Bubble yekuvharira inochinjika kurongedza ndeye inoshandiswa zvakanyanya mishonga yekunze yekurongedza zvinhu, nguva zhinji ndeyekusiyana kwezvinhu zvinoumba kugadzirwa, iyi plastiki sheet zvinhu PTP aluminium blister foil chivharo chiputiriso chinoshandiswa mune hwaro zvinhu, iyo inonyanya kuzivikanwa ndeye polyvinyl chloride hard sheet (PVC hard sheet kwenguva pfupi), bubble cover packaging yapfuura kwenguva yakareba, Kubva pakagamuchirwa blister packaging kugadzirwa, hwaro – PVC zvinhu zvinoshandiswa kupedzisa blister kurongedza kwemishonga. Izvo zvinhu zvine zvinhu zvakawanda zvakanaka uye zvakachipa uye zvemhando yepamusoro, asi inewo zvimwe zvisinganyanyi kujeka. Semuyenzaniso, Kugadzirwa kwePVC kana kushandiswa kwemaitiro kuchave nekukanganisa nharaunda. Panguva yekugadzirwa, mamwe magasi asingadikanwi evinyl chloride dzimwe nguva anogadzirwa pamwe chete nemimwe musanganiswa.

Kugadzirira kwe mushonga PVC inoda kuwedzera zvimwe zvikamu, zvakadai seplasticizer, stabilizer, zvichingoenda zvakadaro. Chigadzirwa chacho chakagadzikana mukushanda uye hachizokonzeri kukanganisa kwakananga kumuviri wemunhu, asi mushure mekushandisa, dzimwe nzvimbo dzichapiswa mukugadziriswa kwemarara ekurongedza, uye kupisa kwePVC kuchagadzira zvigadzirwa se dioxin hydrochloric acid. Izvi zvine zvimwe zvinokanganisa zvakatipoteredza.

Dzimwe nyika nematunhu, kuitira kubvisa kubuda kwemhando iyi yezvinosvibisa, vakamisa kushandiswa kwePVC blister packaging, semamwe makambani emishonga muGermany. Nyika yeJapan zvakare inodzikamisa kugadzirwa kwePVC zvigadzirwa, izvi ndezvevose vanogadzira mishonga kuti vacherechedze, Ikozvino kushandiswa kwakapararira kwePVC mapepa semishonga inoputira blister inogona kunge iri nekuda kwekuti nharaunda kana kugadzirwa kwezvimwe zvinhu zvinokuvadza uye zvishoma nezvishoma kuderedza kushandiswa., kana ramangwana mune iyi fomu risina kuvandudzwa, chigadzirwa ichi chichabviswa zvishoma nezvishoma.

Kuti uvandudze zvirinani zvikanganiso zvemishonga PVC zvinhu, kuitira kuti chinyorwa ichi chikwanise kuita zviri nani zvinodiwa zvepakiti yemishonga, mafekitari emishonga ave kutanga kushandisa PVC composite hard sheet, Iri pepa rinoumbwa rinonyanya kuumbwa nePVC hard sheet uye imwe kana akati wandei mapolymer zvinhu mafirimu, firimu rekusanganisa. By extrusion, composite, kuunganidza, machining nzira yekugadzira uye musanganiswa mutsva wekusangana nezvinodiwa zvemishonga yekurongedza zvinhu pamusika parizvino yakakurumbira blister packaging ndeye aluminium pepa repurasitiki., rudzi urwu rwealuminium foil pachayo, non-chepfu, uye nemvura, oxygen insulation performance yakanaka, mishonga uye inogona kuva nguva yakareba mushure memishonga yemishonga. Hazvizove nyore kutora unyoro, chakuvhe, kudzikira, etc., kunyanya kune Traditional Chinese mushonga, zvinodiwa zvekutakura zvinhu zvinonyanya kudiwa.

Pakaiswa mushonga muma1990s, kuchengetedzwa kwekushandisa zvinodhaka zvakanyanya uye zvakanyanya mabhizinesi uye vatengi vanoteerera, nekuti zvimwe zvinoumba zvinodhaka zviri panjodzi yekusagadzikana, oxidation, pepa rekutanga rePVC ratadza kuzadzisa zvinodiwa zvekurongedza zvemishonga iyi. Fekitori yemishonga yakabudirira kugadzirwa kuPVC yakaoma pepa sechinhu chekutanga, pane yekutanga hwaro yekuwedzera imwe yakakwirira chipingamupinyi polymer zvinhu zvinoumbwa, wedzera iyo yekutanga PVC mune ese maficha ehunhu, sePVC uye PVDC inoumbwa, PVC uye PE composite, PVC/PE/PVDC composite uye zvichingodaro. Izvi zvinosanganiswa zvinhu zvinosanganisa kuomarara kwePVC hard sheet, Kuumbwa kwakanaka, uye chidziviso chakanaka kumhute yemvura, oksijeni, carbon dioxide gasi, nekunhuhwirira kwemarudzi ose. Inogona kunyatso kuzadzisa zvinodiwa zvekurongedza zvemishonga iri nyore uye nyore oxidized uye mimwe mishonga yechinyakare yechiChinese inoda kuchengetedza hwema.. Panguva imwe, kushandiswa kweaya madhisiki anoumbwa anochengetedza ekutanga ekugadzira michina, apo ichideredza mufananidzo wezvakatipoteredza.
