Abstract
The invention discloses a preparation method of a film coating and transfer printing Fresnel lens and a product obtained by the preparation method. The conventional Fresnel lens preparation process adopts a method that mould pressing is directly carried out on a PVC (polyvinyl chloride) film or a UV (ultraviolet) layer is coated on a PET (polyethylene terephthalate) film and then mould pressing is carried out. The preparation method comprises the following steps: selecting a film carrier, spraying a high-temperature melted PE material, and forming the Fresnel lens through pressing. Compared with the conventional method, the preparation method is low in cost and high in efficiency. After being aluminized, the lens film produced according to the method is applied to high-grade anti-counterfeiting composite film packing of high-grade cigarette packets, exported lamps and cosmetics, and has the aesthetic and anti-counterfeiting effects.
Description
Technical field
The invention belongs to technical field of packaging and printing, specifically a kind of preparation method of film transfer printing Fei Nier lens and the Fei Nier optics of lens film that makes by the method.
Background technology
Luxuriant and rich with fragrance Neil lens coating is again opal film, 3D cold lamination film, is the modish decoration packaging material in a kind of world.Luxuriant and rich with fragrance Neil lens coating is a kind of optical lens array imaging film, and third dimension is strong, and transparency is high, has lens wide-angle effect, and downscaled images, broadens one's vision, and can reflect and observe the several images that dwindle of thing, because of the similar opal of viewing effect, therefore claim opal film.Luxuriant and rich with fragrance Neil lens belong to dark lines impression optical design, and depth of lines reaches 2.5 μ m, has good attractive packages and antifalse effect.
Traditional handicraft is prepared Fei Nier lens method, and one for directly to impress on the PVC film of thickness 40-50 μ m; It is two for to apply UV glue on PET or BOPP film, after impression again by UV illumination curing.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defect that above-mentioned existing luxuriant and rich with fragrance Neil lens preparation technology exists, a kind of preparation method of film transfer printing Fei Nier lens is provided, its use PE film replaces PVC film directly to impress or UV light is consolidated, to simplify production process, enhance productivity, reduce production costs.
For this reason, the present invention adopts following technical scheme: a kind of preparation method of film transfer printing Fei Nier lens, and its step is as follows:
1) selective membrane carrier: selecting thickness is the PET corona film of 12 ~ 20 μ m, corona surface surface tension value >=50dyn; Selecting the reason of PET corona film is because PET has good resistance to elevated temperatures and hot strength, and corona surface >=50dyn is in order better to make PE coating and the laminating of PET corona film surface.
2) spray PE coating: the extrusion molding application type PE material that is 2 ~ 8 in PET corona film corona surface spray melt index, forms PE coating; Select the PE material of melt index 2 ~ 8, but not other PE materials are to get its good extrusion molding paintability.
3) impression solidifies: by chill roll impression the cooling curing PE coating of coated Fei Nier optics of lens microscopic carvings nickel version.
Further, the melt temperature of PE material is 120 ~ 130 ℃; PE coating layer thickness is 4 ~ 5 μ m; The thickness of PET corona film is 115 μ m.
Further, the laminate pressure of described chill roll and PET corona film is 0.4 ~ 0.5Mpa, and in chill roll, logical temperature is the cooling water of 20 ~ 25 ℃, also can realize by other means.
The method of the invention is compared the existing method of the first, and because the present invention adopts the PET corona film of thickness 12 ~ 20 μ m, thickness reduces, cost, and also the present invention can be common on PET, BOPP or other basement membranes and make Fei Nier lens coating, and applied widely.Compare the existing method of the second, the present invention is without adopting high UV glue and UV light irradiation apparatus thereof, and compares the solid mode of UV light, and during production, the speed of a motor vehicle can be brought up to 80-100m/min by 15-20m/min, and efficiency also improves thereupon.
The Fei Nier optics of lens film that preparation method of the present invention makes, its minute is upper and lower two-layer, and wherein the thickness of PE coating is 4 ~ 5 μ m, and the thickness of PET corona film is 12 ~ 20 μ m.The Fei Nier optics of lens film that the present invention makes is mainly used in, in the packing of high-grade cigarette, outlet light fixture and cosmetics etc., including but not limited to above several respects.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Fig. 2 is the structural representation of the Fei Nier optics of lens film prepared of the present invention.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments, the invention will be further described.
The preparation method of film transfer printing Fei Nier lens as shown in Figure 1, its step is as follows:
A. selective membrane carrier: selecting thickness is the PET corona film (being called for short PET film) of 15 μ m, corona surface surface tension value >=50dyn.
B. spray PE coating: film installs roller platen additional by conventional film machine and realizes, and PE coating is coated on the corona surface of PET corona film, and THICKNESS CONTROL is at 4 ~ 5 μ m, and the speed of a motor vehicle is 80-100m/min, specifically according to melting PE velocity of flow adjust.
C. impression solidifies: with chill roll impression the cooling curing PE coating of coated Fei Nier optics of lens microscopic carvings nickel version, logical recirculated cooling water in chill roll, water temperature is 20 ~ 25 ℃ and is advisable.
As shown in Figure 2, the Fei Nier lens coating of preparing by said method divides two-layer up and down, and wherein PE coating 1 is thick is 4 ~ 5 μ m, and PET corona film 2 thickness are 15 μ m, and this lens coating can be directly used in makes Fei Nier lens composite membrane.
