BLOCK OUT LABEL, LABEL SHEET, AND RELATED METHOD

The present invention includes a label, a label sheet and a method for manufacturing the label. The label includes a paper facestock having first and second surfaces and a layer of pressure sensitive adhesive proximal to the second surface. The label can be adhered to a substrate having pre-applied indicia to cover the indicia and the label is opaque enough to prevent the viewing of the covered indicia while matching the color of the substrate.

FOIL PRINTING

Herein is described a method of applying foil from a foil web to a substrate. The method may comprise: ink-jet printing a UV-curable adhesive onto the substrate in a predetermined image area; subjecting the adhesive to a first curing by exposing the adhesive to UV light in a dosage range of 140-170 mJ/cm.sup.2; passing the substrate and a foil web through a nip where the foil web is pressed against the adhesive; subjecting the adhesive disposed between the substrate and the foil web to a second curing by exposing the adhesive to UV light in a dosage of at least 250 mJ/cm.sup.2; and separating excess foil from the substrate, to leave foil on the predetermined image area. Substrates and UV-curable adhesives are also described.

UNITIZED CONSTRUCTON PANEL
20180298609 · 2018-10-18 ·

A process for fabricating a unitized structure comprises creating a multilayer structure by applying a flame-retardant resin to a first layer and stacking, on the first layer, an intermediate layer comprising a honeycomb structure. Further, a second layer is stacked on the intermediate layer and the flame-retardant resin is applied to the second layer. The multilayer structure is then heated to a desired temperature and a pressure is applied about the multilayer structure for a predetermined process time. Moreover, the flame-retardant resin is prevented from entering spaces of the honeycomb structure. After elapse of the predetermined process time, the pressure is released, creating the unitized structure.
