Mhedziso yekudhinda uye bhegi kugadzira kuita kwemhando nhanhatu dzepolypropylene mafirimu

1. UniversalBOPP firimu

BOPP firimu inzira umo maamorphous kana chikamu checrystalline mafirimu anotambanudzwa akatwasuka uye akatwasuka pamusoro penzvimbo yekupfava panguva yekugadziriswa, zvichikonzera kuwedzera kwenzvimbo, kudzikira kwehukobvu, uye nekunatsiridza kukuru mukupenya uye pachena. Panguva imwecheteyo, nekuda kwekutarisa kwemamorekuru anotambanudza, simba ravo remuchina, kusapinda kwemhepo, kupikisa hunyoro, uye kutonhora kwekudzivirira kwakagadziridzwa zvakanyanya.

Hunhu hweBOPP firimu:

High tensile simba uye elastic modulus, asi yakaderera kubvarura simba; Kuomarara kwakanaka, kureba kwakatanhamara uye kukotama kuneta kuramba; Kupisa kwakanyanya uye kutonhora kwekudzivirira, ine tembiricha yekushandisa inosvika 120. BOPP zvakare ine yakakwira kutonhora kupikisa kupfuura general PP mafirimu; Kupenya kwepamusoro uye kujeka kwakanaka, kwakakodzera kushandiswa seyakasiyana siyana yekurongedza; BOPP ine kugadzikana kwakanaka kwemakemikari. Kunze kweasidhi yakasimba, yakadai seOleum uye nitric acid, haigadziki mune zvimwe zvinonyungudutsa, uye mamwe mahydrocarbon chete ane kuzvimba pairi; Iyo ine yakanakisa kudzivirira kwemvura uye ndechimwe chezvinhu zvakanakisa zvekunyorova uye hunyoro kuramba, ine mwero wekutora mvura isingasviki 0.01%; Nekuda kwekutadza kudhinda, kurapwa kwepamusoro corona kunofanirwa kuitwa kusati kwadhindwa kuti uwane mibairo yakanaka yekudhinda; Yakakwira static magetsi, Antistatic agent ichawedzerwa kune resin inoshandiswa kugadzira firimu.

kurongedza

Iyo yepamusoro dhizaini yematte BOPP ndeye matte layer, ichiita kuti chitarisiko chinzwe senge bepa uye yakasununguka kubata. Nzvimbo yekutsakatika kazhinji haishandiswe kuvhara kupisa. Nekuda kwekuvapo kwekutsakatika kwemukati, kuenzaniswa neBOPP yakawanda, ine maitiro anotevera: nzvimbo yekuparara inogona kuita shading basa, uye kubwinya kwepamusoro kwakaderedzwawo zvakanyanya; Kana zvichidikanwa, iyo yekutsakatika inogona kushandiswa sevhavha inopisa; Nzvimbo yekutsakatika ine kutsvedzerera kwakanaka, sezvo kukwenya kwepamusoro kune anti adhesion uye firimu roll haisi nyore kunamira; Kusimba kwesimba rekutsakatika kwefirimu rakadzikira zvishoma pane iro remufirimu rakazara, uye kugadzikana kwekupisa kwakatonyanya kuipa kupfuura iyo yeBOPP yakajairwa.

kurongedza

Pearlescent firimu inogadzirwa kubva kuPP seyakagadzirwa zvinhu, yakawedzerwa neCaCO3, pearlescent pigment, uye rabha yakagadziridzwa agent, yakasanganiswa uye biaxially yakatambanudzwa. Nekuda kwekutatamuka kwePP resin molecules panguva ye biaxial kutambanudza maitiro, chinhambwe chiri pakati peCaCO3 particles chinowedzerwa, zvichikonzera kuumbwa kweporous bubbles. Naizvozvo, iyo pearlescent firimu iine microporous furo firimu rine density ye 0.7g/cm ³ Kuruboshwe uye kurudyi.

PP mamorekuru anorasikirwa neayo ekuisa chisimbiso ekupisa mushure meiyo biaxial orientation, asi semamodhifita akadai serabha, achine zvimwe zvekuvharisa zvisimbiso. Nekudaro, simba rekuvhara kupisa rakaderera uye riri nyore kubvarura, richiita kuti riwanzo shandiswa mukurongedza ice cream, popsicles, uye zvimwe zvigadzirwa.

4. Kupisa kwakavharwa BOPP firimu

Kaviri mativi kupisa sealing firimu:

Iri firimu rakatetepa rine chimiro cheABC, iine ese A uye C nzvimbo dziri kuvharwa kupisa. Inonyanya kushandiswa sezvinhu zvekurongedza zvekudya, machira, odhiyo uye vhidhiyo zvigadzirwa, nezvimwe.

Single sided heat sealing film:

Iri firimu rakatetepa rine chimiro cheABB, neA-layer iri iyo yekuisa chisimbiso chekupisa. Mushure mekudhinda maitiro paB-side, inosanganiswa ne PE, BOPP, uye aluminium foil kuti iite bhegi, iyo inoshandiswa seyepamusoro-soro yekuputira zvinhu zvekudya, zvinwiwa, tii, uye zvimwe zvinangwa.

5. Kanda CPP firimu

Cast CPP polypropylene firimu firimu risingatambanudzi, risina kutariswa polypropylene firimu.

Hunhu hweCPP firimu hwakanyanya kujeka, kupfava kwakanaka, kunaka kwepamusoro-tembiricha kuramba, imwe nhanho yekuomarara pasina kurasikirwa nekuchinjika, uye yakanaka kupisa chisimbiso. Homopolymer CPP ine yakamanikana tembiricha renji yekuisa chisimbiso chekupisa uye yakakwirira brittleness, ichiita kuti ive yakakodzera kushandiswa seimwe-layer yekurongedza firimu,

Kuita kwecopolymerized CPP kwakaringana uye kwakakodzera seyemukati layer zvinhu zvecomposite membranes. Parizvino, inowanzoita co extruded CPP, iyo inogona kushandisa zvizere hunhu hweakasiyana polypropylene musanganiswa, ichiita kuti kuita kweCPP kuve kwakazara.

6. Kuvhuvhuta yakaumbwa IPP firimu

IPP inoputika firimu inowanzogadzirwa uchishandisa nzira yekudzika inodzika. Mushure mokunge PP yawedzerwa uye yakawedzerwa pamuromo we annular mold, inotanga kutonhodzwa nemhete yemhepo uye pakarepo inodzimwa uye yakaumbwa nemvura. Mushure mekuoma, inopetwa uye inogadzirwa se cylindrical firimu, iyo inogonawo kuchekwa kuita mafirimu matete. Blow molded IPP ine kujeka kwakanaka, kusimba, uye nyore kugadzira bhegi, asi ukobvu hwayo hwakafanana husina kunaka uye bhaisikopo rakapfava harina kukwana.
