Abstract: Fluid activatable adhesive compositions and activating fluid(s) for activating the adhesive composition are described herein. The adhesive compositions contain at least two polymers with different hydrophilicities. The hydrophilic polymer has quick tack when exposed to a hydrophilic solvent, such as water or other aqueous solvent, while the hydrophobic polymer provides strong adhesion to a paper or polymeric substrate. The adhesive composition may contain particulate fillers which enable fast exhaustion of the activation fluid out of the adhesive when applied to a substrate, thereby allowing the hydrophobic polymers of the adhesive composition to achieve strong adhesion of the liner-free label to the paper or polymeric substrate. The particulate fillers may also function as anti-blocking agents when liner-free label media are tightly wound in a roll.

Abstract: A method of producing a substrate suitable for artificial leathers. The substrate is composed of an entangled nonwoven fabric made of microfine fibers and a binder resin. At least one surface of the substrate is a densified layer which is made of the microfine fibers and which is substantially free from the binder resin. The binder resin is impregnated into a portion of the substrate other than the densified layer. The densified layer prevents the binder resin impregnated into the entangled nonwoven fabric from migrating into the surface of the entangled nonwoven fabric, thereby providing the substrate having the surface substantially free from the binder resin. The peeling strength between the substrate and a grain layer formed on the surface thereof is drastically improved because the surface of the substrate is substantially free from the binder resin.

The solvent can be effectively used for labeling of heat-shrinkable polyester-based labels.

Abstract: A packaging and method for controlling the seal strength between two cooperating thermo-sealable films at predetermined sealing portions, where a predetermined amount of heat is applied over a predetermined period of time. The resulting packaging is resealable after the first separation of two surfaces. The strength of the seal controlled by defining the number and dimensions of a plurality of restricted areas without a material cover that is resistant to the thermo-seal effect. The restricted area can be defined with a plurality of dots of predetermined selected shapes and dimensions. The resulting article facilitates the rupture of the packaging along a predetermined path. With this process, a fixed predetermined heat and residency time can be chosen and the seal strength can still be varied in different areas of a packaging. Non-sealable microdots with a predetermined amount of adhesive deposits also covered by a polypropylene powder deposit permit its resealing.

Abstract: A two component, curable hot melt adhesive system includes a first hot melt adhesive formulation which has a softening temperature greater than room temperature and which includes a first component of a curable adhesive therein. The system includes a second hot melt adhesive formulation which has a softening temperature which is greater than room temperature and which includes a second component of a curable adhesive therein. The second component is reactive with the first component to provide a cured adhesive bond.

The mixture cools to provide a thermoplastic bond which subsequently cures to provide a permanent adhesive bond. While the first and the second component individually perform as hot melt adhesives, combining the first and the second gives enhanced adhesive performance in extended temperature ranges.
