Molded body, method of producing the same, and recycling method

A method of producing a molded body, the method comprising:

• disposing a first support layer and a third support layer in a state where the first support layer and the third support layer are spaced apart from each other and face each other,
• the first support layer being formed of a first resin composition, and the third support layer being formed of a third resin composition;
• interposing a second resin composition provided with foamability in a gap between the first support layer and the third support layer;
• and
• forming an intermediate layer by expanding the gap while causing the second resin composition to foam, and thereby producing a molded body including a design layer, the intermediate layer, and a back layer laminated in this order, the design layer being a non-foamed layer formed by the first support layer, the intermediate layer being a foamed layer, and the back layer being a non-foamed layer formed by the third support layer,
• wherein:
• the first resin composition is a newly produced resin composition including a polyolefin, a polyamide, and a polyolefin-based modified elastomer having a reactive group that reacts with the polyamide,
• the second resin composition is a polyolefin-based recycled resin composition,
• the third resin composition is the same as the first resin composition, the same as the polyolefin-based recycled resin composition, or a newly produced polyolefin, and
• the first resin composition, the second resin composition, and the third resin composition include a polyolefin in an amount of 50 mass % or more based on a total mass of each resin composition, and
• the design layer is free of the polyolefin-based recycled resin composition.
