Abstract

The invention relates to a packing material. The packing material comprises a top surface part, a main body part and a bottom surface part; a first transverse crease line is pressed between the top surface part and the main body part, and a second transverse crease line is pressed between the bottom surface part and the main body part; pairs of longitudinal crease lines are pressed on the main body part; first oblique crease lines are pressed between the longitudinal crease lines and the first transverse crease line, and second oblique crease lines are pressed between the longitudinal crease lines and the second transverse crease line; each pair of longitudinal crease lines and the first oblique crease line and the second oblique crease line at the two ends of the pair of longitudinal crease lines define an auxiliary wall plate; the first transverse crease line, the second transverse crease line, two longitudinal crease lines of corresponding adjacent pairs, and the first oblique crease lines and the second oblique crease lines at the two ends of the two longitudinal crease lines of adjacent pairs define a main wall plate; and the longitudinal crease lines, the first oblique creaselines and the second oblique crease lines are formed by pressing the inner side surfaces of a support layers downwards. The packing material has the advantages of being easy to form in the process ofbeing manufactured into a packing container, and the manufactured packing container is full in appearance and high in holding strength.

Description

technical field [0001] The invention relates to a packaging material, especially a packaging material with a supporting layer.
