Title:
剥離フィルムロール、セラミック部品シート及びその製造方法、並びに、セラミック部品及びその製造方法
Document Type and Number:
Japanese Patent JP7447988
Kind Code:
B2
Abstract:
This release film roll comprises: a release film that has a base material film and a release layer; and a winding core on which the release film is wound. When a distance r [mm] from the outer peripheral surface of the winding core along the radial direction on the side surface of the release film roll is 10-130 mm, the rebound hardness K(r) [HL] of the surface of the release film exposed on the outer peripheral surface of the roll as measured in the direction towards the center of the winding core satisfies formula (1). Formula (1): -2r+670≤K(r)≤-1.25r+862.5
