1. a method for preparing the extrahigh-molecular weight polyolefins film comprises the steps:

  • The initial extrahigh-molecular weight polyolefins that the isobaric press of-use makes weight average molecular weight be at least the powder type of 500000g/mol stands compression step,-arbitrarily a bit its temperature in polymer processing does not all rise under the condition above the value of its fusing point, makes the polyolefin of compression stand rolling step and at least one stretching step.
