Abstract: A non-contact method of joining two components via direct heating of a thermoset adhesive includes applying the thermoset adhesive to at least a first component of the two components. The thermoset adhesive includes a susceptor to reacts in the presence of an electromagnetic field. The method includes placing the first component and a second component of the two components in proximity to an electromagnetic field. In some aspects, the method includes placing the first and second components in proximity to an electromagnetic field of a capacitor. The susceptor interacts with the electromagnetic field to heat the thermoset adhesive via resistive heating. In some aspects, a method of direct-contact heating of the thermoset adhesive includes attaching electrodes to a film comprising the adhesive. The components being joined together are not directly heated by the electromagnetic field, and as a result experience much lower temperatures than the thermoset adhesive.

For example, two separate webs or film layers of material can be made with two or more different layers of films combined to provide different necessary benefits in manufacturing or forming the valve and sealing to a pouch or package later.

The pocket is formed on both of the two individual forming webs or film layers at the same time. A separate lidding web or layer of material is introduced and sealed over the underside of the bubble pocket to trap air or gas between the lidding layer and the combined individual forming webs or film layers.

Abstract: In a production method of an elastic composite sheet, the elastic member does not break when the elastic member, in a stretched state, is bonded to a base material sheet; an elastic composite sheet and a disposable wearable article use the elastic composite sheet. A strip-shaped or string-shaped elastic member composed mainly of a thermoplastic elastic resin is stretched in the longitudinal direction of the elastic member. The stretched elastic member is placed over a first base material sheet such that the main surface of the first base material sheet contacts the elastic member. In this state, the elastic member and the first base material sheet are bonded in a first position that overlaps the elastic member seen from a direction perpendicular to the main surface of the first base material sheet and that is away from the edges of the elastic member.
