The present invention relates to a seedling tray packing case having improved fixing force, and to a packing method thereof. More specifically, the seedling tray packing case (1) comprises: a body (10) having an open top, having an insertion space (11) formed therein, and having penetration grooves (13) respectively formed in both sides thereof a tray (20) selectively inserted in the insertion space (11) a bending member (30) having both end parts discharged to the penetration grooves (13) by passing through the top of the tray (20), and tied in the outside of the body (10) to fix the tray (20) and the body (10) and a cover unit (40) for covering the top of the body (10). The tray (20) is inserted in the insertion space (11) of the body (10), and the bending member (30) comes in contact with the top side of the tray (20). Then, both ends thereof are discharged to the penetration grooves (13), and the ends of the bending member (30) are tied and fixed at the bottom of the body (10). The cover (40) is covered and packed at the top of the body (10). A simple structure and a simple packing method are ensured, so production can be conveniently performed and packing can be rapidly performed. Thus, convenience is imparted. After the tray (20) in which a seedling is planted is laminated, the bending member (30) is completely fixed, so the seedling can be safely transported to a consumer from a cultivation land. Also, damage to a seedling (plant) can be fundamentally blocked, so reliability can be improved among consumers.COPYRIGHT KIPO 2017본 발명은 고정력을 향상시킨 묘목 트레이 포장케이스 및 그 포장방법에 관한 것으로서, 더욱 자세하게는 상부가 개방되며 내부에 삽입공간(11)이 형성되고, 양측에 관통홈(13)이 각각 형성되는 본체(10) 상기 삽입공간(11)에 선택적으로 삽입되는 트레이(20) 상기 트레이(20)의 상부를 지나 양측끝부가 상기 관통홈(13)으로 배출되어 본체(10)의 외측에서 묶여져 트레이(20)와 본체(10)를 고정하는 벤딩부재(30) 상기 본체(10)의 상부를 덮는 덮개부(40) 로 구성되는 포장케이스(1)를 이용하여 상기 본체(10)의 삽입공간(11)에 트레이(20)를 삽입하고, 상기 벤딩부재(30)를 트레이(20)의 상측과 맞닿게 한 후 양측 끝부를 관통홈(13)으로 배출시켜 본체(10)의 하부에서 벤딩부재(30)의 각각의 끝부를 묶어 고정하며, 상기 덮개(40)를 본체(10)의 상부에 덮어
