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) rakatendera sarudzo yenhoroondo musi wa 2 Kurume 2022 yekugumisa kusvibiswa kwepurasitiki panosvika 2024. Muchikamu chemakambani, semuenzaniso, Coca-Cola's 2025 pasi rose packaging ndeye 100% kudzokororwa, uye Nestlé's 2025 packaging i100. % inogona kushandiswazve kana kushandiswa zvakare.
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 mu polyester recycling tekinoroji, Toray yekuJapan yakazivisa kuvandudzwa kwebio-based naironi N510, uye Suntory Group yeJapan yakazivisa muna Zvita 2021 kuti yakabudirira kugadzira zana remabhodhoro ePET 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 kuvharidzirwa zvakare pazvinhu zvinoshatisa, mutengo wezvokupfekedza zvinhu uye maitirwo achakwidziridzwa, uye kushandiswa kwezvinhu zvinoshatisa mumapakiti akapfava, ayo akapetwa ka2-3 mutengo weiyo yekutanga petrochemical firimu. , zvakaoma.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 kwakapusa kwemhando dzakasiyana-siyana dzemafirimu anosanganisira kudhinda, maficha ekuita uye kupisa chisimbiso, zvinhu zvinowanzo shandiswa ndezvi OPP, PET, ONY, aluminium foil kana aluminized, PE uye PP kupisa sealing zvinhu, PVC uye PETG kupisa kupisa shrinkable mafirimu uye ichangoburwa yakakurumbira MDOPE ine. BOPE.
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 pakuona kwemaitiro ekuchengetedza kwezvakatipoteredza uye hunhu hwezvinhu, mhinduro dzinonyanya kuchengetedzwa kwezvakatipoteredza dzekurongedza dzinochinjika ndeyekugadzira akasiyana ekuchengetedza nharaunda mhinduro kune vakasiyana vatengi uye akasiyana chigadzirwa kurongedza zvinodiwa, pane imwe chete mhinduro, senge imwe chete PE zvinhu. , purasitiki yakasvibiswa kana pepa, iyo inogona kushandiswa kune dzakasiyana-siyana dzekushandisa 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.
