The utility model discloses at least, include following beneficial effect: the surface of the first core paper is plated with the food aluminum foil, so that the oil-proof function is realized; the wave structure of the first core paper forms a groove, so that the adhesion between the aluminum foil for food and the surface of oil-impregnated food after oil is soaked out is reduced; because the double-layer corrugated board is adhered to the three-layer corrugated board, the stiffness of the corrugated board is increased; the waterproof layer is adhered to the third surface paper of the three-layer corrugated board, so that the waterproof function is realized.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Drawings

Fig. 1 is a front view of the structure of an embodiment of the present invention.

In the figure: 1. a double-layer corrugated board; 2. a first core paper; 3. first surface paper; 4. aluminum foil for food; 5. three layers of corrugated boards; 6. second surface paper; 7. a second core paper; 8. and (7) third surface paper.

Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

Fig. 1 shows an implementation form according to the present invention, which includes: double-deck corrugated container board 1, double-deck corrugated container board 1 includes first face paper 3 and first core paper 2, first core paper 2 one side with first face paper 3 bonds mutually, and another side surface has plated food and has used aluminium foil 4, and oil stain food is held in above food uses aluminium foil 4. First core paper 2's shape is the wave, forms the recess between wave and the wave, aluminium foil 4 plates for food 2 surfaces on first core paper also form a plurality of recesses, hold oil stain food on the aluminium foil 4 for food leaches oil can flow down along the recess to reduce the adhesion between food aluminium foil 4 for food and oil stain food surface after the oil leaches, aluminium foil 4 for food is nontoxic tasteless, consequently can guarantee food safety, and aluminium foil 4 for food self has grease-proof beneficial effect simultaneously.

In the technical scheme, oil stains are placed on the food aluminum foil 4, and the food aluminum foil 4 can prevent the corrugated board from being polluted by the oil stains and protect the performance of the corrugated board; the food aluminum foil 4 maintains the same shape as the first core paper 2, and contacts with the oil-impregnated food only at the top of each corrugation, and the contact area is very limited; after being leached, the oil flows downwards along the surface of the aluminum foil 4 under the action of gravity, flows into a groove formed at the bottom of the corrugation wrapped by the aluminum foil 4 for food, and cannot stay at the top of the corrugation wrapped by the aluminum foil 4 for food; thereby reducing the adhesion between the oil-stained food and the food-grade aluminum foil 4.

One implementation of the corrugated board for packaging oil-impregnated food in the scheme is as follows: the corrugated height of the double-layer corrugated board 1 is 4-6 mm. By adopting the scheme, the corrugated board with the corrugation height of 4-6 mm has the advantages of high compressive strength, high elasticity and good buffering performance.

One implementation of the corrugated board for packaging oil-impregnated food in the scheme is as follows: the thickness of the food aluminum foil 4 is 0.005-0.02 mm. In this embodiment, it is more difficult to plate the food grade aluminum foil 4 having a thickness of more than 0.02 mm on the surface of the first core paper 2, and the food grade aluminum foil 4 having a thickness of less than 0.005 mm is too thin and has insufficient oil-proof capability, so that the food grade aluminum foil 4 having a thickness of 0.005-0.02 mm is the most suitable embodiment.

One implementation of the corrugated board for packaging oil-impregnated food in the scheme is as follows: the other side of the first face paper 3 bonded with the first core paper 2 is also bonded with a three-layer corrugated board 5, the three-layer corrugated board 5 comprises a second face paper 6, a second core paper 7 and a third face paper 8, the second core paper 7 is bonded between the second face paper 6 and the third face paper 8, and the other side of the second face paper 6 is bonded with the first face paper 3. By adopting the scheme, the double-layer corrugated board 1 only comprises the first core paper 2 and the first face paper 3, has no stiffness and is not suitable for transportation, so the first face paper 3 of the double-layer corrugated board 1 is bonded on the second face paper 6 of the three-layer corrugated board 5, the whole corrugated board has stiffness, the pressure resistance of the corrugated board is improved, and food is protected in the transportation process.

One implementation of the corrugated board for packaging oil-impregnated food in the scheme is as follows: the three-layer corrugated board 5 is an E-shaped corrugated board. Compared with other types of corrugated boards, the E-shaped corrugated board has good bidirectional rigidity, can reduce surface bending and external force impact, and increases the cushioning property of the corrugated board.

One implementation of the corrugated board for packaging oil-impregnated food in the scheme is as follows: and a waterproof layer is also adhered on the third surface paper 8 of the three-layer corrugated board 5. In the scheme, the compressive strength and hardness of the common corrugated board can be reduced when meeting water, even the common corrugated board can become waste paper if the common corrugated board is serious, and the waterproof layer is bonded on the surface of the three-layer corrugated board 5 to prevent the invasion of moisture, protect the corrugated board and enable the corrugated board to be more durable.

One implementation of the corrugated board for packaging oil-impregnated food in the scheme is as follows: the waterproof layer is made of thermoplastic polyurethane material. Compared with other waterproof materials, the thermoplastic polyurethane material has the characteristics of wear resistance, oil resistance and mildew resistance, and is long in service life, and the scheme is more practical.

As described above, according to the present invention, since the food aluminum foil 4 is plated on the surface of the first core paper 2, the oil-proof function is achieved; the wave structure of the first core paper 2 forms a groove, so that the adhesion between the food aluminum foil 4 and the surface of the oil-impregnated food after the oil is leached is reduced; the double-layer corrugated board 1 is adhered to the three-layer corrugated board 5, so that the stiffness of the corrugated board is increased; the waterproof layer is adhered on the third surface paper 8 of the three-layer corrugated board 5, so that the waterproof function is realized.

While embodiments of the invention have been disclosed above, it is not intended to be limited to the applications listed in the specification and the examples. It can be applicable to various and be fit for the utility model discloses a field completely. Additional modifications will readily occur to those skilled in the art. The invention is therefore not to be limited to the specific details and illustrations shown and described herein, without departing from the general concept defined by the claims and their equivalents.
