Ogwira ntchito ku American Chemical Society apanga ma eco-friendly package kuti asunge zinthu zosiyanasiyana. Zimachokera ku filimu yopangidwa ndi casein, yomwe ndi gawo la mkaka. Puloteniyi imapezeka chifukwa cha kutsekemera kwakumwa.
Zinthu Zakuthupi
Zowoneka, zakuthupi sizosiyana ndi polyethylene yofala. Mbali yaikulu ya phukusi latsopanoli ndikuti ikhoza kudyedwa. Chogulitsacho sichiyenera kuchotsedwa ku phukusi kuti chikonzekere, popeza zinthuzo zimasungunuka kwathunthu pa kutentha kwakukulu.
Madivelopa amanena kuti kulongedza kwake kulibe vuto lililonse kwa thupi la munthu komanso chilengedwe. Masiku ano, chakudya chambiri chimapangidwa kuchokera kumafuta amafuta. Pa nthawi yomweyi, nthawi yowonongeka kwa zinthu zoterezi ndi yaitali kwambiri. Mwachitsanzo, polyethylene imatha kuwola mkati mwa zaka 100-200!
Mafilimu opangidwa ndi mapuloteni salola kuti mamolekyu a okosijeni afikire chakudya, kotero kuti zotengerazo zimateteza zinthu kuti zisawonongeke. Chifukwa cha mafilimuwa, malinga ndi omwe amapanga zinthu zatsopanozi, zidzatheka kuchepetsa kwambiri zinyalala zapakhomo. Kuphatikiza apo, zinthu zapaderazi zimatha kupangitsa chakudya kukoma bwino. Mwachitsanzo, chimanga chokoma cham'mawa chidzapeza kukoma kwakukulu kuchokera mufilimuyi. Ubwino wina wa mapaketi oterowo ndi liwiro la kuphika. Mwachitsanzo, msuzi wa ufa ukhoza kuponyedwa m'madzi otentha pamodzi ndi thumba.
Kukulaku kudawonetsedwa koyamba pachiwonetsero cha 252nd ACS. Zikuyembekezeka kuti nkhaniyi ipeza ntchito m'mafakitale angapo posachedwa. Pakukhazikitsa, ndikofunikira kuti ukadaulo wopanga mapaketi oterowo ukhale wopindulitsa pazachuma. Komabe, poyambira, nkhaniyi iyenera kuwunikiranso mozama ndi United States Food and Drug Administration. Oyang'anira ayenera kutsimikizira chitetezo cha kugwiritsa ntchito zinthu pazakudya.
Zotsatsa zina
Asayansi akuwona kuti ili si lingaliro loyamba kupanga zotengera zodyedwa. Komabe, teknoloji yopangira zinthu zoterezi pakali pano si yangwiro. Kotero, panali kuyesa kupanga ma CD a chakudya kuchokera ku wowuma. Komabe, zinthu zotere zimakhala ndi porous, zomwe zimapangitsa kuti mpweya ulowe m'mabowo ang'onoang'ono. Chifukwa cha zimenezi, chakudya chimasungidwa kwa kanthaŵi kochepa chabe. Mapuloteni amkaka alibe pores, omwe amalola kusungirako nthawi yayitali.
