Ukupakisha kwePlastiki
Izikhwama zepulasitiki zokupakisha ziyinketho ethandwayo yokupakisha ukudla okulula ngenxa yokuqina kwazo, ukuguquguquka, kanye nezindleko eziphansi.Kodwa-ke, akuzona zonke izinto zepulasitiki ezifanele ukupakishwa kwe-snack.Nazi ezinye zezinto ezivame kakhulu zepulasitiki ezisetshenziselwa izikhwama zokupakisha zokudla okulula:
I-Polyethylene (PE)
I-Polyethylene izikhwama zepulasitiki ezisetshenziswa kakhulu.Kuyinto engasindi futhi eguquguqukayo engabunjwa kalula ibe yizimo nobukhulu obuhlukene.Izikhwama ze-PE nazo zimelana nomswakama futhi zingagcina ukudla okulula kusha isikhathi eside.Kodwa-ke, izikhwama ze-PE azifanelekile ukudla okulula okushisayo njengoba zingancibilika emazingeni okushisa aphezulu.
I-Polypropylene (PP)
I-Polypropylene iyimpahla yepulasitiki eqinile futhi ehlala isikhathi eside evame ukusetshenziselwa izikhwama zokupakisha ukudla okulula.Izikhwama ze-PP azikwazi ukumelana nowoyela namafutha, okuzenza zilungele ukupakisha ukudla okulula okunamafutha njengama-chips nama-popcorn.Izikhwama ze-PP nazo ziphephile nge-microwave, okuzenza zibe yinketho ethandwayo yokupakisha ukudla okulula.
I-Polyvinyl Chloride (PVC)
I-Polyvinyl Chloride, eyaziwa nangokuthi i-PVC, iyimpahla yepulasitiki evame ukusetshenziselwa izikhwama zokupakisha ukudla okulula.Izikhwama ze-PVC ziyavumelana nezimo futhi zihlala isikhathi eside, futhi zingaphrintwa kalula ngemiklamo enemibala.Kodwa-ke, izikhwama ze-PVC azifanelekile ukudla okulula okushisayo njengoba zingakhulula amakhemikhali ayingozi uma kushisa.
Kafushane, izikhwama zepulasitiki zokupakisha ziyinketho ethandwayo yokupakisha ukudla okulula ngenxa yokuqina kwazo, ukuguquguquka, kanye nezindleko eziphansi.Kodwa-ke, kubalulekile ukukhetha impahla yepulasitiki efanele yokupakisha ukudla okulula ukuze uqinisekise ukuphepha kanye nekhwalithi yokudla okulula.I-PE, PP kanye ne-PVC ngezinye zezinto ezivame kakhulu zepulasitiki ezisetshenziselwa izikhwama zokupakisha zokudla okulula, ngasinye sinezinzuzo kanye nokulinganiselwa kwaso.
I-Biodegradable Packaging Bags
Izikhwama zokupakisha ezibolayo ziyindlela evumelana nemvelo yokupakisha ukudla okulula.Lezi zikhwama ziklanyelwe ukudilika ngokwemvelo ngokuhamba kwesikhathi, ukunciphisa inani lemfucuza egcina isendaweni yokulahla imfucumfucu.Izinhlobo ezimbili ezijwayelekile zezinto ezibolayo ezisetshenziswa ezikhwameni zokupakisha ukudla okulula yi-Polylactic Acid (PLA) kanye ne-Polyhydroxyalkanoates (PHA).
I-Polylactic Acid (PLA)
I-Polylactic Acid (PLA) iyi-polymer ekwazi ukubola eyenziwe ngezinto ezivuselelekayo ezifana nesitashi sombila, umoba, nomdumbula.I-PLA ithole ukuthandwa eminyakeni yamuva nje ngenxa yekhono layo lokubhidlika ngokwemvelo endaweni ezungezile.Iyavundisa futhi, okusho ukuthi ingahlukaniswa ibe izinto eziphilayo ezingasetshenziswa ukunothisa umhlabathi.
I-PLA ivame ukusetshenziswa ezikhwameni zokupakisha ukudla okulula ngoba iqinile futhi ihlala isikhathi eside, kodwa isabola.Iphinde ibe ne-low carbon footprint, okuyenza ibe inketho evumelana nemvelo.
I-Polyhydroxyalkanoates (PHA)
I-Polyhydroxyalkanoates (PHA) ingolunye uhlobo lwe-polymer ebolayo engasetshenziswa ezikhwameni zokupakisha ukudla okulula.I-PHA ikhiqizwa amabhaktheriya futhi iyakwazi ukubola ezindaweni ezihlukahlukene, kuhlanganise nezindawo zasolwandle.
I-PHA iwumsebenzi oguquguqukayo ongasetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi ukupakishwa kwesnack.Iqinile futhi ihlala isikhathi eside, kodwa futhi iyabola, okuyenza ibe yinketho ekahle kubakhiqizi abakhathalela imvelo.
Sengiphetha, izikhwama zokupakisha ukudla okulula okungaboli njenge-PLA ne-PHA ziyisinqumo esihle kubakhiqizi bamaswidi abafuna ukunciphisa umthelela wabo kwezemvelo.Lezi zinto ziqinile, zihlala isikhathi eside, futhi ziyabola, okuzenza zibe ukukhetha okuhle kokupakishwa kwesnack.
Izikhwama zokupakisha zamaphepha
Izikhwama zokufaka amaphepha ziyinketho eco-friendly futhi eqhubekayo yokupakisha ukudla okulula.Zenziwe ngezinsiza ezivuselelekayo futhi zingagaywa kabusha, zenziwe umquba noma ziphinde zisetshenziswe.Izikhwama zamaphepha nazo azisindi, ziphathwa kalula futhi zingabizi.Zilungele ukupakisha ukudla okulula okomile njengama-chips, ama-popcorn namantongomane.
Izikhwama zokufaka amaphepha zitholakala ngezinhlobo ezahlukene, okuhlanganisa:
Izikhwama zephepha le-Kraft:ezenziwe nge-pulp engaxutshwe namanzi noma e-bleached, lezi zikhwama ziqinile, zihlala isikhathi eside, futhi zinokubukeka kwemvelo nokuzizwa.
Izikhwama Zephepha Elimhlophe:ezenziwe nge-bleached pulp, lezi zikhwama zibushelelezi, zihlanzekile, futhi zinokubukeka okukhanyayo.
Izikhwama Zephepha EzingenaGrisi:lezi zikhwama zimbozwe ungqimba lwezinto ezimelana namafutha, okuzenza zilungele ukupakisha ukudla okulula okunamafutha.
Izikhwama zamaphepha zingaphrintwa ngemiklamo yangokwezifiso, ama-logo, kanye nebhrendi, okuzenza zibe ithuluzi elihle kakhulu lokuthengisa lezinkampani zokudla okulula.Angaphinda afakwe izici ezifana neziphuphu ezivalekayo, izinqamuleli ezidabulayo, namafasitela acacile ukuze kuthuthukiswe ukunethezeka nokubonakala.
Nokho, izikhwama zamaphepha zinemikhawulo ethile.Azikulungele ukupakisha ukudla okulula okumanzi noma okumanzi njengoba zingadabula kalula noma zibe muncu.Futhi banesithiyo esilinganiselwe ngokumelene nomswakama, umoya-mpilo, nokukhanya, okungathinta impilo yeshalofu kanye nekhwalithi yokudla okulula.
Sekukonke, izikhwama zokupakisha zamaphepha ziyinketho eqhubekayo futhi eguquguqukayo yokupakisha ukudla okulula, ikakhulukazi ukudla okulula okomile.Zinikeza ukubukeka kwemvelo nomuzwa, zibiza izindleko, futhi zingenziwa ngendlela oyifisayo ukuze zihlangabezane nezidingo ezithile zokumaketha nokumaketha.
