Abstract
A directly embossable, coated polyethyleneterephthalate film including a dry, uniaxially oriented PET film, and a coating applied to the PET film, wherein the coating and the PET film have as a composite been transversely stretched, the coating resin being capable of impregnating the PET surface on drawing, rendering the film surface susceptible to embossing under pressure and the coating having low heat sealability and a method of producing a coated, directly embossable polyethyleneterephthalate film.

16. A method of producing a coated, directly embossable polyethyleneterephthalate (PET) film comprising:
-
stretching a PET film to form a uniaxially oriented PET film;
drying the uniaxially oriented PET film;
coating at least one surface of the uniaxially oriented PET film with an aqueous solution of an organic material; and
rendering at least one surface of a resulting coated uniaxially oriented PET film susceptible to direct embossing by impregnation of the surface of the uniaxially oriented PET film with at least a portion of the coating by transverse stretching the coated uniaxially oriented PET film. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of producing a directly embossable substrate having low heat sealability comprising:
-
inline coating a uniaxially oriented PET film with about 0.1 μ
m to about 0.4 μ
m in thickness of a non-crosslinked polystyrene-acrylic emulsion or non-crosslinked polyester dispersion;
drying the coating; and
transverse stretching the resulting coated film.
