Abstract: In a method of ultrasonically bonding paperboard, first and second pieces of paperboard are supplied, with at least one of the first and second pieces of paperboard being provided with a clay coating. The first and second pieces of paperboard are moistened and positioned in a gap between a sonotrode and an anvil of an ultrasonic welding unit. The ultrasonic welding unit is activated and the first and second pieces of paperboard are compressed between 30-70%, more preferably between 40-60%, to cause the clay coating to mobilize and force the clay coating material into fiber matrixes of the first and second pieces of paperboard, followed by cooling of the first and second pieces of paperboard, to bond the first and second pieces of paperboard.

Abstract: A uniformly premixed sealant is extruded into a packaging form and allowed to pressure equilibrate prior to freezing. Upon warming the sealant begins to cure. The storage of the preformed sealant formulation under cold conditions arrests the activity of cure catalysts and accelerators mixed therethrough. The sealant is readily extruded into a preform shape containing a lightweight filler. A release film is provided to avoid contact with the sealant preformed in a shape during application to a substrate.
