LAMINATED FILM AND CONTAINER |
摘要 |
PROBLEM TO BE SOLVED: To provide a laminated film having excellent flexibility without impairing characteristics such as high gas barrier properties or the like of a liquid crystalline polymer and exhibiting a sufficient heat sealing strength in the case of bag making and a container made by using the film. SOLUTION: The laminated film comprises a first layer made of a liquid crystalline polymer layer (A) exhibiting an optical anisotropy at a melting time and a second layer containing a heat sealing layer (B) in such a manner that the first layer and the second layer are laminated. In this case, a thickness of the first layer is 3 to less than 15μm, and the thickness of the second layer is 35 to less than 200μm. The film is used for the container.
