Description

A kind of packing board and packing box

technical field

The utility model relates to the field of packaging, in particular to a packaging board and a packaging box made of the packaging board.

Background technique

During the long-distance transportation of fruits and vegetables, the requirements for packing boxes are relatively high. They must not only keep warm and moisturize, but also meet the necessary strength. At present, there are two kinds of packaging methods commonly used in the market, one is carton packaging, and the other is foam box packaging. Carton packaging is generally made of corrugated paper, which has relatively high strength but relatively poor heat preservation and moisturizing effects. Moreover, cartons are afraid of water. During transportation, it is necessary to cover the outside with insulation materials and rainproof equipment. Foam box packaging is generally made of polystyrene or polyurethane material, which has good heat preservation and moisturizing effects, and is not afraid of water, but its strength is not high, and it is easy to be bumped during transportation.

Utility model content

The technical problem to be solved by the utility model is to provide a packaging board and a packaging box that have good heat preservation and moisturizing effects and high strength.

In order to solve the above problems, the utility model provides a packaging board, comprising: at least one heat insulation layer, at least one side of the heat insulation layer has a hard packaging material layer.

The heat insulation layer and the hard packaging material layer can be stacked or closely combined.

Further, there are hard packaging material layers on both sides of the heat insulation layer, or a hard packaging material layer on one side and a soft packaging material layer on the other side.

The heat insulation layer, the layer of soft packaging material and the layer of hard packaging material can be stacked or closely combined.

In the present invention, because it is mainly used for packaging food including fruits and vegetables, the material of the heat insulation layer is a foam material.

Further, the foam is polystyrene foam or polyurethane foam.

The rigid packaging material is cardboard or PVC board. The hard packaging material can ensure that the packaging board has relatively high strength and can bear the weight of foods including fruits.

Wherein, the cardboard is preferably corrugated cardboard.

Preferably, the corrugated paper layer is 3-5 layers.

The flexible packaging material is paper, film, woven cloth or non-woven cloth, wherein the paper can be specially selected kraft paper.

The thickness of the foam layer can be a conventional thickness, such as 0.3-8cm, and can also be selected according to the need for heat preservation.

The thickness of the paper layer can also adopt conventional thickness, such as 0.1-3cm, and can also be selected according to needs.

In particular, the packaging board of the present invention includes at least one heat insulation layer, and hard packaging material layers located on both sides of the heat insulation layer; wherein the heat insulation layer is a foam layer; the hard The packaging material layer is a corrugated cardboard layer.

If there are three layers, the foam layer is one layer; the corrugated cardboard layer is two layers; the foam layer is in the middle. Or the foam layer is 2 layers; the corrugated cardboard layer is 3 layers; the foam layer and the paper layer are arranged alternately.

The corrugated cardboard layer and the foam layer can be combined by conventional techniques such as heat pressing and bonding, and can also be stacked together.

The utility model also provides a packing box, the plate of the packing box is the packing plate of the present invention.

The outer side of the plate of the packing box is a hard packing material layer.

Preferably, the packaging board of the packing box includes at least one layer of heat insulation layer, and hard packaging material layers located on both sides of the heat insulation layer; wherein the heat insulation layer is a foam layer; the hard packaging The material layer is a corrugated cardboard layer.

If there are three layers, the foam layer is one layer; the corrugated cardboard layer is two layers; the foam layer is in the middle. Or the foam layer is 2 layers; the corrugated cardboard layer is 3 layers; the foam layer and the paper layer are arranged alternately.

Preferably, the foam layer is a polyphenylene layer or a polyurethane layer.

Preferably, the paper layer is a corrugated paper layer.

Preferably, the corrugated paper layer is 3-5 layers.

Technical effect of the present utility model:

The triple structure of paper layer-foam layer-paper layer is used to make packaging boards and boxes with good heat preservation and moisturizing effects and high strength, so as to realize heat preservation, fresh-keeping transportation and short-term storage of fresh products such as fruits and vegetables . The material used for the paper layer is 3-5 layers of corrugated paper, and the material used for the foam layer is polystyrene or polyurethane material, which can be reused and eventually recycled.
