Historyofdevelopment

Inthe1930s,self-adhesivematerialswerefirstappliedintheUnitedStates,duetothegrowingdemandforthisspecialcompositematerialTherefore,self-adhesiveprintinghasgraduallyevolvedintoanindependentprintingfield,andmoreandmorecompaniesareengagedinself-adhesivelabelprintingathomeandabroad.Asfarasmycountryisconcerned,theunprecedenteddevelopmentoftheprintingindustryintermsofproductionscale,technicallevel,andmarketspacehasdriventhedevelopmentofself-adhesiveprintingandhasreachedanunprecedentedlevel.

Accordingtostatistics,in2011,theoutputvalueofmycountry’slabelmarketwasRMB23billion,andthelabeloutputwas3billionsquaremeters,anincreaseof21.1%and20.0%respectivelycomparedto2010(theoutputvalueofthelabelmarketin2009was19billionYuanRenminbi,labeloutputis2.5billionsquaremeters).Inthesameyear,mycountry'slabelsaccountedfor6.4%ofgloballabelproduction.Therefore,mycountry'sself-adhesivelabelmarkethasgreatpotential.

Theearliestself-adhesivewasproducedinthehandsofachemistfrom3MCompanyintheUnitedStates.Itwasin1964.Atthattime,whenhewasresearchingvariousadhesiveformulations,heformulatedanewtypeofadhesivewithgreaterviscositybutnoteasytocure.Useittopastethings,evenafteralongtimecanbeeasilypeeledoff.Atthetime,peoplethoughtthatthiskindofviscosewouldnotbeveryuseful,sotheydidn'tpaymuchattentiontoit.

In1973,anewproductdevelopmentteamof3Mcompanyappliedthisgluetothebackofcommonlyusedtrademarks,andthengluedapieceofpapercoatedwithatraceofwaxontheglue.Inthisway,theworld'sfirstlabelpaperwasborn.Asaresult,theroleofself-adhesivehasbeendiscoveredbypeopleoneafteranother,andmoreandmorepeopleareusingself-adhesive.

Checktheappearance

Inordertoavoidasmuchaspossibletheself-adhesivecausedbythequalityoftheself-adhesivematerialitselfForlabelprintingfailures,itisnecessarytocarefullychecktheappearancequalityoftheself-adhesivematerialbeforeprinting,sothatdefectsthatmaycauseprintingqualityproblemscanbediscoveredintimebeforeprinting.

1.Checkwhethertheself-adhesivematerialhasburrs

Theedgeoftheself-adhesivematerialontherollissmoothandundamaged.Itisthebasisforensuringthequalityoftheself-adhesivelabelprinting.Therefore,printingBeforeprocessing,besuretocarefullycheckwhethertheslittingedgeoftherollofadhesivematerialhasburrs,whetheritisdamagedduetoimproperstorageandtransportation,androlltherollofadhesivematerialdown4-5times,andcarefullycheckthedivision.Cuttheedges.

2.Checkwhethertherearecracksontheself-adhesivematerial.

Whentheself-adhesivematerialiscut,ifthecuttingtoolisnotadjustedproperlyorthebladeisnotsharpenough,itwillnotdryCracksappearonthetoppaperorbottompaperofthegluematerial,andthefiberspulledoutfromthecrackswillbestuckbytheadhesive.Theoccurrenceofcracksmaybecontinuousorrandom.Theremaybeonesideoftherollofadhesivematerial,orbothsides.Therefore,beforetheadhesivematerialisprintedonthemachine,youmustcarefullycheckthebackingpaperandWhethertherearesmallcracksonthetissue.

3.Checkwhethertheedgesoftheself-adhesivematerialarestuckandwhetherthebackingpaperismissingsilicon

Theedgesoftheself-adhesivematerialarestuckorthereisapartofthebackingpaperthatismissingsiliconeoil.Duringtheprocessing,thetissuepaperwillbreakduringthewastedischarge,andthenormalproductionwillnotbepossible.Therefore,beforeprinting,takealengthofabout1meterofself-adhesivematerialandpeelitoffbyhandtoseeifthereisanypartthatcannotbepeeledsmoothlyanduniformlyontheedgeorotherparts.Usually,theedgeadhesionbetweenthefacepaperandthebottompaperoccursonaslitrolloftheentirerollofcoatedself-adhesivematerial,andgenerallyonlyoccursattheouterlayerof7to10meters.Therefore,whenencounteringaslitrollThereisadhesionontheedgeoftheself-adhesivematerial.Don'timmediatelyassertthattheentirerollofpaperhasthisproblem.
