Cov thawv ntawv yog cov khoom siv tseem ceeb hauv kev thauj mus los niaj hnub thiab ntim khoom, thiab lawv txoj kev npaj ncaj qha cuam tshuam rau cov khoom zoo, thauj khoom -cov kabmob muaj peev xwm, thiab kav ntev. Ib qhov zoo- txheej txheem npaj tau tsim tuaj yeem txhim kho kev tsim khoom thiab ua kom muaj kev nyab xeeb ntawm cov thawv thaum thauj thiab khaws cia.
Cov txheej txheem pib nrog kev xaiv cov khoom siv. Cov ntaub ntawv muaj xws li corrugated cardboard, kraft paper, thiab composite boards. Lub thickness, lub zog, thiab qhov yooj yim ntawm cov ntaub ntawv txiav txim siab lub thawv load-cov kabmob muaj peev xwm thiab kev tiv thaiv kev ua haujlwm. Nrog kev loj hlob ntawm ib puag ncig kev paub, cov khoom siv rov ua dua lossis biodegradable tau nce siv hauv lub thawv tsim khoom.
Tom ntej no yog theem tsim. Cov neeg tsim qauv txiav txim siab lub thawv qhov ntev, txoj kev folding, qhib qauv, thiab txheej suav raws li cov khoom loj, qhov hnyav, thiab lub hom phiaj. Cov kev cai luam ntawv tseem raug txiav txim siab, ua kom cov thawv ntawv ua haujlwm rau kev tiv thaiv thiab kev ua lag luam. Kev tsim qauv zoo ua kom zoo rau kev siv cov khoom siv, txo cov khib nyiab, thiab txhim kho kev ruaj ntseg ntawm cov qauv.
Thaum lub sij hawm tsim khoom, lub thawv tau txiav, crease, folding, thiab gluing. Cov kab ntau lawm niaj hnub no feem ntau siv cov cuab yeej siv hluav taws xob kom ua tiav siab - ceev txiav thiab folding, kom ntseeg tau qhov tseeb qhov ntev thiab cov qauv kev ruaj ntseg. Cov thawv tshwj xeeb, xws li ya raws- pov thawj, poob siab- tiv taus, lossis hnyav- lub thawv lub luag haujlwm, tuaj yeem raug kho ntxiv los txhim kho kev ua haujlwm.
Printing thiab nto finishing yog cov kauj ruam kawg. Cov txuj ci xws li offset, flexographic, lossis digital luam ntawv tso cai rau cov thawv los tso saib cov cim npe, cov ntaub ntawv khoom, lossis cov qauv kev tshaj tawm. Deg coatings txhim khu kev ya raws, durability, thiab zoo nkauj txaus siab. Tom qab kev soj ntsuam zoo thiab ntim khoom, cov txheej txheem npaj tiav, kom ntseeg tau tias cov thawv ua tau raws li tus qauv yuav tsum tau ua.
Zuag qhia tag nrho, cardboard lub thawv npaj encompasses cov khoom xaiv, tsim, ua, luam ntawv, thiab tswj kom zoo. Ib txoj kev npaj kev tshawb fawb ua kom muaj kev ua haujlwm thiab kev nyab xeeb, txo cov nqi, nce kev ua haujlwm ntau lawm, thiab ua tau raws li cov kev xav tau sib txawv ntawm kev thauj mus los niaj hnub thiab kev lag luam.
