Abstract

The invention discloses a preparation method of matte aluminum-plated paper. The preparation method comprises the following steps of (1) coating: coating a PET (polyethylene glycol terephthalate) thin film with a matte transfer coating, so as to prepare a matte transfer film; (2) aluminum plating: performing vacuum aluminum plating on the matte transfer film by a vacuum aluminum plating machine, wherein the vacuum degree is 0.2 to 0.3Pa, the temperature is -140 to -160 DEG C, and the thickness of the aluminum layer is controlled to the value shown in the description; (3) compounding: coating the aluminum-plated matte transfer film with a composite glue on a wet coating machine, compounding with bottom paper, and coating the bottom paper with a back adhesive; (4) stripping: separating the compounded and cured aluminum-plated layer of a product from a substrate PET thin film on a stripping / coating dual-purpose machine, and transferring to the surface of the bottom paper, so as to obtain the matte aluminum-plated paper. The prepared matte aluminum-plated paper has the advantages that the color fusion of the paint film is avoided, the color phase is uniform, the printing suitability is good, the production effect is effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of composite packaging materials, and in particular relates to a matte aluminized paper and a preparation method thereof. Background technique [0002] Metallized packaging paper is mainly divided into: aluminum foil composite paper (first generation), 0.006mm aluminum foil and paper lamination, originated in the early 1990s, its disadvantages are that the aluminum layer and paper cannot be separated, and papermaking cannot be recycled, and the thickness of the aluminum layer is difficult Degradation; laminated paper (second generation), PET / OPP film is laminated with paper after spraying aluminum. It originated in the mid-1990s. Its disadvantage is that PET / OPP film cannot be separated from paper, and it can neither be recycled for paper making nor can it be degraded in soil ; Vacuum aluminum-coated paper (third generation), originated in the late 1990s, the thickness of the aluminum layer of vacuum metal-coated pape...
