Abstract

The utility model provides a transfer printing film which consists of a base material layer and a printing layer, wherein the printing layer comprises a transparent ink layer and a common printing ink layer. The transfer printing film is simple in structure, does not need a strippable layer and also can prevent the image layer on the surface of a printing stock completing transfer operation from stripping caused by the inexistence of a protective layer. The printing products printed by the transfer printing film has the advantages of exquisite patterns and no stripping in the image layer; the transfer film printing is simple in structure and has no pollution to environments; and the manufacturing cost is greatly saved.

Description

A kind of transfer film

Technical field

The utility model relates to a kind of transfer film, especially a kind of transfer film that directly on multicolour press, is superposeed and print continuously by base material.

Background technology

With the printing process of the corresponding pressure transfer of picture and text utilization on the intermediate carrier film to the stock; Be called transfer printing; And different according to the method that adopts, transfer printing can be divided into: hot transfer printing, water transfer printing, cyclostrophic seal, full figure printing, silk screen transfer printing or low-temperature transfer printing etc.

With reference to TaiWan, China patent application case number No. 095102148 described transfer film; It is meant and a kind ofly furls in axle that glutinous transfer film can not take place to be stained with each other its pattern when hiding, forms comprising one transparent (or opaque) basalis, a release layer, a kind of glued membrane or induction glued membrane and an image layers of melting.The structure of transfer film is a basic unit among the Chinese patent ZL200510027809.2, strippable coating and printed layers, and its strippable coating adopts the releasing agent of organosilicon series; Or the nonabsorbable film, still, no matter which kind of material strippable coating (release layer) adopts; The existence of strippable coating all can bring pollution and cause waste to environment; Simultaneously, the image layers of accomplishing the stock surface of transfer printing operation is subject to external factor (like oxidation, corroding etc.) and produces and defective such as peel off.

Summary of the invention

The purpose of the utility model is to overcome the defective of above-mentioned two kinds of structure transfer films, can not adopt three layers or multilayer transfer membrane structure, can save strippable coating, and the image layers on the stock surface of order completion transfer printing operation can not produce and peel off again.It is a kind of for realizing that trans-printing in rule or irregular surface product, adopts the transfer film with double-layer structure that the utility model provides.

In order to reach the purpose of the utility model; The technical scheme that the utility model adopts is: on 20 microns ~ 120 microns PVC films of thickness directly with intaglio plate in India side formula printing layer of transparent printing ink, it is one of following that above-mentioned transparent ink can adopt: ethanol-soluble type resin transparent printing ink, solvent-type acrylic transparent ink, polyurethane look black.Adopt India side formula in the set type intaglio plate, the forme roller number is N, between 1 between the maximum forme roller number of polychrome printing machine, polychrome printing ink is repeatedly printed, and last and transparent ink forms printed layers jointly, thereby accomplishes the making of two-layer transfer film.

According to the material of stock, above-mentioned transfer film can coating solvent type gum, and directly applies to hot transfer printing, the purposes that mold-in injection shifts.Gum layer can be directed against thermoplastics such as ABS, PP, PE specially.Or glue-spreading not, the exquisite pattern of trans-printing on PU expanded material stock.

Adopt above transfer film to shift the finished product printed patterns fineness that seal obtains, image layers can not peeled off, and because transfer film is simple in structure, does not have environmental pollution, has practiced thrift product cost.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explanation.

Embodiment 1

Among Fig. 1, at thickness be on 60 microns the transparent PVC film 1 directly with intaglio plate in the India side formula print ethanol-soluble type resin transparent printing ink, its component is a PVB polyvinyl butyral resin 2%, pure dissolubility levelling agent 0.5%; Methyl alcohol 60%, isopropyl alcohol 34.5%, or solvent-type acrylic transparent ink; Its component is a plexiglass 15%, Nitro cellulose resin 3%, levelling agent 0.5%; Butanone 66.5%, xylenes 15% adopts India side formula in the set type intaglio plate again; As shown in Figure 2, the forme roller number is N, between 1 between the maximum forme roller number of polychrome printing machine; Polychrome printing ink is repeatedly printed, and last and transparent ink forms ink lay 2 jointly, thereby accomplishes the making of transfer film;

2, the transfer film that prints is carried out plastics sucking moulding with the supine mode of printing ink on Packing Machine, as shown in Figure 4.160 ~ 200 ℃ of plastic uptake temperature.5 ~ 8 seconds heat time heating times, vacuum time 2 ~ 5 seconds obtains one group of a plurality of and same or analogous plastic uptake film of product-forming, and is as shown in Figure 5;
