I-The ikulethela ukuqonda okujulile kwezikhwama zokupakisha ezibolayo!
Njengoba amazwe amaningi evala izikhwama zepulasitiki, izikhwama ezibolayo zisetshenziswa ezimbonini eziningi. Ukuvikela imvelo kuwumkhuba ongenakugwenywa. Ingabe ikhona imithombo encoma ukusebenzisa izikhwama zepulasitiki ezingaboli? Imiphi imikhiqizo engasetshenziswa kuyo izikhwama zepulasitiki ezingaboli? Ngikholwa ukuthi yilokhu amakhasimende amaningi a-oda izidingo zezikhwama zepulasitiki ezingaboli ngokuphelele afuna ukwazi. Namuhla, ukukhiqizwa kwe-OK Packaging kwezikhwama zepulasitiki ezibolile
1. Iyini i-biodegradable packaging?
Isikhwama sepulasitiki esibolayo siwuhlobo lwesikhwama sepulasitiki esingacekela phansi ngokuphelele amanzi, isikhutha kanye namanye ama-molecule amancane. Umthombo oyinhloko walokhu okubolayo yi-polylactic acid (PLA), ekhishwa emmbila kanye nomdumbula. IPlanethi (i-PLA) iwuhlobo olusha lwezinto ezisekelwe ku-bio nezinto ezivuselelekayo ezibolayo. Ngemva kokuvutshelwa kwe-glucose nezinye izinhlobo zokukhiqiza ukuhlanzeka okuphezulu kwe-lactic acid, i-poly (i-lactic acid) enesisindo esithile samangqamuzana yahlanganiswa ngendlela yamakhemikhali, bese kuthi i-glucose itholakale ngokukhipha i-saccharification. Lo mkhiqizo unokubola okuhle kwe-biodegradability futhi ungonakaliswa ngokuphelele amagciwane emvelo ngemva kokusetshenziswa ukukhiqiza isikhutha namanzi, angeke angcolise imvelo ngemva kokusetshenziswa. Kuzuzisa kakhulu ekuvikelweni kwemvelo futhi kuthathwa njengento ehambisana nemvelo.
Njengamanje, izinto eziyinhloko zezinto eziphilayo zezikhwama zepulasitiki eziwohlokayo zenziwe nge-PLA + PBAT, engachithwa ngokuphelele emanzini kanye ne-carbon dioxide ezinyangeni ezingu-3-6 ngaphansi kwesimo sokwenza umquba (ama-60-70 degrees). Akukho ukungcola kwemvelo. Kungani ungeza i-PBAT? I-PBAT iyi-copolymer ye-adipic acid, 1, 4-butanediol kanye ne-terephthalic acid, okuyi-biodegradable chemical synthesized aliphatic and smelling polymer. I-PBAT inokuguquguquka okuhle kakhulu futhi ingasetshenziselwa ukukhishwa kwefilimu, ukubunjwa kokushaywa, ukumbozwa kwe-extrusion nezinye izinqubo zokubumba. Ukuxutshwa kwe-PLA ne-PBAT yakhelwe ukuthuthukisa ukuqina, ukubola kwe-biodegradability kanye nokwakheka kwe-PLA.
2. Baphi abakhiqizi bezikhwama ze-biodegradable ezinegama elihle?
Emkhakheni wezikhwama zepulasitiki ezibolayo, senze umshini okhethekile wokufutha ifilimu, umshini wokunyathelisa, umshini wokusika izikhwama, i-granulator yokuvuselela imfucuza kanye nemigqa yokukhiqiza ehlukahlukene evuthiwe yezikhwama zepulasitiki ezibolayo. Imikhiqizo imboza izikhwama zevest, izikhwama zikadoti, izikhwama zezandla, izikhwama zokugqoka, izikhwama zehadiwe, izikhwama zezimonyo, izikhwama zokudla, izikhwama zekhanda lamakhadi, i-kraft paper / izikhwama ze-PLA eziyinhlanganisela, njll., ikhwalithi ezinzile, ukusebenza kahle kokukhiqiza okuphezulu, ukuphrinta okuhle, umswakama-ubufakazi , ubufakazi bokubhoboza, obungenabuthi, ukuvala kahle, ukwelula okuhle, ukuthungwa okuhle, ukuvikelwa kwemvelo.
Ukupakisha ok okunamathela kumqondo wokuvikelwa kwemvelo futhi kuzibophezele ekuthuthukisweni okusimeme kwemvelo, okuthuthukiswe ngempumelelo kulungele imboni yokupakisha kanye nempahla yokudlela ehlinzeka ngezinto zokwakha nemikhiqizo egcwele, inokuhlangenwe nakho okucebile embonini yokupakisha nokusabela ekuhlukaniseni udoti, khuthaza ukusetshenziswa kabusha kwezinsiza, futhi uthuthukise ngenkuthalo imikhiqizo engaboli ngokugcwele yezinga lokudla.
3. Yimiphi imikhiqizo engasetshenziswa kuyo izikhwama ezingaboli?
Izikhwama zepulasitiki ezibolayo zisetshenziswa kakhulu kumahembe, ukunitha, izingubo, izingubo, izindwangu, ukudla, ihardware, izinto zikagesi, izimonyo nezinye izimboni. Izikhwama zepulasitiki ezibolayo zinemiklamo eminingi yokuvala, njengethambo lokunamathela, uziphu, itheyiphu, njll., kanye nezikhwama zepulasitiki ezibolayo zihlanganiswe nephepha, elingagoqa isitho esingaphansi. Manje, izikhwama zepulasitiki ezibolayo zingena kuzo zonke izigaba zokuphila, futhi kunezinhlobonhlobo zezitayela; Ngokuzayo, izikhwama zepulasitiki ezibolayo zizoba umkhiqizo ophelele wemboni yokupakisha.
