Description

1. Technical field [0001] The invention discloses a water-ink-printed plastic film and a food plastic packaging bag, specifically a preparation method of the ink-water-printed plastic film and the food plastic packaging bag. 2. Background technology [0002] At present, most of the plastic products and food plastic packaging bags used at home and abroad are printed with solvent-based inks. Because it has toluene and methyl ethyl ketone solvent, it will pollute the environment and endanger people's health. In particular, the food packaging country has forced the prohibition of the use of harmful solvents such as toluene and butanone. There are also some alcohol-soluble inks and ester-soluble inks in the printing industry, because it is also a solvent, easy to residue, pollutes the environment and food, as well as waste of resources and unsafe factors. 3. Content of the Invention [0003] In order to solve the above deficiencies, the ink-wash printing of plastic films and ...
