Ngokuqhelekileyo izikrweqe ezibekiweyo zincinci nge-20-40% kuneemveliso ezilukiweyo ezenziwe ngomsonto ofanayo kunye nolwakhiwo olufanayo.
Imigangatho emininzi yaseYurophu ifuna uphahla inwebu ubuncinci bokugqunywa kwemathiriyeli kumacala omabini eskrim. Izikrweqe ezibekiweyo zinceda ukuvelisa iimveliso ezibhityileyo ngaphandle kokwamkela amaxabiso aphantsi obugcisa. Kunokwenzeka ukugcina ngaphezu kwe-20% yezinto eziluhlaza ezifana ne-PVC okanye i-PVOH.
Zizikrelemnqa kuphela ezivumela ukuveliswa kwenwebu ecekethekileyo elinganayo yophahla lwamaleko amathathu (1.2mm) edla ngokusetyenziswa kuMbindi Yurophu. Ilaphu alinakusetyenziselwa ukuphahla inwebu ezibhityileyo kune-1.5mm.
Ubume be-scrim ebekiweyo bubonakala kancinci kwimveliso yokugqibela kunesakhiwo semathiriyeli elukiweyo. Oku kubangela ukuba imveliso yokugqibela ibe lula kwaye icace ngakumbi.
Umphezulu ogudileyo weemveliso zokugqibela eziqulathe ii-laid scrims zivumela ukuwelda okanye ukuncamathelisa iileya zeemveliso zokugqibela ngokulula nangokuzinzileyo kunye nomnye.
Imiphezulu egudileyo iya kuxhathisa umhlaba ixesha elide kwaye ngokuqhubekayo.
