Izvo zvigadzirwa zvematanda ekunze ekunze zvinonyanya kukamurwa kuita misasa miviri: polyethylene (pe) uye polyvinyl chloride (PVC).
Polyethylene (pe): Inoita urege kukwirira, kupfeka kurwisa, kukanda kupokana, uye kupokana kukuru. Iyo zvakare ine yakanakisa yemagetsi yekunzwa uye kugadzirisa zvivakwa. Naizvozvo, kana tambo dzifumurwa nemhepo, senge mumatanda kana mabhiriji apo murazvo restardurncy inodikanwa, tinokurudzira kushandisa polyvinyl chloride yakacheneswa tambo.
Polyvinyl Chloride (PVC): iyo sheati pachahwo {{0} yekudzima zvivakwa, murazvo wakanakisa kudzoreredza, mutengo wakaderera uye nekuchinjika kwakanaka. Naizvozvo, kana tambo dzakarongwa, dzakavigwa zvakananga pasi pevhu, hwakazadzwa nejecha trenches, kana apo pasi pevhu rakakwira uye dzaigara dzichinyungudika, tinokurudzira kusarudza polyety tambo!
