Problems solved by technology

[0005] The present invention aims at the defect that the current Finier lens film-coated paper cannot adapt to the environmental protection requirements of high-grade tobacco and export lamps and cosmetics anti-counterfeiting packaging, and provides a preparation method for Finnel lens vacuum aluminized paper to produce High-grade optical anti-counterfeiting packaging aluminized paper with the same effect as lens film laminating paper, and the finished paper is easy to degrade and meets environmental protection requirements. The base film can be reused more than 10 times, reducing costs and improving work efficiency

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] The preparation method of this Fresnel lens vacuum aluminized paper, as shown in Figure 1, its step is as follows:

[0032] A. Select a membrane carrier: select a BOPP cold transfer base membrane with a thickness of 50 μm.

[0033] B. Embossing permanent Fresnel lens optical film: Install the Fesnel lens working nickel plate on the cat's eye film embossing machine, set the temperature of the preheating roller to 75°C, preheat the BOPP base film and carry out deep pattern embossing, The bonding pressure of the rubber roller and the base film is 0.45 MPa, and a permanent lens optical film with Fresnel lens embossing is obtained after embossing.

[0034] C. Select paper substrate l: select 60g / m copper plate paper as the paper substrate l.

[0035] D. Forming Fresnel lens optical paper: with BOPP Fresnel lens optical film as the carrier, ...

Abstract

The invention discloses a preparation method of Fresnel lens vacuum aluminized paper and a produced product thereby. Present technology can only produce Fresnel lens composite film and laminating paper which cannot degrade in a short period, and thus do not meet requirements of environmental protection, and cannot be used for tobacco packaging and environmentally-friendly packaging for high-end exports. The preparation method comprises steps of: selecting film carrier; imprinting permanent Fresnel lens optical film; selecting paper substrate; forming Fresnel lens optical paper; aluminizing under vacuum; and coating a surface coating layer and a back coating layer, thereby obtaining the Fresnel lens vacuum aluminized paper. The method can produce the high-end packaging aluminized paper which has optical patterns of Fresnel lens, is anti-counterfeiting, environmentally-friendly and high in gloss, and can be used for high-end cigarette packets and export lamps and cosmetics; the finished paper is degradable, low in cost and high in work efficiency.

Description

technical field [0001] The invention belongs to the technical field of packaging and printing, and relates to a method for preparing vacuum aluminized paper and the vacuum aluminized paper prepared by the method, in particular to vacuum aluminized Fresnel lenses used in high-grade cigarettes, export lamps and cosmetic packaging boxes The preparation method of the paper and the prepared Fresnel lens vacuum aluminized paper. Background technique [0002] Metallized packaging paper is mainly divided into: aluminum foil composite paper (first generation), 0.006 mm aluminum foil and paper lamination, originated in the early 1990s, its disadvantage is 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 bonded with paper after spraying aluminum, which originated in the mid-1990s. Its disadvantage is that PET / OPP film cannot be...
