摘要: A coextrusion apparatus for producing a multilayer film or sheet of diverse thermoplastic materials has slit die and feedblock assembly integrated into the die. The includes removable received within cavity plurality slotted, layer distribution passages opening coathanger-type expansion chamber via shallow entrance section. are mutually spaced apart lie parallel to slotted outlet
