Specific embodiment
Below with reference to specific embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are simultaneously
The present invention is not limited, structure that those skilled in the art are made according to these embodiments, method or functionally
Transformation is included within the scope of protection of the present invention.
Referring to Figure 1 to 3, a kind of environmental protection carton material, including wood pulp paper layer 1 is densely covered on the wood pulp paper layer 1 several
Aperture 3；
It further include stone paper layer 2, the stone paper layer 2 is two layers and is attached respectively to 1 two sides of wood pulp paper layer, two layers
Stone paper layer 2 is integrated by 3 welding of aperture on the wood pulp paper layer 1.
It should be noted that the setting of wood pulp paper layer 1 of hard can make the environmental protection carton material have preferably in centre
Stiffness, and the dosage of wood pulp paper can be reduced by adhering to setting 2 one side of stone paper layer in two sides, on the other hand can make the ring
