Abstract
(EN)
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).

L'invention concerne un film pour le revêtement d'une plaque métallique, caractérisé en ce que : le rapport du Module de Young EMD dans la direction machine au module de Young ETD dans la direction transversale, à savoir (EMD/ETD), se situe dans la plage de 1,1 à 4,0 (valeurs extrêmes incluses) ; et le retrait thermique à 200°C tel que mesuré par un analyseur thermomécanique est inférieur ou égal à 20 %, à la fois dans la direction machine et dans la direction transversale. Il est préférable que la somme du module de Young EMD dans la direction machine et du module de Young ETD dans la direction transversale, à savoir (EMD + ETD), se situe dans la plage de 3000 MPa à 12 000 MPa (valeurs extrêmes incluses). Il est également préférable que la température du pic de fusion le plus bas Tm1 soit située dans la plage allant de 210°C à 280°C (valeurs extrêmes incluses).
