Tsab xov xwm no tshawb nrhiav vim li cas PE sawv tawm ua "tus neeg saib xyuas kev nyab xeeb" hauv kev khaws cia zaub mov thiab nws cov txiaj ntsig zoo tshaj plaws.
Cov Khoom Siv PE Zoo: Kev Nyab Xeeb thiab Kev Ua Haujlwm Ua Ke
1.Tsis Muaj Tshuaj Lom & Muaj Daim Ntawv Pov Thawj Qib Khoom Noj
PE (polyethylene) yog tib lub yas siv dav dav uas tau ntawv pov thawj los ntawmFDA rau kev sib cuag zaub movNws cov qauv molecular ruaj khov ua kom nws tsis muaj cov yas, BPA, lossis lwm yam tshuaj lom neeg. Txawm hais tias khaws cov khoom noj menyuam yaus lossis rov ua kom cov kua zaub sov, cov hnab PE tsis tso tawm cov tshuaj lom, lav kev nyab xeeb los ntawm kev tsim khoom mus rau kev siv txhua hnub.
2.Kev Siv Tshuab Sealing Triple-Layer
Cov hnab PE ziplock muaj lub zipper swb patented thiab cov qauv kaw rautiv thaiv cua tsis nkag, tiv thaiv dej thiab tiv thaiv kab mob:
- Thaiv cov pa oxygen kom qeeb qeeb oxidation (piv txwv li, tiv thaiv cov txiv hmab txiv ntoo kom xim av).
- Tiv taus cov dej noo kom cov khoom qhuav huv si.
- Cov npoo kaw ob zaug tiv thaiv kev sib kis kab mob hauv lub tub yees.
3.Kev Tiv Thaiv Kub Hnyav (-40 ° C txog 110 ° C)
PE qhov kev ywj pheej ua kom ntseeg tau tias muaj kev ntseeg siab hauv cov xwm txheej hnyav:
- Siv tau rau hauv lub tub yees khov: Tiv taus qhov tawg txawm tias nyob rau -40°C, khaws cov nqaij tau txog li 3 lub hlis.
- Tiv taus kubSiv tau rau hauv lub tshuab hluav taws xob microwave (zog tsawg/nruab nrab) los yog siv ua txheej tiv dej rau kev ua noj sous-vide.
Kev Sib Piv Khoom Siv: Vim Li Cas PE Ua Tau Zoo Dua Lwm Txoj Hauv Kev
| Khoom siv | Kev Nyab Xeeb | Tus nqi | Cov Ntaub Ntawv Siv Zoo Tshaj Plaws |
|---|---|---|---|
| PE | Tsis muaj tshuaj lom, siv tau dua | $0.04-0.07/lub hnab | Kev khaws cia txhua hnub, kev khov, kev mus ncig |
| PVC | Ua los ntawm chlorine, muaj kev pheej hmoo | $0.03-0.06/lub hnab | Kev lag luam (tsis yog khoom noj) |
| Silicone | Muaj kev nyab xeeb tab sis yooj yim stains | $0.70-1.10/lub hnab | Ua noj kub heev, siv dua |
Lus Cim: PVC raug txwv hauv EU rau kev ntim khoom noj vim muaj peev xwm tso tawm cov dioxin.
