HEAT SHRINKABLE MULTILAYER FILM |
摘要 |
<p>Disclosed is a heat shrinkable multilayer film obtained by at least uniaxially stretching a multilayer film which comprises outer layers mainly composed of a block copolymer resin (a) composed of a vinyl aromatic monomer and a conjugated diene monomer, and an intermediate layer mainly composed of a resin (c) wherein a component made from a rubber elastic body (b) is contained in the form of dispersed particles in a continuous phase of a styrene polymer which is composed or a vinyl aromatic monomer and an n-butyl acrylate. The rubber plastic body (b) is a block copolymer composed of 20-45% bey weight of a vinyl aromatic monomers and 80-55% by weight of a conjugated diene monomer, and the rubber elastic body (b) content in the resin (c) is 3-20% by weight. The resin composition of the continuous phase of the resin (c) is composed of 78-93% by weight of a vinyl aromatic monomer and 22-7% by weight of an n-butyl acrylate, and the resin (c) has a Vicat softening temperature of 60-85°C.</p> |
