Gufata inshundura nshyashya net yarangije gupakira uyumunsi

Uruzitiro rwa bale rukozwe muri 100% HDPE (Polyethylene yuzuye cyane), kandi ikwiriye gupfunyika ibyatsi byatsi. Uruzitiro rwa neti rushobora kubika igihe cyo gupfunyika imipira, kandi imipira yarangiye irashobora gushyirwa hasi. Biroroshye gutemwa no gukurwaho, birashobora kandi kuzamura cyane ubwiza bwibyatsi kandi bigahinduka ubundi buryo bushimishije bwimpanga zo gupfunyika ibyatsi. Gukoresha inshundura bitezimbere cyane umusaruro kuko bisaba igihe gito cyo gupfunyika bale. Bizagutwara igihe kirenze 50%. Urushundura rugufasha gukora neza kandi neza - imipira imeze byoroshye kwimuka no kubika.
