Document Type and Number:
Japanese Patent JP7355591
Kind Code:
B2
Abstract:
To provide a stretched film that has low-temperature heat shrinkability, offering excellent thermal shrinkage, and has low natural shrinkage and high tensile elasticity.SOLUTION: A stretched film comprises a polymer composition comprising: 40-90 mass% of a propylene polymer (A) having a melting point (Tm) of at 150-180°C as measured by differential scanning calorimetry (DSC); and 10-60 mass% of a propylene copolymer (B) having a melting point (Tm) of less than 120°C as measured by differential scanning calorimetry (DSC) or having no melting point (Tm) observed [where, the total of (A) and (B) is 100 mass%], the stretched film having a tensile elasticity of 1.5 GPa or more in vertical direction (MD).SELECTED DRAWING: None
