The invention relates to an activatable adhesive label comprising a flexible web-shaped viewing material. At least one adhesive layer made of a moisture-activatable adhesive that is not adhesive in the dry state is applied onto one side of the flexible viewing material, wherein at least one central layer is provided which is designed to be adhesive and which is arranged between the viewing material and the adhesive layer.

An adhesive formulation such as a hot melt adhesive or a pressure sensitive adhesive is provided comprising 5 to 98% (by weight) biodegradable substantially non-crystalline mcl-PHA. The mcl-PHA may be cured with a peroxide curing agent. The adhesive formulation may include an additional biodegradable polymer, or a non-biodegradable thermoplastic elastomer. Hot melt adhesives comprising significant amounts of biodegradable mcl-PHA, waxes, and tackifiers are also provided.

The present invention provides a metal-plastic composite material having excellent adhesive strength and formability and a method for manufacturing the same, and specifically, the present invention provides a metal-plastic composite material and a method for manufacturing the same comprising: a metal layer; and a plastic layer on at least one surface of the metal layer, wherein a thin film layer formed of a silane coupling agent is provided between the metal layer and the plastic layer, and the metal layer and the plastic layer are bonded by covalent bonding with the silane coupling agent.

Provided is a method of manufacturing a laminated film, the method including laminating a glass film and a resin film via an adhesive layer, by which peeling between the glass film and the resin film is prevented, and hence a laminated film excellent in appearance can be obtained. The method of manufacturing a laminated film of the present invention includes the steps of: laminating a glass film and a resin film via an adhesive to provide a precursor laminate; and curing the adhesive by applying an active energy ray to the precursor laminate, wherein the curing step includes nonuniformly applying the active energy ray in a surface of the precursor laminate.

Disclosed herein is a method of making polymerizable bio-based monomers containing one phenolic hydroxyl group which has been derivatized to provide at least one polymerizable functional group which is an ethylenically unsaturated functional group (such as a [meth]acrylate group), where the precursors of the polymerizable bio-based monomers are derived from raw lignin-containing biomass. Also disclosed herein are bio-based copolymers prepared from such bio-based monomers and a co-monomer, and methods of making and using such bio-based copolymers. In particular, the bio-based copolymers can be used as pressure sensitive adhesives, binders, and polymer electrolytes.

The invention relates to the use of a low Tg compatible resin as an adhesive layer for the welding of a thermoplastic composite structure to a thermoplastic or thermoset structure. The invention is especially good for the welding of large parts, such as wind turbine halves and spar caps. A useful thermoplastic composite is one formed by the infusion and curing of long fibers by a reactive acrylic liquid resin system, such as ELIUM® resin systems from Arkema.

Stretch-release adhesive articles with tunable mechanical properties are provided. The articles include a stretchable carrier extending along a first direction and including a first major surface and a second major surface opposite the first major surface. At least one of the first and second major surfaces of the stretchable carrier is a stretch-releasable adhesive surface, and the stretchable carrier includes a pattern of slits distributed thereon and configured to deform upon a stretch on the stretchable carrier to elongate the stretchable carrier.

A label and liner assembly comprises one or more labels, the label(s) including a facestock and an adhesive layer on a surface of the facestock. A support liner is releasably adhered to the adhesive layer, the support liner defining a plurality of embossings projecting from a surface of the support liner toward or away from the label. A transfer tape and a method for assembling label material are also provided.

A method of applying an adhesive film to a component includes applying an adhesive film to a surface of a component, wherein the adhesive film is positioned between the surface and an elastic membrane, the elastic membrane is transferred into a curved state with a convex and a concave side and contacted with the surface with the convex side first such that an adhesive layer of the adhesive film is pressed onto the surface in a full-area by the elastic membrane, the adhesive layer is pressed onto the surface in a full-area by a negative pressure being applied to that side of the elastic membrane facing towards the adhesive film, and to stabilize the component against deformation brought about by this negative pressure, the elastic membrane along with the adhesive film is pushed against the surface of the component with a plunger means.

A pressure-sensitive adhesive sheet includes a resin film as a substrate and a pressure-sensitive adhesive layer provided on a first face of the substrate. In the pressure-sensitive adhesive sheet, a second face of the substrate is a release face, and the second face has a slip resistance value of 3.5 N or more. The pressure-sensitive adhesive sheet has a high-speed peel strength of 4.5 N/20 mm or higher, which is measured under conditions of a tensile speed of 30 m/min after 30 minutes of application to a stainless steel plate, and it has a difference between the maximum and minimum values of a self-backside adhesive strength of 1.5 N/20 mm or lower, which is measured under a condition of a tensile speed of 30 m/min.
