Ezinye izidingo ezintsha kanye nezinguquko ekufakweni kukhuthaze imboni yokupakisha eguquguqukayo.Esikhathini esizayo,imikhiqizo yokupakisha eguquguqukayozingathuthuka kulezi zici.
1. Qaphela imikhiqizo yokupakisha engasindi futhi enezindonga ezincane.
Njengamanje, ukushuba kwefilimu ye-polyester esetshenziselwaukupakisha nezimongokuvamile i-12 microns.Uma ukusetshenziswa konyaka kwefilimu ye-polyester ukupakishwa eChina kubalwa njengamathani angama-200000, lapho ifilimu eyi-microns eyi-12 ibalelwa ku-50% yenani eliphelele, ngemuva kokuthi ugqinsi lwama-microns ayi-12 luncishiswe lwaba ama-microns ayi-7, izwe lingonga amathani angama-40000 I-PET resin ngonyaka.
Ukupakisha okuguquguqukayoisebenzisa izinsiza namandla amancane kunezinye izinhlobo zokupakisha.Izindleko zayo zokupakisha, ukusetshenziswa kwezinto ezibonakalayo kanye nezindleko zokuthutha azincishiswa kakhulu kuphela, kodwa futhi ezinye izakhiwo zingcono kunokupakisha okuqinile.Ukusetshenziswa kweukupakisha nezimoinganciphisa izindleko zokupakisha nezokuthutha phakathi kwamaphrosesa, amapaki/amabhodlela, abathengisi nabasebenzisi bokugcina.Ayithathi nje isikhala esincane kunokupakishwa okuqinile lapho ingenalutho, kodwa futhi ingenziwa ngokuqondile.izikhwama zokupakishakusuka ezintweni ezihlanganisiwe endaweni yokugcwalisa, ngaleyo ndlela kuncishiswe ukuthuthwa kokupakishwa okungenalutho okwenziwe ngaphambilini.
Umkhuba obalulekile wokupakishwa kwepulasitiki okuguquguqukayo ukuqhubeka nokuncipha, ngoba ukucindezela kwemvelo kanye namanani aphezulu e-polymer kwenza amakhasimende afune amafilimu amancane.
Kubikezelwa ukuthi ukusetshenziswa kokupakishwa okuguquguqukayo ngabathengi bomhlaba wonke ngemikhiqizo kuzoba ngu-2010-2020 (amathani ayizinkulungwane).
Kodwa-ke, kunzima ukufeza i-lightweight, ehlanganisa umqondo wenqubo, ubuchwepheshe, ukukhethwa kwezinto ezibonakalayo, imishini, ukuklama nokusetshenziswa, futhi kubonisa ukuthuthukiswa kwezinga lokukhiqiza kanye nenqubekelaphambili yomphakathi.Vele, ukukhanya kokupakishwa kwepulasitiki kwenziwa ngezindlela ezisebenzayo ngesisekelo sokuqinisekisa ukusebenziseka nokuphepha kwemikhiqizo yokupakisha kanye nabathengi.Okubizwa nge-lightweight akwakhiwanga i-jerry, kodwa kuzuzwa ngenqubekelaphambili yezobuchwepheshe kanye nokuqamba okusha okuqhubekayo.
2. Ukusebenza okuphezulu, imisebenzi eminingi kanye nokuvumelana nezimo zemvelo kuyisiqondiso sentuthuko.
Muva nje, izinto ezihlanganisiwe ezisebenza kahle kakhulu nezinemisebenzi eminingi seziphenduke ingqikithi yokuthuthukiswa kwemboni, njengokumelana nezinga lokushisa eliphezulu, ukumelana nokupheka, ukupakishwa kwe-aseptic, njll. Amanye amabhizinisi anokuqonda okuthile mayelana nokuthuthukiswa kwemikhiqizo yokupakisha eluhlaza."Ukupakishwa okuluhlaza" kuvame ukuqondwa ngokuthi "ukuhlaza" kwemikhiqizo yokupakisha, futhi imikhiqizo yokupakisha eyenziwe ngezinto ezonakele ithathwa njengemikhiqizo yokupakisha eluhlaza, indiva ukungcoliswa kwemvelo kanye nemfucumfucu yezinsiza ekhiqizwa inqubo yokukhiqiza, umthelela wemikhiqizo yokupakisha kubantu. ezempilo kanye nokusetshenziswa kabusha kwezinto zokupakisha.Eqinisweni, ukuthi impahla yokupakisha "iluhlaza" kuncike emthelela wayo endaweni ezungezile kusukela kuwo wonke umjikelezo wokuphila womkhiqizo.Ukupakishwa okuluhlaza kufanele kube nomthelela ekuthuthukisweni okusimeme kokukhiqiza, futhi kufanele kugxile ezintweni ezintathu, okungukuthi, ukongiwa kwezinsiza, ukuvikelwa kwemvelo (ukunciphisa ukungcoliswa kwamanzi, umkhathi nomsindo), futhi imikhiqizo kufanele ihlangabezane nezindinganiso zokuphepha nempilo.
Omunye umkhuba wezinto zokwakha zefilimu encane kakhulu ukuphakama nokubaluleka kwamafilimu asebenza kahle.Umkhuba wokuthuthuka wefilimu yokupakisha ukudla ukungeneka okuphansi kanye nesakhiwo sefilimu esisebenza kahle kakhulu ukuze kunwetshwe impilo yeshalofu nokuthuthukisa ukunambitheka.Lokhu kukhula kwenzeka ngesikhathi lapho izimpahla zipakishwa ezitsheni eziqinile futhi ziguqulwa zibeizinga okusezingeni eliphezulu nezimo.Ukupakishwa okungekona ukudla kusetshenziswa ezimbonini nakwezolimo.
Isabelo esikhulayo semikhiqizo yekhwalithi - okuhlanganisa nemikhiqizo ethengiswa ku-modified atmosphere packaging (MAP) - futhi ithanda ukupakishwa okuthambile kwezimpahla ezibhakiwe.Eminye yemikhiqizo isinkwa esingenayo i-gluten kanye nemikhiqizo yasekuseni, njengama-croissants, ama-pancake, isinkwa esibhakiwe namaroli;Isinkwa esinombala;Futhi ikhekhe.
