Title:
ALUMINIUM-PLASTIC COMPOSITE FILM WITH HIGH WATER-BLOCKING PERFORMANCE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/032698
Kind Code:
A1
Abstract:
In the present invention, after PP is modified, the modified PP is added to reduce water and oxygen permeability so that permeability drops to 10-15% of the original, greatly improving performance; the gaps of unmodified PP are straight paths, and can be quickly passed; now, by means of the gaps of the modified PP being curved paths, the time taken for water and oxygen to pass through the curved paths is 10-100 times longer than the time taken to pass the original straight paths; an aluminium-plastic composite film with high water-blocking performance and a preparation method therefor: an inner layer of the aluminium-plastic composite film comprises an adhesive MPP layer, a PP layer, and a heat-sealing PP layer stacked in sequence, at least one of the adhesive MPP layer, the PP layer, and the heat-sealing PP layer being modified by adding a water-blocking nanomaterial.
