Abstract

The utility model discloses a degradable environmental protection kraft paper board, including surface course and the refill that the inboard extension board width direction interval of complex in the surface course set up to vacuole formation between each refill, and set up the buffering and pack in the cavity. The degradable environment-friendly kraft paper board of the utility model is provided with the paper cores arranged at intervals to form the cavity, so that the buffering capacity can be increased, and the cavity is arranged to facilitate the subsequent degradation; the width of the second buffer paper core is smaller than that of the first buffer paper core, so that the second buffer paper core plays a role of a fulcrum between the two first buffer paper cores, the compression strength of the paperboard can be ensured while the buffer performance is ensured, and the surface layer is prevented from being deformed and damaged greatly; the thickness of the reinforced paper core is smaller than that of the paper core so as to leave a buffer space and a cavity, thereby facilitating subsequent filling.

Description

Degradable environment-friendly kraft paper board

Technical Field

The utility model relates to a cardboard technical field especially relates to a degradable environmental protection kraft paper board.

Background

The paperboard is also called as paperboard, is a thick paper sheet formed by interweaving fibers and processed by various paper pulps, is widely applied in life, is convenient to correspondingly package and use, and is light in weight and convenient to carry, assemble and use.

The common paper board is prepared by animal fibers such as wool and the like or mineral fibers such as asbestos and the like, and is not easy to degrade and use; meanwhile, the strength and the cushioning performance of the paperboard are all deficient.

SUMMERY OF THE UTILITY MODEL

The present invention aims at solving at least one of the technical problems in the related art to a certain extent. Therefore, an object of the utility model is to provide a degradable environmental protection kraft paper board, for the composite construction cardboard, the material chooses for use easily degradable material, and simultaneously, the cardboard has higher cushioning nature and intensity.

The technical scheme of the utility model as follows:

the utility model provides a degradable environmental protection kraft paper board, includes surface course and the compound refill that sets up at the inboard extension cardboard width direction interval of surface course to at vacuole formation between each refill, and set up the buffering and fill in the cavity.

Furthermore, the surface layer and the paper core are both made of commercially available degradable kraft paper.

Further, the buffer filling is a buffer paper pad.

Further, the refill includes first buffering refill and second buffering refill, first buffering refill and second buffering refill equidistant setting.

Further, the width of the second buffer paper core is smaller than that of the first buffer paper core.

Further, the first buffer paper core and the second buffer paper core are corrugated paper cores or honeycomb paper cores.

Furthermore, a reinforced paper core is arranged in the middle of the adjacent paper cores.

Furthermore, the reinforced paper core is in a local covering shape.

Further, the thickness of the reinforced paper core is smaller than that of the paper core.

The utility model provides a beneficial effect: the paper cores are arranged at intervals to form a cavity, so that the buffering capacity can be increased, and the cavity is arranged for subsequent degradation; the width of the second buffer paper core is smaller than that of the first buffer paper core, so that the second buffer paper core plays a role of a fulcrum between the two first buffer paper cores, the compression strength of the paperboard can be ensured while the buffer performance is ensured, and the surface layer is prevented from being deformed and damaged greatly; the thickness of the reinforced paper core is smaller than that of the paper core so as to leave a buffer space and a cavity, thereby facilitating subsequent filling.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1, a degradable environmental protection kraft paper board, includes surface course 1 and the compound refill that sets up at surface course 1 inboard extension cardboard width direction interval to form cavity 4 between each refill, set up cavity 4 multiplicable buffer capacity, and set up buffering and fill 5 in the cavity 4.

Surface course 1, refill all adopt the degradable kraft paper of market to make, simultaneously, cavity 4's setting is also convenient for follow-up degradation.

The surface layer 1 can be a box board or a three-layer composite corrugated structure, and the strength is guaranteed.

Considering green environmental protection nature, buffering 5 is filled and is chooseed buffering paper pad for use, directly packs to cavity 4 in, uses more green convenient.

In addition, in this embodiment, the refill includes first buffering refill 2 and second buffering refill 3, first buffering refill 2 and second buffering refill 3 equidistant setting, and the width of second buffering refill 3 is less for second buffering refill 3 plays the effect of fulcrum between two first buffering refills 2, when guaranteeing shock-absorbing capacity, can guarantee the compressive strength of cardboard, avoids surface course 1 to deform the damage by a wide margin. The first buffer paper core 2 and the second buffer paper core 3 can be corrugated paper cores or honeycomb paper cores.

The thickness of the paper core and the surface layer 1 can be selected according to actual requirements.

Referring to fig. 2 and 3, in consideration of the lack of the strength of the whole paperboard in the horizontal direction, a reinforced paper core 6 is arranged in the middle of the adjacent paper cores, and the reinforced paper core 6 is in a local covering shape; the thickness of the reinforced paper core 6 is smaller than that of the paper core so as to leave a buffer space and a cavity for subsequent filling.

In the present application, the structures and the connection relations that are not described in detail are all the prior art, and the structures and the principles thereof are known in the prior art and are not described herein again.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
