Nyuma yincamake ya firime ya BOPP, ufite kutumva neza ibi bikoresho biboneka hose? Muri iyi blog, tuzarushaho gushishoza kubyiza n'ibibi, bityo turusheho kwibanda kubyo abakiriya bakeneye.
Niki BOPP Film
Filime ya Biaxically Orient Polypropylene (BOPP) yahinduye inganda zipakira kuva yatangira mu myaka ya za 70. Ibi bikoresho bishya, birambuye muburyo bwa tekinike ndetse nintoki ukoresheje tekinoroji yambukiranya icyerekezo, bitanga ihuza ryihariye ryimitungo yatumye iba ingenzi mubikorwa bitandukanye.
Ibintu by'ingenzi biranga BOPP
idafite ibara kandi idafite impumuro nziza Kamere
uburozi Ibigize
Kuringaniza gukomera no gukomera
zitangaje Kurwanya ingaruka
zingana cyane Imbaraga (indangagaciro zisanzwe ziri hagati ya 130-300 MPa)
bidasanzwe Gukorera mu mucyo (kugeza 90% byohereza urumuri)
Iyi mitungo yashyize BOPP nkibikoresho bitandukanye mu nganda nyinshi, kuva mubipfunyika ibiryo kugeza kumyenda.
Ibyiza bya BOPP
Ibintu bifatika
BOPP irusha imbaraga imbaraga nigihe kirekire, hamwe nimbaraga zingana zishobora kugera kuri MPa 300 mu cyerekezo cyimashini. Kugaragara kwayo neza, hamwe nigipimo cyo kohereza urumuri rugera kuri 90%, byongera ibicuruzwa kugaragara mububiko. Ihagarikwa rya firime ryerekana imikorere ihamye mubikorwa bitandukanye, hamwe nibisanzwe bigabanuka munsi ya 4% kuri 130 ° C.
Kurwanya gucumita no gucamo flex bituma BOPP iba nziza kubipakira. Kurugero, firime 20-micron ya BOPP irashobora kwihanganira kugera kuri 130 g / 25 μm mugupima ingaruka za dart, ikerekana imbaraga zayo mubikorwa nyabyo.
Ibikoresho bya Shimi
BOPP ikora nk'inzitizi ikomeye yo kurwanya ubushuhe ， umwanda, n'imiti yangiza. Igipimo cyayo cyohereza amazi (WVTR) gishobora kuba munsi ya 4-5 g / m² / kumunsi kuri 38 ° C na 90% ugereranije nubushuhe, bigatuma ihitamo neza kubicuruzwa bitita ku bushyuhe.
Amavuta ya firime hamwe namavuta arwanya, hamwe nibisanzwe birenga 7 kurwego rwo gupima Kit, bikomeza kwaguka gukoreshwa. Iyi mitungo ituma BOPP ihitamo neza kubipfunyika ibiryo no gukoresha inganda, aho kurinda ibicuruzwa aribyo byingenzi.
Inyungu zidukikije
Muri iyi si yita ku bidukikije, BOPP irabagirana hamwe n’ibidukikije:
Gusubiramo : BOPP igwa munsi ya code ya # 5 (PP), bigatuma ikoreshwa cyane.
Umucyo woroshye : Ubucucike busanzwe bugera kuri 0.90-0.92 g / cm³ bigira uruhare mu kugabanya ibyuka bihumanya ikirere.
Umusaruro ukoresha ingufu : Uburyo bwo gukora butwara ingufu nke ugereranije nibindi bikoresho.
Ubushakashatsi bwisuzuma ryubuzima bwakozwe n’ishyirahamwe ry’abakora amafilime y’iburayi ya Polypropilene bwerekanye ko filime ya BOPP ifite 40% munsi ya karuboni ikirenge ugereranije na firime PET ihwanye.
Inyungu mu bukungu
BOPP itanga inyungu zingirakamaro kubera umusaruro mwinshi. Ubucucike bwa hafi 0,90-0.92 g / cm³ bivamo firime nyinshi kuburemere bwikigereranyo ugereranije nubundi buryo nka polyester (ubucucike ~ 1,4 g / cm³). Ibi bisobanura kuzigama amafaranga mugukoresha ibikoresho no gutwara.
Kwakira kwisi byorohereza ubucuruzi mpuzamahanga no kohereza ibicuruzwa. Raporo y’inganda ivuga ko akarere ka Aziya-Pasifika kiganje ku isoko rya BOPP, bingana na 60% by’ubushobozi bw’umusaruro ku isi.

Ibibi bya BOPP
Ikibazo
Imiterere mibi ya BOPP irashobora kuba ikibazo mubikoresho bimwe byo gupakira. Ubushyuhe bwa kashe isanzwe iri hagati ya 200-400 g / 25 mm, iri munsi ugereranije na firime zindi. Iyi mbogamizi akenshi isaba ubundi buryo bwo kuvura cyangwa gutwikira kugirango tunonosore ibimenyetso, bishobora kongera umusaruro.
Ibibazo by'ingufu zo hejuru
Ingufu zo hasi (mubisanzwe 29-31 mN / m) zitera ibibazo muguhuza wino. Ibi bivamo ibisubizo byanditse neza, bikenera kuvurwa hejuru mbere yo gucapa. Kuvura Corona birashobora kongera ingufu zubutaka kuri 38-42 mN / m, ariko iyi ngaruka igabanuka mugihe.
Kamere ya Crystalline
Imiterere ya BOPP ihanitse cyane (mubisanzwe 60-70% ya kristu) irashobora gutera:
Ibi bibazo birashobora kugira ingaruka kumiterere ya firime no mubikorwa mubikorwa byihariye, cyane cyane aho optique isobanutse ari ngombwa.
Amashanyarazi ahamye
Umusaruro wihuse akenshi ubyara amashanyarazi ahamye muri firime ya BOPP, hamwe nuburwanya bushobora kugera kuri 10¹⁶ Ω / sq. Ibi birasaba gushyira mubikorwa uburyo bwo gukuraho static mugihe cyo gukora, wongeyeho ibintu bigoye hamwe nigiciro kumurongo wibyakozwe.
Porogaramu ya BOPP
Inganda zo gupakira
BOPP yiganje mu gupakira ibiryo bitewe ninzitizi nziza kandi nziza. Byakoreshejwe kuri:
Isoko rya firime zipakira ibiryo ku isi, ahanini ryayobowe na BOPP, ryahawe agaciro ka miliyari 37.5 z'amadolari muri 2020 bikaba biteganijwe ko miliyari 53.9 z'amadolari . mu 2026 rizagera kuri

Kaseti ifata (gufatisha igishishwa: 15-20 N / 25mm)
Gupakira indabyo (igipimo cyogukwirakwiza imyuka: 4-5 g / m² / kumunsi)
Ubwinshi bwayo bukomeje gufungura amasoko mashya, hamwe na BOPP ya firime yihariye ikura kuri CAGR ya 7.2%.
Gutezimbere no Guhindura
Kugira ngo utsinde imbogamizi, BOPP ikorerwa imiti itandukanye:
Kuvura Corona : Yongera ingufu zubutaka kuri 38-42 mN / m
Kuvura plasma : Kugera ku mbaraga zo hejuru zigera kuri 50 mN / m
Topcoatings : Itezimbere icapiro hamwe na kashe
Izi nzira zitezimbere guhuza hamwe nibikorwa muri rusange, hamwe na firime zavuwe zigaragaza iterambere rya 50% muguhuza wino.
