Ezinye iimfuno ezintsha kunye notshintsho kwipakethe zikhuthaze ishishini lokupakisha eliguquguqukayo.Kwilixa elizayo,iimveliso zokupakisha eziguquguqukayoinokukhula kule miba.
1. Qonda iimveliso zokupakisha ezikhaphukhaphu kunye nezincinci.
Okwangoku, ubukhulu befilimu ye-polyester esetyenziselwaukupakishwa okuguquguqukayoidla ngokuba yi-12 microns.Ukuba ukusetyenziswa konyaka kwefilimu ye-polyester yokupakisha eChina kubalwa njengeetoni ezingama-200000, apho ifilimu ye-12 ye-microns ithatha i-50% yetotali, emva kokuba ubunzima be-microns ezili-12 buncitshiswe kwi-7 microns, ilizwe linokugcina malunga neetoni ezingama-40000 I-PET resin ngonyaka.
Ukupakishwa okuguquguqukayoisebenzisa izibonelelo kunye namandla amancinci kunezinye iindlela zokupakisha.Iindleko zayo zokupakisha, ukusetyenziswa kwezinto eziphathekayo kunye neendleko zokuthutha azincitshiswanga kakhulu kuphela, kodwa ezinye iipropati zingcono kunokupakishwa okuqinileyo.Ukusetyenziswa kweukupakishwa okuguquguqukayoinokunciphisa ukupakishwa kunye neendleko zothutho phakathi kweeprosesa, abapakishi / iibhotile, abathengisi kunye nabasebenzisi bokugqibela.Ayihlali nje indawo encinci kunopakisho oluqinileyo xa ingenanto, kodwa inokwenziwa ngokuthe ngqoiingxowa zokupakishaukusuka kwizinto ezidityanisiweyo kwindawo yokuzalisa, ngaloo ndlela kuncitshiswa ukuthuthwa kwepakethe engenanto eyenziwe ngaphambili.
Umkhwa obalulekileyo wokupakishwa kweplastiki eguquguqukayo kukuqhubeka nokubhitya, kuba uxinzelelo lwendalo esingqongileyo kunye namaxabiso aphezulu epolymer enza abathengi bafune iifilimu ezincinci.
Kuqikelelwa ukuba ukusetyenziswa kokupakishwa okuguquguqukayo ngabathengi behlabathi ngeemveliso kuya kuba yi-2010-2020 (iitoni eziliwaka).
Nangona kunjalo, kunzima ukufezekisa ukukhanya, okubandakanya ingcamango yenkqubo, iteknoloji, ukukhethwa kwezinto, izixhobo, ukuyila kunye nokusetyenziswa, kwaye kubonisa ukuphuculwa kwenqanaba lemveliso kunye nenkqubela phambili yentlalo.Ngokuqinisekileyo, ukukhanyisa ukupakishwa kweplastiki kuqhutyelwa ngeendlela ezisebenzayo kwisiseko sokuqinisekisa ukusetyenziswa kunye nokhuseleko lweemveliso zokupakisha kunye nabathengi.Into ebizwa ngokuba yi-lightweight ayakhiwanga i-jerry, kodwa iphunyezwe ngenkqubela phambili yezobuchwepheshe kunye nokutsha okuqhubekayo.
2. Ukusebenza okuphezulu, imisebenzi emininzi kunye nokuguquguquka kokusingqongileyo ngumkhombandlela wophuhliso.
Kutshanje, izinto ezidityanisiweyo eziphezulu kunye nezixhobo ezininzi ezisebenzayo ziye zaba yingqwalasela yophuhliso lweshishini, njengokumelana nobushushu obuphezulu, ukumelana nokupheka, ukupakishwa kwe-aseptic, njl."Ukupakishwa okuluhlaza" kudla ngokuqondwa "njengohlaza" lweemveliso zokupakisha, kwaye iimveliso zokupakisha ezenziwe ngezinto ezinokonakala zithathwa njengemveliso yokupakisha eluhlaza, ngoyaba ukungcoliseka kwendalo kunye nenkunkuma yemithombo eyenziwe kwinkqubo yokuvelisa, impembelelo yokupakishwa kwemveliso ebantwini. impilo kunye nokusetyenziswa kwakhona kwezinto zokupakisha.Enyanisweni, nokuba i-package material "eluhlaza" ixhomekeke kwimpembelelo yayo kwindalo ukusuka kumjikelezo wobomi bemveliso.Ukupakishwa okuluhlaza kufuneka kube luncedo kuphuhliso oluzinzileyo lwemveliso, kwaye kufuneka kugxininise kwiinkalo ezintathu, ezizezi, ukugcinwa kobutyebi, ukukhuselwa kwendalo (ukunciphisa ukungcoliseka kwamanzi, umoya kunye nengxolo), kwaye iimveliso kufuneka zihlangabezane nemigangatho yokhuseleko kunye nempilo.
Omnye umkhwa wezinto ezincinci zefilimu kukunyuka kunye nokubaluleka kweefilimu eziphezulu.Umkhwa wokuphuhliswa kwefilimu yokupakisha ukutya kukungaphumeleli okuphantsi kunye nesakhiwo sefilimu esinentsebenzo ephezulu ukwandisa ubomi beshelufu kunye nokwandisa incasa.Oku kukhula kwenzeka ngexesha apho iimpahla zazipakishwa kwizikhongozeli ezomeleleyo kwaye zijikweumgangatho ophezulu wokupakishwa oguquguqukayo.Ukupakishwa okungekuko ukutya kusetyenziswa kwishishini kunye nezolimo.
Isabelo esikhulayo seemveliso ezisemgangathweni - kubandakanywa iimveliso ezithengiswa kwi-modified atmosphere packaging (MAP) - ikwathanda ukupakishwa okuthambileyo kwezinto ezibhakiweyo.Ezinye zeemveliso zezonka ezingenagluten kunye neemveliso zasekuseni, ezifana ne-croissants, i-pancakes, ezinye izonka ezibhakiweyo kunye nemiqulu;Isonka esinombala;Kwaye ikhekhe.
