Abstract
Official abstract text for this publication.
A container of a multilayered structure comprising an inner layer and an outer layer of a low-density polyethylene, and an intermediate layer that includes a gas-barrier resin layer and adhesive layers, wherein the adhesive layers contain an acid-modified polyethylene and a propylene resin, the propylene resin being contained in an amount of 0.5 to 10% by weight in the adhesive layers. The container is obtained by using decreased amounts of resins without impairing properties of the containers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A container of a multilayered structure comprising an inner layer and an outer layer of a low-density polyethylene, and an intermediate layer that includes a gas-barrier resin layer and adhesive layers, wherein said adhesive layers contain an acid-modified polyethylene and a propylene resin, said propylene resin being contained in an amount of 0.5 to 10% by weight in the adhesive layers and being one which has not been modified with acid. 2. The container of a multilayered structure according to claim 1 , wherein said adhesive layers, further, contain a linear low-density polyethylene. 3. The container of a multilayered structure according to claim 1 , wherein said acid-modified polyethylene is the one obtained by modifying a linear low-density polyethylene with an acid. 4. The container of a multilayered structure according to claim 1 , wherein said acid-modified polyethylene has a density in a range of from 0.925 to 0.950 g/cm 3 . 5. The container of a multilayered structure according to claim 1 , the container of the multilayered structure being obtained by the direct blow-forming. 6. The container of a multilayered structure according to claim 1 , wherein said propylene resin is a homopolypropylene or a copolymer obtained by copolymerizing a propylene with another α-olefin.
