As shown in <FIG>, the structure of the buffer packaging layer is further explained in another aspect of this application, wherein the buffer package <NUM> of the buffer packaging layer is uniformly formed on the base layer <NUM>.

By providing double buffer protection through the first buffer layer 20A and the second buffer layer 20B of the buffer package <NUM>, the buffering and supporting effect can be improved.

It can be understood that when two buffer pack layers are relatively arranged, a buffer package <NUM> of one buffer pack layer can be positioned in alignment within the gap space <NUM> of another buffer pack layer, so that the two buffer pack layers can be aligned with each other. It can be understood that two aligned buffer pack layers can provide buffering and support in two directions (from the front and back of the base layer <NUM>).

The packaging paper includes an inner layer <NUM>, an outer layer <NUM>, and at least one packaging buffer layer <NUM> set between the inner layer <NUM> and the outer side <NUM>. The structure of the packaging buffer layer <NUM> is the same as that in any of the preferred embodiments mentioned above and will not be repeated here.

The top of the buffer package <NUM> of the packaging buffer layer <NUM> is adhered to the inner side of the inner layer <NUM> or the inner side of the outer layer <NUM>, and the spacing space <NUM> of the packaging buffer layer <NUM> is sealed by the inner layer <NUM> or the outer layer <NUM>, thereby forming a sealed gas storage structure. Correspondingly, the base layer <NUM> of the packaging buffer layer <NUM> is adhered to the inner layer <NUM> or the outer layer <NUM> for sealing, thereby forming a sealed gas storage structure.

It can be understood that when the packaging buffer layer <NUM> of the packaging paper is multi-layered, a plurality of buffer structure is formed by the packaging buffer layer <NUM>. As shown in <FIG>, in this preferred embodiment of the present application, the packaging buffer layer <NUM> of the packaging paper further comprises a first buffer layer 300a and a second buffer layer 300b. The first buffer layer 300a and the second buffer layer 300b have the same structure, and the first buffer layer 300a and the second buffer layer 300b are relatively positioned. The buffer packages <NUM> of the first buffer layer 300a corresponds to the gap space <NUM> of the second buffer layer 300b, and the buffer packages <NUM> of the first buffer layer 300a is set inside the gap space <NUM> of the second buffer layer 300b.

The base layer 10a of the first buffer layer 300a and the base layer 10b of the second buffer layer 300b of the packaging buffer layer <NUM> are adhered between the inner layer <NUM> and the outer layer <NUM>. It should be understood that in this preferred embodiment of the present application, the double-layer structure of the packaging buffer layer <NUM> provides a buffering effect from the inner layer <NUM> and the outer layer <NUM>.

The size of the buffer package 20c in the inner buffer layer 300c is smaller than the size of the buffer package 20d in the outer buffer layer 300d. Therefore, when the inner buffer layer 300c and the outer buffer layer 300d are aligning, the buffer package 20c of the inner buffer layer 300c is nested inside the buffer package 20d of the outer buffer layer 300d.

In the preferred embodiment of the present application, the inner layer <NUM> is positioned on one side of the inner buffer layer 300c of the packaging buffer layer <NUM>, while the outer layer <NUM> is positioned on one side of the outer buffer layer 300d, wherein the inner buffer layer 300c and the outer buffer layer 300d of the packaging buffer layer <NUM> are stacked on top of each other.

In the preferred embodiment of the present application, the inner buffer layer 300c and the outer buffer layer 300d of the packaging buffer layer <NUM> are adhesively bonded to form a double-layer buffer structure, wherein the inner layer <NUM> is adhesively bonded to the base layer <NUM> of the inner buffer layer 300c, and the outer side <NUM> is adhesively bonded to the top of the outer buffer layer 300d. Thus, the packaging buffer layer <NUM> forms a double air chamber structure, namely an inner air chamber <NUM> formed by the inner buffer layer 300c and the inner layer <NUM>, and an outer air chamber <NUM> formed by the inner buffer layer 300c and the outer buffer layer 300d, forming a dual air chamber buffer structure of the packaging buffer layer <NUM>.
