Kutentha shrink phukusi filimu, yomwe imadziwikanso kuti filimu yotentha ya PE, ndi yosunthika komanso yogwiritsidwa ntchito kwambiri popanga ma CD.Ndi mtundu wa filimu ya pulasitiki yomwe imachepa pamene kutentha kumagwiritsidwa ntchito, kupanga kukulunga kolimba ndi kotetezeka mozungulira chinthu chomwe chikuphimba.Njirayi imagwiritsidwa ntchito ponyamula zinthu zambiri, kuchokera ku chakudya ndi zakumwa kupita kumagetsi ndi zinthu zogula.M'nkhaniyi, tiwona momwe filimu yochepetsera kutentha imagwirira ntchito komanso ntchito zake zosiyanasiyana pamakampani opanga ma CD.
Njira ya filimu yochepetsera kutentha imaphatikizapo kugwiritsa ntchito makina apadera ochepetsera kutentha kapena mfuti yamoto kuti agwiritse ntchito kutentha kwa filimuyo.Firimuyi imakulungidwa koyamba ndi chinthu kapena chinthu chomwe chiyenera kuikidwa, ndiyeno kutentha kumayikidwa pafilimuyo.Pamene filimuyo imatenthedwa, imayamba kuchepa ndikugwirizana ndi mawonekedwe a mankhwala, kupanga chisindikizo cholimba komanso chotetezeka.Njirayi sikuti imangopereka chitetezo komanso kukana kusokoneza komanso imapangitsanso chidwi cha zinthu zomwe zapakidwa.
Chinsinsi chakuchita bwino kwafilimu yochepetsera kutenthazagona mu kapangidwe kake.Kanema wonyezimira wa PE nthawi zambiri amapangidwa kuchokera ku polyethylene, mtundu wa polima wa thermoplastic womwe umakhala wofewa komanso wofewa ukatenthedwa.Izi zimathandiza kuti filimuyo iwonongeke ndikugwirizana ndi mawonekedwe a mankhwalawo, kupanga chophimba chokwanira komanso choteteza.Kuphatikiza apo, filimuyo imathanso kukhala ndi zowonjezera monga UV inhibitors ndi anti-static properties kuti ipititse patsogolo magwiridwe ake komanso kulimba kwake.
Ubwino waukulu wa filimu yochepetsera kutentha ndi kusinthasintha kwake komanso kusinthika kwamitundu yosiyanasiyana ndi makulidwe azinthu.Kaya amagwiritsidwa ntchito kuyika zinthu payekha kapena kupanga mapaketi angapo,filimu yochepetsera kutenthazitha kusinthidwa kuti zigwirizane ndi zinthu zambiri.Izi zimapangitsa kukhala njira yabwino yopangira mafakitole osiyanasiyana, kuphatikiza zakudya ndi zakumwa, mankhwala, zodzoladzola, ndi zogulitsa.
M'makampani azakudya ndi zakumwa, filimu yochepetsera kutentha imagwiritsidwa ntchito popanga zinthu monga mabotolo, zitini, ndi mathireyi.Firimuyi imapereka chisindikizo chotetezeka komanso chosokoneza, kuonetsetsa chitetezo ndi kukhulupirika kwa katundu wopakidwa.Kuonjezera apo, filimu yochepetsera kutentha imathanso kusindikizidwa ndi chidziwitso cha malonda ndi malonda, kukhala ngati chida chamalonda chokopa ogula.
M'makampani ogulitsa, filimu yochepetsera kutentha imagwiritsidwa ntchito pomanga zinthu pamodzi, kupanga zowonetsera zokongola komanso zokonzedwa bwino.Kaya imagwiritsidwa ntchito kuyika zoseweretsa, zamagetsi, kapena zinthu zapakhomo, filimu yochepetsera kutentha imathandizira kuteteza zinthuzo kuti zisawonongeke ndi kubedwa ndikuwonjezera kukopa kwawo pamashelefu.
Kuphatikiza apo, filimu yochepetsera kutentha imagwiritsidwanso ntchito m'mafakitale ndi zida zogwirira ntchito pogwirizanitsa ndikusunga katundu wokhazikika.Ndi kukulunga pallets ndi kutentha shrink filimu, mankhwala amatetezedwa ku fumbi, chinyezi, ndi kuwonongeka pa mayendedwe ndi kusunga.
Pomaliza, filimu yosungiramo kutentha, monga filimu yowotcha kutentha kwa PE, ndi yogwira ntchito kwambiri komanso yosunthika yomwe imapereka maubwino angapo, kuphatikiza chitetezo, kukana kusokoneza, komanso kukopa kowoneka.Kutha kwake kutengera mawonekedwe azinthu komanso kusinthika kwake kumafakitale osiyanasiyana kumapangitsa kuti ikhale chisankho chodziwika bwino pakuyika mayankho.Kaya imagwiritsidwa ntchito pazinthu zamtundu uliwonse, mapaketi angapo, kapena zonyamula palletized, filimu yochepetsera kutentha imakhala ndi gawo lofunikira pakuwonetsetsa chitetezo ndi kukhulupirika kwa katundu wopakidwa.
