FILM FOR STRETCH PACKAGING
Document Type and Number:
Japanese Patent JP2022063198
Kind Code:
A
Abstract:
To provide a film for stretch packaging having a layer using a polypropylene resin as a major component, the film for stretch packaging excellent in a packaging aptitude (cutting properties, packaging wrinkle, bottom folding stability, tear strength), etc., hardly causing breakage in packaging, and having a transparent excellent appearance.SOLUTION: A film for stretch packaging includes at least one layer (I) containing, as a major component, a resin composition (Z) including: a polypropylene resin (A) having a glass-transition temperature of -15°C or lower, and a melting point of 130°C or lower, when raising a temperature again at 10°C/min. by differential scan calorimetry according to JIS K7121(2012), and an ethylene unit content of 6 mass% or more; and a polypropylene resin (B) having an ethylene unit content of less than 6 mass%. In the film, a loss tangent (tanδ) at 20°C measured with oscillation frequency of 10 Hz is 0.2 or more, and a storage elastic modulus (E') is 400 MPa or less.SELECTED DRAWING: None
