Thaum tsim cov hnab ntim yas, "nruab nrab txheej", "puab txheej", thiab "txheej txheej" xa mus rau cov txheej txheem sib txawv ntawm lub hnab ntim khoom. Lub hnab ntim cov hnab yas nrog ntau txheej txheej tuaj yeem muab kev ua haujlwm zoo dua thiab cov yam ntxwv kom tau raws li cov kev xav tau sib txawv.
1, Txheej txheej
Muaj nuj nqi: Kev luam ntawv kev ua tau zoo: Cov txheej txheej txheej feem ntau yog siv rau kev luam ntawv, thiab tuaj yeem luam cov logos, cov lus qhia siv, barcodes, thiab lwm yam.
Kev Tiv Thaiv: Cov txheej txheej sab nrauv tiv thaiv lub hnab los ntawm kev cuam tshuam ib puag ncig xws li ya raws, lub teeb, thiab kev puas tsuaj.
Aesthetics: Muab lub ntsej muag du thiab zoo nkauj los txhim kho qhov pom kev pom ntawm lub hnab ntim khoom.
Cov khoom siv: Polyester (PET): muaj kev luam ntawv zoo thiab hnav tsis kam.
Polypropylene (PP): Durable thiab muaj pob tshab zoo.
2, Nruab nrab txheej
Muaj nuj nqi: Barrier kev ua tau zoo: Cov txheej nruab nrab feem ntau muab cov khoom thaiv kev tiv thaiv kom tsis txhob nkag mus ntawm oxygen, noo noo, tsw, thiab lwm yam, thiab txuas ntxiv lub neej txee ntawm cov khoom.
Lub zog: Txhim kho tag nrho lub zog thiab lub zog ntawm lub hnab ntim kom tsis txhob tawg thiab tawg.
Cov khoom siv: Nylon (PA): muaj cov khoom thaiv zoo heev thiab lub zog txhua yam.
Ethylene-vinyl cawv copolymer (EVOH): muaj roj barrier siab heev.
3, Sab hauv txheej
Kev Ua Haujlwm: Sealing kev ua tau zoo: Cov txheej sab hauv yog nyob rau hauv kev sib cuag ncaj qha nrog cov ntsiab lus thiab yuav tsum muaj kev sib khi zoo kom ntseeg tau tias muaj kev nyab xeeb thiab tiv thaiv cov khoom.
Khoom noj khoom haus kev nyab xeeb: Rau kev ntim khoom noj, txheej sab hauv yuav tsum ua kom tau raws li cov qauv kev nyab xeeb ntawm cov khoom noj khoom haus thiab tsis tuaj yeem paug cov zaub mov.
Cov khoom siv: Polyethylene (PE): muaj kev sib khi zoo thiab yoog raws thiab yog cov khoom siv sab hauv feem ntau siv. Linear low-density polyethylene (LLDPE): Txhim kho sealing thiab durability.
Qhov zoo ntawm cov txheej txheem ntau txheej
Kev ua tau zoo: Los ntawm kev sib xyaw ua ke ntawm cov khoom sib txawv, cov hnab yas ntim khoom tuaj yeem muab cov txiaj ntsig zoo ntawm txhua txheej ntawm cov ntaub ntawv, xws li lub zog siab, cov khoom thaiv zoo heev thiab kev luam ntawv zoo.
Tus nqi-zoo: Kev siv cov txheej txheem ntau txheej tuaj yeem ua kom zoo rau kev siv cov khoom siv thiab txo cov nqi thaum tswj kev ua haujlwm.
Kev siv tshwj xeeb: Cov txheej txheem ntau txheej tuaj yeem hloov kho raws li qhov xav tau sib txawv, xws li kev ua haujlwm tshwj xeeb xws li tiv thaiv zoo li qub thiab tiv thaiv UV.
Cov piv txwv ntawm kev siv tswv yim
Khoom noj khoom haus ntim hnab:
Txheej txheej: PET, muab kev luam ntawv zoo thiab hnav tsis kam.
Cov txheej txheem nruab nrab: EVOH, muab cov khoom muaj zog tiv thaiv kom tsis txhob muaj oxygen thiab noo noo nkag mus.
Sab hauv txheej: LLDPE, ua kom cov zaub mov tiv thaiv kev nyab xeeb thiab sealing zoo.
Express ntim hnab
Txheej txheej: PP, muab kev hnav zoo thiab tsis muaj dej.
Nruab nrab txheej: PA, txhim khu lub zog thiab tsim kua muag.
Sab hauv txheej: PE, kom ntseeg tau tias cov ntsiab lus tsis cuam tshuam los ntawm lub ntiaj teb sab nraud thiab muaj kev sib khi zoo.
Los ntawm kev siv cov txheej txheem ntau txheej, cov hnab ntim cov hnab yas tuaj yeem ua tau raws li cov kev xav tau ntawm cov ntawv thov sib txawv thiab muab kev ua tau zoo thiab kev ntseeg siab.
