Provided herein is a pressure sensitive adhesive (PSA) comprising a polycrylate base polymer, a crosslinker and a fluorescer. The crosslinker does not comprise a metal acetylacetonate, a metal alkoxide, or an alkoxy-metal acetylacetonate, and the fluorescer comprises less than 0.1 wt. % metal oxide based on the solid weight of the adhesive. The adhesive is resistant to yellowing under adverse conditions such as high temperature treatment and/or exposure to UV.

An acrylic emulsion pressure sensitive adhesive composition is provided. The acrylic emulsion pressure sensitive adhesive composition, due to pH-dependent properties, exhibits stable adhesion when attached to an adherend, but when it needs to be removed, it can be easily removed without residue using an alkaline solution. Thus, if the acrylic emulsion pressure sensitive adhesive composition is used as a pressure sensitive adhesive for a label of a plastic packaging article, the label can be easily removed during a recycling process, thus improving recycling efficiency.

A label assembly includes a label print layer with enhanced tensile, tear, and/or stiffness properties. The enhanced property or properties may be achieved by including a reinforcement layer, including a reinforcement material in the adhesive layer, and/or modifying the facestock layer.

A release substrate includes: a carrier substrate having a front side and a reverse side opposite the front side, and a release layer disposed on the front side and/or reverse side of the carrier substrate. The release layer includes a polymeric binder and a wax based on a vegetable oil.

A printable 2-PLY security tape includes a first tape PLY label stock. A first substrate has a printable outer surface as a first outer PLY surface. A first inner PLY surface includes at least one first release area disposed on an inside surface of the first substrate, and at least one first adhesive area is disposed on the inside surface of the first substrate. A second tape PLY security tape includes a second substrate outer surface as a second outer PLY surface. A second inner PLY surface includes at least one second release area disposed on an inner surface of the second substrate, and at least one second adhesive area disposed on the inner surface of the second substrate. The second adhesive area is in contact with the first release area and the first adhesive area in a contact with the second release area, to form a 2-PLY composite tape.

A method is disclosed for producing a polyurethane film including the steps of depositing a prepolymer composition, drying the prepolymer composition, and crosslinking the propolymer composition.

The present disclosure relates to transparent flame-retardant coating compositions and labels including layers comprising the same. The coating composition comprises a high-hydroxyl value polymer, a crosslinker, and a flame-retardant additive comprising a phosphinate compound. The coating composition may be coated on a substrate such as a label. The coating composition forms a layer that advantageously has flame-retardant properties and is optically clear.

The an adhesive composition characterized in that the kisstack, which is defined as the force measured when a sheet coated with the adhesive composition is instantaneously peeled off after being attached, is about 6 N/inch or higher. The composition not only has excellent loop tack but also exhibits high kisstack characteristics, and thus can be widely used for various substrates.

Disclosed are hot-melt, curl-free methods, structures, and compositions, which in flexible packaging applications, reduce mineral-oil, hydrocarbon migration into packaged food. One embodiment provides an optionally oriented base film having a first side and a second side that is a transparent or opaque film. Further, the composition comprises, consists essentially of, or consists of a water-based primer applied to the first side. Further still, the composition includes a barrier layer to mineral-oil migration, wherein the barrier layer is located between the adhesive-receptive layer and the polymeric substrate, and wherein the barrier layer consists essentially of: (i) polymers of polyvinyl alcohol, ethylene vinyl alcohol, polyester, polyamide, or combinations thereof; and (ii) optionally additives. The barrier layer provides a barrier to mineral-oil migration of 0.1 μg/day*dm.sup.2 or less at 40° C. for 40 days, and the curl-resistant composition does not curl when heated for at least one hour at 60° C.

An object is to provide a water-dispersible paper that exhibits excellent dispersibility in water. As a solution, a water-dispersible paper is provided, which has: a base paper that has a bulky layer containing 10% by weight or higher of a softwood pulp with a lumen width (l) to fiber diameter (D) ratio (l/D) of 0.60 or lower on average; and a water-soluble polymer impregnated into the base paper.
