Title:
WRAP FILM AND BODY WOUND WITH WRAPPED FILM
Document Type and Number:
WIPO Patent Application WO/2019/049750
Kind Code:
A1
Abstract:
Provided is a wrap film that has excellent adhesion during use, has tension and stiffness, is transparent, exhibits an effect for preventing vertical splitting and an effect for preventing re-winding, does not readily split even after being heated at high temperatures (e.g., over an electric range), has a low frequency of splitting during rewinding, and has exceptional oxygen/water barrier properties. This wrap film has a tensile strength of 100 MPa or higher, a tensile elasticity of 100% or lower, and a tensile modulus of 280 MPa or higher in the direction (TD) perpendicular to the flow direction, and has a tensile modulus of 380 MPa or higher in the flow direction (MD), the crystal long period preferably being 12.5 nm or less.
