Huinga Pēke Tunu Konumohe Ripene me te Whakamomona Hāora

Ko te putea retort he putea kiriata kirihou hiato ka taea te whakamahana, he pai ake i ngā ipu kēne me ngā putea kirihou ātete wai kohua.
Ka taea te waiho i te kai kia kore e pakaru i roto i te putea, ka whakahoromatatia, ka whakamahanatia ki te pāmahana teitei (i te nuinga o te wā i te 120~135°C), kātahi ka haria ki waho ki te kai. Neke atu i te tekau tau te roa o te whakamātautau, he ipu pai rawa atu tēnei mō te takai hoko. He pai mō te takai i ngā hua mīti me te pīni soya, he watea, he akuaku, he whai hua hoki, ā, ka taea te pupuri i te reka taketake o te kai, e pai ana ki ngā kaihoko.
I ngā tau 1960, i hangaia e te Hononga o Amerika te kiriata konumohe-kirihou hei whakaoti rapanga mō ngā takai kai rererangi. E whakamahia ana hei takai i ngā kai mīti, ā, ka taea te penapena i te pāmahana rūma mā te whakahoromata i te pāmahana teitei me te pēhanga teitei, ā, neke atu i te kotahi tau te roa o te oranga. He rite te mahi a te kiriata konumohe-kirihou ki te mahi a te kēne, he ngawari, he māmā hoki, nō reira i tapaina ai ko te kēne ngohengohe. I tēnei wā, ko ngā hua mīti he roa te oranga ka penapenahia i te pāmahana rūma, pērā i te whakamahi i ngā ipu takai mārō, te whakamahi rānei i ngā kēne pereti tine me ngā pounamu karāhe; ki te whakamahi i te takai ngāwari, tata katoa e whakamahi ana i ngā kiriata konumohe-kirihou.

Te tukanga hanga o te putea retort ātete pāmahana teitei I tēnei wā, ko te nuinga o ngā putea retort o te ao e hangaia ana mā te tikanga whakaranu maroke, ā, ka taea hoki te hanga i ētahi mā te tikanga whakaranu kore-whakarewa, mā te tikanga whakaranu tahi-whakaputa rānei. He teitei ake te kounga o te whakaranu maroke i te whakaranu kore-whakarewa, ā, he tika ake te whakaritenga me te whakakotahitanga o ngā rauemi me te whānui ake i te whakaranu tahi-whakaputa, ā, he pono ake te whakamahi.

Hei whakatutuki i ngā whakaritenga mahi o te putea retort, ko te paparanga o waho o te hanganga he mea hanga ki te kiriata polyester kaha-teitei, ko te paparanga o waenganui he mea hanga ki te pepa konumohe ārai-mārama, ā, ko te paparanga o roto he mea hanga ki te kiriata polypropylene. E toru ngā hanganga paparanga: PET/AL/CPP, PPET/PA/CPP; ko te hanganga paparanga-whā ko PET/AL/PA/CPP.
