According to the present invention, a base member is manufactured of a material, which is lighter than an existing rear package tray made through injection molding, and then, a surface layer, which feels like the injected rear package tray, is integrated with the base member, so a rear package tray of the present invention can be lighter than the injected rear package tray as well as feeling like the injected rear package tray. In particular, since thermoplastic olefin (TPO) and polypropylene (PP) foam are used for the base member, the rear package tray can be low-cost and reusable, and predetermined rubber contained therein can create a nice touch and increase a sound-absorption effect. Moreover, the rear package tray is light because the base member is made of TPO and PP, which increases vehicle fuel efficiency through the reduction in weight, while providing sufficient durability required for rear package trays.

    본 발명은 사출 방식의 리어 패키지 트레이보다 가벼운 재질로 기재를 제작하고, 이 기재에 사출로 제작한 리어 패키지 트레이와 같은 느낌을 든 표층을 일체로 구성하므로, 기존 사출 방식의 리어 패키지 트레이보다 가벼우면서도 사출한 리어 패키지 트레이와 같은 느낌을 느낄 수 있게 한다. 특히, 본 발명은 기재로 TPO(Thermoplastic Olefin)와 PP(Polypropylene) 폼을 이용하므로, 가격이 저렴하면서도 재사용할 수 있고, 소정의 고무를 함유하고 있어 촉감이 좋을 뿐만 아니라 흡음 효과도 높일 수 있게 한다. 또한, 본 발명은 TPO와 PP로 이루어진 기재를 통해 가벼우면서도 리어 패키지 트레이에서 요구하는 내구성을 충족하게 하면서도 중량 감소를 통해 자동차 연비를 늘릴 수 있게 한다.
