Abstract

Stretch laminate hot melt adhesives and stretch laminates are described. The stretch laminate hot melt adhesives are suitable for adhering elastic materials with inelastic substrates, and allow permanent deformation of the inelastic substrate and extensions and retractions of the elastic materials. The stretch laminate hot melt adhesive is particularly suitable for back ear lamination for disposable absorbent articles.

Description

technical field [0001] The present invention discloses stretchable laminates and absorbent articles comprising stretchable laminates comprising hot melt adhesives which are especially suitable for stretching laminates. Background technique [0002] Disposable absorbent diapers are widely used by infants and incontinent patients. In order to provide disposable absorbent diapers that can fit a range of wearers and minimize leakage, disposable absorbent diapers often include stretch laminates. Because disposable absorbent diaper wearers vary in size, conventional stretch laminates are often used in the waist and leg regions of disposable absorbent diapers to allow the disposable absorbent diaper to fit a wide range of wearers. [0003] Conventional stretch laminates often have at least two nonwoven materials and at least one elastic film sandwiched between the two nonwoven materials. Generally, the two nonwovens are attached to the elastic film via an adhesive. [0004] In o...
