(57) [Abstract] [Purpose] To provide a polyethylene-2,6-naphthalate film which is excellent in flat slipperiness, abrasion resistance and mechanical strength. [Structure] Average particle size is 0.05 ~ 3μm, Spherical ratio is 1.0 And a polyethylene-2,6-naphthalate containing 0.01 to 3% by weight of crosslinked polymer particles containing an ethylene glycol unit. Deformation ratio of 1.2 due to stretching of crosslinked polymer particles Polyethylene, characterized in that 2,6-naphthalate film. |
