Makapu epepa ave chikamu chakakosha chehupenyu hwedu hwezuva nezuva uye anoshandiswa zvakanyanya pasi rese. Makapu epepa anogona kuonekwa kwese kwese, kungave muindasitiri yekubika kana munzvimbo dzekugara dzakadai semakambani kana mhuri.
Chinhu chikuru chinoshandiswa mukugadzira makapu epepa ipepa rakaputirwa nePE. PE inomiririra polyethylene, thermoplastic polymer inopa kapu rukoko rusingapindi mvura. Rukoko urwu runovimbisa kuti kapu inoramba yakasimba uye isingadonhe mvura, zvichikubvumidza kuti unakirwe nechinwiwa chako pasina kunetseka.
GSM (kana magiramu pa square meter) ndiyo nzira yekuyera nayo bepa. Kana GSM yakakwira, bepa racho rinokora uye rinogara kwenguva refu. Kune makapu epepa, GSM iri pakati pe 170 ne 350 ndiyo inowanzo shandiswa. Muunganidzwa uyu unovimbisa kuti makapu acho akaenzana zvakakwana pakati pekusimba uye kuchinjika, zvichiita kuti zvive nyore kubata uye kudzivirira chero kubuda kwemvura.
Asi sei GSM range ichikosha pamakapu epepa? Chinangwa chikuru, saka, ndechekuona kuti kapu inogona kutakura huremu hwechinwiwa uye isingakanganise kana kuparara nekuda kwehunyoro. GSM yakakwira inopa kapu simba rinodiwa uye kuomarara, zvichiita kuti igone kutakura zvinwiwa zvinopisa pasina dambudziko. Kune rumwe rutivi, GSM yakaderera inogona kuita kuti kapu isanyanya kusimba uye ive nyore kudonha.
Maitiro ekuputira pepa nePE anoshandiswa kugadzira makapu epepa. Maitiro aya anosanganisira kuputira bepa ne polyethylene kuti riwedzere simba raro rekudzivirira mvura uye kudzivirira kupisa. Kuputira PE kunodzivirira hunyoro kuti husapinde mubepa uye kunochengetedza tembiricha yakakodzera yezvinwiwa, zvichiita kuti zvigare zvichipisa kana kutonhora kwenguva yakareba.
Zvakakosha kuti PE coating iiswe zvakaenzana pamusoro pepepa. Izvi zvinoita kuti kapu irambe isingadonhe uye inodzivirira kudonha kwemvura kusingadiwe. Ukobvu hwePE coating inowanzova 10 kusvika 20 microns, zvichienderana nemhando uye mashandiro anodiwa ekapu. Iyi PE-coated bepa inowanzonzi "single-sided PE coating paper" kana "double-sided PE coating paper", zvichienderana nekuti coating yacho yakaiswa kupi.
Pamusoro pekuputira GSM nePE, zvimwe zvinhu zvinokanganisawo kunaka uye mashandiro emakapu emapepa. Hunhu hwezvinhu zvemakapu emapepa, maitiro ekugadzira uye dhizaini yemafeni emakapu emapepa zvine basa guru. PaperJoy anga achigadzira pepa rakaputirwa nePE, feni yekapu yepepa nezvimwe zvinhu zvemapepa zvakagadzirwa kwemakore gumi nemanomwe, uye zvinopa mienzaniso yemahara kuitira kuti ugone kuona zviri nani mhedzisiro yakakwana yechigadzirwa.
