A substrate treating apparatus for successively treating substrates includes a body having a carrying unit for carrying the substrate along a carrying surface. The carrying surface is inclined in a plane perpendicular to the carrying direction of the substrate. The body supplies a treating liquid to the substrate being carried for treating the substrate. A receiving station is disposed upstream of the body for changing the posture of the substrate from a horizontal posture to an inclined posture corresponding to the inclination of the carrying surface, and for forwarding the substrate onto the carrying unit. In addition, a delivering station is disposed downstream of the body for returning the substrate forwarded from the carrying unit in the inclined posture to the horizontal posture.

Substrate treating apparatus and method for treating substrate

A metal-film laminate including a metal plate and a biaxially oriented polyester-group film laminated on the metal plate. The orientation degree of the film is controlled such that, when the thickness of the film is represented by T and the mean orientation degree of the film in the area from the metal-plate side surface to a position of T/2 in the thickness direction of the film is represented by X, the orientation degree of the film in the area from the metal-plate side surface to the position of T/2 is in the range of X.+-.0.5X and an orientation degree of the film at the non-metal-plate side surface is not less than 2X. When the metal-film laminate is processed by drawing etc., an excellent drawing property and an excellent impact resistance of an obtained metal-film laminated product can be achieved.

Metal-film laminate

Disclosed is a polyester film for use of a laminate with a metal plate comprising a polyester=group resin containing a white pigment having a mean particle diameter of 0.01 to 1.8 .mu.m at a content of 10 to 30% by weight. The film has (a) a void ratio of 4 to 30%, (b) a melting peak temperature of 150.degree. to 245.degree. C., (c) an amount of oligomer of not more than 3% by weight and (d) an orientation degree of 0.7 to 4.0. When the film is laminated on a metal, it can indicate excellent light interruptive property, lamination property, forming property and processing property.
