Abstract: An exemplary packing case (10) for substrates includes a main body (12), at least one buffer (14) and a cover (11). The cover is configured for attaching onto the main body. The main body includes a bottom plate (121) and a plurality of side walls (122) substantially perpendicularly extending from the bottom plate. The bottom plate and the side walls form an accommodating space. An inner surface of at least one of the side walls includes a plurality of first latching members. The at least one first buffer includes a plurality of second latching members. The second latching members and the first latching members of the at least one side wall have complementary shapes such that the at least one first buffer is detachably engagable with the at least one side wall thereby adjusting a capacity of the accommodating space.

Abstract: An exemplary packing apparatus includes a main body (201), a cover (202), and a partition layer (212). The cover is configured to be attached to the main body and cooperatively forms a receiving space with the main body. The partition layer is received within the receiving space.
