Environmental Policy uye Dhizaini Mazano
Mumakore achangopfuura, kuchinja kwemamiriro ekunze uye kusvibiswa kwakasiyana-siyana kwave kuchishumwa nguva dzose, zvichikwezva nyika dzakawanda nemabhizinesi, uye nyika dzakaronga mitemo yekuchengetedzwa kwemhoteredzo imwe pashure peimwe.
Sangano reUnited Nations Environment Assembly (UNEA-5) rakabvumira chisarudzo chenhoroondo musi wa 2 Kurume 2022 kupedza kusvibiswa kwepurasitiki panosvika 2024. Muchikamu chemakambani, semuenzaniso, Coca-Cola's 2025 global packaging is 100% recyclable, uye Nestlé's 2025 packaging inogona kushandiswa zvakare ne10%.
Uye zvakare, masangano epasi rese, akadai seanochinjika kurongedza denderedzwa hupfumi CEFLEX uye yevatengi zvinhu theory CGF, zvakare anoisa kumberi denderedzwa hupfumi dhizaini misimboti uye goridhe dhizaini misimboti zvichiteerana. Aya maviri magadzirirwo emisimboti ane madhairekitori akafanana mukuchengetedzwa kwezvakatipoteredza kweanochinjika kurongedza: 1) Single zvinhu uye yese-polyolefin iri muchikamu chezvezvekushandisa; 2) Hapana PET, nylon, PVC uye zvinhu zvinosvibisa zvinobvumirwa; 3) Barrier layer coating Iyo tier haigone kudarika 5% yese.
Tekinoroji inotsigira sei zvakatipoteredza flexible packaging
Tichifunga nezve kuchengetedzwa kwezvakatipoteredza marongero akapihwa kumba nekune dzimwe nyika, nzira yekutsigira kuchengetedzwa kwezvakatipoteredza kwekuchinjika kurongedza?
Chekutanga pane zvese, mukuwedzera kune zvinoshatisa zvinhu uye matekinoroji, vagadziri vekunze vakaisa mari mukusimudziramapurasitiki ekudzokorodza uye bio-based mapurasitiki uye zvigadzirwa. Semuyenzaniso, Eastman wekuUnited States akadyara mari mupolyester recycling tekinoroji, Toray yekuJapan yakazivisa kuvandudzwa kwebio-based naironi N510, uye Suntory Group yeJapan yakazivisa muna Zvita 2021 kuti yakabudirira kugadzira zana muzana bio-based PET bhodhoro prototype.
Chechipiri, mukupindura mutemo wepamba wekurambidza kushandiswa-kamwe mapurasitiki, kuwedzera kunezvinoshatisa zvinhu PLA, China yakaisawo marimukugadzirwa kwezvinhu zvakasiyana-siyana zvinoparara zvakaita sePBAT, PBS nezvimwe zvinhu uye zvine chekuita nazvo. Zvimiro zvemuviri zvezvinhu zvinoshatisa zvinogona kusangana ne-akawanda-inoshanda zvinodiwa zvekuchinjika kurongedza?
Kubva pakuenzaniswa kwezvinhu zvemuviri pakati petrochemical films nemafirimu anoshatisa,zvipingamupinyi zvezvinhu zvinoparara zvichiri kure nemafirimu echinyakare. Pamusoro pezvo, kunyangwe zvipingamupinyi zvakasiyana-siyana zvinogona kuvezwa zvakare pazvinhu zvinoshatisa, mutengo wezvokupfekedza zvinhu uye maitirwo achakwidziridzwa, uye kushandiswa kwezvinhu zvinoshatisa mumapakiti akapfava, ayo akapetwa ka2-3 mutengo weiyo yekutanga petrochemical firimu, zvakanyanya kuoma.Naizvozvo, kushandiswa kwezvinhu zvinoshatisa mukutakura kuchinjika kunodawo kuisa mari mukutsvagisa nekuvandudza kwezvinhu zvakagadziriswa kugadzirisa matambudziko ezvivakwa zvemuviri uye mutengo.
Flexible packaging ine musanganiswa wakaomarara wezvinhu zvakasiyana siyana kusangana nezvinodiwa zvechigadzirwa pakuonekwa kwese uye kushanda kwepakeji. Kurongeka kwakapfava kwemhando dzakasiyana-siyana dzemafirimu anosanganisira kudhinda, mashandiro anoita uye kupisa chisimbiso, zvinhu zvinowanzo shandiswa ndezveOPP, PET, ONY, aruminiyamu foil kana aluminized, PE uye PP kupisa sealing materials, PVC nePETG heat shrinkable films uye ichangoburwa yakakurumbira MDOPE neBOPE.
Nekudaro, kubva pamaonero ehupfumi hwedenderedzwa hwekudzokorodza uye kushandisazve, misimboti yekugadzira yeCEFLEX neCGF yehupfumi hwedenderedzwa hwekurongedza inochinjika inoita senge imwe yenzira yekuchengetedzwa kwezvakatipoteredza chirongwa chekurongedza chinochinjika.
Chekutanga pane zvese, akawanda anochinjika ekurongedza zvinhu PP imwe chete zvinhu, sepakarepo noodle packaging BOPP/MCPP, uyu musanganiswa wezvinhu unogona kusangana nechinhu chimwe chete chehupfumi hwedenderedzwa.
Chechipiri,pasi pemamiriro emabhenefiti ehupfumi, chirongwa chekuchengetedza kwezvakatipoteredza chekurongedza chinochinjika chinogona kuitwa munzira yekurongedza chimiro chechinhu chimwe chete (PP & PE) isina PET, de-nylon kana ese polyolefin zvinhu. Kana bio-yakavakirwa zvinhu kana zvakatipoteredza zvine hushamwari zvakakwirira-zvipingamupinyi zvinhu zvakajairika, petrochemical zvinhu uye aruminiyamu foil zvinozotsiviwa zvishoma nezvishoma kuti zviwane zvakatipoteredza zvakapfava pasuru chimiro.
Chekupedzisira, kubva pamaonero emaitiro ekuchengetedza kwezvakatipoteredza uye hunhu hwezvinhu, mhinduro dzinonyanya kuchengetedzwa kwezvakatipoteredza dzekurongedza dzinochinjika ndedzekugadzira mhinduro dzakasiyana dzekuchengetedza nharaunda kune vatengi vakasiyana uye zvakasiyana zvigadzirwa zvekurongedza zvinodiwa, pane imwe chete mhinduro, senge imwe chete PE zvinhu, inoparara purasitiki kana bepa, iyo inogona kuiswa kune akasiyana mashandisiro mamiriro. Naizvozvo, zvinokurudzirwa kuti pachinzvimbo chekusangana nezvinodiwa zvekurongedza zvigadzirwa, zvinhu uye chimiro zvinofanirwa kugadziridzwa zvishoma nezvishoma kune yazvino chirongwa chekuchengetedza kwezvakatipoteredza icho chinonyanya kudhura. Kana iyo yekudzokorodza sisitimu yakanyanya kukwana, kudzokorodza uye kushandiswazve kweanochinjika kurongedza inyaya yechokwadi.
