Filime ya Stretch, izwi kandi nka firime yo kurambura no kugabanya ubushyuhe bwa firime, yakozwe bwa mbere mu Bushinwa ikoresheje PVC nk'ibikoresho fatizo na DOA nk'ibikoresho bya pulasitiki ndetse no kwizirika kuri firime ya PVC. Kubera ibibazo by’ibidukikije, igiciro kinini (ugereranije na PE, ahantu hapakirwa kuri buri gice) no kutaguka neza, PE kurambura filime byahagaritswe igihe umusaruro wimbere mu gihugu watangiraga muri 1994-1995. Ibikoresho fatizo ni LLDPE, harimo C4, C6, C8 na metallocene PE (MPE).
Ibice
Ikorwa hifashishijwe resin ya LLDPE itumizwa mu mahanga hamwe na tackifier idasanzwe yongeweho, kandi irashobora gukora firime yimikorere myinshi kumaboko, imashini yubwoko bwimashini, imashini yabanjirije kurambura, anti-UV, anti-static na anti-rust. Ifite ibyiza bikurikira:
1. Ukoresheje ibikoresho bibiri-bifatanyiriza hamwe, firime ikanda irashobora guhinduranya cyane ibiranga buri polymer, gukorera mu mucyo, imbaraga zikaze, hamwe no guhangana na perforasi, bikagera kumurongo mwiza aho ushonga.
2. Ifite imiterere myiza ya tensile, gukorera mu mucyo, n'ubugari bumwe.
3. Ifite uburebure burebure, kwihangana neza, kurwanya amarira meza ya horizontal, hamwe no kwizirika neza.
4. Nibidukikije byangiza ibidukikije byongera gukoreshwa, bitaryoshye, bidafite uburozi, birashobora gupakirwa ibiryo.
5. irashobora gukora ibicuruzwa bifata uruhande rumwe, kugabanya urusaku rwatanzwe mugihe cyo guhinduranya no kurambura, kugabanya ivumbi n'umucanga mugihe cyo gutwara no kubika.
Gusaba
1. Gupakira
Ubu bwoko bwo gupakira busa no kugabanya ibipfunyika bya firime, aho firime izengurutswe na pallet kugirango uyizenguruke, hanyuma ubushyuhe bubiri bwo gufata ubushyuhe bufunga firime kumpande zombi hamwe. Ubu ni bwo buryo bwa mbere bwo gupfunyika firime yakoreshejwe kandi biganisha ku iterambere ryuburyo bwinshi bwo gupakira
2. Ububiko bwuzuye
Ubu bwoko bwo gupakira busaba firime kuba yagutse bihagije kugirango itwikire pallet, ifite imiterere isanzwe, kuburyo ikwiriye gukoreshwa hamwe nubunini bwa firime ifite uburebure bwa 17 kugeza 35 mm.
3.Gupakira intoki
Ubu bwoko bwo gupakira nubwoko bworoshye bwo gupfunyika firime, firime yashizwe kumugozi cyangwa kubiganza, ukoresheje pallet kuzunguruka cyangwa firime ikikije pallet. Ikoreshwa cyane mugusubiramo pallet zipfunyitse nyuma yo kumeneka, hamwe no gupakira pallet isanzwe. Ubu bwoko bwo gupakira buratinda kandi uburebure bwa firime bukwiye ni 15 kugeza kuri 20 mm.
