Fig. 1 is a schematic view of a paperboard mechanism according to an embodiment of the utility model.

Detailed Description

The preferred embodiments of the present utility model will be described in detail below with reference to the attached drawings, which further illustrate the present utility model.

First, a cardboard mechanism according to an embodiment of the present utility model will be described with reference to fig. 1 for composing a carton, which has a wide application.

As shown in fig. 1, the paperboard mechanism of the embodiment of the utility model has a base plate and an anti-collision layer 2.

Specifically, as shown in fig. 1, the anti-collision layer 2 is arranged at the top of the substrate, and the anti-collision layer 2 is made of EVA (ethylene-vinyl acetate) material and used for anti-collision protection, so that the service life of the anti-collision layer 2 can be prolonged, and other anti-collision materials with certain buffering can be adopted. The thickness of the anti-collision layer 2 is 5mm, and the thickness can be adjusted according to the requirement.

Further, as shown in fig. 1, in the present embodiment, the substrate is composed of a face paper layer 11, a first corrugated layer 12, a middle paper layer 13, a second corrugated layer 14, and a back paper layer 15, which are disposed in this order from the top to the bottom, and the top of the face paper layer 11 is connected to the impact layer 2. Vibration can be absorbed through the first corrugated layer 12 and the second corrugated layer 14, and the damping effect is achieved.

Further, in the present embodiment, the surface paper layer 11 is a recycled paper layer, and has a certain environmental protection property.

Further, in the present embodiment, the first corrugated layer 12, the middle paper layer 13, and the second corrugated layer 14 are all high-watt papers.

Further, the inner paper layer 15 is kraft paper.

Further, the grammage of the face ply 11 is 200g/m2, the grammage of the first corrugated ply 12 is 100g/m2, the grammage of the middle ply 13 is 100g/m2, the grammage of the second corrugated ply 14 is 140g/m2, and the grammage of the liner is 200g/m2. Depending on the field of application of the cardboard structure, the different g numbers required can be chosen. In particular, the desired stiffness value of the paperboard structure may also be adjusted by the construction of the base plate.

Further, the cross sections of the first corrugated layer 12 and the second corrugated layer 14 are all V-shaped corrugations, the opening angles of the V-shaped corrugations of the cross sections of the first corrugated layer 12 and the second corrugated layer 14 are the same, and the buffer performance is good.

In the above, the paperboard structure according to the embodiment of the utility model is described with reference to fig. 1, and the drop impact resistance of the carton formed by the paperboard structure is enhanced by providing an anti-collision layer 2 of EVA on the outside of the substrate, and is environmentally friendly and durable.

According to another embodiment of the utility model, a carton is provided comprising the paperboard structure of one embodiment, having good drop impact resistance and being environmentally friendly and durable.
