Description

High-plasticity paperboard replacing wood with paper

Technical Field

The utility model relates to the field of packaging technology, the concrete field is a replace wooden high plasticity cardboard with paper.

Background

The packing box commonly used in the packaging industry at present has a paper box and a wood box, and the cost of the paper box is far lower than that of the wood box, so the using amount is large. The paper boxes are corrugated paper boxes, single-layer paper boxes and the like according to different materials, and the corrugated paper boxes have various specifications and models.

When products are packaged and transported, a foam box or a corrugated case is usually adopted, so that the recovery cost of the foam box is high, and white pollution is easily caused; although the corrugated case is easy to recycle, the corrugated case does not have the characteristics of water resistance and moisture resistance, and when the corrugated case is used for handling articles with higher weight, the corrugated case is easy to damage during transportation and brings certain inconvenience to the transportation due to the limitation of materials per se, low strength and easy tearing.

To sum up, how to provide a carton, when the environmental protection, improve the dampproofing effect of resistance to compression of carton, make the carton be convenient for transport, the problem that present field technical personnel need to solve urgently.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide an with paper high plasticity cardboard of replacing wood, it can realize improving the intensity and the humidity resistance of cardboard.

In order to achieve the above object, the utility model provides a following technical scheme: a high-plasticity paper board replacing wood with paper comprises a corrugated paper board, a supporting roll and two panels; the panel and the support roll both comprise a kraft layer and a non-woven fabric layer; the kraft paper layer is bonded with the non-woven fabric layer;

Detailed Description

The following detailed description of the embodiments of the invention, taken in conjunction with the accompanying drawings, will make it clear to those skilled in the art how the invention may be practiced. While the invention has been described in connection with its preferred embodiments, these embodiments are intended to be illustrative, and not to limit the scope of the invention.

The first embodiment is as follows: referring to fig. 1-3, a paper-based high plastic paperboard includes a corrugated board 1, a support roll 2 and a panel 3.

As shown in fig. 2, the corrugated cardboard 1 is formed by bonding an upper kraft paper and a lower kraft paper and a corrugated heavy corrugated paper 101 located between the two kraft papers; in the present embodiment, the heavy corrugated paper 102 is made of pulp with a high grammage; the thickness of the corrugated board 1 is 5mm to 6mm, and the adoption of the arrangement can ensure that the corrugated board 1 has high compressive strength and is rich in elasticity and cushioning.

As shown in fig. 3, the support roll 2 has a spiral structure, and the support roll 2 is formed by bonding a layer of kraft paper and a layer of non-woven fabric 201; specifically, the outer layer of the support roll 2 is non-woven fabric, and the inner layer is kraft paper; the non-woven fabric is made of PP materials, has the characteristics of moisture resistance, air permeability, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity, no irritation, rich colors, low price, recycling and the like, can enable the support roll 2 to obtain the properties of moisture resistance, flexibility and the like by virtue of the characteristics of the non-woven fabric, and enables the spiral structure of the support roll 2 to have elasticity and not to be deformed easily; both the non-woven fabric and the kraft paper have the characteristic of easy decomposition, so that the support roll 2 formed by bonding the non-woven fabric and the kraft paper also has the characteristic of easy decomposition; in this embodiment, the panel 3 is also made of a layer of kraft paper and a layer of non-woven fabric bonded together.

As shown in fig. 1, the paperboard comprises a sandwich part and two panels 3, the number of the panels 3 is two, the two panels 3 are arranged oppositely, one surface of kraft paper is positioned at the inner side, and one surface of non-woven fabric is positioned at the outer side, and the arrangement is to achieve better moisture-proof effect; the interlayer part consists of a plurality of corrugated boards 1 and a plurality of supporting rolls 2, the corrugated boards 1 and the supporting rolls 2 are arranged at intervals, wherein the width of the corrugated boards 1 is equal to the inner diameter of the supporting rolls 2 and the width of the corrugated boards 1 is equal to the distance between two panels 3; the supporting roll 2 is in line contact with the corrugated board 1 and the panel 3; the corrugated board 1 not only plays a role of supporting the panel 3 but also improves the compressive strength of the corrugated board through the rigidity of the corrugated board; the support is rolled up 2 and is improved the anti buffer capacity of cardboard through the pliability of self, supports simultaneously and rolls up 2 inside spaces and make the cardboard lighter, reduces the cost of transportation that the cardboard brought for the packing.

Through this technical scheme, through set up by corrugated container board 1 and support the intermediate layer that 2 intervals of book set up and constitute in the cardboard for the cardboard has compressive capacity and anti-cushioning ability concurrently, and simultaneously, the panel is formed by kraft paper and non-woven fabrics bonding, has increased dampproofing ability for the cardboard through non-woven fabrics self humidity resistance.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
