ABSTRACT:
An easy-cleavage film comprising a first layer, a second layer and a third layer which contain Nylon 6 (Ny 6), meta-xylylene adipamide (MXD 6) and polyamide elastomer (PAE), in which the film is defined by (1) the content of the components of each layer, (2) the layer ratio of each layer and (3) the orientation ratio, more specifically, (1) the first layer and the third layer having 60 to 85% by weight of Ny 6 content, 15 to 40% by weight of MXD 6 content and 0.1 to 10.0% by weight of PAE content, the second layer having 0 to 40% by weight of Ny 6 content, 60 to 100% by weight of MXD 6 content and 0.1 to 10.0% by weight of PAE content (each layer having Ny 6+MXD 6+PAE=100% by weight, further, the MXD 6 content in the second layer being larger than the MXD 6 content in the first layer and the third layer), (2) the layer ratio of the first layer through the third layer being defined as 1:8:1-4:2:4, the layer ratio between the first layer (or the third layer) and the second layer being defined as 1:8-2:1, and the layer ratio between the first layer and the third layer being defined as 1:2-2:1, and (3) an orientation ratio of more than 2.8 times in both the direction of the movement of the film (MD direction) and the direction of the width of the film (TD direction).
