels, motorbike handles and foot pegs etc.), industrial machinery (e.g. handles for tools such as drills, pneumatic drills etc.), flooring (e.g. decking on boats and in industrial environments), crockery, bathroom and shower flooring, and surfaces to aid disabled people.

A polymeric tape comprises a facestock extending lengthwise, the facestock including a polymer. An adhesive layer is on a first surface of the facestock. Tear-cuts are formed into at least one longitudinal edge of the facestock and extending inwardly, the tear-cuts being provided all along the at least one longitudinal edge of the facestock.

Provided is an adhesive tape in which each of at least one perforation line includes: a plurality of separation parts at which one side portion and an other side portion of the adhesive tape are separated away from each other in its longitudinal direction; a connection part through which the one side portion and the other side portion are connected to each other in the longitudinal direction, the connection part located between two adjacent separation parts in a width direction of the adhesive tape; and a weak connection part through which the one side portion and the other side portion are connected to each other in the longitudinal direction, the weak connection part having a smaller breaking strength than the connection part, and the perforation line includes at least one group including the connection part and the weak connection part adjacent to each other in the width direction.

The disclosed thermally bondable adhesive tape backing has a pressure-sensitive adhesive at a surface and a thermoplastic polyurethane adhesive at an opposite surface for thermal bonding to a device. The thermoplastic polyurethane adhesive softens and melts at a relatively low temperature. Therefore, melting of thermoplastic polyurethane adhesive is achieved while the pressure-sensitive adhesive remains in place and is not pressed away at the region of the thermal bonding.
