Document Type and Number:

WIPO Patent Application WO/2014/073512

Kind Code:

A1

Abstract:

Provided is a novel, non-chlorine-based stretch wrapping film having favorable wrapping aptness such as favorable wrapping efficiency and a beautiful wrapping finish even if wrapping is performed by an automatic wrapping machine adapted for polyvinyl chloride. The laminate film is configured from at least three layers, and has two outermost layers containing an ethylene-based resin (A) component as the primary component and a middle layer containing a propylene-based resin (B) component as the primary component. According to a dynamic viscoelasticity measurement method, the average value of the tangent loss (tanδ) at -40 to 0°C measured at a vibration frequency of 10 Hz and a strain of 0.1% is at least 0.12, and the tangent loss (tanδ) at 20° is at least 0.20.
