There is provided a barrier film including a barrier layer having two opposing major surfaces, wherein the barrier layer comprise buckling deformations and non-buckling regions; a first organic layer in direct contact with one of the opposing major surfaces of the barrier layer; a second organic layer in direct contact with the other of the opposing major surfaces of the barrier layer; and a substrate in direct contact with the first organic layer or the second organic layer.

Extensible barrier films, articles employing same and methods of making same

The present application is directed to a method of using a hardenable dental article. The method can include providing the hardenable dental article; applying the hardenable dental article to a dental structure; customizing the shape of the hardenable dental article; and at least partially curing the hardenable dental article.

Methods of using hardenable dental articles

There is provided a barrier film including a barrier layer having two opposing major surfaces, a first organic layer in direct contact with one of the opposing major surfaces of the barrier layer; a second organic layer in direct contact with the other of the opposing major surfaces of the barrier layer; and a substrate in direct contact with the first organic layer or the second organic layer; wherein the barrier layer comprises buckling deformations with average spacing smaller than average spacing of the buckling deformations in the first or second organic layer.

A method of making extensible web laminates comprising a multilayer film and at least one web layer and the use of such extensible web laminates in personal care articles. The method generally includes activating the multilayer film in a first direction by stretching at least a portion of the multilayer film past the elastic deformation limit of the skin layers and recovering the skin layers with the elastomeric core layer to produce a multilayer film that is elastic in the first direction. The activated multilayer film is subsequently stretched beyond the deformation limit of the skin layers in a second direction substantially perpendicular to the first direction. At least one web layer is applied to the multilayer film while in the stretched state. The multilayer film is then recovered to produce an extensible web laminate.

Method of making extensible web laminates

A hardenable dental article including a base and at least one outer surface extending from the base, wherein at least the base and the at least one outer surface of the hardenable dental article includes a hardenable dental material; and a multi-layer polymeric film conformable release liner in contact with at least a portion of the at least one outer surface.

Preformed malleable dental articles and methods

The present invention relates to retroreflective elements and retroreflective articles such as pavement markings comprising retroreflective elements, methods of making retroreflective elements, and laminates.

Retroreflective elements and articles

The present invention discloses methods of controlling the puncturability, and optionally the sealability (the ability of a film to conform around a puncturing object) and resealability (the ability of a film to close a hole made by a puncturing object), of polymeric films. Systems comprising a film and puncturing object are also disclosed. Puncturability is controlled by achieving targeted levels of the friction between the film and a puncturing object, the film's flexural rigidity, the film's recovering stress, and the film's elongation at break.

Controlled-puncture films

Microtextured elastomeric materials having at least one elastomeric core layer or region and at least one skin layer wherein the skin layer has a semi-crystalline or amorphous polymer and an elastomeric block copolymer or pressure sensitive adhesive, the combination of which is less elastic than the core layer and will undergo permanent deformation at the stretch percentage that the elastomeric laminate will undergo. The materials are suited for use in applications such as respirators.

Elatomeric laminates and composites

An adhesive tape is provided which comprises a woven cloth, a polymer embedded into the cloth so as to cause the warp and weft fibers of the cloth to bond together at their overlapping points but not to completely encase the fibers, and a pressure sensitive adhesive coated onto at least a portion of the polymer, wherein the adhesive tape is hand tearable in the down-web and in the cross-web direction. A method of manufacturing such a tape is also provided.
