Full-recycling environment-friendly packaging structure

Technical Field

The invention relates to the field of packaging, in particular to a full-recovery environment-friendly packaging structure which is made of environment-friendly materials and is applied to the fields of express delivery, post and logistics.

Background

Referring to fig. 1, in the field of packaging in logistics, express delivery, and postal industry, especially in a packaging structure with a buffer structure, a buffer material a generally adopts a plastic plate and a plastic bubble a1, and the plastic plate and the plastic bubble a1 cannot be directly adhered to the inner wall of a paper packaging structure, and a thermoplastic plastic film B is firstly coated on the inner wall by means of thermoplastic, and then the plastic plate and the plastic bubble a1 are adhered to the plastic film B. In recycling, the plastic sheet, the plastic bubble a1, and the plastic film B need to be torn off from the inner wall, but the plastic film B is extremely thin and difficult to separate, and thus cannot be recycled. For example: a kraft paper bubble bag that generally uses in existing market, its bag body are the kraft paper, have plastic film B at one side of kraft paper, have set up plastic bubble A1 on plastic film B, and the plastic bubble is as buffer material A. The plastic coating B cannot be separated, and the plastic bubble A1 cannot be separated, so that the kraft paper bubble bag cannot be recycled and naturally degraded, and the environment is polluted.

In other cases, as shown in fig. 2, the cushioning material is formed by grinding and cutting other recoverable materials into a powdery and granular soft structure C, and the powdery and granular material is filled as a cushion when the packaging structure is produced. However, the production process and the production process can cause that the powder in the air of the production environment seriously exceeds the standard, the equipment requirement is high, and potential harm is brought to the health of workers.

Referring to fig. 4, in particular, the protective layer 12 includes a liner 13, and the liner 13 is a three-dimensional net structure formed by stretching a die-cut paper 14 made of a paper material, that is, the liner 13 is another form of the die-cut paper 14 after stretching.

In the present embodiment, the die-cut paper 14 is made of the same paper material as that of the first surface 11, and in this case, when the packaging structure 100 is manufactured and the stock is prepared, the paper material of the first surface 11 and the paper material of the die-cut paper 14 can be mixed for use, thereby reducing the stock preparation cost. Of course, depending on the actual requirements and the nature of the articles and the courier being wrapped, different paper materials may be used in other embodiments, such as stronger kraft paper for the first side 11 and plain writing paper for the die cut paper 14.

After the die-cut paper 14 is die-cut, a plurality of rows of die-cut lines 141 are formed, and the interval distance between every two adjacent die-cut lines 141 is the same. Each row of die cut lines 141 includes a plurality of die cut lines 142 spaced apart from each other after die cutting.

The die cutter line 142 is positioned on the die cut line 141 at intervals, that is, the die cutter line 142 is spaced apart from the non-die cut portion and interposed to form a similar intermittent line on the die-cut sheet 14, and the die cutter line 142 is a broken portion of the intermittent line. The die cutting line 142 is stretched to form a die cutting opening 143, the die cutting opening 143 is formed by moving and twisting the edge of the discontinuous portion to the two sides of the die cutting opening 143, the die cutting opening 143 is a three-dimensional polygon, the stretched die-cut paper 14 forms a three-dimensional mesh structure with a plurality of rows of polygonal openings, and the mesh structure is a soft tissue structure and plays a role in protection when being overlapped on the first surface 11.

In another embodiment, as shown in fig. 6, the die-cutting distance between two adjacent die-cutting lines 141 may be different, and it is different according to the strength to be protected, for example, when the planar structure 10 is used for wrapping a fragile product such as glass, a circle of die-cutting lines 141 is required to surround the fragile product, and the interval of the die-cutting lines 141 in the inner planar structure 10 surrounding the fragile product is smaller than the interval of the die-cutting lines 141 in the outer planar structure 10, so that the number of die-cutting times can be reduced as much as possible without reducing the protection strength, and the cost can be reduced.
