Lub hauv paus ntsiab lus ntawm khov- sealing coated paper: Coated paper yog cov khoom sib xyaw ua los ntawm laminating ib txheej ntawm polyethylene (PE) los yog polypropylene (PP) yas rau saum npoo ntawm daim ntawv zoo tib yam. Nws qhov kev ua tau zoo sealing feem ntau yog nyob ntawm cov khoom ntawm cov yas txheej. Thaum kub poob mus rau -18 degree:
PE txheej khaws cia nws yooj yim thiab zoo thaiv cov dej noo.
Daim ntawv hauv paus tuaj yeem ua nkig ntawm qhov kub thiab txias, tab sis cov txheej yas tuav nws lub foob.
Nws raug nquahu kom xaiv cov txheej txheej nrog lub thickness ntawm Ntau dua lossis sib npaug ntawm 30μm rau lub foob zoo dua.
Peb qhov tsim nyog khov scenarios:
Short-lub sij hawm khov: Rau ua ntej- npaj cov tais diav thiab pastries khaws cia rau 1-3 lub hlis, lub hnab ntawv coated tuaj yeem kaw ncaj qha.
Kev tiv thaiv rov ntim dua: Tsim nyog rau rov ntim cov nqaij nruab deg khov thiab cov nqaij thaum siv nrog tus kheej - cov hlua khi.
Kev ntim khoom thib ob: Raws li cov dej noo- cov ntaub ntawv pov thawj rau cov dej khov thiab cov khoom qab zib khov.
Kev ceev faj rau kev siv:
Cov ntsiab lus no cuam tshuam qhov tseeb sealing nyhuv:
Tsis txhob rov thawing: Condensation tuaj yeem nkag mus rau ntawm daim ntawv fiber ntau.
Qhuav qhov chaw ua ntej sealing: Cov dej tee dej khov yuav ua rau lub foob kev ncaj ncees.
Tsis haum rau khaws cov khoom noj ntse: Cov pob txha khov tuaj yeem ua rau cov txheej txheej txheej.
Ntev- lus pom zoo cia: Rau kev khaws cia tshaj 6 lub hlis, hloov mus rau lub ntim yas ntshiab.
