There are provided rolls comprising an air and water barrier article having opposing first and second major surfaces, a pressure sensitive adhesive disposed on at least the first major surface of the article, and a liner having a first major surface that contacts the opposing second major surface of the article, wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll. There are also provided self adhering air and water barrier articles and building envelopes made using the presently disclosed rolls.

Provided herein is a tape roll configured to include an adhesive associated with a color-changing dye to provide the user with a visible marker for the end of the tape roll. In certain aspects, the adhesive is associated with a redox indicator. In certain aspects, the redox indicator is activated upon exposure to air.

The present invention is directed to a two-ply absorbent liner for use in a sterilization process and, more particularly, to an absorbent liner having a foam layer and a paper layer for cushioning sterilization trays and surgical instruments in a sterilization pack and providing advantageous moisture absorption functionality during and after completion of a sterilization process. The absorbent liner functions advantageously with steam or ethylene oxide gas as the sterilization agent. The absorbent liner is fabricated from a foam material, preferably a hydrophilic polymeric foam material, e.g., a hydrophilic polyurethane foam flame laminated to paper, preferably medical grade paper. The disclosed liner may be advantageously utilized in sterilizing surgical instruments and in conjunction with sterilizing trays such that potential residual moisture is eliminated from the surface of the instruments or trays and metal surfaces are cushioned.

Embodiments of the present techniques provide an adhesive tape roll that comprises a plurality of detachable segments. The detachable segments comprise a pull tab to help separate a protective liner layer, or backing layer/backing liner, from the adhesive tape at the point of use. Thus, a user may detach a segment from the roll, and then use the pull tab to separate the adhesive tape from the backing liner.

An underlayment for supplementing one or more physical properties of wall, ceiling, and floor construction components is used to in a wall, ceiling, or floor assembly that may be fabricated on site. The assembly includes: first and second wall, ceiling, or floor construction components which each have physical properties and an underlayment component which has at least one supplemental physical property for supplementing the physical properties of the first and second construction components. The construction components may or may not be secured together with the underlayment sandwiched between the second and first construction components to form a wall, ceiling, or floor assembly with the supplemental physical property or properties of the underlayment. The supplemental physical property or properties of the underlayment may include, but are not limited to, latent storage of thermal energy, sound transmission reduction, and/or burn through resistance.

There are provided rolls comprising an air and water barrier article having opposing first and second major surfaces, a pressure sensitive adhesive disposed on at least the first major surface of the article, and a liner having a first major surface that contacts the opposing second major surface of the article, wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll. There are also provided self adhering air and water barrier articles and building envelopes made using the presently disclosed rolls.

Provided is an adhesive article which requires no separator and exhibits sufficient adhesive force without the need of any operation for adhesive-force development and in which the adhesive layer, even when in contact with itself, can be peeled off at the interface. The adhesive article includes an adhesive body including an adhesive layer, wherein the adhesive layer has a gel content of 5-70%, the adhesive article, through 7-day storage at 40 C., has a change in the gel content of the adhesive layer of 5% to 5%, and surface portions of the adhesive layer are in contact with each other.

The present invention relates to a self-adhesive waterproof coiled material of a super-strong cross laminated film, comprising sequentially from top to bottom: an isolation protection layer, a non-asphalt-based self-adhesive layer, a strong cross laminated film, an asphalt self-adhesive layer and a PE isolation film. One side of the upper surface of the coiled material is provided with an overlap edge, and the other side of the lower surface of the coiled material is also provided with an overlap edge. The waterproof coiled material provided in the present invention has better adhesive property with post-cast concrete than an asphalt-based coiled material, and can be better bonded to a main body structure (i.e., pre-paving anti-sticking coiled material); the strong cross laminated film in the middle of the coiled material has good ductility, so that when the base layer slightly subsides or the main body structure is slightly deformed, the coiled material can continue to be well bonded to the main body structure and would not be separated; and a good waterproof effect thus can be achieved.

The invention relates to the packaging of one or more articles in a packaging sheet material which is moveable from a first condition to a second, expanded, condition to improve the packaging effect of the sheet material. In accordance with the invention the sheet material includes a first portion with apertures which can be moved to an open position to create the second, expanded, condition and at least one, but typically a plurality of spaced apart, second portions which have no apertures, or a different shape and/or pattern of apertures than the apertures of the first portion, so as to form a surface of the said second portion more suitable for the application of a label and/or indications thereon when the sheet material is in the second expanded condition.
