Abstract

The utility model discloses a packaging material, including the panel body, the panel body comprises upper surface cardboard, lower surface cardboard and the honeycomb core that has honeycomb between being located upper surface cardboard and the lower surface cardboard, and the panel body has at least one and has elastic recessed area, at least one has elastic recessed area and treats the profile adaptation of packing material. The packaging material provides better transport protection for fragile articles through the cushioning properties of the packaging material.

Description

Packaging material

The technical field is as follows:

the utility model relates to a packaging material field is a packaging material particularly.

The background art comprises the following steps:

the conventional honeycomb panel is a three-layer composite sandwich structure, as shown in fig. 2, and is composed of an upper surface paperboard 1, a lower surface paperboard 2 and a honeycomb support core. The support core, also referred to as honeycomb core panel 3, is structured to resemble a honeycomb structure and is made of cardboard, resin-impregnated paper, fibre plastic or the like, the face sheets may be made of cardboard, plastic, fibre composite or metal sheets or the like, and the support core and the face sheets are usually glued together.

Such structures, especially paper honeycomb panels, are used as intermediate layers in many industrial fields to prevent transport and storage damage. Paper honeycomb panels have the advantage that they are light and stable, completely recyclable, since they are made of 100% paper and water-soluble glue, easy to handle safely, have high compressive strength, in particular high weight, and high energy absorption. They are designed for re-use and do not suffer injury from nails or splinters. The paper honeycomb panels can be manufactured in any desired size and shape and can therefore be used in many areas of logistics and storage, such as filling empty spaces and buffers, as filling material in the furniture, window and door industries, as intermediate for transporting and storing layers of various products.

However, in general, such a paper honeycomb board is generally a planar structure, and its applicability is limited.

The utility model has the following contents:

the utility model aims to solve the technical problem that a have elastic packaging material is provided, thereby this packaging material is convenient for the holding on the basis of paper honeycomb panel and treats the packing material and play better protection, simultaneously, provides better transportation protection for fragile article through packaging material's buffer characteristic.

The technical solution of the utility model is, provide a packaging material, including the panel body, the panel body comprises upper surface cardboard, lower surface cardboard and the honeycomb core that has honeycomb between being located upper surface cardboard and the lower surface cardboard, and the panel body has at least one and has elastic sunk area, at least one has elastic sunk area and treats the profile adaptation of packing material. Through setting up the depressed area, can be used for the corresponding packing article of treating of holding to more do benefit to the packing protection.

Preferably, the at least one depressed region having elasticity is formed by local mechanical pressing at the panel body, wherein the at least one depressed region having elasticity is designed to be introduced onto the upper surface paperboard from above the panel body or to be introduced onto the lower surface paperboard from below the panel body to damage the honeycomb structure of the corresponding region. Because the paper honeycomb structure in the concave area of the panel body is damaged, the honeycomb core board has elastic elasticity instead of rigidity and pressure resistance in the areas, so that articles accommodated in the honeycomb core board can be better protected, particularly fragile articles such as mobile phones and flat plates. The recessed regions have a shape, for example they may be in the form of grooves, the resilient nature of which can absorb impact forces and thereby protect the articles therein from breakage during transport. The recessed region may be formed in other shapes, for example, the recessed region may be a circle, an ellipse, a triangle, a square, a polygon, or the like.

Furthermore, the number of the panel bodies is two, wherein the at least one elastic concave area of one panel body is introduced from the upper part of the panel body to the upper surface paperboard and is pressed downwards to form a downward groove, the other panel body is introduced from the lower part of the panel body to the lower surface paperboard and is pressed upwards to form an upward groove, the downward groove corresponds to the upward groove, and a cavity formed by matching the downward groove and the upward groove is used for accommodating a to-be-packaged object. The packing material is treated to two wrapping materials about the accessible and is packed the protection, and the effect is better.

Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: because the paper honeycomb structure in the recessed areas of the panel body is damaged, the honeycomb core board no longer has rigidity and pressure resistance in the areas, but has elastic elasticity, so that articles accommodated in the honeycomb core board can be better protected.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic structural diagram of the prior art.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings and detailed description:

as shown in figure 1, the packaging material comprises a panel body, wherein the panel body consists of an upper surface paper board 1, a lower surface paper board 2 and a paper honeycomb core board 3 which is positioned between the upper surface paper board 1 and the lower surface paper board 2 and has a honeycomb structure, the panel body is provided with at least one elastic concave area 4, and the concave area 4 is matched with the outline of a to-be-packaged object. In this embodiment, the object to be packaged is a glass strip, the recessed area extends in the width direction of the whole panel body, and the length of the recessed area is consistent with the length of the glass strip.

The recessed areas are formed by local mechanical pressing on the panel body, wherein the recessed areas are introduced onto the upper surface paperboard from above the panel body and are pressed downwards mechanically to damage the honeycomb structure of the corresponding area. Because the paper honeycomb structure in the recessed areas of the panel body is damaged, the honeycomb core board no longer has rigidity and pressure resistance in the areas, but has elastic elasticity, so that the glass strips accommodated in the honeycomb core board can be better protected. Of course, a plurality of recessed areas can be arranged on one panel body at intervals to place a plurality of glass strips, and then a plurality of panel bodies are stacked and stacked, boxed and packaged for transportation. It should be noted that the depth of the recessed area can fully accommodate the package.

As an improved embodiment, the concave area can be designed by two panel bodies which are arranged correspondingly up and down, namely, the concave area of one panel body is introduced from the upper part of the panel body to the upper surface paperboard and pressed downwards to form a downward groove, the other panel body is introduced from the lower part of the panel body to the lower surface paperboard and pressed upwards to form an upward groove, the downward groove corresponds to the upward groove, and a cavity formed by matching the downward groove and the upward groove is used for accommodating the object to be packaged.

The foregoing is illustrative of the preferred embodiments of the present invention only and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
