Ukupakishwa kwepulasitiki
Izikhwama zokupakisha zeplastiki ziyindlela ethandwayo yokupakishwa okulula ngenxa yokuqina kwazo, ukuguquguquka nezindleko eziphansi. Kodwa-ke, akuzona zonke izinto zepulasitiki ezilungele ukufakwa okulula. Nazi ezinye zezinto zepulasitiki ezivame kakhulu ezisetshenziselwa ukupakisha izikhwama:
Polyethylene (pe)
I-PolyethYlene izikhwama zepulasitiki ezisetshenziswa kabanzi. Kuyinto engasindi futhi eguquguqukayo engabunjwe kalula ibe ngosayizi abehlukene nosayizi. Izikhwama ze-PE nazo zimelana nomswakama futhi zingagcina ukudla okulula isikhathi eside. Kodwa-ke, izikhwama ze-PE azilungele ukudla okulula okushisayo njengoba zingancibilika emazingeni okushisa aphezulu.
I-Polypropylene (PP)
I-PolyPropylene iyinto eqinile futhi eqinile yepulasitiki esetshenziselwa izikhwama zokupakisha. Izikhwama ze-PP zimelana namafutha namafutha, zizenze zilungele ukupakisha okulula okunamafutha anjengama-chip kanye nama-popcorn. Izikhwama ze-PP nazo ziphephile-ziphephile, ezibenza babe ukukhetha okuthandwayo kokupakishwa okulula.
I-Polyvinyl Chloride (PVC)
I-Polyvinyl Chloride, eyaziwa nangokuthi i-PVC, iyithuluzi leplastiki elivame ukusetshenziswa ezikhwameni zokufaka okulula. Izikhwama ze-PVC ziyavumelana nezimo futhi zihlala isikhathi eside, futhi zingaphrintwa kalula ngemiklamo emibalabala. Kodwa-ke, izikhwama ze-PVC azilungele ukudla okulula okushisayo njengoba zingakhipha amakhemikhali ayingozi lapho efudumele.
Ngamafuphi, izikhwama zokupakisha zepulasitiki ziyindlela ethandwayo yokupakishwa okulula ngenxa yokuqina kwabo, ukuvumelana nezimo nezindleko eziphansi. Kodwa-ke, kubalulekile ukukhetha impahla yepulasitiki efanelekile yokufaka okulula ukuqinisekisa ukuphepha nekhwalithi yokudla okulula. I-PE, i-PP ne-PVC ezinye zezinto zepulasitiki ezivame kakhulu ezisetshenziselwa ukufakwa kwezikhwama ze-snack, ngalinye linezinzuzo zabo kanye nemikhawulo.
Izikhwama zokupakisha ezingathandeki
Izikhwama zokupakisha ezingathandeki ze-BiodeGradable ziyindlela enobungane yemvelo yokufakwa okulula. Lezi zikhwama zenzelwe ukudiliza ngokwemvelo ngokuhamba kwesikhathi, zinciphisa inani lemfucumfucu eligcina ekulahlekelweni komhlaba. Izinhlobo ezimbili ezivamile zezinto ezisetshenziswayo ze-biodegradable ezisetshenziswa ezikhwameni zokupakisha ze-snack yi-polylactic acid (PLA) kanye nePolyhydroxyalkataates (Pha).
I-Polylactic acid (PLA)
I-Polylactic acid (PLA) iyi-polymer engathandeki eyenziwe ngemithombo evuselelekayo efana nesitashi sommbila, umoba, kanye nomdumbula. I-PLA ithole ukuthandwa eminyakeni yamuva ngenxa yekhono layo lokudiliza ngokwemvelo emvelweni. Kubuye kube nemali, okusho ukuthi kungadilizwa ku-organic date engasetshenziswa ukucebisa inhlabathi.
I-PLA ivame ukusetshenziswa ezikhwameni zokupakisha okulula ngoba iqinile futhi iqinile, kepha isasebenza. Futhi inesifiso sekhabhoni esiphansi, okwenza kube yindlela enobungane yemvelo.
Polyhydroxyalkataates (Pha)
I-Polyhydroxyalkataates (i-PHA) ngolunye uhlobo lwe-polymer olungenakusebenza olungasetshenziswa ezikhwameni zokupakisha. I-PHA ikhiqizwa amagciwane futhi iyinto egcwele indawo ehlukahlukene, kufaka phakathi izindawo zasolwandle.
I-PHA iyinto eguquguqukayo engasetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi ukufakwa okulula. Iqinile futhi ihlala isikhathi eside, kepha futhi i-biodegradable, okwenza kube yikhethelo elihle labakhiqizi bemvelo abanemvelo.
Ekuphetheni, izikhwama zokupakisha ze-biodegramable snack ezinjenge-PLA ne-PHA ziyinketho enhle yokuthola abakhiqizi be-snack babheke ukunciphisa umthelela wabo wezemvelo. Lezi zinto ziqinile, zihlala ziqinile, futhi zingenakuqina, zibelwenza ukukhetha okuhle kokupakishwa okulula.
Izikhwama zokupakisha iphepha
Izikhwama zokupakisha iphepha ziyindlela engcono futhi eqhubekayo yokufakwa okulula. Zenziwe ngemithombo evuselelekayo futhi zingavuselelwa kabusha, zihlanganiswe noma zisetshenziswe kabusha. Izikhwama zephepha nazo zisindile, kulula ukuzisingatha futhi zibiza kakhulu. Zilungele ukupakishwa okudla okulula okufana nama-chip, ama-popcorn namantongomane.
Izikhwama zokupakisha iphepha ziyatholakala ngezinhlobo ezahlukene, kufaka phakathi:
Izikhwama zephepha le-Kraft:Kwenziwe nge-pulp engaguquki noma ehlanganisiwe, lezi zikhwama ziqinile, zihlala ziqinile, futhi zinokubukeka okungokwemvelo nokuzizwa.
Izikhwama zephepha elimhlophe:Kwenziwe nge-pulp ehlanganisiwe, lezi zikhwama zibushelelezi, zihlanzekile, futhi zinokubukeka okukhanyayo.
Izikhwama zephepha le-GREFEProof:Lezi zikhwama zihlanganiswe ngesendlalelo sezinto ezibonakalayo ezingavikeleki kwamafutha, zibenze zilungele ukupakisha ukudla okulula okunamafutha.
Izikhwama zamaphepha zingaphrinta ngemiklamo yangokwezifiso, ama-logo, kanye nokufaka uphawu, kubenza ithuluzi lokumaketha elihle lezinkampani ezilula. Zingafakwa futhi nezici ezifana nama-zippers ezisebenzisekayo, ama-notches ahlukahlukene, namafasitela acacile ukuze athuthukise lula nokubonakala.
Kodwa-ke, izikhwama zephepha zinokulinganiselwa okuthile. Azilungele ukupakishwa okumanzi noma okumanzi okumanzi ngangokunokwenzeka ukudiliza noma ukuba yi-soggy. Baphinde babe nesithiyo esilinganiselwe esilinganiselwe umswakama, umoya-mpilo, nokukhanya, okungathinta impilo yeshelufu kanye nekhwalithi yokudla okulula.
Sekukonke, izikhwama zokupakisha zamaphepha ziyindlela esimeme futhi eguquguqukayo yokufakwa okulula, ikakhulukazi okulula okulula. Banikeza ukubukeka kwemvelo futhi bazizwe, bayabiza kakhulu, futhi bangenziwa ngokwezifiso ukuze bahlangabezane nezidingo ezithile zokumaketha kanye nokukhangisa.
