A brittle, biaxially oriented polypropylene film is provided by minimizing the nucleation density in the extruded and quenched polypropylene polymer cast sheet followed by maximizing the spherulitic growth rate of the resultant quenched polymer.

The plasticizer is present in an amount effective to prevent the film from becoming brittle.

The at least one plasticizer is present in an amount that is effective to prevent the film from becoming brittle.

Embodiments of a flight vehicle (20) including a scribed frangible seal (46) are provided, as are embodiments of a scribed frangible seal (46) and a method for equipping a flight vehicle (20) with a scribed frangible seal (46).

The frangible portion may include a frangible body.

The present invention relates to a polyamide film composition having excellent slipperiness and excellent workability because breakage thereof hardly occurs.

  While the brittle material (11) exists in a region where the brittle material is to be moved by a plurality of the rollers (13, 14), the pressurizing rollers (15, 15) are pressed down to the side of the brittle material (11).
