Pepa remukombe wePE inzira yekuvandudza uye eco-inoshamwaridzika kune yechinyakare makapu epurasitiki. Yakagadzirwa nemhando yakakosha yemapepa akaputirwa nechidimbu chepolyethylene, zvichiita kuti isapinda mvura uye yakanakira kushandiswa sekapu inoraswa. Iko kuvandudzwa kwePE mukombe bepa kwave rwendo rurefu uye runonakidza uine matambudziko mazhinji uye mabhindauko munzira.
Nhoroondo yePE cup bepa inogona kuteverwa kumashure kwekutanga 1900s, apo makapu emapepa akatanga kuunzwa sehutsanana uye yakanakira imwe nzira kune ceramic kana girazi makapu. Nekudaro, aya makapu ekutanga emapepa akange asina kusimba zvakanyanya uye aive netsika yekudonha kana kudonha kana akazara nezvinwiwa zvinopisa. Izvi zvakaita kuti pave newax-coated paper cups muma1930s, ayo ainyanya kurwisa zvinwiwa nekupisa.
Mumakore ekuma1950, polyethylene yakatanga kuunzwa sechinhu chekuputira pamakapu emapepa. Izvi zvakabvumira kugadzirwa kwekapu dzaive dzisingapindi mvura, dzisingapise kupisa, uye dzine hushamwari hwezvakatipoteredza kupfuura makapu akavharwa nenamo. Nekudaro, hazvina kusvika kuma1980s apo tekinoroji nekugadzira nzira dzinodiwa pakugadzira bepa remukombe wePE pamwero mukuru dzakagadzirwa zvizere.
Imwe yematambudziko akakosha mukugadzira PE mukombe bepa kwaive kuwana chiyero chakakodzera pakati pesimba uye kuchinjika. Bepa racho raifanira kunge rakasimba zvakakwana kuti ribate zvinwiwa zvisingabvi kana kudonha, asi zvakare kuchinjika zvekukwanisa kuumbwa kuita kapu isina kubvaruka. Rimwe dambudziko raive rekutsvaga zviwanikwa zvaidiwa kugadzira bepa remukombe wePE muhuwandu. Izvi zvaida kushandira pamwe kwezvigayo zvemapepa, vagadziri vepurasitiki, nevagadziri vemakapu.
Kunyangwe zvipingamupinyi izvi, kudiwa kweeco-hushamwari uye inogoneka dzimwe nzira dzechinyakare makapu epurasitiki zvakaramba zvichikura mumakore achangopfuura. Pepa remukombe wePE rave kushandiswa zvakanyanya muzvitoro zvekofi, cheni dzechikafu chekukurumidza, uye mamwe maindasitiri ebasa rekudya seimwe sarudzo ine hushamwari. Iri kuwedzerawo mukurumbira pakati pevatengi vane hanya nekukanganisa kwemarara epurasitiki pane zvakatipoteredza.
Mukupedzisa, kuvandudzwa kwePE kapu bepa rave rwendo rurefu uye rwunonakidza rwave kuda makore mazhinji ekutsvaga nekusimudzira. Nekudaro, mhedzisiro ndeye chigadzirwa chine ushamwari kwezvakatipoteredza uye hupfumi hunoshanda. Sezvo kudiwa kwevatengi kwe eco-inoshamwaridzika zvigadzirwa kuri kuramba kuchikura, zvingangoita kuti tichaona zvakatowedzera kufambira mberi mukuvandudza nekugadzirwa kwezvigadzirwa zvakasvibirira sePE cup bepa.
