摘要： The present invention provides: a resin pellet composition excellent in terms of low-classification property, kneadability with liquid ingredients, and transportability; a method for producing the resin pellet composition; and a method for producing a microporous polyolefin film from the resin pellet composition. The resin pellet composition comprises first pellets, which comprise a polyolefin, and 0.1-99.0 mass % liquid component. The first pellets are porous objects, some of which contain some of the liquid component infiltrated thereinto. In another embodiment, the resin pellet composition includes second pellets, which include a polyolefin. The second pellets are non-porous objects each comprising a portion made of a resin comprising the polyolefin and a portion made of a liquid component. The mass of the liquid component present on the outer surfaces of the second pellets is 20 mass % or less with respect to the total mass of the second pellets.

摘要： Provided is a microporous film which has a surface A and a surface B opposite to the surface A. In one embodiment, the microporous film has a ratio (FB/FA) of a dynamic friction coefficient FB of the surface B to a dynamic friction coefficient FA of the surface A of 1.2 to 20. In another embodiment, the microporous film is a single layer having a thickness of 3-18 μm, a number NA of pores on the surface A is 10-100/μm2, a number NB of pores on the surface B is 20-200/μm2, and NA/NB is 0.2-0.96. In addition, a total area SA of pores on the surface A is 0.02-0.5 μm2/μm2, a total area SB of pores on the surface B is 0.01-0.3 μm2/μm2, and SA/SB is 1.1-10. Furthermore, in another embodiment, a number WB of protrusion-like bodies on the surface B is 0.2-1000/100 μm2.
