Ese marudzi emabhegi, mabhokisi, seti nemahamvuropu akagadzirwa nepepa, aluminium foil, faibha, firimu repurasitiki uye macomplexes avo anochinjika kurongedza. Kazhinji, mapepa epurasitiki ane ukobvu husingasviki 0.25mm anonzi mafirimu. Firimu yepurasitiki yakajeka, inoshanduka, ine mvura yakanaka yekudzivirira, kunyorova uye kusagadzikana kwemhepo, simba rakanaka remagetsi, kugadzikana kwemakemikari zvinhu, mafuta anopikisa, nyore kudhinda zvinyorwa zvakanaka, zvinogona kupisa chisimbiso bhegi. Inogona kusangana nezvinodiwa zvekurongedza zvemarudzi ese ezvinhu, inoshandiswa mukutakura zviri nyore kuchengeta, zviri nyore kuisa chikafu chiri nyore, zvinodikanwa zvezuva nezuva, supermarket diki pasuru zvinhu zvakanaka zvinhu.
