A resin composition includes: a polyamide resin (A); an ionomer of an ethylene-unsaturated carboxylic acid-based copolymer (B); and an ethylene-based polymer (C), wherein a content of the polyamide resin (A) is 50% by mass or more with respect to a total amount of the polyamide resin (A), the ionomer of an ethylene-unsaturated carboxylic acid-based copolymer (B) and the ethylene-based polymer (C), and wherein a content of the ethylene-based copolymer (C) is less than 50% by mass with respect to a total amount of the ionomer of an ethylene-unsaturated carboxylic acid-based copolymer (B) and the ethylene-based polymer (C).

Resin composition and molded body

A resin molding apparatus of a simplified structure is provided that offers high handling efficiency by a work robot, thereby improving a throughput. The resin molding apparatus () that retains a hollow molded body () including a closed-bottom cylindrical main body () and a cylindrical open neck portion (), the open neck portion () including a helical ridge portion () formed on an outer circumferential surface thereof and divided into a plurality of helical segments by a slit () extending in an axial direction of the open neck portion (), and that overmolds a resin sheathing body () on an outer surface of the main body (), includes a first recess in which the open neck portion () is to be fitted, and a rib () formed on a circumferential surface of the recess so as to extend in a depthwise direction thereof, and to be engaged with the slit ().

Resin molding apparatus, resin molding method, and resin container

A synthetic resin hollow body (A) that has a satisfactory decorating property and a satisfactory recycle property in a disposal and that is hardly damaged. In addition, a product cost and an operation cost thereof can be suppressed. The synthetic resin hollow body (A) includes: a hollow molding body (a) made of a resin, the hollow molding body (a) capable of holding a liquid material; and a resin sheathing body formed outside the hollow molding body (a) in an integrating manner with the hollow molding body (a), wherein the resin sheathing body is made of a highly transparent synthetic resin having a total ray transmittance of at least 80%.

Synthetic resin hollow body

A synthetic resin hollow body which includes a hollow molding body made of a resin, the hollow molding body capable of holding a liquid material, and a resin sheathing body formed outside the hollow molding body in an integrating manner with the hollow molding body, wherein the resin sheathing body is made of a highly transparent synthetic resin having a total ray transmittance of at least 80%. The synthetic resin hollow body can exhibit a satisfactory decorating property and a satisfactory recycle property and is hardly damaged. In addition, the product cost and operation cost can be suppressed.

A manufacturing method of a synthetic resin hollow body in which a molten resin is injected for an over-molding outside a hollow molding body made of a resin provided with a hollow body and at least an opening portion to form a resin sheathing body in an integrating manner with the hollow molding body. The method includes the step of injecting the molten resin for an over-molding under the state in which the hollow molding body is partially or wholly filled with a fluid substance. The manufacturing method of a synthetic resin hollow body is capable of suppressing resin cost and operation cost and can improve decorating property.
