Dab tsi yog cov khoom siv rau lub hnab ntim khoom?

Lub hnab ntim khoom tuaj yeem tsim los ntawm ntau yam ntaub ntawv, nyob ntawm seb qhov kev xav tau tshwj xeeb ntawm cov khoom ntim thiab cov khoom xav tau ntawm lub ntim. Qee cov ntaub ntawv uas siv rau lub hnab ntim khoom muaj xws li:

Polyethylene (PE): PE yog cov khoom siv dav siv hauv cov yas uas paub txog nws qhov yooj yim thiab ua haujlwm ntev. Nws yog feem ntau siv rau ntim cov kua, hmoov, thiab cov khoom granular.

Polypropylene (PP): PP muaj cov khoom tiv thaiv dej noo zoo heev thiab tiv taus qhov kub thiab txias, ua rau nws haum rau cov ntawv thov kub. Nws yog feem ntau siv rau ntim khoom noj txom ncauj, condiments, thiab lwm yam khoom noj.

Polyester (PET): PET yog cov khoom siv muaj zog thiab hnav nrog cov khoom thaiv zoo tiv thaiv ya raws thiab roj. Nws yog feem ntau siv rau ntim khoom noj thiab dej haus, nrog rau cov khoom tsis yog khoom noj xws li tshuaj thiab cov khoom siv tu tus kheej.

Aluminium Ntawv Nyiaj: Aluminium ntawv ci muab cov khoom thaiv zoo heev tiv thaiv ya raws, lub teeb, oxygen, thiab lwm yam roj. Nws feem ntau yog siv los ua txheej txheej laminate hauv lub hnab ntim khoom los txhim kho lub neej txee ntawm cov khoom xws li khoom noj txom ncauj, kas fes, thiab khoom noj tsiaj.

Nylon (PA): Nylon paub txog nws lub zog thiab puncture tsis kam, ua rau nws tsim nyog rau ntim cov khoom uas yuav tsum tau muaj kev tiv thaiv ntxiv, xws li cov khoom noj khov thiab cov khoom siv lub tshuab nqus tsev.

Ethylene Vinyl Cawv (EVOH): EVOH yog cov khoom siv siab uas muaj kev tiv thaiv zoo heev tiv thaiv cov pa oxygen permeation, txuas lub txee lub neej ntawm cov khoom siv oxygen-rhiab zoo li cov nqaij ua tiav thiab cov khoom siv mis nyuj.

Paperboard: Paperboard hnab yog ib puag ncig tus phooj ywg thiab tuaj yeem coated lossis laminated nrog cov ntaub ntawv zoo li polyethylene los muab cov dej noo thiab roj tsis kam. Lawv feem ntau siv los ntim cov khoom qhuav, khoom noj txom ncauj, thiab dej haus.

Biodegradable thiab Compostable Materials: Nrog rau kev txhawj xeeb ntau ntxiv txog ib puag ncig kev ruaj ntseg, muaj kev xav tau ntau ntxiv rau lub hnab ntim khoom ua los ntawm biodegradable thiab compostable cov ntaub ntawv xws li polylactic acid (PLA), cellulose-based cov ntaub ntawv, thiab bio-based polymers tau los ntawm cov khoom siv txuas ntxiv.
