Kev siv lub tshuab nqus tsev ntim khoom hauv kev lag luam cov khoom siv nqaij

Cov khoom noj nqaij kuj tsim nyog rau lub tshuab nqus tsev ntim khoom. Cov khoom noj nqaij noj feem ntau suav nrog Suav -cov khoom noj nqaij, Western- cov khoom noj nqaij, thiab cov khoom hnyuv ntxwm.

Dhau li ntawm cov kaus poom, Suav -cov khoom noj nqaij feem ntau siv lub tshuab nqus tsev- ntim ntim thiab cua sov- ntsws ntim. Ntau cov khoom lag luam hauv Suav teb yuav tsum tau ua kom muaj qhov kub siab (120 degree) ua kom tsis muaj menyuam tom qab ntim khoom, yuav tsum tau ntim cov khoom ntim uas muaj peev xwm tiv taus kom tsis muaj menyuam ntawm qhov kub siab tshaj 121 degree. Cov khoom siv feem ntau suav nrog PA (PET) / CPP, EVAL / CPP, thiab PA (PET) / A1 ntawv ci / CPP. Cov no feem ntau yog lub tshuab nqus tsev- ntim tom qab siab-kub kom tsis muaj menyuam, ua rau lub neej txee ntev txog 6 lub hlis; cov no feem ntau raug xa mus rau cov khoom ntim cov kaus poom.

Lub ntsiab spoilage mechanisms ntawm Suav qhuav nqaij cov khoom muaj xws li noo noo nqus thiab pwm loj hlob, rog oxidation, thiab tsw hloov. Ntim yuav tsum yog cov pa oxygen- thiab ya raws- pov thawj los tiv thaiv cov teeb meem no. Cov ntaub ntawv tsim nyog suav nrog BOPP / PA (PET) / PE, BOPP / PVA / PE, thiab PT / PE. Txhawm rau tiv thaiv qhov cuam tshuam loj ntawm lub teeb rau cov khoom siv nqaij, ntawv ci-coated PA(BOPP)/PE thiab BOPP/Al/PE feem ntau yog siv, thiab nitrogen- ntim lossis deoxygenated ntim kuj tseem ua tau. Lub tuam txhab Dongguan Guangke lub tshuab nqus tsev ntim khoom tuaj yeem siv rau cov khoom noj nqaij, cov khoom lag luam taum, cov zaub nyoos, thiab lwm yam khoom noj qhuav thiab qis - noo noo.

Rau Western -style ntim cov khoom ntim, qee cov khoom tau kho cua sov ntawm ib ncig ntawm 90℃tom qab sau thiab ntim. To ensure a dense product texture, the packaging material generally requires heat-shrinkable properties, such as PA, PET, and PVDC shrink films. Qee cov khoom lag luam tsis tas yuav tsum tau siab -kub kom tsis muaj menyuam tom qab ua tiav, yog li cov yeeb yaj kiab shrinkage kuj tsim nyog. Qee cov khoom siv tsis tas yuav tsum muaj qhov kub siab - kom tsis muaj menyuam tom qab ua tiav. Lawv tuaj yeem muab ntim rau hauv cov thawv tsis pom kev lossis pob tshab ua los ntawm PE lossis PS cov ntawv los ntawm cov thermoforming, npog nrog ib txheej ntawm pob tshab yas zaj duab xis rau stretch wrapping, los yog tshav kub-shrink ntim nrog PA lossis PVC shrink film. Cov khoom no muaj lub neej luv luv thiab yuav tsum tau muab tso rau hauv tub yees ntawm 4-6 degree.

Cov khoom siv hnyuv ntxwm yog ib hom khoom noj nqaij uas siv cov hnyuv ntxwm ua cov khoom ntim rau kev sau thiab ua kom zoo. Cov khoom tsim, kev tu cev zoo, khaws cia thiab kev faib tawm, thiab kev lag luam tus nqi ntawm cov khoom hnyuv ntxwm yog ncaj qha ntsig txog hom thiab qhov zoo ntawm cov hnyuv ntxwm casings. Txhua hom hnyuv ntxwm casing muaj nws tus kheej cov yam ntxwv. Thaum xaiv cov casings, ib tug yuav tsum xav txog lawv edibility, permeability, shrinkage, sealing, roj thiab dej tsis kam, kub thiab txias kuj, aging kuj, thiab lub zog, raws li cov khoom yuav tsum tau.
