Structure

Thestructureofhotstampingpaperisdividedinto:basiclayer,peelinglayer,Colorlayer,electroplatinglayer,gluelayer.

Firstlayer:baselayer

Mattersneedingattention

1.Firstunderstandthesubstrateoftheproduct.Thesubstratethatneedsbronzingdeterminestheseriesofbronzingpaper.Commonlyusedplasticsubstratesthatrequirehotstampingare:ABS,PP,PE,PVC(softandhard),PC,PS,PU,​​TPR,TPU,Saigang,nylon,bakelite,etc.;inaddition,therearepaper(dividedintoCoatedpaper,plainpaper,coatedpaper,etc.),wood(whetherpaintedorlog),leather,clothingprinting,etc.

2.Thedifferencebetweenusinghotstampingprocessandusinghotplate.Flatironingandpipingironing;accordingtothedifferenthotplatesused,therearemetalplatesandrubberplates.

3.Thesizeofthebronzingarea.Mainlyduetothedifferentelasticityofthereleaselayerofthebronzingpaper,thesizeofthebronzingareaisalsoveryimportantfortheselectionofbronzingpaper.Generally,thebronzingpapercanbedividedintofineprintbronzing,smallandmediumareacolorblocks,largeareacolorblocks,andfullareabronzing.Etc.

4.Thehotstampingspeedisdifferent.Whethertouseafullyautomatichigh-speedmachine(thehigh-speedmachinehereisnottheusualso-calledpneumaticautomatic,pneumaticautomaticisactuallyasemi-automaticmachine),semi-automaticmachine,manualmachine,etc.hotstamping.

5.Thechoiceofbrightnessandcolor.Onlyaftertheabove6conditionsaremet,thebrightnessandcolorofthebronzingpaperarefinallyselected.Generallyspeaking,thebrightnessofanodizedaluminumishigherthanthatofpowderfoil,andthebrightnessofanodizedchromiumishigherthanthatofanodizedaluminum.Thebrightnessofhotstampingpaperwithhighthicknessisbetterthanthatofhotstampingpaperwithlowthickness.
