Abstract

The invention belongs to the field of thin films, and particularly relates to a label film. The PP label film is characterized in that a coating layer, a PP thin film, an aluminum layer, a glued layer and a base material are sequentially arranged to make the PP label film be of an integral structure; materials of the coating layer is formed by mixing matrix resin, reactive diluents, deionized water, a defoaming agent, a flatting agent and wetting dispersants, the raw materials comprise, by weight, 16-70 parts of the matrix resin, 10-55 parts of the reactive diluents, 9-50 parts of deionized water, 0.3-0.8 part of the defoaming agent, 0.4-1 part of the flatting agent and 0.4-1.2 parts of the wetting dispersants, and the thickness of the coating layer ranges from 0.5 micrometer to 1 micrometer; the thickness of the PP thin film ranges from 45 micrometers to 50 micrometers; the thickness of the aluminum layer ranges from 401 angstroms to 500 angstroms. The printing ink of the label film is good in adhesive force, and greasy dirt can be prevented from generating on the surface of the label film.

Description
