Embodiment 1

[0037] A transfer type laser embossed polyester film (or laser transfer embossed film), its film structure is a three-layer co-extruded composite structure, such as Figure 4 Shown: The new polyester film has a three-layer layered structure, and its upper surface layer is made of amorphous PET polyester, SiO 2 Transfer-type laser imprinting layer formed by additive-type PET polyester and polysiloxane release agent; transfer-type laser imprinting layer is directly co-extruded and compounded with PET polyester homopolymer, SiO 2 The core layer of additive-type PET polyester; the other surface of the core layer is directly co-extruded and compounded with PET polyester homopolymer, SiO 2 Lower skin layer of additive PET polyester.

[0038] The new polyester film is produced by a co-extrusion biaxial stretching process.

[0039]The sources of raw materials used in the following are: Amorphous PET polyester chips were purchased from Eastman, USA, model Easter6763; PET polyester ho...

Abstract

The invention provides a transfer type laser impressing polyester film and a preparing method thereof. The novel polyester film is provided with a three-layer laminated structure, the upper surface layer is a transfer type laser impressing layer formed by non-crystal type PET polyester, SiO2 additive type PET polyester and polysiloxane mould release agent. The transfer type laser impressing layer is provided with a core layer in a direct coextru-lamination mode, wherein the core layer is formed by PET polyester homopolymer and SiO2 additive type PET polyester. The other surface of the core layer is provided with a lower surface layer in a direct coextru-lamination mode, wherein the lower surface layer is formed by PET polyester homopolymer and SiO2 additive type PET polyester. The transfer type laser impressing layer in the film is compared with a transfer type laser impressing layer produced through a conventional coating method, a clearer hologram image is obtained after impressing, richness and integrity of image information are ensured, higher brightness is achieved, the impressing image can be transferred, and therefore the transfer type laser impressing polyester film has high market application value.

Description

(1) Technical field [0001] The invention relates to a functional polyester film and a preparation method thereof, in particular to a polyester film which can directly carry out laser embossing on one surface of the polyester film and transfer the laser embossing image to other carriers. (2) Background technology [0002] In the past ten years, with the development and progress of biaxially oriented polyester film production technology, various functional polyester films have begun to enter the market and are widely used in various industrial fields and people's social life. [0003] The so-called functional polyester film is that in addition to the basic properties of the original polyester film, through the improvement of raw materials, formulas, and production processes or other production technology means, the produced polyester film has the basic properties of the original polyester film. or functions in addition to additional performance or functions. [0004] Laser em...
