Title:
積層体の製造方法
Document Type and Number:
Japanese Patent JP6705299
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a laminate which has an interlaminar strength in a level having no problem in practical applications without an adhesive layer though having a layer formed of a high density polyethylene resin and a layer formed of a polypropylene resin that come in contact with each other.SOLUTION: There is provided a method for producing a laminate in which a layer formed of a polyethylene resin (A) which satisfies specific melt flow rate and density and a melting peak temperature by DSC, and a layer formed of a polypropylene resin (B) which satisfies specific melt flow rate and a melting peak temperature by DSC and is made of a propylene polymer polymerized using a metallocene catalyst come in contact with each other.SELECTED DRAWING: None
