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.

Embossable thermoplastic polyester film and method for producing the film

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 film being coated from an aqueous solution at a thickness of about 0.1 &mgr;m-about 0.4 &mgr;m with a non-crosslinked polystyrene-acrylic emulsion and non-crosslinked polyester dispersion, the Tg of the coating resin being greater than about 20&deg; C. and less than about 70&deg; C., 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 including uniaxially stretching a polyterephthalate film to form a uniaxially oriented polyethyleneterephthalate film, drying the uniaxially oriented polyethyleneterephthalate film, coating at least one surface of the uniaxially oriented polyethyleneterephthalate film with an aqueous solution of an organic material, drying the coating to form a coated uniaxially oriented polyethyleneterephthalate film, rendering at least one surface of the coated uniaxially oriented polyethyleneterephthalate film susceptible to direct embossing by impregnation of the surface of the uniaxially oriented polyethyleneterephthalate film with at least a portion of the coating by transverse stretching the coated, uniaxially oriented polyethyleneterephtlate film.

Coated film with exceptional embossing characteristics and method for producing it

Ultra low haze, co-extruded, thermoplastic polymer film prepared by co-extrusion of a blend of polyethyleneterephthalate with organic and inorganic fillers in at least one skin layer on a virtually particle-free polyethyleneterephthalate core layer; the inorganic fillers are aluminum oxide particles and/or silicon oxide of average particle size of about 0.035 &mgr;m to about 0.3 &mgr;m, and wherein particles of the organic filler have a particle size of less than or equal to about 0.8 &mgr;m and are present in an amount less than about 0.04% by weight, based on the weight of the polyethyleneterephthalate, the skin layer being less than about 3 &mgr;m in thickness.

Easy handling ultraclear thermoplastic film
