Umunyamuryango wibyuma, umuyoboro urekuye umugozi hamwe na aluminiyumu kaseti yimbere hamwe nicyuma cyuma cyuma cyuma cya PE (GYTA53) Wasin Fujikura

Fibre ishyizwe mubijumba bidoze bikozwe muri plastiki ndende. Imiyoboro yuzuyemo ibice bifunga amazi. Umugozi wibyuma, ushyizwe hamwe na polyethylene nibiba ngombwa, uherereye hagati yibanze nkumunyamuryango wimbaraga. Imiyoboro ihagaze hafi yimbaraga kugirango ikore insinga ya kabili. Ikariso ya aluminiyumu ikoreshwa hafi ya caoble, yuzuyemo uruganda rwuzuye kugirango irinde amazi. Polyethylene ya layer isohoka nk'icyatsi cy'imbere. Nyuma ya PSP imaze igihe kinini ishyizwe hejuru yimbere yimbere, umugozi wuzuye hamwe na PE yo hanze.
