Vacuum packaging o le ave lea o le ea i totonu o le pusa afifi ma faʻamaufaʻailoga mea e ausia ai le faʻamoemoe o le faʻasaoina o le fou ma le faʻasaoina umi o mea faʻapipiʻi, lea e faigofie mo le felauaiga ma le teuina.O mea faʻapipiʻi masini o se masini pe a uma ona tuʻuina le oloa i totonu o le atigipusa pusa, faʻafefe le ea i totonu o le atigipusa, e oʻo atu i se tikeri vacuum faʻatulagaina (e masani lava ile 2000 ~ 2500Pa) ma faʻamaeʻaina le faʻamau.E mafai foʻi ona faʻatumu i le nitrogen poʻo isi kasa fefiloi, ona faʻamaeʻa lea o le faʻamaufaʻailoga.
Talu mai le 1940s, ua fa'aalia ma fa'aogaina tekinolosi fa'apipi'i masini.Seia oʻo i le ogatotonu i le tuai o le 50 tausaga, na amata faʻasolosolo ona faʻaogaina e le vacuum packaging field le polyethylene ma isi ata palasitika mo le afifiina.I le amataga o le 1980s, faʻatasi ai ma le televave o le atinaʻeina o pisinisi faʻatau ma le faʻasolosolo malie o le faʻapipiʻiina o tamaʻi afifi, na faʻaaogaina ma atinaʻe le tekonolosi.E fetaui lelei le afifiina o masini mo le tele o pusa palasitika faʻapipiʻi poʻo le alumini pepa faʻapipiʻi ata tifaga, e pei o le polyester / polyethylene, nylon / polyethylene, polypropylene / polyethylene, polyester / alumini pepa / polyethylene, nylon / alumini pepa / polyethylene, ma isi mea.Faatasi ai ma le faʻaauau pea o le faʻaleleia atili o le faʻalauiloaina o manatu o tagata, o le faʻaogaina o masini faʻapipiʻi gaogao ua tosina mai ai le tele ma sili atu le gauai mai pisinisi e pei o meaʻai, ie, ma mea tau eletise.
Fa'avae ma le fa'avasegaina o masini fa'apipi'i gaogao
O le fausaga o masini faʻapipiʻi masini e ese, ma o le faʻavasegaina o auala e ese foi.E masani lava e tusa ai ma auala eseese afifiina, e mafai ona vaevaeina i masini extrusion ituaiga, intubation ituaiga, potu ituaiga, ma isi;e tusa ai ma le auala e ulu atu ai mea afifi i totonu o le potu, e mafai ona vaevaeina i le potu tasi, potu lua, thermoforming ituaiga, conveyor belt ituaiga, ma rotary potu gaogao.E tusa ai ma le ituaiga o gaioiga, e mafai ona vaevaeina i le vavao ma faʻaauau;e tusa ai ma le sootaga i le va o le oloa afifiina ma le atigipusa atigipusa, e mafai ona vaevaeina i le paʻu paʻu gaogao afifiina ma le afifiina inflatable.
Faʻatasi ai ma le faʻaauauina o le atinaʻeina o saienisi ma tekinolosi ma le faʻaauauina pea o le faʻaleleia o tulaga o le ola o tagata, o le faʻaaogaina o masini faʻapipiʻi masini o le a sili atu ma sili atu ona lautele, ma o le ituaiga, sitaili, faʻatinoga, ma le lelei o mea faʻapipiʻi masini o le a suia ma faʻaleleia.I totonu o pisinisi ie ma mea taulima, e mafai ona faʻaititia lelei le tele o oloa ma faʻafaigofie le afifiina ma felauaiga;i le alamanuia o mea'ai, fa'apipi'i gaogao ma tekinolosi fa'ama'i e mafai ona fa'agata lelei le fa'atupuina o siama, fa'agesegese le fa'aleagaina o mea'ai, ma fa'atuputeleina le fa'aola o mea'ai;i mea faaeletonika, I totonu o le alamanuia meafaigaluega, masini masini masini masini e mafai ona vavaeeseina le okesene, ina ia le oxidize ma elea mea fa'aoga.
