FILM FOR COATING METAL PLATE AND RESIN-COATED METAL PLATE

Title:

FILM FOR COATING METAL PLATE AND RESIN-COATED METAL PLATE

Document Type and Number:

WIPO Patent Application WO/2020/090552

Kind Code:

A1

Abstract:

This film for coating a metal plate is characterized in that: the ratio of the Young's modulus EMD in the machine direction to the the Young's modulus ETD in the transverse direction, namely (EMD/ETD) is within the range of from 1.1 to 4.0 (inclusive); and the thermal shrinkage at 200°C as measured by a thermomechanical analyzer is 20% or less in both the machine direction and the transverse direction. It is preferable that the sum of the Young's modulus EMD in the machine direction and the the Young's modulus ETD in the transverse direction, namely (EMD + ETD) is within the range of from 3,000 MPa to 12,000 MPa (inclusive). It is also preferable that the lowest melting peak temperature Tm1 is within the range of from 210°C to 280°C (inclusive).
