A shipping system for shipping planar substrates includes a plurality of planar substrates stacked to form a pack and a plurality of interleaving material including substantially spherical beads positioned between the substrates of the pack and configured to carry a load. Substantially all of the beads have a diameter within 25% of D.sub.max, where D.sub.max is a diameter corresponding to a size of an opening of an upper limit sieve used in the shipping system. Also disclosed are a spacer for use in a shipping system for shipping planar substrates, a wrapped system for shipping planar substrates, a method of wrapping a system for shipping planar substrates, and a powder applicator.

A shell for holding one or more products. The shell can comprise a base layer and a barrier layer extending along at least a portion of a face of the base layer, a central wall for receiving at least a portion of the one or more products on an upper side of the central wall, and a stiffening structure extending at least partially around the central wall. The stiffening structure can be configured for resisting bending of at least a portion of the shell toward the upper side of the central wall. The stiffening structure can comprise at least a recess extending along at least a portion of the central wall.

A separation structure includes a support seat having at least one passage defined transversely therethrough. At least two notches are defined from the top of the support seat. Each notch includes a guide portion and a positioning portion. The guide portion opens through the top of the support seat and narrows toward the root portion of the support seat. The positioning portion communicates with the guide portion. The transmission part of a lock is positioned in the positioning portion of the notch via the guide portion. Two operational ends of the lock are located on two sides of the support seat. A user extends his/her finger through the passage to carry the support seat and the locks. The support seats can be piled up to save space.

A cushioning sheet includes: main support parts extending in a reference direction and arranged with at least a part of a wide surface in contact with a first member and a narrow surface facing the wide surface back-to-back in contact with a second member; and a band-shaped connection part connecting the adjacent main support parts and arranged in contact with the first member and at a distance from the second member. A main recess extending in the reference direction and opening toward the first member is formed in a central part of the wide surface of the main support part in a width direction. A sub-recess extending in the reference direction, opening toward at least one of the first member and the second member, and having an opening width smaller than the main recess is formed in a boundary portion between the main support parts and the connection part.
