A method of applying a linerless label to an article wherein a web of joined labels is die cut from a web of label material in which the adhesive is protected by a water-soluble coating which provides a cushion between an anvil and die cutting means. The water-soluble coating is at least partially removed by exposure to water in a press following die-cutting, in a label applicator, or in an off-line unit. The web of joined labels may be wound and unwound between each of the above options. The web of joined labels may be separated in a label applicator by breaking a weakened boundary between adjoining labels or by cutting at a boundary between the label and the adjoining label. The linerless label may contain anti-counterfeit means that may be subsequently identified overtly and/or covertly.

Various embodiments of the teachings herein include a corona shielding tape for further processing to give an insulation system comprising an impregnated winding with potential control via outer corona shielding AGS and/or internal potential controller IPS and/or terminal corona shielding EGS, the insulation system being producible by impregnating the winding with an anhydride-free and resin-based impregnating agent at 45-85 C. and under reduced pressure. The corona shielding tape may include: a carrier tape; an electrically conductive and/or partly conductive filler in a polymer matrix; and a tape accelerator suitable for curing and/or gelation of the impregnating agent. The polymer matrix contains at least one polyvinylalcohol and/or a polyvinylalcohol copolymer. The accelerator is selected from the group consisting of: superacids and superacid salts suitable for acceleration of a cationic homopolymerization of the resin-based anhydride-free impregnating agent.

The present invention relates to an adhesive compositions, facestocks and/or packaging labels containing same, where such compositions, facestocks and/or labels are designed to facilitate the recyclability of a plastic article formed from any suitable polymer or mixture of polymers (e.g., a polyethylene terephthalate (PET), high density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), or others of all plastic types), or even glass bottles. In another embodiment, the present invention relates to a method for removing an adhesive composition, facestock and/or packaging label containing same, from a plastic article that is to be recycled.

Provided herein is a water-activated adhesive comprising an aqueous emulsion of vinyl acetate, polyvinyl alcohol, and glycerin. The adhesive has no significant tack prior to being activated, can be repositionable for at least 1 minute after activation, and can form a strong bond less than two hours after activation. Also provided are labels comprising the water-activated adhesive, methods for producing and using the water-activated adhesive, and systems for labeling articles with the water-activated adhesive.

A laminated product in which a first base material layer, an adhesive layer and a second base material layer are stacked in this order, wherein an edge of the laminated product is covered with a layer formed by a curable composition including at least one perfluoropolyether group-containing compound.

A method of configuring tape for securement to a substrate. The tape has a face ply comprising an upper side and a lower side. The method comprises formulating a liner coating by: (a) creating a mixture comprising a non-toxic remoistenable adhesive and activated coconut carbon filtered water; and (b) adding gypsum to the mixture. The method comprises situating an adhesive on the lower side and covering the hot-melt adhesive on the lower side with the liner coating. The method includes using moisture to dispel the liner coating before the tape is applied to the substrate.

The present disclosure relates to an encapsulation adhesive film for a solar cell, comprising a transparent layer in contact with a cell sheet, and a first adhesive film layer in contact with the transparent layer, wherein raw materials of the first adhesive film layer comprise the following components: a resin and a colored filler with a mass ratio of 3 to 25:1, a cross-linking agent accounting for 0.1% to 5% of the total mass of the resin and the colored filler, an auxiliary cross-linking agent accounting for 0.1% to 1% of the total mass of the resin and the colored filler, a coupling agent accounting for 0.1% to 1% of the total mass of the resin and the colored filler, a light stabilizer accounting for 0.1% to 1% of the total mass of the resin and the colored filler, and a photo initiator accounting for 0.1% to 5% of the total mass of the resin and the colored filler. The present disclosure can effectively prevent a white substance from overflowing.

An aqueous NFC containing tail-seal adhesive includes: (a) water; (b) nanofibrillated cellulose; and (c) one or more of: (i) a water-soluble cellulose derivative; or (ii) a water soluble polyol; or (iii) a viscosity modifier other than a water soluble cellulose derivative.

A waterproof membrane is described that includes a barrier layer and a functional layer. The functional layer can include a thermoplastic polymer that changes consistency under the influence of highly alkaline media, and an adhesive. The production and use of the membrane are also described. The functional layer of the membrane can be designed in the form of a film, a coating, or a nonwoven fabric. The fibers in the fabric can include a hard core that is surrounded by a polymer layer, is inert prior to coming into contact with liquid concrete and acts as a protective layer. Thus, the membrane is protected from premature aging and allows work to be performed with the seal in place. During the concreting process, i.e. when the functional layer comes into contact with liquid concrete, the polymer dissolves and thus allows the adhesive to bond to the concrete. The functional layer thus acts as an adhesive sealing compound and the seal is leakproof.

A biodegradable laminate, wherein a polyvinyl alcohol resin layer is laminated on at least one surface of an aliphatic polyester resin layer through an adhesive layer, which is excellent in biodegradability and gas barrier properties, and also excellent in interlayer adhesiveness, is obtained. The adhesive layer comprises, as a main component, a polyester resin (A) which has a polar group and is obtained by graft polymerization of an ,-unsaturated carboxylic acid or an anhydride thereof on a biodegradable polyester resin (A) comprising at least one structural unit selected from structural units represented by the following general formulae (1), (2), and (3): ##STR00001##
