Abstract
The utility model discloses a PU (polyurethane) heat transfer printing lettering film, which comprises a PET (polyethylene terephthalate) base layer, a release layer, a polyurethane adhesive layer, a protective layer and a hot melt adhesive layer, wherein the PET base layer, the release layer, the polyurethane adhesive layer, the protective layer and the hot melt adhesive layer are sequentially arranged, a lettering base layer formed by high-ductility metal is arranged between the protective layer and the hot melt adhesive layer, the high-ductility metal adopts an aluminum foil film, the lettering base layer is adhered with the protective layer and is pressed by a mould pressing process to form concave-convex grains.
Description
Technical Field
The utility model relates to a PU thermal transfer lettering film.
Background
The thermal transfer printing is a transfer printing technology and a product, and is a technical form of printing patterns and images on thermal transfer printing paper on different material media through heating transfer by using a thermal transfer printing device, and with the improvement of living standard, some young people pursue more individual pattern display, so that the development of various forms and effects of lettering films becomes a direction to be researched by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide a PU thermal transfer lettering film with reasonable structural design.
The technical scheme adopted by the utility model for solving the problems is as follows: the utility model provides a PU thermal transfer membrane of carving characters, includes PET basic unit, leaves type layer, polyurethane glue film, protective layer and hot melt adhesive layer, PET basic unit, sets gradually from type layer, polyurethane glue film, protective layer and hot melt adhesive layer between be provided with the portrayal basic unit that the high extension metal constitutes, portrayal basic unit and protective layer adhesion link to each other and form unsmooth line through the suppression of mould pressing technology, polyurethane glue film attach on the protective layer, the protective layer still be provided with the ink printing layer and laminate in the high extension metal, through the color pattern of protective layer setting with unsmooth line adaptation.
Further: self-luminous particles or reflective particles are arranged between the high-extensibility metal and the protective layer.
Further highly ductile metals use aluminum foil films.
Further the PET basic unit adopt the glass fibre reinforced PET layer.
The protective layer is a polypropylene film.
Compared with the prior art, the utility model has the following advantages and effects: the lettering film has reasonable structural design and distinct layers, wherein the protective layer is combined with the high-extension metal to carve the relief patterns in the concave-convex state to form the concave-convex effect, and the protective layer can be sprayed with the patterns matched with the concave-convex pattern and provided with self-luminous particles or reflective particles, so that the visual effect of the concave-convex pattern is improved.
Drawings
FIG. 1 is a schematic structural diagram of a PU thermal transfer lettering film according to an embodiment of the utility model.
The reference numbers: the PET substrate 101, the release layer 102, the polyurethane adhesive layer 103, the protective layer 104, the hot melt adhesive layer 105, the engraving substrate 106 and the ink printing layer 107.
Detailed Description
The present invention will be described in further detail below by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not to be construed as limiting the present invention.
Referring to fig. 1, this embodiment a PU heat transfer membrane of carving characters, including PET basic unit 101, from type layer 102, polyurethane glue film 103, protective layer 104 and hot melt adhesive layer 105, PET basic unit 101, from type layer 102, polyurethane glue film 103, protective layer 104 and hot melt adhesive layer 105 set gradually, protective layer 104 and hot melt adhesive layer 105 between be provided with the sculpture basic unit 106 that the high extension metal constitutes, the high extension metal adopts the aluminium foil membrane sculpture basic unit 106 and protective layer 104 adhesion and form unsmooth line through the mould pressing technology suppression, polyurethane glue film 103 attach on protective layer 104, protective layer 104 still be provided with printing ink printing layer 107 and laminate in the high extension metal, set up the color pattern with unsmooth line adaptation through protective layer 104.
The embodiment relates to a lettering film, which is applicable to, for example, personal clothing: the personalized T-shirt, the advertising umbrella, the apron, the hat, the traveling bag of a travel agency, the numbers and the marks of a factory and a school, etc. in the structure, the lettering film has reasonable structure design and clear level, wherein the protective layer 104 is combined with the high-ductility metal to carve the relief pattern in a concave-convex state to form a concave-convex effect, self-luminous particles or reflective particles are arranged between the high-ductility metal and the protective layer 104 to improve the visual effect of the concave-convex, the PET base layer adopts a glass fiber reinforced PET layer and is based on the glass fiber reinforced PET layer, the protective layer 104 is a polypropylene film, has good heat resistance and ageing resistance, can effectively reduce the thermal shrinkage rate of the lettering film and ensure the engraving effect of the relief pattern, the embossing die has good tensile property and transparency, and is effectively suitable for being attached to high-ductility metal to perform embossing process and display of printed patterns.
The above description of the present invention is intended to be illustrative. Various modifications, additions and substitutions for the specific embodiments described may be made by those skilled in the art without departing from the scope of the utility model as defined in the accompanying claims.
