Umnatha ochasene nezilwanyana owenziwe nge-polyethylene awunavumba, ukhuselekile, awunatyhefu kwaye uguquguquka kakhulu.Ubomi be-HDPE bunokufikelela kwiminyaka engaphezu kwe-5, kwaye ixabiso liphantsi.
Iminatha ekhusela izilwanyana kunye nentaka ingasetyenziselwa ukukhusela iidiliya, i-cherries, imithi yamapere, ama-apile, i-wolfberry, ukuzala, i-kiwifruit, njl njl. Ukukhusela iidiliya, abalimi abaninzi bacinga ukuba kuyimfuneko.Ngeediliya kwi-shelf, inokugqunywa ngokupheleleyo, kwaye kufaneleka ngakumbi ukusebenzisa isilwanyana esinamandla kunye nenetha yeentaka, kwaye ukukhawuleza kubhetele ngakumbi.Iminatha yezilwanyana ikhusela izityalo ekonakalisweni kwizilwanyana zasendle ezahlukeneyo kwaye ziqinisekisa isivuno.Isetyenziswa kakhulu kwimarike yaseJapan.
