The invention discloses a production method of a low-
haze vacuum evaporation coating. The production method comprises the following steps of 1, a resin conveying and mixing process, 2, a
melt extrusion process, 3, a longitudinal stretching process, 4, an on-line
coating process, 5, a transverse stretching process, 6, a winding slitting process and 7, a
vacuum coating process. In the step 4, the
surface layer of a film sheet is coated with a
coating in a roller coating mode through an anilox roller, the coating comprises 80-120 parts of
polyester polyol, 2-10 parts of a curing agent, 0.5-3 parts of a catalyst, 1-3 parts of an
aziridine crosslinking agent, 100-150 parts of deionized water and 5-10 parts of isopropanol, a wet coating sheet is obtained, and the thickness of the wet coating is1-5 g / m<2>. According to the production method, through the optimization of the formula of film additives and the
film coating, the
haze of the
vacuum evaporation coating produced under the same production process is reduced, and the coating has better perspective effect and apparent effect, or a product has a wider coating thickness adjustment range on the premise of defining the
haze range of the product.
