PURPOSE:To develop a twist-wrapping film generating no pitch shift at the time of multicolor printing and suitable for twist-wrapping of high modulus of elasticity using a film having physical properties stable against a humidity change, high twist retentivity and high display effect and excellent in transparency and glossiness. CONSTITUTION:A twist-wrapping film is formed by biaxially stretching a preparatory molded body for stretching composed of a styrenic polymer having a syndiotactic structure or a composition thereof. As a result, the twist-wrapping film suitable for twist-wrapping having excellent transparency and glossiness and high display effect, extremely improved in twist retentivity, mechanical characteristics and dimensional stability against humidity, almost generating no rupture, hardly generating pitch shift at the time of printing because of high modulus of elasticity and susceptible to multicolor printing is obtained. |
