Yuav Ua Li Cas Zoo Ua Zaub Mov Ntim Boxes Seal?

Cov cim tseem ceeb ntawm lub thawv ntim khoom noj sealing kev ua tau zoo: Sealing kev ua tau zoo cuam tshuam ncaj qha rau cov zaub mov kev nyab xeeb thiab txee lub neej, thiab feem ntau yog ntsuas los ntawm cov ntsuas hauv qab no:

1. Oxygen Transmission Rate (OTR): Lub OTR ntawm siab -cov ntaub ntawv yas zoo tuaj yeem qis dua 5 cm³/m²·24h (xa mus rau GB/T 1038-2000), ua kom cov zaub mov oxidation zoo.

2. Water Vapor Transmission Rate (WVTR): WVTR ntawm aluminium foil composite ntim yog feem ntau<0.1 g/m²·24h (ASTM E96 standard), suitable for high humidity-sensitive foods.

3. Sealing Strength: Lub tev lub zog ntawm cov cua sov- txheej txheem sealing yuav tsum muaj ntau dua los yog sib npaug rau 15 N / 15mm (GB/T 23508-2009) kom tsis txhob tawg thaum lub sij hawm thauj mus los.

Yam tseem ceeb cuam tshuam rau kev ua haujlwm sealing

1. Kev xaiv cov khoom siv:

- Cov yas (xws li PET/PE) yog tus nqi qis- tab sis feem ntau muaj kev sib khi tsis zoo, feem ntau yog siv rau luv luv - cov khoom noj tshiab;

- Aluminium- cov khoom sib xyaw yas muaj cov khoom thaiv zoo heev thiab feem ntau yog siv rau cov khoom siab- kawg xws li mis hmoov thiab kas fes.

2. Txheej Txheem Technology:

- Thaum tshav kub kub sealing kub tswj qhov sib txawv ntawm ± 2℃(cov ntaub ntawv kev lag luam xyaum). Qhov kub thiab txias dhau tuaj yeem ua rau cov khoom deformation, thaum qhov kub thiab txias heev tuaj yeem ua rau kom tawg;

- Nitrogen- ntim ntim tuaj yeem txo qis cov pa oxygen seem kom qis dua 0.5% (saib ISO 14855), ua kom lub neej ntev ntev.

Tej teeb meem thiab kev daws teeb meem hauv kev siv tswv yim

1. Air Leakage: Kwv yees li 3% ntawm cov ntim ntim yog vim muaj kev puas tsuaj rau cov khoom siv los yog kev sib khi ua ke (cov ntaub ntawv los ntawm 2023 qhov teeb meem ntawm *Packaging Engineering* phau ntawv journal), uas tuaj yeem saib xyuas hauv lub sijhawm tiag tiag siv lub tshuab xau online;

2. Temperature Adaptability: Nyob rau hauv tej yam kev mob ntawm -18℃freezing los yog 100℃retorting, tej ntaub ntawv tej zaum yuav muaj kev sealing tsis ua hauj lwm, yuav tsum tau siv cov tshav kub-resistant tshwj xeeb films.
