Fomu Liner ndeye-chidimbu-liner, zvinhu zvacho EVA, EPE nezvimwe.
Pachayo elastic tumira contractility uye mudziyo chiteshi.
Inokodzera marudzi ese emidziyo yekuvharisa, inogona kushandiswa kakawanda, asi chisimbiso mhedzisiro ndeyese.
Inogona kushandiswa mushure uye aluminium-plastiki inoumba membrane inoumbwa uye yekuisa chisimbiso iri nani.
Iwo makuru maficha ekuchena, guruva, usatora mhute yemvura, kwete nekuda kwehunyoro kana tembiricha kuti ichinje kugadzikana kwayo.
