Management of countermeasure of pollution particles deposited on an object to be processed is optimized based on a cause of the pollution. Data processing and management equipmentcomprises a functional approximation partto make a mathematical model of a relation between measured numbers of particles deposited on a substrate during processing in a surface structuring device or a film forming device and accumulated amount processed after cleaning up of the device by a functional equation based on a cause of the deposit of the particles. A judging partspecifies the cause of the deposit of particles by comparing the functional equation with the measured numbers of particles.

Data processing and management equipment and method for data analysis of particles in surface structuring device or film forming device

A process for producing a porous film or sheet, which comprises melt-molding a composition prepared by compounding 100 parts by weight of a polyolefin resin with 25 to 400 parts by weight of a filler and 1 to 100 parts by weight of a liquid or waxy hydrocarbon polymer into film or sheet, and stretching the resulting film or sheet.

Process for producing porous film or sheet

A polyolefin resin composition obtained by mixing a polyolefin resin with minor proportion of a polybutene of low molecular weight, a mixed glyceride containing a lower acyl group and a higher acyl group, and preferably a surface wetting agent, is used to form a polyolefin film, which is thereafter aged. The thus formed film exhibits very excellent adhesion strength as well as very good transparency and physical strength, and is therefore suitable for use as a food packaging film.

Polyolefin resin composition and method for making polyolefin film

A tacky polyolefin film is prepared by forming a film using a composition comprising a polyolefin resin, a low grade polyolefin and a tackifier and aging the resulting film.
