Document Type and Number:
Japanese Patent JP4680413
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a stretchable film, composed of chlorine-free resin, having wrapping property of ordinary stretchable film, and usable for wrapping of low-temperature distribution foods. SOLUTION: The stretchable film excellent in low-temperature property is obtained by arranging tanδ of film to 0.2 or above, wherein tanδ is measured under frequency of 10 Hz and at -20 deg.C by dynamic viscoelasticity measurement. For example, this film is composed of a mixed composition with a specific ratio, of a linear low density polyethylene-based resin and a high-pressure processed polyethylene having different density to each other. This film has good wrapping property also at ambient temperature.
