摘要： Provided are a sheet manufacturing method and a processing device with which it is possible to impart greater stretchability to a base material sheet.
The sheet manufacturing method is provided with: a conveying step of conveying a base material sheet (2); and a processing step of rotationally driving a pair of processing rolls (12, 14) arranged to sandwich a conveyance path (3) on which the base material sheet (2) is conveyed, in a manner that irregular portions (13, 15) formed along respective outer peripheral faces (12s, 14s) of the processing rolls (12, 14) engage with each other with a clearance to stretch the base material sheet (2) when the base material sheet (2) passes between the processing rolls (12, 14). In the conveying step, the base material sheet (2) is conveyed in a manner that: the base material sheet (2) is in contact with and along the outer peripheral face (12s) of one of the processing rolls (12) immediately prior to passing between the processing rolls (12, 14); and the tension (T1) in the conveyance direction applied to the base material sheet (2) immediately prior to reaching the outer peripheral face (12s) of the one of the processing rolls (12) is less than 10% of a breaking load of the base material sheet (2) in the conveyance direction prior to processing.

摘要： The purpose of the present invention is to provide a polyolefin-based resin film that affords a laminate from which a packaging bag superior in transparency, bending pinhole resistance, and blocking resistance and capable of being easily torn without parting is obtained even when the polyolefin-based resin film is laminated on a base film having a large distortion of molecular orientation axis such as a biaxially stretched polyamide-based resin film. The polyolefin-based resin film includes a polyolefin-based resin composition, wherein the polyolefin-based resin composition includes at least a propylene-a olefin random copolymer and the following 1) to 5) are satisfied: 1) a content of an olefin-based block copolymer is 0 to 2 parts by weight based on 100 parts by weight of the propylene-a olefin random copolymer in the polyolefin-based resin composition; 2) a content of an olefin-based copolymeric elastomer resin is 0 to 2 parts by weight based on 100 parts by weight of the propylene-a olefin random copolymer in the polyolefin-based resin composition; 3) a content of a propylene homopolymer is 0 to 40 parts by weight based on 100 parts by weight of the propylene-a olefin random copolymer in the polyolefin-based resin composition; 4) the polyolefin-based resin film exhibits a thermal shrinkage rate after heating at 120°C for 30 minutes of 25% or less in a direction in which the thermal shrinkage rate after heating at 120°C for 30 minutes is larger between a longitudinal direction and a lateral direction of the polyolefin-based resin film; and 5) a planar orientation coefficient ΔP calculated from a refractive index of the polyolefin-based resin film is 0.0100 or more and 0.0145 or less.
