| abstract |
The present invention relates to print film field, in particular to a kind of water-based ink print film and preparation method thereof.Water-based ink binder in water-based ink of the present invention uses water-based polyurethane latex, enhances ink and adhesion of thin film, keeps water-based ink stability stronger, and water-based ink is made to have stronger resistance to migration；Design the formula of film layer, film layer is set to be suitable for printing water-based ink, improve the compatibility of water-based ink and film, not plasticizer-containing in film layer raw material, EEA particle is added in formula, effectively improves the toughness and thermal stability of film for the problem of there is no plasticizers, opening agent is free of in formula, prevents opening agent and low molecule material that film surface is precipitated and influences stability of the water-based ink on film. |
