The present invention relates to an eco-friendly elastic packaging material capable of securing pores therein. According to the present invention, an eco-friendly elastic packaging material capable of securing pores therein has eco-friendly urethane balls coated with thermoplastic polyurethane-made bonding films concentrating the urethane balls coated therewith, wherein the urethane balls are firmly bonded to each other when the contact portions of the bonding films coated on the different urethane balls are bonded to each other, so the noncontact portions of the bonding films coated on the different urethane balls can naturally have the pores to secure smooth drainage and ventilation, thereby solving various problems generated when the drainage and the ventilation are not performed in an existing elastic packaging material. In addition, according to the present invention, the urethane balls and the bonding films can be conveniently recovered and recycled after completely used because manufactured from the thermoplastic polyurethane, thereby effectively reusing resources. Furthermore, according to the present invention, in contrast with the existing elastic packaging material, the eco-friendly elastic packaging material not required to use a solvent does not emit substances harmful to a human body, so the eco-friendly elastic packaging material can be more eco-friendly, and can be safe for the human body compared with the existing elastic packaging material. |
