Abstract

The invention discloses a direct inkjet printing biaxial stretching polyester film and a preparation method thereof. The polyester film comprises a printing layer film and a base layer film. The preparation method comprises the following steps of: firstly preparing a printing layer film polyester raw material, then carrying out drying treatment on the prepared printing layer film polyester raw material and a base layer film polyester raw material, performing two-layer coextrusion to form a casting piece, carrying out longitudinal stretching and transverse stretching, pulling, rolling, and finally obtaining the direct inkjet printing biaxial stretching polyester film. The direct inkjet printing biaxial stretching polyester film prepared by the method does not need a coating, can be directlyused as inkjet printing-supplies, has excellent mechanical properties and ink absorbing property, long service life and low cost, and can replace a large number of commonly used inkjet supplies.

Description

technical field [0001] The invention relates to the field of polyester films, in particular to a polyester film capable of direct inkjet printing and a preparation method thereof. Background technique [0002] Inkjet consumables are a product with a very large consumption. Expressway advertisements, city publicity large-scale pictures, light box decorations and indoor and outdoor decoration pictures are all downstream markets of inkjet printing consumables. At present, these inkjet consumables are mainly divided into two types, namely soft PVC, printing coating / BOPP or BOPET. BOPET (biaxially oriented polyethylene terephthalate) film is a polymer film with excellent comprehensive properties, especially excellent optical transparency and mechanical strength. However, because the molecular structure of BOPET is rigid and the molecules are closely arranged, BOPET does not have ink absorption performance, and it must be combined with the printing coating to achieve painting. ...
