    • The invention relates to a process for preparing a sequentially stretched biaxially oriented film, comprising the following steps: a) Melting a composition comprising at least 50 wt % with respect to the total amount of the composition of a copolyamide comprising: i. At least 75 wt% monomeric units derived from caprolactam, and further monomeric units derived from diamines X and/or diacids Y and/or aminoacids Z in a summed amount of between 0.2 to 25 wt%; or ii. At least 75 wt% monomeric units derived from hexamethylene diamine and adipic acid, and further monomeric units derived from diamines X and/or diacids Y and/or aminoacids Z in a summed amount of between 0.2 to 25 wt%; into a polymer melt; b) Casting the polymer melt through a planar die to form a film of at least one layer and subsequently quenching the film to a temperature of below Tg of the copolyamide, while the film is transported in a direction, referred to as machine direction; c) Stretching the film obtained after quenching in a direction parallel to the machine direction (MD-stretching) with a draw ratio DR MD at a temperature of at least Tg of the copolyamide; d) Stretching the film obtained after MD stretching in a direction transversal to the machine direction (TD-stretching) with a draw ratio DR TD at a temperature of at least Tg+ 10°C of the copolyamide; e) Heat setting the film obtained after cooling and stretching, at a temperature of between Tm-70°C and Tm of the copolyamide; in which Tg and Tm of the copolyamide are determined as described by ASTM D3418-03, with a heating and cooling rate of 10°C per minute, in which DRMD / DRTD is at least 0.8 and DR MD x DR TD is at least 10. The invention also relates to sequentially stretched biaxially oriented film.
