摘要

The paper film composite comprises a first paper layer (10) and a second paper layer (30), and a composite film (20) that is concealed or laminated between the first and second paper layer and comprises two film layers, whose molecular orientation is inclined to each other. The molecular orientation is arranged in an angle of 45[deg] and aligned in a direction of the layer plain of the film layers. One of the first and second film layers consists of more than a paper layer. The paper type of the paper layers is different. The film layers are made of polyethylene.
