Abstract

The present invention addresses the problem of providing: a molded article equipped with a repeatedly movable part having both of fatigue resistance and mechanical strength; and a method for producinga molded article, whereby it becomes possible to improve the flexibility of designing of a mold and the flexibility of the shape of the molded article and also it becomes possible to reduce the number of steps. The molded article is equipped with a repeatedly movable part 15 which can be bent or curved repeatedly, wherein the repeatedly movable part 15 is formed from a thermoplastic resin composition containing a polyolefin resin, a polyamide resin and a modified elastomer having a group reactive with the polyamide resin. The method is a method for producing a molded article equipped with a repeatedly movable part that can be bent or curved repeatedly, said method being characterized in that a thermoplastic resin composition containing a polyolefin resin, a polyamide resin and a modifiedelastomer having a group reactive with the polyamide resin is used as a molded material for the repeatedly movable part.

Description

technical field

[0001] The invention relates to shaped bodies and methods for their production. In more detail, it is related with the molded object which has a repeating movable part, and its manufacturing method. Background technique

[0002] In recent years, for example, a resin product in which a hinge is integrally molded with other parts is known. Specifically, there can be mentioned a resin product having a hinge connecting the container and the lid, and the hinge is integrally formed with the container and the lid. Among such resin products, polyolefin resins of hinge-moldable grades in which fatigue resistance and moldability are obtained in a relatively balanced manner are often used.

[0003] In addition, the following patent documents 1-4 are known as a mixed resin containing a polyolefin resin and a polyamide resin.
