Miyeso kuti muchepetse screac shrink shring shring shring ndi kumasula: chitsulo chosungunuka chimayambitsidwa munthawi yomweyo kuti muchepetse chimbale cha pack ndikuletsa mapangidwe owumbika. Malinga ndi malingaliro oyenera okhazikika pazachitsulo, magawo ang'onoang'ono ocheperako, omwe amakulirakulira, ndipo kutsimikizika kozama pa shrinka. Makina odyetsa amatha kukhala achikondi kudyetsa kapena kudyetsa mkumbwe. Dongosolo lodyetsa mitu likutengera, mutu wakhwima ukhoza kuwonjezeka bwino, monga kuwonjezera kutalika kwa bokosi lapamwamba, kuwonjezera mphete ya pachipata, ndi zina; Wothamanga pamtanda ndiye gawo lalikulu la skiming ndi mpweya woyandama. Pamene imagwiritsidwa ntchito powonjezera shrinkage, kukula kwake kumatha kuwonjezeka; Zowopsa zamkati zikhala zazifupi, zowonda komanso zazikulu. Mawonekedwe amkati ndi afupifupi (zotulukapo zowonjezera zili pafupi ndi kuponyera). Chifukwa cha mphamvu yoponyera ndi yopingasa yoponyera ndi mphamvu ya chitsulo chotsuka ndikumadyetsa, ndipo zimatsekedwa pasadakhale, ndipo sizingatsegulidwe kwa nthawi yayitali. Owonda (nthawi zambiri) amatha kuletsa kulumikizana ndi kulumikizana kotentha koyambirira kwa mtima. M'lifupi ndikuwonetsetsa kuti ndi malo okwanira. Kuponyera kumalowa gawo lolimba la kufalikira ndi kuphatikizira, chitsulo chosungunulira chizikhala kuti chikuyenda bwino, zomwe zimasinthasintha nthawi yayitali (khosi lokhazikika) pakudyetsa. Kwa zinyalala zina zokhala ndi shrinkager zazikulu, wokwerayo amatha kudyetsa. Mphezi imayamba bwino kwambiri kumayambiriro kwa masitepe amkati, kapena wopondaponda ukhoza kukhala pakatikati kuti adyetse disc mbali imodzi ya mliri umodzi wamkati. Kwa magawo ocheperako ocheperako, njira zachiwiri zoponyera zitha kuteleredwa, ndiye kuti, kungozindikira zitha kuwonjezeredwa mu phukusi laling'ono kuti lizisintha ndikulimbikitsa nyukiliya komanso kukula kwa gravite. Itha kuwonjezeredwa pansi pa phukusi ndikutsuka mu chitsulo chofewa.
