Title:
POLYOLEFIN-BASED FILM, LAMINATE, PACKAGING MATERIAL, AND PACKAGING
Document Type and Number:
Japanese Patent JP2023164765
Kind Code:
A
Abstract:
To provide a polyolefin-based film excellent in structural stability to heat during vapor deposition, and excellent also in moisture barrier property, oxygen barrier property even to heat during heat sterilization, when using in, for example, packaging.SOLUTION: When the storage modulus in a direction of a main orientation axis at 50°C and 121°C obtained at a dynamic viscoelasticity measurement frequency of 10 Hz is E'50 (Pa) and E'121 (Pa), respectively, E'121/E'50 is more than 0.25 and 0.99 or less, a heat shrinkage rate in a main orientation axis direction at 150°C is -2% or more and 10% or less, and the tensile elongation in a direction perpendicular to the main orientation axis is 20% or more and 300% or less, and has at least one layer (layer A) containing a cyclic olefin resin and a polypropylene resin.SELECTED DRAWING: Figure 1
