Pamene malamulo a chilengedwe akuchulukirachulukira komanso kuzindikira kwa ogula kukuchulukirachulukira, makanema owonongeka akukula kwambiri ngati njira yokhazikika yosinthira mapulasitiki achikhalidwe. Komabe, mafunso okhudza momwe amagwirira ntchito, kutsata, komanso kutsika mtengo amakhalabe ofala. FAQ iyi imayankha mafunso khumi omwe amafunsidwa kawirikawiri kuchokera kwa akatswiri odziwa ntchito, kupereka kumveka bwino pa sayansi ya zinthu, kuchuluka kwa ntchito, ndi momwe msika ukuyendera. Tikhudzanso cellophane - filimu yachilengedwe, yosawonongeka yomwe ikubweranso m'mapaketi ozindikira zachilengedwe.
Kodi mafilimu opangidwa ndi biodegradable ndi chiyani ndipo amawononga bwanji?
Mafilimu a biodegradablendi zinthu zomwe zingathe kuphwanyidwa ndi tizilombo toyambitsa matenda kukhala madzi, carbon dioxide, ndi biomass. Mosiyana ndi mapulasitiki achikhalidwe, omwe amakhalapo kwa zaka mazana ambiri, zinthuzi zimawonongeka mwachilengedwe pamikhalidwe yapadera.
Ndikofunikira kusiyanitsa pakati pa "biodegradable" - kuwonongeka pansi pa zochitika zazing'ono - ndi "compostable," zomwe zimafuna malo olamulidwa (mwachitsanzo, kompositi ya mafakitale) kuti ziwonongeke mkati mwa nthawi yodziwika popanda kusiya zotsalira zapoizoni.
Ndi zinthu ziti zomwe zimagwiritsidwa ntchito m'mafilimu osawonongeka ndipo zimasiyana bwanji?
Polylactic Acid (PLA)
Chochokera ku chimanga kapena nzimbe,Chithunzi cha PLAimapereka kumveka bwino komanso kusasunthika koma ndi brittle, mongaKanema wa PLA wopangira chakudya, ndipo sizoyenera kugwiritsa ntchito mawonekedwe apamwamba. Manyowa a kompositi amafunikira kuti awonongeke.
Mafilimu a Cellophane
Wopangidwa kuchokera ku cellulose wosinthika (nthawi zambiri zamkati zamatabwa),filimu ya cellophanendi zowonekera, zopumira, ndipo zimatha kuwonongeka m'mafakitale ndi chilengedwe chonse. Ndi njira yabwino kwambiri yopangira zakudya zomwe zimafunikira kuwongolera chinyezi. Ngakhale ndi eco-friendlyliness, ili ndi ndalama zambiri zopangira komanso kutentha kochepa.
Kodi mafilimuwa amanyozeka pamikhalidwe yotani, ndipo zimatenga nthawi yayitali bwanji?
Makanema omwe amawonongeka pang'onopang'ono amawonongeka mosiyanasiyana malinga ndi momwe zinthu zilili komanso chilengedwe monga kutentha, chinyezi, ndi zochitika za tizilombo.
Polylactic Acid (PLA)
Mafilimu a PLAzimafuna mikhalidwe ya kompositi ya mafakitale (pafupifupi 60 °C, chinyezi chambiri) kuti iwonongeke mkati mwa miyezi 3-6. M'nthaka yachilengedwe kapena kompositi yakunyumba, kuwonongeka kumakhala pang'onopang'ono.
Cellophane
Mafilimu a Cellophane, opangidwa kuchokera ku cellulose wopangidwanso, amawonongeka m'masiku 30-60 pansi pamikhalidwe ya kompositi yapanyumba kapena mafakitale. Makanema okutidwa a cellophane atha kutenga masiku 120 chifukwa chowonjezera chithandizo chapamwamba.
Langizo: Nthawi zonse fufuzani ziphaso ngatiEN 13432 or Chithunzi cha ASTM D6400, zomwe zimatsimikizira ngati chinthucho chili ndi compostable pamikhalidwe inayake.
Kodi mafilimu owonongeka ndi biodegradable amafanana bwanji ndi mapulasitiki akale pamtengo wake?
Makanema osawonongeka nthawi zambiri amakhala okwera mtengo kuposa mapulasitiki wamba ngati LDPE kapena PET. Komabe, mtengo wawo wautali umakhala mu:
Ubwino wamalamulo ndi msonkho
M'magawo ambiri, makampani omwe amagwiritsa ntchito zonyamula zokhazikika amatha kupindula ndi zolimbikitsa zamisonkho kapena kupewa chindapusa chokhudzana ndi kuletsa kwapulasitiki.
Mtengo Wonse wa Mwini (TCO)
Kuchepetsa mtengo woyeretsa chilengedwe, kutayidwa kosavuta, komanso kuwongolera mawonekedwe amtundu nthawi zambiri kumathetsa mtengo wokwera wamtsogolo.
Zokonda za ogula
Makasitomala ozindikira zachilengedwe amakhala ndi mwayi wosankha mitundu yomwe imawonetsa mayendedwe okhazikika kudzera m'mapaketi omwe amatha kuwonongeka.
M'kupita kwa nthawi, pamene masikelo opanga ndi matekinoloje akukula, mtengo wamakanema owonongeka akuyembekezeka kutsika.
Kodi mafilimu omwe amawonongeka ndi chiyani?
Mafilimu opangidwa ndi biodegradable ali ndi ntchito zosiyanasiyana m'magawo osiyanasiyana. Kutengera magawo azogulitsa a YITO, amagwiritsidwa ntchito makamaka mu:
Kupaka Chakudya
-
Mafilimu ang'onoang'ono a PLA, PLA zipatso & masamba matumba-Kwakulongedza zipatso ndi ndiwo zamasamba, yopereka kuwonekera bwino komanso kuwongolera chinyezi.
-
Mafilimu a PLA, mafilimu apamwamba kwambiri a PLA- Zoyenera kuphikidwa, zokhwasula-khwasula, zokometsera, ndi zolemba zamabotolo chifukwa cha kusindikizidwa, kumveka bwino, komanso zotchingira mpweya.
Mafilimu Azaulimi
-
Mafilimu a PLA- Makanema osawonongeka omwe amagwiritsidwa ntchito kuphimba nthaka, kukonza kutentha ndi kusunga chinyezi. Iwo mwachibadwa amawonongeka pambuyo pozungulira mbewu, kuchepetsa ntchito yochotsa.
Logistics ndi Industrial Packaging:
-
Mafilimu a PLAndiZithunzi za PLA- Perekani zonyamula zotetezeka zoyendera ndi zosungiramo zinthu, zokhala ndi mphamvu zolimba komanso kusinthasintha.
Zogulitsa Zogulitsa, Mphatso, ndi Zolemba:
-
Mafilimu a Cellophanendi mafilimu a PLA amagwiritsidwa ntchito kwambiri pomanga mphatso, moni manja manja khadi, ndi kulongedza ndudu, mongakukulunga kwa cigar cellophane. Mapeto awo onyezimira komanso kupuma kwawo kumawapangitsa kukhala abwino powonetsera zinthu zapamwamba kwambiri.
Ntchito iliyonse imagwirizana ndi zosowa za eco-packaging ndipo imakondedwa kwambiri ngati njira yokhazikika yosinthira mapulasitiki opangidwa ndi petroleum.
Ndi njira ziti zabwino zosungira ndi kutumiza makanema owonongeka?
Kusungidwa koyenera ndi zoyendera ndizofunikira kuti tisunge mawonekedwe ndi magwiridwe antchito amafilimu owonongeka:
Kuwongolera zachilengedwe:
Sungani pamalo ochepera 30 ° C ndi chinyezi chochepera 60%. Kutentha ndi chinyezi kungayambitse kuwonongeka koyambirira kapena kusokoneza makina.
Kutsata moyo wa alumali
Lembetsani momveka bwino tsiku lopanga ndikulimbikitsidwa kugwiritsa ntchito nthawi (nthawi zambiri miyezi 6-12), makamaka makanema omwe amagwiritsidwa ntchito polumikizana ndi chakudya kapena kusindikiza.
Zodzitchinjiriza:
Gwiritsani ntchito zolembera zamkati zomwe sizingawononge chinyezi (monga zikwama za zojambulazo) ndipo lembani momveka bwino ndi malangizo ogwirira ntchito kuti mupewe kuwonongeka panthawi yaulendo.
Kutenga njira zodzitetezera kumawonetsetsa kuti mafilimu azichita momwe amafunira akafika kwa kasitomala.
Kodi mawonekedwe ndi kusasinthasintha kwa mafilimu omwe angawonongeke angatsimikizidwe bwanji?
Kusunga machitidwe apamwamba komanso osasinthasintha m'mafilimu osawonongeka kumaphatikizapo njira zingapo zabwino:
Zodzitchinjiriza:
Sankhani opanga ovomerezekaISO 9001ndi kutsatira miyezo yoyenera mongaEN 13432, Chithunzi cha ASTM D6400, kapenaBPI.
Kuyesa kwathunthu
-
Kuthamanga kwamphamvu ndi kutalika panthawi yopuma (ASTM D882 / ISO 527)
-
Kukana kubowola (ASTM F1306)
-
Mpweya wamadzi ndi mitengo yotumizira mpweya (MVTR/OTR)

Kusindikiza kutentha, kuwonekera, ndi malipoti a biodegradation
Macheke osasinthasintha
Fananizani zitsanzo zamagulu amitundu, magwiridwe antchito, ndi kutsika kwamtundu motsutsana ndi zomwe zanenedwa.
Kutsimikizika kwa chipani chachitatu
Phatikizani ma labu kuti muyesere pawokha ngati compostability kapena makina amagwirira ntchito ngati pakufunika.
Kuyesa kwa ntchito m'munda
Chitani zoyeserera pakuyika pamizere yeniyeni yodzaza/kusindikiza kuti mutsimikizire kuti zikugwirizana ndi zomwe zikuchitika mdziko lenileni.
Kodi tsogolo la mafilimu owonongeka ndi chiyani?
Kuyesa kwa ntchito m'munda
-
Zida za m'badwo wotsatiramonga PHA (polyhydroxyalkanoates), zomwe zimatha kuwonongeka m'madzi.
-
Njira zopangira compostable kunyumbazomwe zimagwira ntchito m'malo otsika kwambiri, opanda chinyezi.
-
Tekinoloje yowonjezereka yotchingapogwiritsa ntchito zokutira zowola kapena zowonjezera za nano.
-
Kulimbikitsa ku zinyalala zaulimi(mwachitsanzo, bagasse, udzu wa m'nyanja) kuti muchepetse mpikisano wa mbewu.
Pamene ndondomeko monga EU Green Deal ndi ziletso zapulasitiki zapadziko lonse zikulimba, kufunikira kwa mafilimu owonongeka ndi zatsopano zidzapitirira kukula, makamaka pa malonda a e-commerce, katundu wamtengo wapatali, ndi magawo a FMCG omwe amaganizira zachilengedwe.
