In the composite corrugated cardboard, the outer side surface of the outer cardboard layer is uniformly coated with the waterproof coating to form the outer waterproof layer, and the composite corrugated cardboard has the advantages of simple structure and convenience in processing.

In foretell compound corrugated paper boxboard, the inboard of foretell interior cardboard layer is equipped with interior waterproof layer, effectively restricts the inboard moisture of carton or liquid and flows toward boxboard inside, ensures boxboard overall structure stability, makes the stable realization of improvement anti-wearing property purpose.

In the composite corrugated paper boxboard, the thickness of the inner waterproof layer is 1 mm-3 mm.

In the composite corrugated cardboard box board, the inner side surface of the inner cardboard layer is uniformly coated with the waterproof coating to form the inner waterproof layer, and the composite corrugated cardboard box board has the advantages of simple structure and convenience in processing.

As another scheme, in the above composite corrugated cardboard, a sponge layer is bonded and fixed on the inner side surface of the inner cardboard layer, and the sponge layer is the above inner waterproof layer. The sponge layer realizes the waterproof effect by absorbing liquid and has the advantages of simple structure and convenient processing.

In the above composite corrugated cardboard, the waterproof film layer is a PE film layer.

Compared with the prior art, the composite corrugated cardboard box board has the following advantages:

1. set up the anti-wearing layer that is formed by nylon thin layer, waterproof film layer and kraft paper layer three complex between outer paperboard layer and corrugated core layer, because kraft paper and nylon film all possess good tensile strength and tensile strength, can obviously strengthen the anti penetration performance of boxboard, effectively prevent because the damaged article that leads to in the carton of boxboard and external contact pollution.

2. The waterproof thin film layer and the outer waterproof layer which are distributed inside and outside are arranged to form two waterproof barriers outside the kraft paper layer, so that the contact of the outside liquid of the carton and the kraft paper layer can be avoided, and the penetration resistance of the kraft paper layer can be fully exerted.

Fig. 2 is an enlarged schematic view of a structure at a in fig. 1.

In the figure, 1, a corrugated medium layer; 2. an inner paperboard layer; 3. an outer paper board layer; 4. a nylon film layer; 5. a waterproof film layer; 6. a kraft layer; 7. an outer waterproof layer; 8. and an inner waterproof layer.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example one

As shown in fig. 1 and 2, the composite corrugated cardboard sheet includes a corrugated medium layer 1, an inner cardboard layer 2 bonded to the inside of the corrugated medium layer 1, and an outer cardboard layer 3 provided to the outside of the corrugated medium layer 1.

In particular, the present invention relates to a method for producing,

as shown in fig. 2, a nylon film layer 4, a waterproof film layer 5 and a kraft paper layer 6 are sequentially arranged between the outer paperboard layer 3 and the corrugated core layer 1 from outside to inside, the nylon film layer 4 and the kraft paper layer 6 are respectively bonded on two sides of the waterproof film layer 5, and the outer paperboard layer 3 and the corrugated core layer 1 are respectively bonded on the nylon film layer 4 and the kraft paper layer 6. Set up the anti-wearing layer that is formed by nylon film layer 4, waterproof film layer 5 and kraft paper layer 6 three complex between outer paperboard layer 3 and corrugated core layer 1, because kraft paper and nylon film all possess good tensile strength and tensile strength, can obviously strengthen the anti penetration resistance of boxboard, effectively prevent because the damaged article that leads to in the carton of boxboard and external contact pollution.

Wherein, preferred nylon film layer 4 is the PE film layer, makes it possess certain tensile strength again when playing waterproof performance to further strengthen the anti penetration ability of the anti layer that wears that is formed by nylon film layer 4, waterproof film layer 5 and the compound of kraft paper layer 6 three.

For a further explanation,

an outer waterproof layer 7 is arranged on the outer side of the outer paperboard layer 3. The waterproof thin film layer 5 and the outer waterproof layer 7 which are distributed inside and outside are arranged to form two waterproof barriers outside the kraft layer 6, so that liquid outside the carton can be prevented from contacting the kraft layer 6, and the kraft layer 6 is ensured to fully exert the penetration resistance. Interior cardboard layer 2's inboard is equipped with interior waterproof layer 8, effectively restricts inboard moisture of carton or liquid toward the inside flow of boxboard, ensures boxboard overall structure stability, makes to improve the stable realization of anti-performance purpose of wearing.

In the present embodiment, it is preferred that,

the outer side surface of the outer paperboard layer 3 is evenly coated with waterproof paint to form the outer waterproof layer 7; the inner side of the inner cardboard layer 2 is uniformly coated with a waterproof coating to form the above-mentioned inner waterproof layer 8. Preferably, the thicknesses of the inner waterproof layer 8 and the outer waterproof layer 7 are 1 mm-3 mm, and in an actual product, the thickness of the inner waterproof layer 8 is 1.5mm; the thickness of the outer waterproof layer 7 is 2mm.
