Abstract: A strap-based variable modular cushioning material for being tied on an object includes at least one strap and at least one block. The strap is formed with a plurality of through holes and can be wound around the object. The block is mad of elastic material, has at least one side concavely formed with a groove, and can deform and be inserted into at least one of the through holes of the strap to couple the block with the strap. When the block and the strap are coupled together, the inner wall of the through hole corresponds to the groove in position, and a top portion and a bottom portion of the block are exposed from the strap. When the strap is coupled with a plurality of blocks, each two adjacent blocks are separate from each other by a distance.

Abstract: An anti-collision packing object includes at least one base portion and at least one elastic composite structure that can be connected to the base portion and includes at least one main body and at least one reinforcement structure. The main body can made of a low-density foam material having a density lower than 30 kg/m3. The reinforcement structure can be made of a paper material, a plastic material, a softwood material, etc., and can be placed in the main body, so that the structural strength of the low-density foam material is enhanced to allow a higher vertical compressive strength for the elastic composite structure and to provide better cushioning effects and supporting strength.
