Abstract

The utility model discloses a letter-envelope paper structure and a letter paper bag, which comprise a kraft paper layer, a honeycomb paper layer and a corrugated paperboard layer, wherein the kraft paper layer, the honeycomb paper layer and the corrugated paperboard layer are sequentially bonded together from top to bottom. Because the honeycomb paper layer and the corrugated paperboard layer are sequentially arranged on the inner side of the kraft paper layer, the design can greatly improve the buffering effect and the puncture resistance effect of the envelope paper through the composite structure of the honeycomb paper layer and the corrugated paperboard layer, and meanwhile, the composite structure of the honeycomb paper layer and the corrugated paperboard layer is used for replacing the PE bubble layer lining of the envelope paper bag in the prior art, and plastics are not used, so the envelope paper is environment-friendly and pollution-free.

Description

Envelope paper structure and envelope paper bag

Technical Field

The utility model relates to the technical field of packaging paper bags, in particular to a letter envelope paper structure and a letter envelope paper bag.

Background

In the envelope bag used at present, the outer layer of the envelope bag is usually kraft paper, aluminum foil or aluminizer, and the lining is provided with a bubble buffer layer, the envelope bag has a certain buffer protection effect on products, but the inner layer is a PE bubble layer, so that the envelope bag is harmful to the environment and is not environment-friendly.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides an envelope paper structure, which mainly solves the technical problem that the existing envelope paper bag using kraft paper to line a PE bubble buffer layer is harmful to the environment and is not environment-friendly.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

the envelope paper structure comprises a kraft layer, a honeycomb paper layer and a corrugated board layer, wherein the kraft layer, the honeycomb paper layer and the corrugated board layer are sequentially bonded together from top to bottom.

Further, the corrugated board layer is a composite board structure formed by bonding a corrugated structure and kraft paper.

Further, the honeycomb paper layer is of a grid-shaped honeycomb paper structure.

Further, a kraft paper layer is bonded on one side of the honeycomb paper layer, and the other side of the honeycomb paper layer is bonded with one side of the corrugated structure of the corrugated cardboard layer.

Based on the same inventive concept, the utility model also provides an envelope paper bag which is made of any one of the envelope paper structures.

Further, the kraft paper layer is configured as an outer surface layer of the envelope paper bag, and the corrugated cardboard layer is configured as an inner surface layer of the envelope paper bag.

Further, the kraft paper layer is configured as an inner surface layer of the envelope paper bag, and the corrugated cardboard layer is configured as an outer surface layer of the envelope paper bag.

The technical scheme has the following advantages or beneficial effects:

according to the envelope paper structure and the envelope paper bag, the honeycomb paper layer and the corrugated paperboard layer are sequentially arranged on the inner side of the kraft paper layer, so that the design can greatly improve the buffering effect and the puncture resistance effect of the envelope paper through the composite structure of the honeycomb paper layer and the corrugated paperboard layer, and meanwhile, the composite structure of the honeycomb paper layer and the corrugated paperboard layer is used for replacing the PE bubble layer lining of the envelope paper bag in the prior art, plastics are not used, and therefore, the envelope paper structure and the envelope paper bag are environment-friendly and pollution-free.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Description of the reference symbols:

1. kraft paper layer, 2, honeycomb paper layer, 3, corrugated board layer.

Detailed Description

The utility model is further described with reference to the following figures and examples.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1, an embodiment of the present invention provides an envelope paper structure, which includes a kraft paper layer 1, a honeycomb paper layer 2, and a corrugated cardboard layer 3, wherein the kraft paper layer 1, the honeycomb paper layer 2, and the corrugated cardboard layer 3 are sequentially bonded together in an up-down manner. It can be understood that, in this embodiment, honeycomb paper layer 2 and corrugated board layer 3 have set gradually in the inboard of kraft paper layer 1, so design, through the composite construction of honeycomb paper layer 2 and corrugated board layer 3, both can improve envelope paper's buffering effect and resistant puncture effect greatly, simultaneously, use the PE bubble layer inside lining of envelope container bag among the composite construction replacement prior art through honeycomb paper layer 2 and corrugated board layer 3, do not use plastics anymore, consequently to environmental protection nuisanceless.

Referring to fig. 1, in a preferred embodiment, the corrugated cardboard layer 3 is a composite cardboard structure formed by bonding a corrugated structure and kraft paper.

Referring to fig. 1, in a preferred embodiment, the honeycomb paper layer 2 is a grid honeycomb paper structure.

Referring to fig. 1, in a preferred embodiment, a kraft paper layer 1 is bonded to one side of a honeycomb paper layer 2, and the other side of the honeycomb paper layer 2 is bonded to one side of the corrugated structure of a corrugated cardboard layer 3.

Referring to fig. 1, an embodiment of the present invention further provides a paper envelope bag, which is made by cutting and stretching the structure of the envelope paper according to any of the above embodiments. Referring to fig. 1 of the drawings, in a preferred embodiment, a kraft paper layer 1 is provided as an outer surface layer of a paper envelope bag and a corrugated cardboard layer 3 is provided as an inner surface layer of the paper envelope bag. However, it will be appreciated by those skilled in the art that in other embodiments the kraft paper layer 1 may also be configured as an inner skin of a paper envelope bag and correspondingly the corrugated board layer 3 is configured as an outer skin of a paper envelope bag. It can be understood that, because the envelope container bag of this embodiment is made by the compound three-layer composite construction who forms of kraft paper layer, honeycomb paper layer 2 and corrugated board layer 3, consequently, can provide good buffering effect through honeycomb paper layer 2 and corrugated board layer 3's combined action, greatly reduced in the envelope container article receive the impact and fall produced damage risk, simultaneously, because corrugated board layer 3's existence, can improve the puncture-resistant effect of envelope container bag to a great extent, in order to improve the transportation security of article.
