Tsis zoo li daim ntawv lo, cov yeeb yaj kiab tshav kub siv tsis yog - nqus cov ntawv luam tawm xws li PVC, PP, PETG, OPS, OPP, thiab ntau yam co-extruded films. Cov khoom ntawm cov ntaub ntawv no txiav txim siab tias lawv cov txheej txheem luam ntawv txawv ntawm cov ntawv sau.
Kev tswj nruj
Vim tias cov yeeb yaj kiab muaj kev cuam tshuam ntau dua rau kev hloov pauv thaum luam ntawv, ua rau kev sau npe tsis raug, nws yog ib qho tseem ceeb uas yuav tsum ua tib zoo tswj kom nruj thiab tswj nws qhov ruaj khov thiab sib npaug thaum luam ntawv.
Xim xaiv
Muaj plaub yam tseem ceeb ntawm inks siv rau shrink film printing: hnyav-raws li inks, dej-raws li inks, cationic UV inks, thiab dawb radical UV inks. Nyob rau hauv cov nqe lus ntawm daim ntawv thov, hnyav-raws li inks dominate nyob rau hauv shrink zaj duab xis daim ntawv lo printing teb, ua raws li dej-raws li inks thiab dawb radical UV inks. Cationic UV inks tsis tshua siv hauv cov yeeb yaj kiab vim lawv cov nqi siab dua thiab cov txheej txheem luam ntawv nyuaj dua. Gravure thiab flexographic heat shrink films feem ntau siv cov kuab tshuaj-raws li inks; cov yeeb yaj kiab sib txawv yuav tsum siv cov inks tshwj xeeb thiab yuav tsum tsis txhob sib xyaw.
Tshuab ziab khaub ncaws
Kev tswj qhov kub kom qhuav yog qhov tseem ceeb thaum luam ntawv thermal shrink zaj duab xis. Yog hais tias qhov ziab kub siab dhau lawm, cov khoom yuav poob vim yog cua sov; Yog tias qhov ntsuas kub qis dhau, tus number case yuav tsis qhuav tag, ua rau adhesion thiab smudging rau sab nraub qaum. Ob lub tshuab luam ntawv gravure thiab flexographic yog nruab nrog inter- xim ziab kom paub meej tias txhua xim number case dries tag nrho.
