Patent

CA 2485265

A heat-shrinkable polyester film characterized in that: (A) the heat shrinkage percentages in the maximum shrinkage direction thereof is 10 to 50% in hot water at 70°C; (B) the heat shrinkage percentages in the maximum shrinkage direction thereof is 70% or more and that in the direction orthogonal to the maximum shrinkage direction is 10% or less in hot water at 85°C; and (C) when the heat shrinkage percentage in the maximum shrinkage direction in hot water at 95°C is designated as Xo (%) and the heat shrinkage percentage in the maximum shrinkage direction of a film obtained by previously heat-shrinking said film to an extent of 10% in hot water at 95°C is designated as X10 (%), the difference in heat shrinkage percentage .DELTA. (%) calculated according to the following equation is 10 to 20%. .DELTA. = X0 -X10

L'invention concerne un film polyester thermorétractable caractérisé en ce que (A) le degré de thermorétractation dans de l'eau à 70 DEG C est de 10 à 50 % comme mesuré dans la direction de rétractation maximale, (B) le degré de thermorétractation dans de l'eau à 85 DEG C est de 70 % minimum comme mesuré dans la direction de rétractation maximale et de 10 % maximum comme mesuré dans la direction perpendiculaire à la direction de rétractation maximale, et (C) la différence de thermorétractation LAMBDA (%) donnée par l'équation LAMBDA = X0 X10 est de 10 à 20 %, sous réserve que X0 (%) est le degré de thermorétractation dans de l'eau à 95 DEG C comme mesuré dans la direction de rétractation maximale et X10 (%) est le degré de thermorétractation d'un film thermorétracté à 10 % dans de l'eau à 95 DEG C comme mesuré dans la direction de rétractation principale.
