Microlayer Films

摘要

Microlayer films are cast coextrusions with any-where from 30 to 1000 layers,each layer from 0.02 to 5 microns thick.Not some futuristic fantasy,these films are very real commercial products.The seemingly improblable feat of assembling all those layers is accomplished in a coextrusion feedblock by splitting and stacking a small number of input melt streams-sometimes no more than two or three.
