摘要:
The invention generally relates to polymer film, and more particularly relates to polymeric membranes, methods for producing such membranes, and the use of such membranes as battery separator film. In an embodiment, the invention relates to liquid-permeable multi-layer microporous membranes comprising microlayers. According to the invention, liquid-permeable multi-layer microporous membranes having excellent physical properties including permeability can be produced without causing delaminate.

The invention relates to microporous membranes having one or more layers comprising polymer and inorganic molecules. The invention also relates to methods for producing these membranes, and the use of these membranes as battery separator film.
摘要:
A multi-layered sealable film and method of storing and transporting a role of the film without buckling or starring, the film comprising a core layer comprising polypropylene sandwiched between at least a first and (optionally) second tie-layer on either side of the core; a sealable layer with two sides, one side adhered to the first tie-layer; wherein at least the first tie-layer comprising a blend of polypropylene and within the range of from 5 wt % to 40 wt % of a soft polymer additive, preferably a propylene-α-olefin elastomer having within the range of from 10 wt % to 30 wt % α-olefin derived units, wherein the blend is preferably partially or completely immiscible. A roll of the inventive films can be readily stored and transported without loss due to film defects.
