Abstract: An inerted plate dryer for drying solvent based coating is disclosed. The dryer uses two tiers of substantially parallel heating plates that are located not more than 10 cm apart. A moving web with solvent based coating is passed through the dryer, and runs closer to one of the heating plates. The method of using such inerted plate dryer is also disclosed.

Abstract: The present invention is directed toward multilayer pressure-sensitive adhesive constructions with improved convertibility and aging. In one embodiment, the multilayer constructions have one layer formed of a first adhesive composition having a first glass transition temperature, and also having a tangent delta greater than about 0.5 at 102 radians per second at 20° C., and a storage modulus greater than about 3×108 dynes/cm2 at 104 radians per second at 20° C. At least a second adhesive layer is provided in the construction, the second adhesive layer comprising a second adhesive composition with a second glass transition temperature.

Abstract: An improved hot-melt pressure-sensitive adhesive (HMPSA) composition contains an elastomeric component, such as a blend of SIS and SB block copolymers, and a tackifying component comprising one or more intermediate softening point resins (ISPRs) having a ring and ball softening point of from 35 to 60° C. The improved adhesive compositions are characterized by reduced volatility, less bleed and staining tendencies, and improved overall adhesive performance. The invention also provides improved label constructions in which a release liner is coated with an HMPSA composition and laminated to a flexible facestock. Notably, even when low basis weight paper facestocks are used, the construction can be converted at high speeds.

Abstract: Disclosed herein is a primerless removable pressure sensitive adhesive construction comprising an unprimed facestock, a first adhesive layer in contact with the facestock, a second removable pressure sensitive adhesive layer in contact with the first adhesive layer, and a release surface in contact with the second adhesive layer. Advantageously, constructions of this design exhibit improved layflatness in comparison to conventional emulsion primed removable pressure sensitive adhesive constructions.

Abstract: There is provided a laminate of a backing, a layer of permanent pressure-sensitive adhesive and a layer of removable pressure-sensitive adhesive, the latter being in contact with a release surface of a release liner or the opposed surface of the backing. The removable pressure-sensitive adhesive is provided at a coat weight of at least 10 gsm and at coat weight ratio to the permanent pressure-sensitive adhesive of at least 1:1.
