A package structure comprises a backing plate supporting a target object, at least one pad disposed on the backing plate and fixing the target object, a frame disposed on a lower side of the backing plate, bonded to the backing plate, and supporting the backing plate to fix the pad onto the backing plate, and a side enclosing plate disposed around the backing plate and connected to the pad to fix the pad. The package structure further comprises a magnetic component disposed on the backing plate and attracting a magnetic coating on the target object.

A panel tray includes: a main body part including outer walls extending in a first direction and a second direction intersecting the first direction and defining a space on a lower surface thereof, a plurality of slots disposed respectively at corners where one sidewall of the outer walls extending in the first direction and another sidewall of the outer walls extending in the second direction meet each other, where the slots include a plurality of guide parts. Each of the guide parts includes a first guide part extending in the first direction, and a second guide part intersecting the first guide part and extending in the second direction, and each of the slots includes an alignment mark defined on an upper surface of one of the first guide part and the second guide part.

A cart and rack assembly for transporting a planar material includes a rack and a cart. The rack includes a frame coupled to a base. The frame has an upper portion and a lower portion. The upper portion has a first width, and the lower portion has a second width. The cart is configured to reversibly receive the base. The cart includes a guide member configured to guide either of the base or the cart into a predetermined position when the base is received by the cart. The assembly further includes a bracket having a first end and a second end which is configured to selectively secure the planar material to the assembly. The base has a series of apertures configured to accept the first end of the bracket. The second end of the bracket is configured to be selectively coupled with the upper portion of the frame.

A container includes: a storage member having a bottom-surface member and a side-surface member; and two protectors disposed at two corners adjacent to each other, the two corners belonging to four corners of a storage space. Each of the two protectors has a support portion detachably fitted in a corresponding one of two cuts, a first reception portion having a first reception surface facing an end surface of a housed object, and a second reception portion having a second reception surface facing an end surface of the housed object. The first and/or second reception portion is integral with the support portion. The second reception portion has, in at least a part adjacent to a bottom surface, an evacuation portion in which a distance between the second reception surface and a side surface of the side-surface member facing the second reception surface increases along with approach to the bottom surface.
