ELASTIC SINGLE LAYER FILM AND MANUFACTURING METHOD OF LAMINATE FOR DISPOSABLE HYGIENE PRODUCTS

摘要

PROBLEM TO BE SOLVED: To provide a single layer film having sufficient tensile strength in a manufacturing direction for processing and good elastic property in a lateral direction thereto in thickness which is reduced as much as possible.SOLUTION: There is related an elastic single layer film having thickness of a layer of 20 to 100 μm and containing 35 to 90 wt.% of an asymmetric styrene-diene-triblock copolymer as a first polymer material A and a second polymer material B. There is provided polystyrene of 8 to 40 wt.% as the second polymer material B.SELECTED DRAWING: Figure 1
