Njengoko intshukumo yehlabathi ejolise kuzinzo ikhula ngamandla, abathengi abaninzi kunye namashishini aguqukela kwizisombululo zokupakishwa kwe-biodegradable. Phakathi kwazo, iifilimu ezingonakaliswayo zikhuthazwa ngokubanzi njengezinye iindlela eco-friendly kwiiplastiki eziqhelekileyo. Kodwa nantsi ingxaki: ayizizo zonke iifilim ezinokuguquguquka ngokwenyani - kwaye umahluko ungaphezulu nje kwesemantics. Ukuqonda into eyenza ifilimuivundisiwe ngokweneneKubalulekile ukuba ukhathalele iplanethi kunye nokuthotyelwa.
Ke, unokwazi njani ukuba ifilimu yakho yokupakisha iya kubuyela ngokungenabungozi kwindalo okanye ihlale kwindawo yokulahla inkunkuma? Impendulo ilele kwizatifikethi.
I-Biodegradable vs. Compostable: ngowuphi owona mahluko?
Ifilimu enokubola
Ifilimu enokubolas, njengaIfilimu ye-PLA, zenziwe ngezinto ezinokwahlulwa zizinto ezincinane ezifana neebhaktheriya okanye umngundo. Nangona kunjalo, le nkqubo inokuthatha iminyaka kwaye inokufuna iimeko ezithile zokusingqongileyo ezifana nobushushu, ukufuma, okanye ioksijini. Okubi nakakhulu, ezinye iifilimu ezibizwa ngokuba yi-biodegradable films ziyancipha zibe yi-microplastics - kungekhona ncam eco-friendly.
Ifilimu eCompostable
Iifilimu ezivundisiweyo zihamba phambili. Azithobi nje kuphela kwi-biodegrade kodwa kufuneka zikwenze oko phantsi kweemeko zokwenziwa komgquba ngexesha elibekiweyo, ngokwesiqhelo iintsuku ezingama-90 ukuya kwezili-180. Okubaluleke ngakumbi, kufuneka bahambeakukho ntsalela enetyhefukwaye zivelise kuphela amanzi, ikharbon diokside, kunye ne-biomass.
Kukho iindidi ezimbini eziphambili:
-
Iifilimu ezivundisiweyo kwimizi-mveliso: Funa ukushisa okuphezulu, indawo elawulwayo.
-
Iifilimu ezivundisiweyo zasekhaya: Yaphula kwimigqomo ye-compost engasemva kwendlu kumaqondo obushushu asezantsi, njengawoifilimu ye-celllophane.
Kutheni iziqinisekiso zibalulekile?
Nabani na unokuqhwaba “eco-friendly” okanye “biodegradable” kwileyibhile yemveliso. Yiyo loo nto umntu wesithathuiziqinisekiso zokuvundisazibaluleke kakhulu - ziyaqinisekisa ukuba imveliso ihlangabezana nemigangatho engqongqo yokhuseleko lokusingqongileyo nokusebenza.
Ngaphandle kwesiqinisekiso, akukho siqinisekiso sokuba ifilimu iya kuvundisa njengoko bekuthembisiwe. Okona kubi, iimveliso ezingaqinisekiswanga zingonakalisa iindawo zomgquba okanye zilahlekise abathengi be-eco-conscious.
Izatifikethi eziThenjiweyo zokuThobeka kwiHlabathi liphela

Ingcamango yokuGqibela: Isiqinisekiso asiyonto iKhethekileyo — sibalulekile
Kungakhathaliseki ukuba ifilimu inokuba yi-biodegradable kangakanani, ngaphandle kweisatifikethi esifanelekileyo, kukuthengisa nje. Ukuba uluhlobo lokupakisha oluxutywayo - ngakumbi ukutya, imveliso, okanye ukuthengisa - ukukhetha iifilimuziqinisekiswe ngokusingqongileyo ekujoliswe kuzo(umgquba wamashishini okanye wasekhaya) uqinisekisa ukuthotyelwa kwemithetho, intembeko yabathengi, kunye nefuthe lokwenyani lokusingqongileyo.
Ngaba ufuna uncedo lokuchonga abathengisi befilimu abaqinisekisiweyo be-PLA okanye i-cellophane? Ndinganceda ngesikhokelo sokufuna okanye uthelekiso lobuchule - undazise!
