Abstract
PURPOSE: To provide the titled film excellent in twisting property and adaptability to a twist wrapping machine by a method wherein a film of a polyester based resin containing an antistatic agent and a slipping agent is stretched in both longitudinal and transverse directions.
CONSTITUTION: A polyester based resin (for example, polyethylene terephthalate) having an intrinsic viscosity of not lower than 0.8, as measured at 25°C by using a 1/1 mixed solvent of phenol and tetrachloroethane, is added 2W3wt% of an antistatic agent[for example, N,N-bis(fatty acid) amide]and 0.2W0.4wt% of a slipping agent (for example, ethylenebisamide), and a film is formed from the mixture by an ordinary method. The film blank is stretched in both longitudinal and transverse directions at respective stretching ratios of 3.0W4.0. As an alternative, a film blank prepared from the polyester based resin is coated with 0.01W0.10g/m2 of the antistatic agent and 0.001W0.01g/m2 of the slipping agent, followed by longitudinal and transverse stretching at respective ratios of 3.0W4.0.
