Full recycling environmental protection packaging structure and manufacturing method thereof

A full recycling environmental protection packaging structure having a planar structure of paper, the planar structure comprising:

• a first surface and a protecting layer overlapped on the first surface;
• the protecting layer comprising multi-layers of liners which are superimposed to form the protective layer with a three-dimensional network structure being formed by paper material being stretched after the paper material is die-cut;
• wherein
• the liner is formed by stretching a die-cutting paper, and a plurality of rows of die-cutting lines is formed by die-cutting the die-cutting paper;
• each row of die-cutting lines comprising a plurality of die-cutting knife lines arranged thereon at intervals after the each row of die-cutting lines is die-cut, so that a die-incision is formed by stretching the die-cutting knife line;
• and wherein
• the packaging structure is sealed so as to form a bag body having an opening;
• and wherein
• the planar structure comprises a second surface so that the protecting layer is clamped between the first surface and the second surface;
• and wherein
• the multi-layers of liners are overlapped by a horizontal and vertical overlapping way that a layout of one row of die-incisions in one layer of liners is perpendicular to a layout of the die-incisions in the other layer of liners, so that positions of the die-incisions after overlapping the multi-layers of liners isn't completely coincide with each other;
• and wherein
• the plurality of die-cutting lines arranged at intervals is straight lines or arc lines parallel to each other, and a distance between every two adjacent die-cutting lines is different so that the space between the two adjacent die-cutting lines of the planar structure surrounding an inner side of a fragile product is less than the space between the two adjacent die-cutting lines of the planar structure surrounding an outer side of the fragile product when the fragile product is surrounded by the planar structure.
