Izikhwama ze-Flat-Bottom ziwuhlobo oluhlukile lwesikhwama esinamaphaneli amahlanu endawo ephrintekayo yokwakhiwa komkhiqizo eshalofini. Indlela isikhwama esibonisa ngayo umkhiqizo iphrojekthi yesithombe sekhwalithi ephezulu. Futhi idizayini ehlukile yezikhwama eziphansi eziyisicaba inikeza ukuzinza okuphakeme, amandla ophawu, kanye ne-hermeticity uma kuqhathaniswa nezinye izinhlobo zezikhwama eziphansi eziphansi.
"Kalula nje, isikhwama esiphansi esiphansi siyisikhwama esinezinhlangothi ezinhlanu, esikhululekile esinesisekelo esiyisicaba, esiwunxande. Sinezinto zesikhala esikhulu namandla, okwaziwa ngokuthi ama-gussets, ohlangothini lwesokunxele nolwesokudla lwesikhwama, nge-fastener phezulu.
Izikhwama eziningi eziphansi eziyisicaba zenziwe nge-kraft paper, i-aluminium, noma i-LDPE. Ezinye zizohlanganisa izendlalelo ezimbili noma ngaphezulu ukuze kuvikeleke okwengeziwe noma izinjongo zobuhle.
Isibonelo, abashisi bekhofi abafuna ukuxhumana nokubukeka kwe-rustic bangase bakhethe iphepha le-kraft ngaphandle eline-aluminium foil yangaphakathi, isithiyo esisebenzayo ngokumelene nokukhanya, umswakama, nomoya-mpilo.
Izishicileli zekhofi ezikhethekile zingaphinda zikhethe ukufaka izici ezengeziwe ukuze kwandiswe ukusha nephunga elimnandi, njengamaziphu aphinde avaleleke noma amavalvu asusa umoya.
Ngenxa yokuhlukahluka kwazo kanye nezindawo ezinkulu eziphrintekayo, izikhwama eziphansi eziyisicaba zidumile phakathi kwalezo ezinophawu oluqinile lomkhiqizo. Zingenziwa ngendlela oyifisayo ngemibala ehlukene, imibala, nemiklamo, engasiza abarosayo baxhumane namakhasimende."
"Isakhiwo esiqinile nesiqinile esithwala umthamo womkhiqizo owengeziwe kuyilapho sihlala sikhanga ngokubonakalayo eshalofini
Isikhwama esiphansi esiyisicaba sinikeza ukwesekwa okwengeziwe ukuze kube lula ukugcina lapho upakisha umkhiqizo wakho. Ama-quad-seal, ama-side-gussets kanye nephansi eliyisicaba kunikeza ukuqina kanye nevolumu yokugcwalisa ngaphezulu kunezinye izikhwama zokupakisha eziguquguqukayo. Izikhwama eziphansi eziphansi ziyinketho ethandwayo ezimbonini eziningi ezihlukahlukene ngenxa yekhono lazo lokubamba inani elikhulu lomkhiqizo ngokwesisindo kanye nevolumu ngenkathi zisalokhu zibukeka zikhanga eshalofini. Sisebenzisa kuphela izinto zekhwalithi ephezulu kakhulu ezinweba impilo yeshalofu futhi zivumele okuqukethwe kwesikhwama ukuthi kuhlale kusha isikhathi eside. Ngokungeza i-zip edizayini yakho ephansi eyisicaba, ungagcina ubuqotho bemikhiqizo yakho kuyilapho unikeza inketho yomkhiqizo wokuphakelwa okuningi."
