Document Type and Number:
Japanese Patent JP3296532
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a non-vinyl chloride resin stretched film good in wrapping workability and wrapped finish.
SOLUTION: This stretched film for wrapping foods has at least one of layers containing the below-described components (A) and (B), having a frequency of 10Hz by the measurement of dynamic viscoelasticity, a storage elastic modulus (E') of 5.0×108 to 5.0×109dyn/cm2 measured at a temperature of 20°C, and a loss tangent (tan δ) of 0.2-0.8. (A) One or more kinds of propylenic polymers having a crystallization calorie of 10J/g to 60J/g measured with a differential scanning calorimeter, when cooled down to 0°C at a scanning rate of 10°C/min, after the crystals are melted. (B) A petroleum resin, a terpene resin, a chromane-indene resin, a rosin resin, or their hydrogenation derivatives.
