MULTILAYER LAMINATE FOR LINER CONTAINING LIQUID MATERIALS

摘要

PURPOSE: A multi-layer laminate of a liner for containing liquid materials is provided to contain chemical solutions stably and to prevent damage due to external shock. CONSTITUTION: A multi-layer laminate comprises a first layer (110) of polyethylene or polycarbonate material, a second layer (120) of ceramic material, a third layer (130) of polyimide material, a fourth layer (140) of ceramic material and a fifth layer (150) of polyimide material. The ceramic is aluminum oxide or zirconium oxide. The thickness of the first layer is 130-200 μm. The thickness of the second layer and the fourth layer is 1-2 μm. The thickness of the third layer and the fifth layer is 20-50 μm. [Reference numerals] (AA) Outer surface; (BB) Inner surface
