Vim li cas: BOPP thiab VMCPP khawb heev, BOPP muaj peev xwm luam tawm zoo thiab ci ntsa iab. VMCPP muaj cov yam ntxwv zoo thaiv, khaws cov ntxhiab tsw thiab tiv thaiv kom tsis txhob noo noo. Kev tiv thaiv roj CPP kuj zoo dua.
3. Lub hnab ntim khoom qab zib
Cov khoom xav tau: cov khoom thaiv zoo, muaj zog ntxoov ntxoo, tsis kam roj, muaj zog heev, tsis muaj ntxhiab thiab tsis qab, thiab lub ntim khoom khawb heev.
Qauv tsim: BOPP/EXPE/VMPET/EXPE/S-CPP
Vim li cas: BOPP muaj kev ruaj khov zoo, luam tawm tau zoo thiab pheej yig. VMPET muaj cov yam ntxwv zoo thaiv, zam lub teeb, oxygen, thiab dej. S-CPP muaj kev sib khi zoo thaum kub thiab tsis kub thiab tiv taus roj.
4. Cov hnab ntim hmoov mis nyuj
Cov khoom xav tau: lub neej ntev txee, tsw qab thiab saj, tiv thaiv kev puas tsuaj los ntawm oxidative, tiv thaiv kev ua kom noo noo.
Qauv tsim: BOPP/VMPET/S-PE
Vim li cas: BOPP muaj peev xwm luam tawm zoo, ci ntsa iab zoo, muaj zog zoo thiab tus nqi nruab nrab.
VMPET muaj cov khoom thaiv zoo, zam lub teeb, muaj zog zoo, thiab muaj lub teeb ci ntsa iab. Nws zoo dua los siv cov hlau PET uas muaj zog, thiab txheej AL tuab. S-PE muaj kev sib khi zoo tiv thaiv kev ua qias tuaj thiab kev sib khi kub qis.
5. Cov hnab tshuaj yej ntsuab
Cov khoom xav tau: tiv thaiv kev puas tsuaj, tiv thaiv kev hloov xim, tiv thaiv ntxhiab tsw, uas yog, tiv thaiv kev oxidation ntawm cov protein, chlorophyll, catechin, thiab vitamin C uas muaj nyob hauv tshuaj yej ntsuab.
Cov qauv tsim: BOPP / AL / PE, BOPP / VMPET / PE, KPET / PE
Vim li cas: AL ntawv ci, VMPET, KPET yog cov ntaub ntawv uas muaj cov yam ntxwv zoo heev, thiab lawv muaj cov yam ntxwv zoo tiv thaiv cov pa oxygen, cov dej ua pa thiab cov ntxhiab tsw. AK ntawv ci thiab VMPET kuj muaj cov yam ntxwv zoo heev tiv thaiv lub teeb. Tus nqi ntawm cov khoom yog nruab nrab.
6. Cov hnab kas fes av
Cov khoom xav tau: Tiv thaiv kev nqus dej, tiv thaiv kev oxidation, tiv taus cov pob tawv ntawm cov khoom tom qab nqus tsev, thiab khaws cov ntxhiab tsw ntawm kas fes uas yooj yim oxidized.
Cov qauv tsim: PET / PE / AL / PE, PA / VMPET / PE
Vim li cas: AL, PA, VMPET muaj cov khoom thaiv zoo, dej thiab roj thaiv cov khoom, thiab PE muaj cov khoom kaw cua sov zoo.
7. Cov hnab ntim khoom qab zib
Cov khoom xav tau: cov khoom thaiv zoo, zam lub teeb, luam ntawv zoo nkauj, kub qis sealing.
Cov qauv tsim: cov xim pleev xim chocolate ntshiab / kua mem / dawb BOPP / PVDC / cov khoom siv sealant txias
Xim av Varnish/Ink/VMPET/AD/BOPP/PVDC/Cold Sealant
Vim li cas: PVDC thiab VMPET yog cov khoom siv thaiv siab. Cov kua nplaum txias tuaj yeem kaw tau ntawm qhov kub qis heev, thiab qhov kub yuav tsis cuam tshuam rau cov chocolate. Vim tias cov txiv ntoo muaj roj ntau dua thiab yooj yim rau kev puas tsuaj oxidative, ib txheej oxygen barrier ntxiv rau hauv cov qauv.
