Embodiment Construction
[0018] The present invention will be further described below in conjunction with the drawings.
[0019] Such as figure 1 As shown, a permanent antistatic high-barrier functional film includes an EVOH high-barrier layer. The upper and lower surfaces of the EVOH high-barrier layer are respectively provided with a PA anti-piercing layer. The PA anti-piercing layer has a high barrier to EVOH. One side of the layer is provided with an anti-release layer, and the side of the anti-release layer opposite to the PA puncture-resistant layer is provided with a permanent antistatic layer.
[0020] The permanent antistatic high-barrier functional film of the present invention, in which the EVOH high-barrier layer can make the film achieve the most obvious barrier effect, and the PA anti-piercing layer can improve the piercing resistance of the film and enhance the barrier effect, preventing release The layer is used to firmly connect the PA anti-piercing layer and the permanent antistatic laye...
