<p>PURPOSE: A film essentially consisted of metallocene, containing more than one mixture made up of polyamide and polyethylene and selectively a polyethylene layer is provided. CONSTITUTION: A film contains more than mixture layer(A) made up of polyamide and metallocene polyethylene and more than one polyethylene layer(B) consisted of metallocene polyethylene. In addition, the film contains the polyethylene layer between two layers of the mixture made up of polyamide and metallocene polyethylene. The film contains more than one layer(A) of a mixture made up of polyethylene and polyamide, not metallocene and more than one layer(A) of metallocene polyethylene. Herein, the thickness of the layer(A) is 5 to 150 micrometer, and metallocene polyethylene has Mw/Nn less than 3, desirably 2.</p> |
