Abstract
A high-performance multilayer films for packaging and the structure of the multilayer film is as follows: PO2/POY/PO1/POX/PO3 and PO2/POY/PO1/TIE2/PO3. The multilayer film is obtained by multilayer coextrusion and biaxial stretching. The total thickness of the multilayer film is 8 to 100 micrometers; the absolute values of the differences of the solubility parameters between the PO1 layer and the PO2 layer and between the PO2 layer and PO3 layer is greater than 0.5 (J·cm), and the absolute value of the difference of the cohesive energy density is greater than 5 J/cm.
