PET strap (polyester strap) erina obulamu obulagirwa okutereka obw’emyezi 18–36 mu mbeera entuufu. Ebbugumu, obunnyogovu, okubeera mu UV, n’obulungi bw’okupakinga byonna bikwata ku bbanga PET strap ly’ekuumamu omulimu gwayo.

Ebipimo by’omusingi bye bimu ku bisinga okubuusibwa amaaso ng’abaguzi balonze omusipi gwa PET (polyester strap) okukola emirimu gy’okusiba mu ngeri ey’otoma. Omusipi ogutuukana n’ebyetaago byonna eby’ebyuma —obugazi obutuufu, obuwanvu, n’amaanyi g’okumenya —gukyajja kuleeta obuzibu mu kuliisa singa obunene bwakyo obw’omusingi tebukwatagana na kigaba omutwe gw’omusipi. Core inner diameter, roll width, ne roll outside diameter byonna birina okukwatagana n’enkola ya spindle n’okusumulula ekyuma. Ekitabo kino kinnyonnyola ebipimo by’omusingi gw’omusipi gwa PET, engeri gye bikosaamu omulimu gw’omutwe gw’omusipi ogw’otoma, n’engeri y’okukakasa okukwatagana nga tonnagula.

Amaanyi g’okusika kw’omusipi gwa PET mu bujjuvu gava ku kkiro 160 okutuuka ku 635, okusinziira ku bipimo byakyo n’omutindo gw’okukola. Ekipimo kino kikiikirira amaanyi agasinga obunene omusipi gwa polyethylene terephthalate gwe gusobola okugumira nga tegunnamenya, ekigufuula ensonga enkulu eri mana y’okugula

Okukwataganya omusipi gwa PET n’ekyuma kyo eky’okusiba mu ngeri ey’otoma kyetaagisa okufaayo ku bugazi, obuwanvu, sayizi y’omusingi, n’okumaliriza kungulu. Ekitabo kino kikwata ku nsonga enkulu ezikwatagana, ensonga eza bulijjo, n’obukodyo bw’okulonda okukakasa nti ekola bulungi n’obukuumi bw’emigugu obwesigika.
