CN201174027Y - Improved plastic film for stereopicture - Google Patents

Abstract

The utility model relates to an improved stereogram plastic film, which is characterized in that a layer of patterns is printed on the bottom of the plastic film; and the surface of the plastic film is provided with grating fringe grooves which are parallel, equal in length and at equal intervals. In the presence of light rays, the improved stereogram plastic film can generate the physical diffraction phenomenon with changing pictures observed from different angles. Compared with the prior art, the improved stereogram plastic film has the advantages of magically generating a plurality kinds of different pictures, excellent optical effect, firm combination between the pattern layer and a grating resin film layer, saving gluing, raw material, procedures, reducing printing cost, improving production efficiency, and, therefore, can be used for making product advertisement, product packages, handicrafts, gifts, painting albums, and other fields.

Description

Improved stereo-picture plastic film

[technical field]

The utility model relates to the printed decoration technical field, specifically a kind of improved stereo-picture plastic film.

[background technology]

As everyone knows, stereo-picture is made stereoscopic model exactly, produce the printed matter that reproduces the body stereo-picture with three dimensions, its technology mainly is made of stereoscopic photograph, making sheet, printing and back process, in after-processing technology, existing product structure just is stained with film, or stick the film of punching press at the paper left-hand seat that prints on one deck paper that prints.The three-dimensional level of this product structure is not clear, and image effect is poor, and image can not change, and complex manufacturing.

[summary of the invention]

The purpose of this utility model is for overcoming the above problems, make multicolour pattern at utilizing ultraviolet ray or electronic beam curing mode of printing to print on the stereo-picture plastic film back side, by the resin grating striped that cut by the size of packing box, produce the refraction principle of light, make it reproduce the stereo-picture of object, watch in different angles, image also changes thereupon.

For achieving the above object, design a kind of stereo-picture plastic film of novel structure, it is characterized in that forming, be carved with the striped groove on the resin grating film by resin grating film layers and this resin film patterned layer, described grating fringe groove be equidistant, uniformly-spaced, be parallel to each other.Be provided with cut-in groove around assigned address on raster film or the film, can guarantee the stability and the practical value of lenticular lenses like this.This kind organosilicon prepolymer extruding technology is conspicuous to this specialty, and solid section bar material such as stereo-picture plastic film employing PET or PBT or PETG copolyesters or polyacrylic resin or acryl resin or poly terephthalic acid diol ester etc. is made.

The utility model is compared with prior art, clear picture, and stereoscopic sensation is strong, but magic goes out multiple different image, and optical effect is good; Patterned layer combines firmly with the resin grating film layers, no bonding, save starting material, cancel the demand and the direct printing of traditional intermediate medium and bottom material simultaneously, reduce operation, reduce printing cost, enhance productivity, be applicable to and make product advertising propaganda, the packing of product, handicraft, gift, New Year card, Christmas card, picture album etc. to the field.

[description of drawings]

Fig. 1 is the structural representation of the utility model stereo-picture plastic film;

Fig. 2 is the fundamental diagram of the utility model stereo-picture plastic film.

[embodiment]

Referring to Fig. 1, be carved with the striped groove on the resin grating film layers, after incident light reflects through the striped groove, because disappearing mutually and superposition principle of phase of light wave forms stereo-picture.The thickness of stereo-picture film is concerning this professional people, and is still more clearly.A is the resin grating film layers, and B is a printed layers, and C is the cut-in groove of raster film, between the groove be equidistant, uniformly-spaced, be parallel to each other.

Among Fig. 21 is first image, 2 is second image, and 3 is the 3rd image, and 4 is the object that is taken, 6 is camera lens, 7 is compound lens camera, and 8 is egative film, and 9 for cutting apart linear image stick, 10 is compressing image, 11 is transparent film, and 12 is that coating resin, grating amplify pictorial diagram, and 13 and 14 is people's eyes.Fig. 2 has provided fundamental diagram of the present utility model, and the condition of molding of this 3-D view should satisfy the image after the compression.The transparent coating striped of streak shape prism, transparent film, the left side among Fig. 2 shows that an object takes the image 1 and 2 and 3 of three different views of this object via the camera of camera lens more than, image by these three different views, through folk prescription to compression and the compression pattern that is divided into a rule narrow strips shape, these stripeds are exactly 1 and 2 and 3 condensed print stripeds in Fig. 2 right side, watch these printed images this moment is ambiguous, after the streak shape prism transparent film observation that constitutes by transparent film 11 and coating resin 12, the color image of different visual angles can be clearly by the human eye finding, this transparent film is to be used to produce Deep Canvas, and coating resin is to be used for producing the interference of light effect.

The structure that has shown the utility model stereo-picture plastic film in Fig. 1 is made up of the assigned address cut-in groove C of resin grating film layers A and image printing layer B and raster film, the resin grating film layers A that here selects for use is the poly terephthalic acid diol ester, at first adopt the compression moulding organosilicon prepolymer to extrude the resin grating film, and on resin grating film surface, be carved with the striped groove, finish by the described mode of Fig. 2 then and take and compressing image, the image that compression is good adopts ultraviolet ray or electron beam printing mode to be imprinted on the resin grating film back side.Around the raster film that prints or assigned address leave cut-in groove, make different cut-in groove raster films by the packing demand of different product, make the packing of various products again.Having under the situation of light, can produce the diffraction phenomena in the physics, behind resin grating film streak reflex, obtain multi-level, multicoloured stereo-picture, to watch in different angles, image also changes thereupon.

Claims (2)

1. an improved stereo-picture plastic film is characterized in that the bottom of plastic film is printed on a layer pattern, and the surface of plastic film is provided with the grating fringe groove, described grating fringe groove be equidistant, uniformly-spaced, be parallel to each other.

2. stereo-picture plastic film as claimed in claim 1 is characterized in that the stereo-picture plastic film adopts PET or PBT or PETG copolyesters or polyacrylic resin or acryl resin or polyethylene terephthalate gel-type resin material to make.
