Embodiment 1

[0037] An environmentally friendly white ink for POF heat shrinkable film printing, consisting of the following components in mass percentage:

[0038]

[0039]

[0040] Its preparation method is as follows: after weighing the raw materials according to the above ratio, mix them evenly in the mixing tank except gas phase silica, put them into a sand mill for grinding, stop grinding when the fineness reaches below 15 μm, adjust the ink and add Fumed silica, adjust the viscosity to reach the 35-40s of the 4# cup, filter, that is, the obtained ink is "Product A".

Embodiment 2

[0042] An environmentally friendly white ink for POF heat shrinkable film printing, consisting of the following components in mass percentage:

[0043]

[0044]

[0045] The preparation method is the same as in Example 1, and the obtained ink is "Product B".

Abstract

The invention discloses an environment-friendly white printing ink for printing of POF thermal contraction film and a preparation method of the environment-friendly white printing ink. The printing ink consists of the following components in percentage by weight: 20-30% of composite resin, 30-40% of a composite solvent, 30-40% of pigment and 2-4% of a auxiliary, wherein composite resin consists of chlorinated polypropylene resin, acrylic resin, polyvinyl butyral resin and EVA resin in mass ratio of (8-10): (8-10): (3-6): (3-6). After the printing ink cooperates with a POF thermal contraction film for printing, the printed film does not stick back and cause a filling-in phenomenon; printed products are environment-friendly, safe, non-toxic and recyclable; after the printing, the contraction film has strong wear resistance and smoothing property; the shallow version transfer property is excellent; the level reproducibility is good; excellent drying property, kneading resistance and good adhesion are provided; the adhesive force is improved by more than 20%; the blocking resistance is good; the printed products can be reeled; the scraper performance is good; images and texts after the printing do not fade and fall off.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an environment-friendly white ink used for printing POF heat shrinkable films and a preparation method thereof. Background technique [0002] POF heat shrinkable packaging film is the abbreviation of biaxially oriented polyolefin shrink film, which is prepared by biaxially oriented three-layer melt co-extrusion process. This kind of material has a wide range of uses and is fully in line with today's environmentally friendly and non-toxic world consumption trends. It can not only reduce the user's packaging production costs, transportation costs, reduce packaging volume, and greatly improve production efficiency, but also because of its good transparency, it can Improve product visibility. [0003] Compared with traditional heat shrinkable film PVC, it has the following advantages: [0004] 1. Cost advantage, the cost is lower than that of traditional shrink film PVC; [0005] 2. ...
