<p>There is provided a novel chlorine-free stretch packaging film which has good packaging workability, packaging finish, elastic recovery, bottom sealing stability and transparency, hardly suffers from occurrence of tearing thereof and breakage when used in a low temperature condition, and is excellent in storage stability as pellets and economy. The stretch packaging film of the present invention comprises a layer X comprising a resin composition X which comprises, as main components, a propylene-ethylene random copolymer (A) which has an ethylene content of not less than 5% by mass and satisfies the condition that a single peak is observed in a crystallization curve of the component (A), and the peak temperature is not higher than 70°C (condition (1)), and a crystalline polypropylene-based resin (B) which satisfies the condition that among peaks observed in a crystallization curve of the component (B), the maximum peak temperature is higher than 70°C (condition (2)), wherein a mass ratio of the component (A) to the component (B) ((A) : (B)) is 8:2 to 2:8.</p> |
