Mayelana nemikhiqizo yokubumba sinezinhlobo ezimbili zemikhiqizo, okungamakepisi okuphela kwekhebula ashwabanisa ukushisa kanye nokunqamuka kwekhebula elishwabanisa ukushisa. Ikhebula lokugcina ikhebula lokunciphisa ukushisa libunjwe ngomjovo nge-polyolefin futhi linokumelana ne-UV nokuhuzuka. Ingcina yokuncibilika eshisayo inamekwe ngendlela ezungezayo ngaphakathi kweshubhu, ihlinzeka ngokuvikeleka okuthembekile kokuvikela amanzi kanye nokuvala indawo enqunyiwe yezintambo noma izintambo ezigcwele umoya. Ukukhishwa kwe-heat shrink, okwenziwe ngezinto ezincibilikayo ezishisayo kanye nongqimba lwe-polyolefin exhunywe ngokuphambana, futhi kunokusebenza okuhle kakhulu kokuvala, ukuvikela kusetshenziswa kakhulu ekufakeni nasekuvaleni egatsheni lekhebula lamandla kagesi ophansi.
