Nekukurumidza kusimukira kwehupfumi hwemagariro, kurongedza mapepa kwakatora chinzvimbo chakakosha muzvinhu zvakasiyana-siyana zvekurongedza, kunyanya zvigadzirwa zvakatevedzana zvemidziyo yemapepa. Mapepa emidziyo anogona kugadzirwa nenzira dzakasiyana-siyana semabhokisi, makapu, mbiya, etc. Nekuti chigadziko chebepa pachacho chine hunhu hwekuchengetedza, hutsanana, husina chepfu, husina kunhuhwirira, husina kusvibiswa, husina kunaka, zvichingodaro, zvinoenderana ne ikozvino kuchengetedza kwezvakatipoteredza maitiro uye ndeye yakachengeteka yekurongedza zvinhu iyo inoshandiswa zvakanyanya mukurongedza chikafuindustry.
Nekuda kweakasiyana mafomu ekugadzirisa emidziyo yemapepa, kune zvakare zvakasiyana zvinodiwa zvebepa, saka zvakakosha kuti uzive hunhu hwecupstock yekumashure-kugadzirisa. Inowanzoshandiswa pamakapu emapepa uyembiya dzepepa.
Izvo zvinhu zvinoshandiswa kumakapu ekunwa zvinopisa zvinowanzogadzirwa nebepa repasi uye imwechete PE coating, inova imwe chetePE yakavharwa cupstock . Kazhinji, inodhindwa pane isiri-PE bepa pamusoro. Nekuda kwezvinodiwa zvezvinwiwa zvinopisa, zvigadzirwa zvakadaro zvinoda kuve nehumwe dhigirii rekupisa kupisa mushure mekugadzirisa. Nokudaro, zvigadzirwa izvi zvinowanzoda humwe hutete uye kuoma kwepepa kuti uwedzere kupisa kwekushisa. Iyo yakakura vhoriyamu, iyo yakakora bepa rinoshandiswa.
Cold drink cups yakakamurwa kuva marudzi maviri nekuda kwenzira dzakasiyana dzekugadzirisa. Imwe ndeyekugadzira bepa rine anti-permeability zvakanaka kuburikidza nenzira yekunyikwa wakisi mushure mekunge bepa repasi radhindwa uye raitwa kapu; imwe yacho ndeyekuita kuti bepa risapindike nekubatanidza PE kumativi ese epepa. Zvinodiwa zvekudhinda zvemhando mbiri dzakasiyana dzekugadzirisa zvinhu zvakasiyana. Kudhinda kunoitwa nenzira yekunyika wakisi kunodhindwa pabepa. Nezve kudhinda pachayo kune chekuita, hapana zvakakosha zvinodiwa kune iyo mbishi zvinhu. Kune bepa mushure meviri-sided PE musanganiswa, zvinodikanwa kusanganisa bepa nekurapa kwakakosha kuitira kuti uwane yakanaka yekudhinda maitiro.
Cupstock inoshandiswa zvakanyanya muindasitiri yekurongedza chikafu, saka kusarudzwa kweinki hakungoenderane nezvinodiwa zvekudhinda pachayo, asi kunodawo kuti zvikamu zveinki zvinofanira kusangana nemutemo wehutsanana hwekudya uye chikafu chekurongedza utsanana. Kushandiswa kwezvinonyungudutsa kunoda kusanhuhwirira kunhuhwirira uye chidimbu chidiki chezvinonyungudutsa, kuitira kuti zvigadzirwa zvakadhindwa zviomeswe nekukurumidza uye kudzivirira matambudziko akadai sekusanamatira kwakashata kunogona kuitika panguva inotevera yekugadzira kapu.
