Abstract

The invention discloses a safe and environmentally friendly dedicated composite ink for preserved vegetable packaging bag and preparation method of the composite ink, wherein the dedicated composite ink mainly comprises the raw materials of A of chlorinated EVA (ethylene vinyl acetate) resin solution, chlorinated polyether resin solution, a dispersing agent and esters solvent, B of rutile titanium dioxide / organic pigments and a matting agent, and C of ester dissolved chlorinated polypropylene resin solution, solubilizers and the like. The preparation method comprises the following steps of pre-dispersing the raw materials, sanding, adjusting ink and the like. According to the invention, the ink product is the benzene-free environmentally friendly inks by using imported ester dissolved chlorinated polypropylene resin as the main binder and does not contain benzenes and ketones organic solvents, is extremely low in solvent residue and can meet the requirements of boiling and sterilizing of the OPP (oriented polypropylene) / / VMPET (biaxially-oriented polyethylene terephthalate) / / PE (poly ethylene) structure packaging bags.

Description

technical field [0001] The invention relates to a composite ink, in particular to a safe and environment-friendly special composite ink for mustard mustard packaging bags and a preparation method thereof. Background technique [0002] With the development of flexible packaging technology, mustard mustard packaging generally needs to be sterilized after vacuuming to prolong the shelf life. With the continuous expansion of market applications, until today, most of them have adopted the material structure of OPP / / VMPET / / PE, mustard mustard packaging Different from ordinary light packaging, it has certain particularity in material selection. After flexible packaging enterprises choose OPP / / VMPET / / PE and glue that meet the requirements, the choice of ink is very important. [0003] At present, the benzene-free inks that can be used for mustard packaging and printing in the industry include modified chlorinated polypropylene system, polyurethane system and alcohol-water system ink...
