Abstract

The invention relates to a label film paint and a manufacturing method thereof. The label film paint comprises the following components: 90-110 parts of water, 125-140 parts of coarse whiting slurry, 1-4 parts of PVA (polyvinyl alcohol) glue, 31-34 parts of modified acrylic ester polymer emulsion, 28-31 parts of acrylate copolymer emulsion and 0.07-0.18 part of wetting and defoaming agent. The synthetic paper coating prepared from the label film paint obtained by the formula and manufacturing method can be combined firmly with the original film, can not be easily torn off, and does not have the unfavorable phenomena of color cast and ink absorption in printing. Meanwhile, the low-concentration PVA glue added into the label film paint can enhance the viscosity and flowing property of the paint, and can not interfere with the printing effect and fastness of the coating.

Description

technical field [0001] The invention relates to a label film coating and a manufacturing method thereof. Background technique [0002] At present, the paper base for ink printing is generally natural paper, which has poor waterproof and moisture-proof performance and poor weather resistance, which greatly limits its application range. PP synthetic paper has the functionality of plastic materials, is waterproof and dustproof, is not torn, and is durable. However, PP synthetic paper is not a good printing medium for existing inks. The adhesion of ink on PP synthetic paper is poor. A layer of paint is applied on top as an absorption medium for printing inks. Coated PP synthetic paper can be widely used in post-processing fields such as letterpress, gravure, lithography, screen printing, bronzing, cutting, etc., used as business cards, posters, clothing tags, calendars, labels, etc. Commonly known as "label film" and "tear-resistant synthetic paper". Similar products current...
