1. Cov khoom siv
Pob tshab polyethylene hnab yog tsim los ntawm ob hom polyethylene cov ntaub ntawv: low-density polyethylene (LDPE) thiab high-density polyethylene (HDPE).
Tsawg-density polyethylene (LDPE): Cov khoom siv LDPE muaj qhov pom tseeb thiab yooj yim, thiab feem ntau yog siv los ua cov hnab ntim khoom noj, hnab ziplock, lub hnab ntim lub freezer, thiab lwm yam. Cov khoom no zoo nkaus li mos thiab muaj zog stretchability, uas yog haum rau ntim khoom uas yuav tsum tau. qhib thiab kaw ntau zaus, xws li cov hnab ntim khoom noj.
High-density polyethylene (HDPE): HDPE cov khoom yog tawv thiab hnav-resistant, nrog me ntsis qis pob tshab, tab sis muaj zog dua thiab puncture kuj, thiab feem ntau yog siv los ua lub hnab khw, hnab khib nyiab, thiab lwm yam. Cov khoom no yog tsim rau ntim. uas yuav tsum tau ntau dua durability thiab load-bearing muaj peev xwm.
2. Hom thiab daim ntawv thov
Hom pob tshab polyethylene hnab yog nplua nuj thiab ntau yam, npog cov kev xav tau ntawm yuav luag txhua qhov chaw ntawm lub neej:
Lub hnab ntim khoom: hnab yas feem ntau siv hauv cov khw muag khoom loj thiab cov khw muag khoom, feem ntau yog ua los ntawm cov ntaub ntawv HDPE, nrog lub peev xwm thauj khoom siab.
Cov hnab ntim khoom noj: suav nrog cov hnab ntim khoom noj zoo tib yam, lub hnab nqus tsev thiab lub hnab ntim khoom noj, siv los tiv thaiv cov khoom noj kom zoo thiab tshiab. Lub pob tshab tsim ua rau cov ntsiab lus meej meej ntawm ib nrais muag, uas yooj yim rau cov neeg siv khoom txheeb xyuas.
Lub hnab Ziplock: tseem hu ua lub hnab ntim khoom, feem ntau yog siv los khaws cov khoom me me, khoom noj txom ncauj, tshuaj, thiab lwm yam. Lub hnab ntim lub qhov ncauj muaj lub hnab ntim tus kheej, uas yooj yim rau ntau qhov qhib thiab kaw kom cov khoom qhuav thiab huv si.
Cov hnab khib nyiab: siv los khaws cov khib nyiab hauv tsev, chaw ua haujlwm thiab chaw pej xeem. Lub pob tshab tsim ua kom yooj yim rau kev faib tawm thiab saib cov ntsiab lus, tshwj xeeb tshaj yog tsim rau cov khib nyiab rov ua dua tshiab uas yuav tsum tau txheeb xyuas.
Cov hnab ntim khoom lag luam: siv rau kev ntim khoom thiab kev thauj mus los ntawm cov khoom lag luam, xws li cov khoom siv, cov cuab yeej kho vajtse, thiab lwm yam. Cov hnab ntim polyethylene tuaj yeem tiv thaiv plua plav thiab ya raws, thiab tuaj yeem tiv thaiv cov khoom tsis zoo.
3. Qhov zoo
Pob tshab polyethylene hnab muaj ntau qhov zoo vim lawv cov khoom siv tshwj xeeb thiab ntau yam:
High transparency: Nws yog ib qho yooj yim mus saib cov ntsiab lus ntawm lub hnab, tshwj xeeb tshaj yog haum rau cov zaub mov ntim thiab cov khoom tso saib.
Moisture-proof thiab waterproof: Polyethylene cov ntaub ntawv nws tus kheej muaj cov khoom zoo waterproof, haum rau ntim cov khoom uas yuav tsum tau ya raws.
Kev yooj yim zoo: Lub hnab tuaj yeem tiv taus qee yam ntawm lub zog tensile, tsis yooj yim tawg, thiab haum rau ntau yam kev siv.
Lub teeb yuag: Lub teeb yuag, yooj yim nqa thiab siv, thaum txo nqi tsheb thauj mus los.
Recyclable: Feem ntau cov hnab polyethylene yog recyclable, ua tau raws li kev tiv thaiv ib puag ncig thiab txo cov pa phem.
4. Kev tiv thaiv ib puag ncig thiab kev txhim kho yav tom ntej
Nrog rau kev txhim kho thev naus laus zis, ntau thiab ntau lub hnab polyethylene tau pib siv cov khoom siv degradable thiab recyclable. Piv txwv li, qee lub hnab yog ua los ntawm cov yas rov ua dua tshiab, txo qhov kev thov rau cov yas tshiab thiab cov pa roj carbon hneev taw ntawm cov txheej txheem tsim khoom. Degradable polyethylene hnab kuj tau tsim uas tuaj yeem decompose nyob rau hauv ib puag ncig ntuj, ntxiv txo qhov cuam tshuam rau ib puag ncig.
Pob tshab polyethylene hnab yuav txuas ntxiv innovate nyob rau hauv cov qauv ntawm kev txhim kho kom ruaj khov thiab ntsuab ib puag ncig tiv thaiv, thiab txhim kho nyob rau hauv ib tug ntau tus phooj ywg environmentally thiab multifunctional kev taw qhia. Los ntawm kev txhim kho cov txheej txheem tsim khoom, txhim kho cov khoom ua tau zoo thiab kev ua kom zoo dua qub, cov hnab polyethylene pob tshab yuav txo lub nra ntawm ib puag ncig thaum tswj lawv cov yam ntxwv zoo dua.
