1. Cov Khoom Taw Qhia Cov Khoom: Txhuas ntawv ci (AL) txheej muab cov pa oxygen zoo tshaj thiab cov dej noo thaiv kev ua haujlwm (cov qauv siv xws li PET / NY / AL / PE lossis NY / PE); siab-cov yeeb yaj kiab uas tsis muaj txhuas (xws li EVOH co-extruded films) nyob rau qib thib ob, thaum lub hnab PE txheej txheem muaj kev tiv thaiv tsis muaj zog tshaj plaws.
2. Sealing Mechanism: Cov ntsaws ruaj ruaj ruaj ruaj cia siab rau lub zog foob (feem ntau xav tau ntau dua lossis sib npaug ntawm 7N / 15mm); resealable kaw nyob ntawm seb qhov haum ntawm lub zipper los yog airtightness ntawm lub spout cap, nrog spouted pouches feem ntau muab zoo sealing kev ncaj ncees dua cov qauv zipper hnab.
3. Lub hnab ntim khoom: tiaj tus- hnab hauv qab (xws li yim- sab foob lossis sawv ntsug- cov hnab ntim khoom) muab kev txhawb nqa zoo heev, txo qhov kev pheej hmoo ntawm kev ntxhov siab tawg; conversely, peb -sab lub hnab ntim tau yooj yim rau huab cua to yog tias lub tshav kub- kaw cov npoo yog raug rau siab.
