Abstract

The invention provides a novel sheet material for packaging and decoration and a manufacturing method thereof, wherein the sheet material is formed by adhering laser paper on the surface of a metal sheet material or a plastic sheet material through conversion adhesive resin HP806, and then coating protective film resin Re3201 on the laser paper, so that the laser paper is tightly adhered with the sheet material and is not easy to fall off, and the decoration and anti-counterfeiting effects of the sheet material are enhanced.

Description

Be used to the sheet material packing, decorate

The present invention relates to a kind of packing, ornamental sheet material, comprise tinplate, stainless steel, aluminium and plastics etc., the invention still further relates to the manufacture method of this sheet material.

Packing, its surperficial pattern of ornamental sheet material adopt the mode of printing or spraying printing ink mostly at present, or between decorating film (material such as plastics, radium-shine paper, paper etc.) and sheet material, use chemical glue, the decoration sheet of this form exists the easy ruined defective of decorative pattern, can only on less area, use for metal sheet simultaneously, and can not on whole surface, use, because can not bearing metal sheet, it is processed into the required punching press of different shape.

The purpose of this invention is to provide and a kind ofly be difficult for destroyedly, robust, use radium-shine paper to make the sheet material of decorative cover.

For achieving the above object, the sheet material that the present invention said is that one deck conversion glue is set between the surface of sheet material and radium-shine paper, and this conversion glue is resin HP806, on radium-shine paper layer protecting film is arranged, and this diaphragm is resin Re3201.

Manufacture method of the present invention may further comprise the steps: place conversion glue (glue name resin HP806) earlier between the surperficial and radium-shine paper of sheet material; through mechanicalness high pressure and heating; wherein Jia Re temperature is that 120 degree are between 160 degree; evenly be coated with last layer resin Re3201 on the surface of radium-shine paper then; and under the temperature of 120 to 160 degree, heated 4 to 10 minutes, form layer protecting film.

Owing between sheet material and radium-shine paper, selected conversion gum resin HP806, it can be glued together radium-shine paper and sheet material preferably, radium-shine paper upper protective film can play interaction with conversion gum resin Re3201 simultaneously, radium-shine paper and sheet material more closely are bonded together, with regard to its bondability, for metal sheet, in its follow-up processing technology, as metal sheet is struck out different shape, comprise the turnover of wide-angle etc., can not cause situations such as sheet material foaming or distortion, simultaneously because its close adhesion effect, even for metal sheet and plastic sheet use long-time after, the radium-shine paper that is adhered to can not come off easily yet; Secondly,, strengthened the decorative effect of sheet material in large area, possessed good antiforge function simultaneously owing to use radium-shine paper to make decorative cover.

As a further improvement on the present invention, on diaphragm resin Re3201, the ink design layer that can also have one deck to print or spray is provided with layer protecting film again on the ink lay, and this diaphragm is a resin 3001.After adopting this structure, on the radium-shine paper of sheet material, can form required pattern, further improve decorative effect.

The manufacture method of this ink lay and second protective layer is as follows: printing ink in printing on the ground floor diaphragm or spraying; form required decorative pattern; then, on ink logo or radium-shine paper, coat second layer diaphragm more equably, and to the temperature of 160 degree, heated 4 to 10 minutes at 120 degree.

The present invention is further detailed explanation below in conjunction with drawings and Examples.

Fig. 1 is the cutaway view of the embodiment of the invention 1.

As shown in Figure 1; the embodiment of the invention 1 described decoration sheet is a tinplate; on tinplate 1 surface; be stained with radium-shine paper 3; radium-shine paper 3 is by the tight stickup of conversion glue 2 (resin HP806) realization with tinplate 1 surface; radium-shine paper 3 can play excellent decoration or antiforge function; scribble layer protecting film 4 (resin Re3201) on this radium-shine paper 3 equably; this diaphragm 4 is the ground floor diaphragm; being the printing-ink 5 of arbitrary graphic pattern on ground floor diaphragm 4, is second layer diaphragm 6 (resin 3001) on it.Owing to selected the specific conversion glue 2 and first diaphragm 4 for use, radium-shine paper 3 can be bonded together with tinplate 1 well, as striking out the shape of various needs, can not occur the situation of any foaming or other distortion in thereafter manufacturing procedure.

The manufacture process of the embodiment of the invention 1; at first stack conversion glue 2 and radium-shine paper 3 successively on tinplate 1 surface; through roll-in and heating; wherein Jia Re temperature is between 120 to 160 degree; evenly be coated with last layer ground floor diaphragm 4 on radium-shine paper 3 surfaces then; baking through 4 to 10 minutes and 120 to 160 temperature; forming surface adhesion has the tinplate sheet material of radium-shine paper 3; the tinplate 1 that again surface is stained with radium-shine paper 3 and ground floor diaphragm 4 is by general ink printer printedink pattern 5; thereafter; onprinting ink 5 or ground floor diaphragm 4 (because some places there is no ink logo on the ground floor diaphragm), be coated with last layersecond layer diaphragm 6 equably; and through roll-in and heating; owing to be stained with radium-shine paper 3 on the tinplate 1; therefore the heating in this process is different from the heating of diaphragm after the printed ink on the common metal sheet material; heating-up temperature be 120 the degree to 160 the degree, be 4 to 10 minutes heat time heating time.

Other metal sheet such as stainless steel, aluminium etc. are roughly the same with resistant to elevated temperatures plastic sheet and tinplate sheet material, also should belong to protection scope of the present invention.

Claims (3)
