Problems solved by technology
Transfer (gold) and silver cards are easy to process, but due to their simple appearance and lack of designability, they are mostly used in low-end cigarette product packaging; although transfer laser (gold) and silver cards have various appearances and strong visual effects, they have certain Decoration and anti-counterfeiting functions are mostly used in middle and high-end products. However, because the production process of laser plates is relatively complicated, a series of processes such as electronic document production, laser engraving, electroforming, and reprinting are required. The production cycle is relatively long and the controllability is not high. And The subsequent molding process requires high temperature and high pressure production conditions, which consumes a lot of energy and costs relatively high

Embodiment Construction
[0015] Such as figure 1 , shown in 4, the manufacture method of dynamic image transfer film is as follows: coating release layer 2 on PET base film 1, thickness is 2-3 micron, dry afterwards; Make the electronic file that contains dynamic pattern information, pass laser engraving machine Engraving the dynamic pattern information on the roller; coating UV varnish on the release layer 2, the thickness is 4-5 microns, the pressure value of the coating roller is 0.15-0.35Mpa to form a UV varnish layer, and then through printing Transfer the dynamic pattern information on the drum to the UV varnish layer to form a UV varnish layer 3 containing dynamic pattern information; use two UV lamp tubes to irradiate the UV varnish layer 3 containing dynamic pattern information on the UV varnish layer 3 to thoroughly Drying, the power of each ultraviolet lamp is 11-13KW; the obtained transfer film is rolled up, and the tension value during winding is 3.5-5.5 Newton; Aluminum is vacuum-coated...

The invention discloses a transfer film applied in cigarette package use paper and a production method thereof. The prior transfer silver (gold) card has a single appearance performance form and is lack of creativity; and the production process of transfer laser silver (gold) card is relatively complicated and the production period is relatively long. The production method of the transfer film comprises the following steps of (1) applying releasing layer on a base film and drying, (2) producing electrical document with dynamic pattern information and carving the dynamic pattern information on a roller through a laser carving machine, (3) applying UV gloss oil on the releasing layer of the base film so as to form a gloss oil layer, and transferring the dynamic pattern information on the roller to the UV gloss oil layer through printing to form an UV gloss oil layer containing dynamic pattern information, (4) drying the UV gloss oil layer under the irradiation of a UV light, (6) and plating aluminum in a vacuum manner on the UV gloss oil layer to form an aluminum layer. The dynamic pattern transfer film provided by the invention greatly increases the competitiveness of product and has short production period.
Description
technical field [0001] The invention relates to the field of packaging materials, in particular to a transfer film used in cigarette packaging paper and a production method thereof. Background technique [0002] Transfer film is a very widely used material in cigarette packaging paper at present. After it is compounded with paper, peeled off and cut, it can be used in the printing process of cigarette packaging. Common transfer film and laser transfer film are widely used in transfer film. Common transfer film is the simplest kind of transfer film. Its production process includes PET base film coating release layer and vacuum aluminum plating, and then ordinary transfer film Film and paper lamination, stripping, varnish, slitting to make transfer (gold) and silver cards; the production process of laser transfer film includes PET base film coating release layer, molding, vacuum aluminum plating, and then laser transfer film is also combined with paper Lamination, peeling, va...
