Foam liner ndi wamba, wopangidwa ndi thovu la polyethylene.Izi sizimapanga chisindikizo, ndipo nthawi zambiri zimagwiritsidwa ntchito popewa kutulutsa.
Fomu Liner ndi chingwe chimodzi, zinthuzo ndi EVA, EPE etc.
Payokha zotanuka tumizani contractility ndi chidebe doko.
Oyenera mitundu yonse ya kusindikiza chidebe, angagwiritsidwe ntchito mobwerezabwereza, koma chisindikizo zotsatira zambiri.
Itha kugwiritsidwa ntchito pambuyo ndi aluminium-pulasitiki yophatikizika nembanemba ndipo kusindikiza kwake kuli bwino.
Mbali zazikulu za ukhondo, fumbi, musatenge nthunzi wa madzi, osati chifukwa cha chinyezi kapena kutentha kusintha kukhazikika kwake.
