The present invention relates to an antistatic sheet including a multilayer structure including a base (X), a layer (Z) containing an aluminum atom, and a layer (Y). The layer (Y) contains a polymer (A) having a vinylphosphonic acid unit, and the layer (Y) has a surface electrical resistivity of 1.0×10.sup.6 Ω/sq or more and 4.0×10.sup.13 Ω/sq or less.

A composite film includes a polyester film substrate layer and a crosslinked layer on a surface thereof, wherein the crosslinked layer includes a reaction product of a) a functionalized ethylene vinyl acetate copolymer including multiple COOH groups or multiple alcoholic OH groups per molecule; and b) an organic crosslinker including multiple reactive groups per molecule, the reactive groups being reactive with the COOH or alcoholic OH groups; wherein the adhesion strength between the substrate layer and the crosslinked layer is at least 177 g/cm (450 g/inch). A method of joining the composite film, optionally further including a heat-sealable polymer layer on the crosslinked layer, to a container or a self-supporting film, includes contacting the crosslinked layer or the heat-sealable polymer layer with the container or the self-supporting film or under heat sealing conditions.

The invention discloses bi-axially oriented coated polyester films having high tear initiation resistance and comprising a polyester base film and a heat sealable coating, said heat sealable coating comprising one or more amorphous copolyester(s) comprising units of terephthalic acid, naphthalene dicarboxylic acid and at least one diol. The films are heat-sealable and peelable to polyester and aluminium containers. The invention also relates to a process for the manufacturing of such films, to the use of said films in food packaging and to the packages obtained therefrom.
