Kwihlabathi elikhulu lokupakishwa kokutya, okuthambileyoukupakisha ifilimu rolliphumelele inkoliseko yemarike ngenxa yobunzima bayo, intle, kwaye kulula ukuyiqhuba. Nangona kunjalo, ngelixa silandela uyilo lokuyila kunye nobuhle bokupakisha, sihlala sikujongela phantsi ukuqonda kweempawu zezixhobo zokupakisha ngokwazo. Namhlanje, makhe sityhile imfihlakalo yefilimu yokupakisha ethambileyo yokutya kwaye siphonononge indlela yokufikelela ukuqonda okucwangcisiweyo kunye neenxalenye zoshicilelo kuyilo lwesakhiwo sokupakisha, ukwenza ukupakishwa kugqibelele ngakumbi.
Amagama afinyeziweyo kunye neempawu ezihambelanayo zeplastiki
Okokuqala, kufuneka sibe nokuqonda okusisiseko kwezinto ezisetyenziswa ngokuqhelekileyo zeplastiki. Kwiifilimu zokupakisha ezithambileyo zokutya, izinto zeplastiki eziqhelekileyo ziquka i-PE (i-polyethylene), i-PP (i-polypropylene), i-PET (i-polyethylene terephthalate), i-PA (nylon), njl. ukumelana, ukusebenza komqobo, njl.
I-PE (i-polyethylene): Le yimathiriyeli yeplastiki eqhelekileyo kunye nokungafihli kakuhle kunye nokuguquguquka, ngelixa ixabiso eliphantsi kakhulu. Nangona kunjalo, ukuxhathisa kwayo kubushushu kwaye ayikufanelanga ukupakisha ukutya okuphekiweyo okanye okukhenkcezisiweyo kumaqondo aphezulu.
I-PP (i-polypropylene): Izinto ze-PP zinokumelana nokushisa okuphezulu kwaye ziyakwazi ukumelana nokushisa okuphezulu ngaphandle kokuguqulwa, ngoko ke isetyenziswa ngokuqhelekileyo ekupakishweni kokutya okufuneka kufakwe i-steamed okanye iqhwa.
I-PET (i-polyethylene terephthalate): Izinto ze-PET zinokucaca okugqwesileyo kunye namandla, kunye nokumelana nobushushu obulungileyo kunye neempawu zokuthintela, ngoko ke zisetyenziswa ngokuqhelekileyo kwipakethe yokutya efuna ukukhanya okuphezulu kunye namandla.
I-PA (iNylon): Izinto ze-PA zineempawu ezintle zomqobo, ezinokuthintela ngokufanelekileyo ukungena kweoksijini kunye namanzi, kunye nokugcina ukutsha kokutya. Kodwa xa kuthelekiswa nezinye izinto, ixabiso le-PA liphezulu.
Indlela yokukhetha fizinto zokupakisha ood
Emva kokuqonda iimpawu zezinto ezahlukeneyo zeplastiki, sinokukhetha izixhobo ezifanelekileyo zokuyilwa kwesakhiwo sokupakisha ngokusekelwe kwiimpawu kunye neemfuno zemveliso. Ngelo xesha, xa ukhetha i-substrates yokushicilela, ukufaneleka kokuprinta kunye neendleko zezixhobo kufuneka ziqwalaselwe.
Khetha izinto ezifanelekileyo ezisekelwe kwiimpawu zemveliso: umzekelo, ukutya okufuneka kufakwe i-steamed okanye iqhwa, sinokukhetha izinto zePP ezinokumelana nokushisa okulungileyo; Kwiimveliso ezifuna ukucaca okuphezulu kunye namandla, sinokukhetha izinto zePET.
Qwalasela ukufaneleka koshicilelo: Izinto ezahlukeneyo zineemfuno ezahlukeneyo zokuncamathelisa inki kunye nokoma. Xa ukhetha i-substrates yokushicilela, kufuneka siqwalasele ukufaneleka koshicilelo lwezixhobo zokuqinisekisa ubuhle kunye nefuthe lokushicilela ixesha elide.
Ulawulo lweendleko: Ngelixa sidibana neempawu zemveliso kunye nokufaneleka koshicilelo, kufuneka silawule iindleko kangangoko sinakho. Ngokomzekelo, xa ikhona, sinokubeka phambili izinto ze-PE kunye neendleko eziphantsi.
Isishwankathelo, kwi-packaging structure design yokutyaiifilimu zokupakisha zeplastiki, akuyomfuneko ukuba ube nokuqonda ngokucokisekileyo i-substrates yokushicilela, kodwa ukuqonda okusisiseko kuyafuneka. Kungale ndlela kuphela esinokuthi siqinisekise ukhuseleko kunye nokutsha kokutya ngelixa siyila ukupakishwa okuhle kunye nokusebenzayo.
