Kutentha wamba shrinkable filimu zipangizo akhoza pafupifupi kugawidwa mu mitundu isanu: POF, Pe, PET, PVC, OPS. Kodi pali kusiyana kotani pakati pawo?

Kanema wa POF nthawi zambiri amagwiritsidwa ntchito popaka zakudya zina zolimba ndipo nthawi zambiri amatenga njira yosindikizira yosindikizidwa. Mwachitsanzo, tikuwona kuti Zakudyazi ndi tiyi wamkaka zonse zili ndi zinthu izi. Chigawo chapakati chimapangidwa ndi polyethylene yotsika kwambiri (LLDPE), ndipo zigawo zamkati ndi zakunja zimapangidwa ndi polypropylene ya copolymerized (pp). Ndi plasticized ndi extruder ndi extruders atatu ndiyeno kukonzedwa ndi njira yapadera monga nkhungu kupanga ndi filimu kuwira inflation.

Makhalidwe a filimu ya polyester yotentha ya PET: yokhazikika kutentha kwa firiji, kutentha kwa kutentha (pamwamba pa kutentha kwa galasi), ndi njira imodzi kutentha kumachepera kuposa 70%. Ubwino wa kuyika kwa filimu ya polyester yowotcha kutentha ndi: mvula, chinyezi, chinyezi, mildew-proof; zosabweza, ndipo zimakhala ndi ntchito inayake yolimbana ndi chinyengo. Kanema wa polyester wotentha wa PET nthawi zambiri amagwiritsidwa ntchito muzakumwa, mkaka, zakudya zosavuta, zida zina zamagetsi, ndi zinthu zachitsulo, makamaka zilembo zocheperako ndizomwe zimafunikira kwambiri.

Kanema wa PVC ali ndi mawonekedwe owonekera kwambiri, gloss wabwino ndi kuchepa kwakukulu;

OPS shrink film (oriented polystyrene) kutentha shrinkable film ndi mtundu watsopano wa ops kutentha shrinkable filimu ma CD zinthu zimene zimakwaniritsa zofunika kuteteza chilengedwe. OPS kutentha shrinkable filimu ali ndi makhalidwe a mphamvu mkulu, mkulu kukhazikika, mawonekedwe okhazikika, gloss wabwino ndi kuwonekera. Zosavuta kukonza, zosavuta kuziyika, zosindikiza bwino, kusindikiza kwakukulu. Ndikudumpha kwabwino kwa zilembo zomwe zimakonda kusindikiza kosangalatsa nthawi zonse. Chifukwa cha kuchuluka kwa shrinkage komanso mphamvu yayikulu ya filimu ya OPS, imatha kulumikizidwa kwambiri ndi makontena amitundu yosiyanasiyana, kotero kuti sichitha kungosindikiza mawonekedwe okongola, komanso kukumana ndi kugwiritsa ntchito zida zonyamula zamitundu yosiyanasiyana. Kanemayu wopanda poizoni, wopanda fungo, wosamva fungo lamafuta yemwe amakwaniritsa miyezo yaukhondo yazakudya amalola opanga kupanga mapangidwe a zilembo za 360° pogwiritsa ntchito mitundu yokopa maso.

PEKutentha shrinkable filimu chimagwiritsidwa ntchito kwambiri ma CD ophatikizika ndi masango ma CD mowa, zakumwa, madzi a m'mabotolo, mchere madzi.

PE kutentha shrinkable filimu ali kusinthasintha zabwino, kukana amphamvu amakhudza, amphamvu kukana misozi, si kosavuta kuthyola, mkulu shrinkage mlingo, kuteteza mankhwala zokala, ndi yabwino mayendedwe; imateteza mvula, imateteza chinyezi, komanso imateteza mildew; nthawi yomweyo, angagwiritsidwe ntchito pa PE kutentha shrinkable filimu Kuchita malonda, wapamtima ndi mandala, kusonyeza mankhwala fano, ndi bwino kulimbikitsa malonda malonda;

Kugwiritsa ntchito filimu yotenthetsera kutentha kwa PE pamsika wazakudya zamadzimadzi, makamaka makampani a zakumwa, ndikusintha kwa msika. Kutentha shrinkable filimu makamaka m'malo mwa miyambo katoni ma CD, katoni + filimu thumba, monga pepala anathandiza filimu thumba, makatoni filimu thumba, koyera filimu ma CD ma CD ndi zambiri ndi ambiri;

Chifukwa ndi kukula mofulumira kwaMabotolo a zakumwa za PET, madzi a zipatso ndi zakumwa za tiyi wa zitsamba zonse zimagwiritsa ntchitoMabotolo a zakumwa za PET, ndi ntchito PE kutentha shrinkable filimu kwa sekondalekuyika;

PE kutentha shrinkable filimu ndi poliyesitala ndipo ndi zinthu zachilengedwe wochezeka. kunyozeka.
