Embodiment

[0035] Table 1 shows four samples, referring to the data of Sample 1 and Examples 1-3, where the topsheet and backsheet laminates were bonded using multiple adhesive tapes. The laminates in all four samples were the same, ie, the bonded material was a backsheet film bonded to an apertured topsheet film, for use as eg a wing laminate. The adhesive used for all four samples was the same. All four samples have the same area of ​​190 x 48, or 9,120mm 2 .

[0036] For the reference sample, the adhesive was applied in a continuous layer covering the entire area of ​​the sample at a spot basis weight of 13 gsm. This yielded 0.119 g of adhesive. Using the Standard Test Method for Peel Resistance of Adhesives, with modifications (described below), the resulting bond strength yields an adhesive bond strength of 1.0 N / 15mm.

[0037] For Examples 1-3, 50% of the area was coated with adhesive tape using a 1-to-1 slot adhesive pattern. The adhesive strips had a lateral width of 1 mm an...

Abstract

An article having a longitudinal axis and a lateral axis, the article comprising a topsheet and a backsheet, wherein the topsheet comprises an apertured film and the backsheet comprises a film, wherein the topsheet film and the backsheet film are bonded via a plurality of adhesive stripes.

Description

technical field [0001] Absorbent articles are disclosed comprising film laminates bonded with adhesive tapes. Background technique [0002] Absorbent articles comprise a plurality of components, usually layers of materials bonded together. Article components can be bonded in a variety of ways, but most bonds are via adhesives. One difficulty with using adhesives is the challenge of balancing the proper application level of adhesive to achieve adequate bond strength with cost and with preventing processing issues such as adhesive burn through in the case of thin films. [0003] Simply put, the more adhesive you use, the stronger the adhesive bond. While many variables can exist, the strength of a particular adhesive bond between two materials can be roughly proportional to the amount or thickness of adhesive used. Reducing the amount of adhesive used can reduce costs and reduce processing problems, but there is an increased risk that the bond will not be strong enough. Ac...
