<p>Disclosed is a packing pack. It comprises a first secondary material sheet provided on a valve film, a second secondary material sheet provided on the opposite side of the valve film with respect to the first secondary material sheet to face the first secondary material sheet, and being shorter than the first secondary material sheet, a middle air packet formed by a packing film in contact with the valve film on which the second secondary material sheet is provided and charged with air by receiving air through the second secondary material sheet, and an air charging portion formed between the valve films by a third secondary material sheet perpendicular to the first secondary material sheet and disposed between two rows of air pockets. The packing pack can reduce raw material cost by effectively using a middle portion of the packing pack because two outer rows of air pockets and middle air pockets are formed in a single air supply step, and can enhance packing efficiency because three air pockets are formed at one time. Further, it can be formed to have a variety of shapes because the sizes of the outer air pockets and the middle air pockets can be individually adjusted. Thus, the packing pack can be used to pack objects having a variety of shapes. Also, it can reduce air leakage because the middle air pockets clog the air charging portion, in which air leakage is generally caused.</p> |
