Iindaba-Yintoni iFayibha eMolded Pulp Packaging?

Kwicandelo lenkonzo yokutya yanamhlanje, ukupakishwa kwefayibha ezibunjiweyo kuye kwaba sisisombululo esiyimfuneko, ukubonelela abathengi ngezikhongozeli zokutya ezikhuselekileyo nezinobuhlobo nokusingqongileyo kunye nokuqina, amandla kunye ne-hydrophobicity. Ukusuka kwiibhokisi zokukhupha ukuya kwizitya ezilahlwayo kunye neetreyi, ukupakishwa kwefayibha ezibunjiweyo akuqinisekisi kuphela ucoceko lokutya kunye nemfezeko, kodwa ikwakhawulelana nemfuno yentengisoukupakishwa okuzinzileyoizixhobo. Eli nqaku liza kuhlolisisa inkcazo yokupakishwa kwefayibha, ukubaluleka kwezisombululo zemichiza, kunye neentlobo ezahlukeneyo zokupakisha ifayibha, ejolise ekunikeni abafundi ukuqonda okubanzi.

Yintoni iPackaging yeFayibha eBunjiweyo kwaye kutheni ibalulekile

Ukupakishwa kwefayibha ezibunjiweyo yimveliso yokupakisha esebenzisa itekhnoloji yokubumba ukwenza izinto zefiber (njengepulp, i-bamboo pulp, isitashi sombona okanye i-pulp yommoba) kwimilo ethile. Inkqubo yemveliso yokupakishwa kwefayibha ezibunjiweyo ihambelana nokusingqongileyo kuba uninzi lwemathiriyeli ekrwada ivela kwimithombo ehlaziyekayo kwaye inkunkuma kwinkqubo yemveliso inokuphinda isetyenziswe kwaye isetyenziswe kwakhona. Olu hlobo lokupakisha alunayo nje kuphela iipropathi ezilungileyo zoomatshini ezifana nokuqina kunye namandla, kodwa zikwanazo ne-biodegradability egqwesileyo kwaye zinempembelelo encinci kokusingqongileyo. Ke ngoko, ithandwa kakhulu kwintsimi yenkonzo yokutya kuba ayikhuseli kuphela ukutya ekungcoleni kwangaphandle, kodwa ikwagcina ukutsha kunye nokuthembeka kokutya ngexesha lokuhamba nokugcinwa. Ukuqina kunye namandla okupakishwa kwefayibha ezibunjiweyo kuyenza ilungele ukuthwala ukutya okunzima, ngelixa i-hydrophobicity yayo iqinisekisa ukuba ukutya akubi manzi ngenxa yokupakishwa.

Izicelo zokuPakisha iiFayibha ezibunjiweyo zeNkonzo yoKutya

Kwicandelo lenkonzo yokutya,ukupakishwa kwefayibha ezibunjiweyoisetyenziswe ngokubanzi kwaye ibe yinxalenye yesiqheloukupakishwa kokutya okufana nezitya, iitreyi kunye neebhokisi zokukhupha. Ezi phakheji azinikezeli kuphela ukhuseleko oluyimfuneko ukuze kuqinisekiswe ukuba ukutya akonakali ngexesha lokuthutha kunye nokugcinwa, kodwa kunokutshatyalaliswa ngokukhawuleza emva kokusetyenziswa ukunciphisa ukungcoliseka kwendalo. Ngokomzekelo, izitya zefiber ezibunjiweyo kunye neetreyi ziyakwazi ukumelana nokutshintsha kweqondo elithile kwaye zifanelekile ukufudumeza i-microwave okanye ifriji yefriji. Ukongeza, uyilo lweebhokisi zokukhupha zikwagxile ekululameni kunye nokuqina ukuqinisekisa ukhuseleko kunye nokutsha kokutya ngexesha lokuhamba.

Ubunakho beZisombululo zeMichiza yeFayibha ebunjiweyo

Ukuze kuhlangatyezwane neemfuno zeemeko ezahlukeneyo zokusetyenziswa, ukupakishwa kwefayibha ezibunjiweyo kufuneka zibe nezinto ezahlukeneyo zokusebenza. Ezi mpawu zisebenzayo, eziphunyezwe ngokuyinhloko ngezisombululo zeekhemikhali zefiber ezibunjiweyo, zibandakanya ukuqina, amandla kunye ne-hydrophobicity. Umzekelo, ngokongeza izongezo zekhemikhali ezifanelekileyo kwi-pulp, amandla eukupakishwa kwefayibha ezibunjiweyoinokwandiswa kakhulu, iyenze ukuba kungabi lula ukonakala okanye ukwaphuka xa ithwele imithwalo enzima. Ngelo xesha, unyango lwe-hydrophobic lunokuthintela ngokufanelekileyo ukungena kwamanzi kunye nokuqinisekisa ucoceko kunye nokhuseleko lokupakishwa kokutya. Ezi zisombululo zekhemikhali azinyusi nje kuphela ukusebenza kokupakishwa kwefayibha ezibunjiweyo kodwa zikwaqinisekisa imigangatho yococeko kwimveliso yokugqibela.

Izisombululo zeekhemikhali zefiber ezibunjiweyo

Ukuqinisekisa le misebenzi iyimfuneko yeukupakishwa kwefayibha ezibunjiweyo, izicombululo zemichiza zidlala indima ebalulekileyo. Ngonyango oluchanekileyo lwekhemikhali, ukuqina kunye nokomelela kwemathiriyeli yefiber kunokongezwa ngelixa kugcinwa i-hydrophobicity yazo yendalo. Olu nyango lweekhemikhali lukwabandakanya nokuqinisekisa ucoceko lwemveliso yokugqibela, ukubonelela abathengi ngeendlela ezikhuselekileyo zokupakisha ukutya ngokuthintela ukukhula kweebhaktheriya kunye ne-microorganisms. Ukongeza, izisombululo zeekhemikhali zikwazibophelele ekuphuculeni ukusebenziseka kwakhona kunye ne-biodegradability yokupakishwa kwefayibha ebunjiweyo, ngaloo ndlela kuncitshiswa impembelelo kokusingqongileyo.

Iindidi ezahlukeneyo zokuPakisha iiFayibha ezibunjiweyo

Ukupakishwa kwefayibha ezibunjiweyo zenziwa ikakhulu kwintlama yephepha, kodwa njengokuba itekhnoloji ikhula kwaye iimfuno zentengiso zitshintsha, kuye kwavela iindlela ezahlukeneyo zokukhetha izinto ezikrwada. Ukongeza kwimveliiphepha elihlaziyiweyo, i-bamboo pulp kunye nentlaka yeswekileziye zaba zezinye ezidumileyo ngenxa yokukhula kwazo ngokukhawuleza kunye nokuvuselelwa. Ukongeza, isitashi sombona sikwasetyenziswa kwimveliso yokupakisha ifayibha ezibunjiweyo kuba ayisosixhobo esihlaziyekayo kuphela, kodwa sinokonakala phantsi kweemeko ezithile. Umzekelo owenziweyo kukubunjwaikomityi yekofu yefiber yeswekile, esebenzisa iimpawu zendalo zomthombe wommoba ukunika isisombululo sokupakisha esivumelana nokusingqongileyo nesisebenzisekayo.

Uzinzo

Ungcoliseko lweplastiki ngomnye weyona miba icinezelayo yokusingqongileyo. Kukho ubungqina obuninzi bokuba iplastiki ingcolisa amanzi ethu, izilwanyana zasendle kwaye inefuthe elibi kwimpilo yabantu. Ukupakishwa kwePlastiki kunegalelo elikhulu kwingxaki yehlabathi kwaye ukukhangela ukupakishwa kwasimahla kweplastiki kuye kwanceda ukutyhala imfuno yokupakishwa okusekwe kwifiber.

Amaxabiso okurisayikilishwa kweplastiki aphantsi kakhulu. Ngokuthelekisa, izinga lokubuyisela ukupakishwa kwephepha kunye nekhadibhodi lilungile kwaye uthungelwano lokuzibuyisela kwakhona ukuze zisetyenziswe ngokutsha ziphuhliswe kakuhle. Ukupakishwa kwe-pulp okubunjiweyo yinxalenye yenkqubo eyomeleleyo ye-loop evaliweyo - ukupakishwa kwe-pulp kwenziwa ngezinto zefiber ezihlaziyiweyo kwaye zinokuphinda zisetyenziswe ngokulula emva kobomi bayo obuluncedo kunye nezinye izinto zephepha kunye nekhadibhodi.

Ikamva lokupakishwa kwefayibha ezibunjiweyo

Njengoko ulwazi lwehlabathi lophuhliso oluzinzileyo kunye nokukhuselwa kwendalo kuyaqhubeka ukwanda, ikamva lokupakishwa kwefiber ebunjiweyo lizele ngamathuba.
