Abstract
Provided is an ultrasmall-sized fixing tape suitable for a disposal tape for an absorbent article, such as a disposable diaper, a sanitary napkin, or an incontinence pad. The ultrasmall fixing tape of the present invention includes: an extending portion; and a non-extending portion that is substantially free from extending, in which: the non-extending portion includes securing means in at least part thereof; the ultrasmall fixing tape has a base material layer B; the base material layer B has a thickness of 50 μm or more; and the base material layer B has an upper yield strength in a longitudinal direction thereof at a temperature of 23° C. and a humidity of 50% of from 5 N/25 mm to 15 N/25 mm.
Claims25
A fixing tape, comprising:
- a base material layer, that includes:
- an extending portion;
- and
- a non-extending portion connected to an end of the extending portion and that is substantially free from extending, wherein
- the non-extending portion includes an adhesive in at least part thereof,
- the base material layer comprises a stretchable laminate including an elastomer layer and an olefin-based resin layer arranged on at least one side of the elastomer layer,
- the base material layer has a thickness that is from 50 μm to 125 μm,
- the base material layer has an upper yield strength in a longitudinal direction thereof at a temperature of 23° C. and a humidity of 50% of from 5 N/25 mm to 15 N/25 mm, and
- the base material layer has a permanent strain amount of 30% or less when the base material layer is extended in the longitudinal direction at an extension percentage of 400% and then returned to a steady state, subsequently extended in the longitudinal direction at an extension percentage of 100% and then returned to the steady state, and further extended in the longitudinal direction at an extension percentage of 100% at a temperature of 23° C. and a humidity of 50%.
