A laminate composite material (1), suitable for the packaging of food products and having a multilayer structure comprising: a first outer layer (21) of paper or plastic film; an inner layer (22) of adhesive; and an intermediate layer (23) interposed between the first and the second layer and made of sodium silicate (Na.sub.2O×SiO.sub.2).

The present invention provides a low tack bubble free advertisement film, comprising an advertisement film layer, a dot glue layer and a release layer; a adhesion promoter layer is disposed between the back face of the advertisement film layer and the dot glue layer; the dot glue layer consists of over four independent, separable glue dots; and the area of the dot glue layer is 30-80% of the adhesion promoter layer. The present invention can provide a special advertisement film in the field of advertising consumables. The advertisement film has many advantages, such as low tack, totally bubble free, removable, and can be pasted for a long time. The present invention provides a convenient, efficient, feasible solution for advertising consumables.

A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.

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.

Adhesive tape with an extended liner tab. A method of making a tape with an extended liner tab, by (A) providing a release liner-backed double-sided adhesive tape; (B) isolating a tape slug from the adhesive tape; (C) removing the tape slug so as to expose an underlying length of the release liner; and (D) cutting through the release liner so as to form the extended liner tab. Apparatus for performing the method, and release liner-backed double-sided adhesive tape comprising a plurality of spaced apart finite lengths of an adhesive tape and a release liner, with an exposed length of release liner disposed between adjacent lengths of adhesive tape.

The invention relates to a process for the manufacture of polymer film graphics comprising providing a continuous substrate having a release layer thereon; applying an image layer in the shape of a graphic letter or design to the release layer; depositing an adhesive layer to the image layer and which has the same shape as the image layer graphic letter or design; curing the adhesive and image layers; and winding the polymer film graphics onto rolls. The invention further relates to a polymer film graphic comprising a substrate having an upper surface and a lower surface; a release layer overlying the upper surface of the substrate; an image layer in the shape of a graphic letter or design overlying the release layer; an adhesive layer overlying the image layer, the adhesive layer having the same shape as the image layer graphic letter or design.

Stiffening assemblies for use with labels or shelf label channels are described. The stiffening assemblies can be incorporated with one or more labels and provided so as to be conveniently used with shelf label channels or other point-of-sale displays.

A multilayer protective tape for rotor blades of wind energy turbines said tape having a protective top layer comprising a polymer film and an adhesive bottom layer, wherein the top layer has a continuous surface (S) that is outwardly curved or outwardly trapezoidal surface such that the tape has a cross-sectional profile having an inner section between two lateral sections and wherein the inner section has a thickness (Ti) made up by the thickness of the top layer and adhesive bottom layer that is greater than the thickness of at least one of the lateral sections (T1,T2) made up by the thickness of the top layer and adhesive bottom layer and wherein the thickness (T1 or T2) of at least one lateral section is at most 600 μm and the thickness of the inner section (Ti) is at least 330 μm. Also provided are processes for making profiled tapes and methods for applying the tapes to rotor blades and blades containing protective tapes.

A water vapour-permeable building sheet material, that may be adhered in overlapping relationship against a building structure, includes a water vapour permeable membrane having first and second opposing surfaces, wherein the surface energy of the second opposing surface is less than 35 mN/m; an adhesive layer that is vapour permeable, applied to the first face of the membrane; and an adhesive region applied to the second opposing surface. Two segments of the sheet material may be placed in overlapping relationship so that adhesive in the adhesive layer applied to the first face of the membrane of one of two segments adheres to the adhesive region applied to the second opposing face of the other of the two segments to form a substantially air impermeable boundary between the two segments, when overlapping, preventing lateral migration of air between the two segments. A building envelope may be so formed.

The present invention relates to a method for the production of a cladding for elongated material (2), in particular a sheath for cable sets. In this method, an adhesive tape (3, 4) consisting of a carrier (4) and a first adhesive coating (3) which substantially fully covers the front side of the carrier (4) is combined with an adhesive-free carrier tape (5) such as to form a laminate (3, 4, 5). This is carried out such that the adhesive tape (3, 4) is applied to the carrier tape (5) with its first adhesive coating (3) in such a way that a first projection (U.sub.1) is defined along at least one of the two longitudinal edges of said adhesive tape. According to the invention, the carrier (4) of the adhesive tape (3, 4) is additionally provided with a further second adhesive coating (7) substantially in parts of its rear side.
