Cov khoom siv feem ntau siv rau cov hlab ntsha muaj xws li:
Polyethylene (PE): Nrog kev ua haujlwm zoo, kev tiv thaiv corrosion, thiab sealing zog, nws yog ib qho ntawm cov khoom siv feem ntau siv rau cov hlab ntsha. PE cream tubes yog tus pheej yig thiab tsim nyog rau ntim cov khoom qab zib feem ntau, tiv thaiv cov khoom los ntawm kev cuam tshuam sab nraud.
Polypropylene (PP): Nrog cov hardness kuj siab thiab zoo rigidity, nws muaj zoo tshuaj stability thiab kub kuj. PP cov nplaum nplaum yog tsim rau ntim uas yuav tsum tau muaj qee qhov kev tuav pov hwm zoo thiab feem ntau siv rau cov khoom qab zib nrog cov khoom ntim siab.
Polyester (PET): Nrog lub siab pob tshab thiab zoo nkauj zoo nkauj, nws tuaj yeem pom cov xim thiab kev ntxhib los mos ntawm cov khoom qab zib. PET cream raj feem ntau yog siv rau cov khoom uas yuav tsum tau muaj siab rau cov tsos, xws li ib co high - qab zib cream los yog cream nrog tshwj xeeb xim los yog textures.
Aluminium Ntawv Nyiaj: Nrog cov khoom thaiv zoo heev, nws tuaj yeem thaiv cov pa oxygen, noo noo, thiab lub teeb, tiv thaiv cov khoom xyaw nquag hauv cov qab zib los ntawm oxidizing, ua ntub dej, thiab deteriorating. Aluminium ntawv ci feem ntau yog siv los ua ke nrog lwm cov ntaub ntawv yas los tsim cov txhuas- cov yas sib xyaw ua ke, haum rau cov tshuaj nplaum uas muaj cov khoom thaiv tsis zoo, xws li siab - cov qab zib kawg uas muaj cov khoom xyaw oxidized yooj yim.
Ethylene-vinyl cawv copolymer (EVOH): Cov khoom siv ua haujlwm siab - nrog cov khoom thaiv zoo heev tiv thaiv oxygen, noo noo, thiab tshuaj tsw qab. EVOH feem ntau ua ke nrog lwm cov ntaub ntawv yas thiab siv rau hauv ntau- txheej co-extruded qab zib raj, ua kom lub neej ntev ntawm cov khoom thiab tswj qhov zoo thiab ruaj khov ntawm cov khoom xyaw nquag.
Daim ntawv- cov khoom siv yas sib xyaw: Ua los ntawm kev sib txuas cov ntawv ua lub ntsiab substrate nrog ib zaj duab xis yas. Daim ntawv- cov raj yas sib xyaw muaj qee lub zog thiab nruj, thaum lub siab luam ntawv ntawm cov ntawv tso cai rau kev tsim qauv zoo nkauj. Cov khoom siv no sib xyaw ua ke ntawm ib puag ncig kev phooj ywg ntawm daim ntawv nrog cov khoom thaiv ntawm cov yas, ua rau nws tsim nyog rau cov tshuaj nplaum uas hais txog cov ntsiab lus ntuj thiab cov organic.
