Iyo firimu yakatambanudzwa inoumba yakanyanya kujeka kuchengetedza kutaridzika kwakatenderedza chigadzirwa, uye yekutanga kugadzirisa inopa kutaridzika kwekugadzirisa kwechigadzirwa. Kuti uwane chinangwa chekudzivirira guruva, mafuta-uchapupu, hunyoro-uchapupu, husina mvura uye hunopesana nembavha, iyo inonyanya kukosha yakatambanudzwa firimu packaging inoita kuti zvinhu zvakaputirwa zvisimbiswe uye zvinodzivirira kusaenzana kwesimba kubva mukukuvadza zvinhu. Izvi hazvisizvo nekurongedza, kurongedza, tepi uye kumwe kurongedza. Zvakazviita.
Parizvino, iyo firimu yakatambanudza inoshandiswa zvakanyanya munzvimbo dzakasiyana. Iyo firimu yakatambanudzwa inogadzirwa neatatu-layer co-extrusion casting process, uye inotengeswa kunze mutsara yakaderera-density polyethylene inoshandiswa seyakanyanya mbishi zvinhu. Izvo zvakasiyana-siyana zvehunyanzvi zviratidzo zvechigadzirwa zvasvika kune inotungamira nhanho yepasirese, uye zvine zvakanakira zveunifomu firimu roll, yakanaka tensile kuita, kudzoreredza kwakasimba, kujeka kwepamusoro, simba rekubvarura uye kuzvinamira patembiricha yekamuri. Ukobvu hwefirimu hunotemwa kubva pa15μm kusvika 50μm uye hupamhi kubva pa5cm kusvika 100cm. Kunamira kwakakamurwa kuita-sided sticking uye kaviri-side sticking. Inoshandiswa zvakanyanya mukurongedza kurongedza uye akasiyana pallet kurongedza mune zvekuvaka, makemikari, girazi, ceramics, zvemagetsi, simbi, auto zvikamu, waya, bepa, canning, zvinodikanwa zvezuva nezuva, chikafu uye mamwe maindasitiri, kuitira kuti uwane hunyoro-huchapupu, guruva- humbowo, kuderedza basa nekuvandudza kushanda zvakanaka Uye mhedzisiro yekudzikisa mari.
Stretch film packaging inoita kuti chinyorwa chiite compact unit isingatore nzvimbo. Chigadzirwa chacho chakaputirwa uye chakaputirwa nerubatsiro rwekudzorera simba refirimu yakatambanudzwa. Zvigadzirwa zvematireyi zvakaputirwa zvakasimba pamwe chete, izvo zvinogona kudzivirira zvinobudirira zvigadzirwa kubva pakukanganisa uye kufamba panguva yekufambisa. Iyo firimu inotambanuka inogona kutambanudzwa nepo iyo inogadziriswa inotambanudza simba inogona kuita kuti zvigadzirwa zvakaoma zvinyatso kunamatira kune zvakapfava zvigadzirwa, kunyanya Iyo yakasarudzika yekurongedza mhedzisiro muindasitiri yefodya uye indasitiri yemachira.
Inogona kunyatso kudzikisa mutengo wekushandisa, uchishandisa yakatambanudzwa firimu rekurongedza chigadzirwa. Iko kushandiswa kwefirimu yakatambanudzwa inongova 15% yepakutanga bhokisi kurongedza, inenge 35% yefirimu inopisa inopisa, uye inenge 50% yebhokisi rebhokisi. Panguva imwecheteyo, inogona kuderedza kusimba kwevashandi, kuvandudza kugona kwekurongedza uye kunaka kwekurongedza.
