スチック容器である。2. Description of the Related Art Conventionally, there is a technique disclosed in Japanese Patent Application Laid-Open No. 2-215529 as an attempt to improve the surface gloss of a plastic laminated container for storing shampoo and the like. The technique uses an outermost surface layer with an ethylene content of 2 to 8% by weight and a melt flow rate of 2.5%.
This is a multilayer plastic container formed of an ethylene-propylene random copolymer having a gw / Mn ratio of 3 to 5 or more for g / 10 minutes or more.

(Mitsui Petrochemical), low-density polyethylene DND2450 (manufactured by Nippon Unicar) was used as the intermediate layer 3 and the surface layer 4, and 1.8% by weight of pearl essence and an appropriate amount of green pigment were blended into the intermediate layer 3 and blown. It was molded to obtain a container 1. The thickness of each layer of the container 1 is 900 μm for the inner layer,
The intermediate layer was 50μ and the surface layer was 50μ. The material of this container 1
Sample A was cut into a plate of 15 × 60 mm. Sample B was prepared in the same manner as Sample A, except that a pink pigment was used. The gloss of these samples A and B was measured at an incident angle of 60 ° using a gloss meter, and as a result, both were 58.
